2 Installation Chapter 2, Installation, provides information and procedures for inspecting, installing, and testing the power supply.
Installation Basic Setup Procedure Table 2-1 provides a summary of the basic setup procedure with references to the relevant sections in this chapter. Refer to this table if you are unfamiliar with the installation requirements for the power supply. Complete each step in the sequence given. Table 2-1 Basic Setup Procedure Step Description Action Reference 1 Inspect Inspect the power supply. “Step 1: Inspecting and Cleaning” on page 2–3. 2 Install Install the power supply (benchtop or rack mount).
Step 1: Inspecting and Cleaning Step 1: Inspecting and Cleaning Initial Inspection When you first receive your unit, perform a physical check: 1. Inspect the unit for any scratches and cracks, broken switches, connectors or displays. 2. Ensure that the packing box contains the 7.5 foot (2.5 m) power cord. 3. If you see external damage or suspect internal damage, contact Xantrex Customer Service (see Contact Information on page iii) for an assessment.
Installation Step 2: Location and Mounting The power supply may be rack-mounted or used in benchtop applications. Rack Mounting The XG 850 Watt power supply is designed to fill half of a standard 19 inch (483 mm) equipment rack. Units can be combined with the same models in the 850 W series for customer applications. Purchasing Rack Mount Kits Contact Xantrex Customer Service (see “Contact Information” on page iii) about purchasing the Rack Mount Kit options for XG 850 Watt.
Step 3: Connecting AC Input Power Step 3: Connecting AC Input Power WARNING: Shock hazard Disconnect AC power from the unit before removing the cover. Even with the front panel power switch in the Off position, live line voltages are exposed when the cover is removed. Repairs must be made by an Authorized Service Center. WARNING: Shock hazard There is a potential shock hazard if the power supply chassis and cover are not connected to an electrical ground via the safety ground in the AC input connector.
Installation Step 4: Selecting Load Wires This section provides recommendations for selecting minimum load wire sizes. Load Wiring To select the wiring for connecting the load to the power supply, consider the following factors: • • • • Insulation rating of the wire. Current carrying capacity of the wire. Maximum load wiring length for operation with remote sense lines. Electrical noise and impedance effects of the load lines.
Step 4: Selecting Load Wires Maximum Load Wiring Length For Operation With Sense Lines 2 Figure 2-1 Maximum Load Wire Length for 1 V Line Drop Noise and Impedance Effects To minimize noise pickup or radiation, use shielded twisted pair wiring of the shortest possible length for load sense wires. Connect the shield to the power supply chassis. Where shielding is impossible or impractical, simply twisting the wires together will offer some noise immunity.
Installation Step 5: Performing Functional Tests The functional test procedures include: • • Power-on and front panel functional checks Voltage mode operation and current mode operation checks. For information on local operation, see “Local Operation” on page 3–1 for adjusting front panel controls and settings. Powering the Power Supply On/Off To power on the power supply: 1. Ensure that the front panel power switch is in the Off position. 2. Ensure that the AC line voltage is within operating range. 3.
Step 5: Performing Functional Tests Voltage and Current Mode Operation Checks To perform the voltage and current mode operation checks: 1. Ensure that the front panel power switch is in the On position and the output is disconnected. 2. If the OUTPUT ENABLE Main button is illuminated, press the button to turn off the output. 3. To check voltage mode operation, turn the 9-position mode control to the VOLTS position. The voltage set point will blink dimming and then return to full brightness.
Installation Step 6: Connecting Loads This section describes how to connect loads to the power supply for both single and multiple loads. WARNING: Shock hazard There is a shock hazard at the power supply output when operating at an output greater than 40 V. To protect personnel against accidental contact with hazardous voltages, ensure that the load and its connections have no accessible live parts.
Step 6: Connecting Loads Inductive Loads and Batteries CAUTION The XG power supply requires freewheeling and blocking diodes across the output while driving inductive loads or batteries to protect the power supply from damage caused by power being fed back into the supply and from high voltage transients. Selecting Diodes The diode must have a voltage rating at least 20% greater than the power supply's output voltage and have a current rating greater than or equal to the power supply's output rating.
Installation Connecting Single Loads Figure 2-3 shows the recommended load connections for a single load which is sensing its voltage locally. Local sense lines shown are the default connections at the rear panel APG J1 connector (see Figure 4-1 on page 4–5). The load lines should use the largest gauge and shortest length of wire possible to ensure optimal performance. You do not need remote sensing for basic operation of your power supply.
Step 7: Connecting Remote Sensing Step 7: Connecting Remote Sensing WARNING: Shock hazard There is a potential shock hazard at the sense connectors when using a power supply at an output greater than 40 V. Select wiring with a minimum insulation rating equivalent to the maximum output voltage of the power supply for use as local sense jumpers or for remote sense wires. Ensure that connections at the load end are shielded to prevent contact with hazardous voltages.
Installation 3. Connect one end of the shield of the twisted pair wire to the chassis ground point on the power supply. 4. Connect the positive sense line (+SNS) from the positive regulation point as close as possible to the load terminals to pin J1.1. 5. Connect the negative sense line (–SNS) from the return of the load to pin J1-6. To compensate for losses in power leads connected to the output, the power supply provides sense connections beside the output terminals.
3 Local Operation Chapter 3, Local Operation, provides the procedures for local (front panel) operation such as: • Configuring settings. • Operating in constant voltage mode and constant current mode. • Using the protection features. • Using multiple power supplies.
Local Operation Introduction Once you have installed the power supply and connected both the AC input power and the load (covered in “Installation” on page 2–1), the power supply is ready for local operation. To turn the power supply on, see “Powering the Power Supply On/Off” on page 2–8. Configuring Settings from the Front Panel Using the 9-Position Mode Control The 9-position mode control is used with the rotary Adjust/Enter control to configure settings in local operation.
Configuring Settings from the Front Panel Coarse and Fine Adjustment Modes The coarse and fine adjustment modes are used for setting the voltage and current set points, OVP and UVP settings. Coarse adjustment mode When using local operation to set the current and voltage set points, use the coarse adjustment mode (default) followed by the fine adjustment mode (see next). The coarse adjustment mode quickly adjusts the settings in large increments to reach the desired value.
Local Operation Table 3-1 Select and Set from the Front Panel 9 Positions on the Mode Control Knob Turning the rotary Adjust/Enter control lets you… Pressing the rotary Adjust/ Enter control lets you… CAP (Current Analog Programming) Select the programming source and select the range. Set the value selected and cycle to the next setting. VAP (Voltage Analog Programming) Select the programming source and select the range. Set the value selected and cycle to the next setting.
Navigating the Menu System Navigating the Menu System The menu system of the XG follows a select and set model with the exception of the VOLTS and AMPS modes. See “Setting VOLTS and AMPS Modes”. The general procedure for setting up the features in the select and set model is: 1. To select a mode, rotate the 9-position Mode control to the desired mode or press the rotary Adjust/Enter control once to activate the current selection on the mode control knob. See Figure 3-3. 2.
Local Operation To access the tracking mode for entering voltage and current: 1. Select the VOLTS or AMPS position on the 9-position mode control. If the set point is blinking, the unit is in coarse tracking mode. • • When the VOLTS mode is selected, the voltage set point will blink in the output voltage display. When the AMPS mode is selected, the current set point will blink in the output current display. 2. Use the rotary Adjust/Enter control to adjust the set point.
Navigating the Menu System Normal Display Mode and Inactivity Timeout Normal display mode appears on the output voltage and current displays when the configuration changes from the front panel have been completed or when the inactivity timeout occurs (default is 3 seconds). Normal display mode shows the output voltage and current values. If a timeout occurs before the changes made to the value have been set, the changes will not be saved and you will have to re-enter the changes.

Standard Operation Standard Operation The power supply can be controlled by two methods, either from the front panel or from any of the remote interfaces. Front panel control is referred to as local operation (default setting) while control via any of the remote interfaces is called remote operation. To set up the power supply for remote operation, see Chapter 5, “Remote Operation”.
Local Operation Constant Voltage Mode Operation If the output is enabled and the configured current set point is much higher than the requirements for the attached load, then the voltage will rise until it reaches the voltage set point. When the output voltage reaches the voltage set point, it stops rising. The unit will continue to operate in CV mode. The load current will still vary to meet any changes in required load current draw resulting from a change in the attached load.
Standard Operation 3 Figure 3-4 Operating Modes To set the voltage set point (VSET): 1. Turn the 9-position mode control to the VOLTS position or press the rotary Adjust/Enter control if the 9-position mode control is already at the VOLTS position. The voltage set point is blinking in the output voltage display. The output current will be displayed in the output current display. 2. Set the desired voltage value using the rotary Adjust/Enter control.
Local Operation Important: The control circuits have been designed to allow you to set the output voltage up to 105% over the model-rated maximum value. The power supply will operate within these extended ranges, but full performance to specification is not guaranteed. Quick Tip Remote operation uses these SCPI commands. See page 5–1.
Enabling the Output Shipped Configuration (Local Operation) The power supply is configured for local operation at the factory. See Table 3-3 for a summary of this configuration. For more information on default settings, see Table 3-9 on page 3–39. Table 3-3 Shipped Configuration Local Control Configuration Additional References Use the front panel controls to adjust the output voltage and current set point settings. See Chapter 3, “Local Operation” for front panel operation.
Local Operation Enabling the Auxiliary Output To enable on the auxiliary output: ◆ Press the OUTPUT ENABLE Aux button on the front panel. The OUTPUT ENABLE Aux button will illuminate. Important: The auxiliary output will not be enabled if the external AUX_ON_OFF signal line is being used to disable the auxiliary outputs. See “AUX Output and Isolated Analog Programming (ISOL) Connector” on page 4–20. To disable the auxiliary output: ◆ Press the OUTPUT ENABLE Aux button on the front panel again.
Auxiliary Auto Start Mode Auxiliary Auto Start Mode The Auxiliary Auto Start mode determines the state of the auxiliary output after a complete power cycle (all front panel LEDS are not illuminated). With Auxiliary Auto Start mode turned to On, the auxiliary output will be activated after the power supply is powered up again. To define the Auxiliary Auto Start mode: 1. Press and hold the OUTPUT ENABLE Aux button for 1 second. AuAS On or AuAS Off is displayed. 2.
Local Operation Alarms and Errors Several conditions can cause alarms in the XG. Some conditions are: • • From user configurable features. Controlled in hardware and will trigger regardless of configuration. All alarms, with the exception of the Fan alarm, will result in the output of the power supply being disabled. The Fan alarm does not affect the output. When an alarm is triggered, the appropriate alarm message will begin blinking on the display and the Alarm LED will be illuminated.
Alarms and Errors Clearing Alarms Clearing Triggered and Manual Alarms To clear a triggered alarm, use one of the following methods: • Turn the power supply Off and then On. • Press and hold the rotary Adjust/Enter control for 3 seconds. • Press the reset key combination (Flash Fail ONLY). See “Resetting the Power Supply” on page 3–39. To clear a manual alarm: 1. Press and hold the rotary Adjust/Enter control for 3 seconds. The ALr CLr message will be displayed on the front panel for a few seconds.
Local Operation Clearing Automatic Alarms Some alarms will clear automatically when the condition that caused the alarm is no longer present. When an alarm automatically clears, the output voltage and current displays will return to normal, but the ALARM LED will remain illuminated to indicate that an alarm has occurred. If an automatic alarm is triggered, the normal alarm clearing procedure still applies.
Alarms and Errors Alarm Masking It is possible to completely disable some alarms through the use of the alarm mask. If an alarm is masked then this masking will prevent it from registering in the SCPI conditions registers as well as not triggering the alarm. The alarms that can be masked are identified in Table 3-4 on page 3–18. Setting the bit position (1) of an alarm will result in the alarm being enabled. Clearing the bit position (0) of an alarm will result in the alarm being masked/disabled.
Local Operation Alarm Output Latching When an alarm is triggered, the output will be disabled with the exception of the Fan alarm. When an alarm is cleared, the alarm output latch determines if the output should be re-enabled to the state before the alarm occurred or if the output should remain in the off state.
Setting Foldback Mode Setting Foldback Mode Foldback mode is used to disable the output when a transition is made between the operating modes. The power supply will turn off/disable the output and lock in foldback mode after a specified delay if the power supply transitions into CV mode or into CC mode, depending on the foldback mode settings. This feature is particularly useful for protecting current or voltage sensitive loads.
Local Operation 4. Press the rotary Adjust/Enter control to commit the setting once the desired value has been set. 5. The green FLD LED will turn off and the display will return to the normal display mode.
Using Over Voltage Protection (OVP) Using Over Voltage Protection (OVP) The OVP circuit protects the load in the event of an analog programming error, an incorrect voltage control adjustment, or a power supply failure. The OVP circuit monitors the output voltage at the output of the power supply and will disable the output whenever a preset voltage set point is exceeded.
Local Operation Defining the OVP Set Point To define the OVP set point: 1. Turn the power supply On. Ensure the voltage is lower than the desired set point. 2. Set the output to the desired voltage. OVP can be set without setting desired output voltage first. 3. Turn the 9-position mode control to the PRT position. Pro OUP is displayed. 4. Press the rotary Adjust/Enter control. 5. Turn the rotary Adjust/Enter control to set the upper limit protection. See “Coarse and Fine Adjustment Modes” on page 3–3.
Using Under Voltage Protection (UVP) Using Under Voltage Protection (UVP) Important: UVP will not be active for voltage set points that are less than 1% of model voltage. The UVP prevents voltage settings below a set value. The UVP lets you create a voltage window of operation when used in conjunction with the OVP setting. The UVP range is variable from 0 V to OVPSET –10%.
Local Operation Defining the UVP Set Point To define the UVP set point: 1. Turn the power supply On. 2. Set the output to the desired voltage. 3. Turn the 9-position mode control to the PRT position. PRo OUP is displayed. 4. Turn the rotary Adjust/Enter control until PRo UUP is displayed. 5. Press the rotary Adjust/Enter control to select the UVP for setting up. 6. Set up the lower limit protection using the rotary Adjust/Enter control. Important: The UVP range is variable from 0 volts to OVPSET –10%. 7.
Using Over Temperature Protection Lock (OTP) Using Over Temperature Protection Lock (OTP) The OTP lock protects the power supply in the event of an over temperature alarm. This alarm could be caused by ventilation restriction or overheating due to fan failure. Two modes are available: • • Auto recovery (OTP OFF) where the power supply turns on again after cooling down. Latch mode (OTP ON) where you will need to reset the unit by turning the front panel power switch to Off and then On again.
Local Operation Using the External Shutdown Function Use the external shutdown function to enable or disable the output of the power supply via a logic level signal. When the external shutdown is triggered, the power supply will display SD POL on the output voltage and current displays and the ALARM LED will illuminate.
Using the External Shutdown Function Defining the Polarity of the External Shutdown Signal 1. Turn the 9-position mode control to the PRT position or press the rotary Adjust/Enter control if the control knob is already at the PRT position. PrO OUP is displayed on the output voltage display. 2. Turn the rotary Adjust/Enter control until PrO SD is displayed. 3. Press the rotary Adjust/Enter control to display SD 0 (shutdown on logic 0) or SD1 (shutdown on logic 1). 4.
Local Operation Interlock Function The Interlock function can be used to wire an external shutoff switch that can be used to enable or disable the power supply output. When the switch is closed the power supply will operate normally. If the switch is opened, the power supply will trigger the interlock alarm. The output will be disabled, the display will blink In Loc, and the ALARM LED will illuminate.
Hardware Malfunction Alarms Power On Status Signal Power On Status signal indicates a fault condition in the power supply. Power On Status signal is a TTL output signal at Pin J2.13 with reference to COM_ISOLATED (Pin J2.2 or Pin J2.6). During normal operation, the Power On Status signal will be high. If the output is disabled for any reason, the Power On Status signal will go low.
Local Operation Current Configuration Memory Settings The power supply will save the unit settings at the time of power down. These settings will be loaded when the power is restored to the unit or the power supply is powered up again. Table 3-7 lists the settings that are saved and recalled on a power cycle event.
User Setting Memory Locations User Setting Memory Locations There are three user setting memory locations available for storing frequently used configurations. These user setting memory locations help to facilitate multiple users of an XG power supply who have different setups or when multiple loads are used that have different requirements. Table 3-8 lists the values that are stored in each user setting memory location.
Local Operation 4. The setting has now been saved to the selected user setting memory location. The SCPI command (s) for these instructions are: *SAV or [:]SYSTem[]:SAVE Recalling User Setting Memory Locations This feature recalls settings that were previously saved. To load user setting memory locations: 1. Turn the 9-position mode control to the RCL position. RCL is displayed on the output voltage display with a number indicating a preset position on the output current display. 2.
Local Lockout Local Lockout Local lockout is a feature that allows the front panel to be locked so that accidental button presses are ignored. This feature is often used to lockout the front panel when you are controlling the power supply from a remote location. When in local lockout mode, the front panel will display LOCL Loc whenever a button is pressed or a knob is turned. Enabling Local Lockout To enable local lockout: 1.
Local Operation The SCPI command (s) for these instructions are: [:]SYSTem[]:REMote:STATe 3-38 M370078-01
Resetting the Power Supply Resetting the Power Supply The reset is used to clear the parameters to the factory default values. Soft Reset The soft reset is used to set the parameters (see Table 3-9) to the default values, but it does not reset the calibration constants To perform a soft reset: 1. Turn the power supply to Off then On. When the unit is powering on, 8888 8888 is displayed on the output voltage and current displays. 2.

Using Multiple Power Supplies Using Multiple Power Supplies WARNING: Shock hazard There is a shock hazard at the load when using a power supply at an output of greater than 40V or a combined output of greater than 40V. To protect personnel against accidental contact with hazardous voltages created by a series connection, ensure that the load, including connections, has no live parts which are accessible.
Local Operation Power Supply V Common Load V Power Supply Figure 3-5 Split Supply Operation 3-42 M370078-01
Using Multiple Power Supplies Configuring Multiple Supplies for Series Operation A maximum of two power supplies of the same rating can be connected in series to increase the output voltage. CAUTION: Equipment damage When two power supplies are connected in series, they should be programmed to the same output voltage to prevent damage to the lower voltage supply at short circuit condition.
Local Operation Connecting to the Load in Remote Sensing Mode Connect the negative (–) output terminal of one power supply to the positive (+) output terminal of the next power supply. The more positive supply’s positive sense line should connect to the positive terminal of the load (or distribution point). Its return sense line should connect to the connection between the two units at the same spot as the negative supply’s positive sense line.
Using Multiple Power Supplies Configuring Multiple Supplies for Current Sharing Operation (APG Method) Up to four power supplies can be connected in parallel to increase the output current. One of the units will operate as the master unit and the remaining units will operate as slave units controlled by the master unit. The master unit uses the analog programming lines to set the output voltages and currents of the slave units to match its output.
Local Operation Important: The slave unit discussed here is not the same as the remote interface slave described in chapter 5. Setting Over Voltage Protection (OVP) The master unit’s OVP should be programmed to the desired OVP level. The OVP of the slave units should be programmed to a higher value than the master OVP. When the master unit shuts down, it will program the outputs of the slave units to zero volts.
Using Multiple Power Supplies Connecting to the Load in Local Sensing Mode (Parallel Control Method) Connect the power supplies in parallel to obtain a single output supply with a higher output current set point. Set all of the outputs to the same voltage before connecting the positive (+) and negative (–) terminals in parallel. The total current available is the sum of the maximum currents of each power supply.

4 Analog Programming (APG) and Isolated Analog Programming (ISOL) Chapter 4, Analog Programming (APG) and Isolated Analog Programming (ISOL), provides information and procedures for analog and isolated analog programming of the power supply.
Analog Programming (APG) and Isolated Analog Programming (ISOL) Introduction The rear panel connectors J1 and J3 provide an option to control and monitor the output of the power supply with analog signals. Connector J1 provides a non-isolated analog interface where all signals are referenced to the negative output terminal of the power supply. Connector J3 is an isolated interface and also provides an isolated auxiliary voltage output to aid analog programming.
Introduction Remote Programming Options Analog Monitor Signals There are four monitor lines for analog programming the pin name and the related APG mode, which are listed in Table 4-1. All of these lines are provided to give analog feedback. The output from these monitor lines is a value scaled to the Analog Programming level set for the corresponding analog programming type.
Analog Programming (APG) and Isolated Analog Programming (ISOL) Auxiliary Outputs The auxiliary outputs are an additional isolated source. The auxiliary output has two outputs: +5 V output on J3.9 and a +15 V output on J3.11. The auxiliary output operates independently of the main output. It is enabled or disabled from the front panel by pressing the OUTPUT ENABLE Aux button. When the Aux output is enabled, the OUTPUT ENABLE Aux button is illuminated.
Introduction Analog Programming (APG) Connector J1 The APG connector is an 18-pin connector. See Figure 4-1. The APG connector provides access to the following functions: • • Sense control Analog programming and monitoring.

Introduction Making Control Connections CAUTION: Equipment damage Before making connections from external circuits to the Analog Programming Connector, turn the front panel power switch to Off and wait until the front panel displays are not illuminated. CAUTION: Equipment damage Program/monitor signal and return are internally connected to the power supply negative output (-S). Do not attempt to bias these away from that potential. To connect the output wires to the APG and DC output connector: 1.
Analog Programming (APG) and Isolated Analog Programming (ISOL) Wiring WARNING: Shock hazard There is a potential shock hazard at the output when using a power supply with a rated output greater than 60 V. Use load wiring with a minimum insulation rating equivalent to the maximum output voltage of the power supply. For example, select TEW, 105 °C, 600 V wiring for use with a 600 V, 1.4 A power supply. For most connectors and jumpers, use any suitable wire such as 20 to 26 AWG stranded wire.

Remote Operation Complete the Setup To complete the setup: ◆ Configure the XG to use the USB remote interface and set up the terminal that will be used on the connected PC. See “Selecting the Appropriate Communication Port” on page 5–20 and “Terminal Configuration” on page 5–17 for more details.
Hardware and Connection Setup Ethernet (ENET) or GPIB Connector (Optional) The power supply can be programmed from a remote terminal using a General Purpose Interface Bus (GPIB interface) or Ethernet (ENET). If you have a GPIB or ENET card, see the XG 850 Watt GPIB and Ethernet Interface Option Operating Manual (Part number M370078-06). The GPIB interface is an 8-bit parallel data bus having a host of bus commands for synchronization and up to one megabyte data transfer rate.
Remote Operation Multiple Power Supply Setup Master Setup: ◆ Configure the master XG by selecting the communication interface you wish to use to communication with the Master and follow the setup instruction in this chapter. Important: If either RS-232 or RS-485 are used for communication with the master, the data rate must be configured for 9600 bps to properly communicate with the slave units. Slave Setup: 1. Turn the 9-position mode control to PGM. rE is displayed in the output voltage display. 2.
Terminal Configuration Terminal Configuration The terminal program allows serial communication with the power supply. To use a terminal program, set it up using the parameters from the following sections. If you wish to use HyperTerminal, see “HyperTerminal” on page 5–17 for instructions setting it up.

Turn the 9-position mode control to PGM. rE is displayed in the output voltage display. 2. Turn the rotary Adjust/Enter control to select one of the communication ports: 232, 485, gPIb, USb, LAn.
Terminal Configuration Multichannel Address Setting The power supply multichannel address can be set to any address between 1 to 30. All units that are connected together via the RS-232 or RS-485 connector must have a unique multichannel address. To set the address: 1. Select the appropriate communication port as described “Selecting the Appropriate Communication Port” on page 5–20.
Remote Operation Remote Interface Addressing All commands must be issued with a multichannel address or the device must be selected using the: *adr or :SYST[]:COMM[:MCH]:ADDR commands. Once a device is selected all commands sent without a multichannel address will be handled by the selected device. The use of multichannel addresses supersedes the selected device as the destination for a message. For more details on how multichannel addresses affect responses, see Table 5-8.
Terminal Configuration Multichannel Commands Explained The use of multichannel addressing allows you to send messages to one device, more than one device or to all devices. Any of the remote interface types can be used to send a multichannel command through the device that is physically connected to the PC to all the devices, provided that all other devices are connected to via the RS-485 bus.
Remote Operation Multichannel commands are particularly useful for configuring groups of devices that require identical configurations. The SCPI Commands for these instructions are: [:] [,[ ]][,[ ]][,...]: For example: sour 1, 2, 3, 7:volt 4.
Terminal Configuration Status Reporting in SCPI The status reporting implemented in the XG is primarily dictated by the SCPI standard. This section provides a high level review of the standard status reporting required by SCPI and then covers the XG specific reporting that is implemented within the SCPI status reporting framework. Figure 5-16 is taken from the SCPI 99 standard and shows the minimum status reporting requirements for a SCPI compliant device.

Status Registers Model from IEEE 488.2 Status Registers Model from IEEE 488.2 The IEEE 488.2 registers shown in the bottom rectangle of Figure 5-16 follow the IEEE 488.2 model for status registers. The IEEE 488.2 register only has enable registers for masking the summary bits. Figure 5-17 shows the details on the relationship between the mask/enable registers and the summary bits. Sections describing the bits for both registers will follow Figure 5-17.
Remote Operation Status Byte The Status byte register contains the STB and RQS (MSS) messages as defined in 488.1. You can read the status byte register using a 488.1 serial poll or the 488.2 *STB? common command. The *STB? query causes the device to send the contents of the Status Byte Register and the Master Summary Status (MSS) summary message. The *STB? query does not alter the status byte, MSS, or RQS.
Status Byte Message Available (MAV) This bit is TRUE whenever the power supply is ready to accept a request by the Digital Programming Interface to output data bytes. This message is FALSE when the output queue is empty. Standard Event Status Summary (ESB) This bit is TRUE when a bit is set in the Standard Event Status Register.
Remote Operation Operation Status Register Summary (OSR) This bit is TRUE when a bit in the Operation Event Status Register is set and its corresponding bit in the Operation Status Enable Register is set. Service Request Enable Register The Service Request Enable Register allows you to select the reasons for the power supply to issue a service request. The Service Request Enable Register allows you to select which summary messages in the Status Byte Register may cause service requests.
Status Byte Standard Event Status Register (SESR) The standard event status register sets bits for specific events during power supply operation. All bits in the standard event status registers are set through the error event queue. The register is defined by IEEE 488.2 register and is controlled using 488.2 common commands: *ESE, *ESE?, and *ESR? as well as SCPI aliases for multichannel use.

See “Command Error List” on page B–3 for a list of possible error codes and descriptions.
Remote Operation Standard SCPI Register Structure All registers except the SERS and Status registers will have the following structure which control how they report status information. In all subsequent figures that have SCPI registers, this structure will be condensed down into a single block to simplify the figures. The simplified block will show a 16-bit register and the summary bit. See Figure 5-19 for details on the structure used for each standard SCPI register.
OPERation Status Register OPERation Status Register The operation status register is a standard SCPI, 16-bit register which contains information about conditions which are part of the power supply's normal operation. The Operation Status data structure has the operation status register and two sub-registers to represent shutdown and protection shutdown. Each of the sub-registers is summarized in a summary bit.

Remote Operation SCPI Error/Event Queue The error/event queue contains items that include a numerical and textual description of the error or event. Querying for the full queue item (for example, with SYSTem:ERRor[:NEXT]?) will return a response with the following syntax: , ";" The is a unique integer in the range [-32768, 32767]. All positive numbers are instrument-dependent.
SCPI Error/Event Queue Examples: SYST:ERR? SYST:ERR:EVENT? Responses might be: -102, "syntax error;” 0, "No Error;" Querying For the Error Code Only It is possible to query for only the error code. When querying the error code only the response will be the numeric error code only, no additional description will be given. The error queried will be removed from the queue.
Remote Operation Reset Command The Reset command performs a device reset. The Reset command is the third level of reset in a three level reset strategy, set out in IEEE 488.2 (see IEEE 488.2 standard, section 17.1.2). The Reset command shall do the following: 1. Set the device-specific functions to a known state that is independent of the past-use history of the device. See Table 3-9, “Power Supply Default Settings” on page 3–39 for details. 2. Force the device into the OCIS state, (see IEEE 488.
SCPI Error/Event Queue Clear All Status Registers Clear Status Command Clears all Event Registers, including the Status Byte, the Standard Event Status and the Error Queue.
Remote Operation SCPI Preset Status Configures the status data structures to ensure that certain events are reported at a higher level through the status-reporting mechanism. These events are summarized in the mandatory structures, the Operation Status Register and Questionable Status Register. The PRESet command affects only the enable registers and the transition filter registers of the status data structures. PRESet does not clear any of the event registers or any item from the error/event queue.
SCPI Error/Event Queue Command Line Help System The Help system is made up of a series of commands that can be used to get help on all available commands and details on their syntax. The Help commands are: [:]SYSTem[]:HELP[:HEADers]? [:]SYSTem[]:HELP:SYNTax?'' [:]SYSTem[]:HELP:LEGacy? Querying Help for all Command Headers The [:]SYSTem[]:HELP[:HEADers]? query shall return all SCPI commands and queries and IEEE 488.

SCPI Error/Event Queue Querying Help for Legacy Command Headers The [:]SYSTem[]:HELP:LEgacy? query is essentially the same as the [:]SYSTem[]:HELP[:HEADers]? command, but it lists legacy Xantrex commands. If executed it returns all Xantrex legacy commands and queries implemented. The response shall be on a page by page basis. No single line will be longer than 80 characters and each page will be 23 lines long.
Remote Operation Querying Help for Command Syntax The SYSTem[]:HELP:SYNTax? query causes the device to return a string containing the syntax specification of the command associated with the , a description of the command function and any aliases to the command. Each line of the response is tabbed to the right for readability. Any that is not a valid command header being recognized by the device, shall cause the device to return a null string (""). E.g.

Remote Operation Locking and Unlocking the Front Panel Locking out the front panel will prevent any of the buttons from functioning. All the buttons and knobs on the front panel will display the LOCL Loc message to be display on the Current and Voltage displays if pressed or rotated. This mode prevents any changes to the unit from the front panel. See the following procedure to lock and unlock the front panel.
Locking and Unlocking the Front Panel Setting Dwell Time The dwell time is the amount of time that is delayed between each command during the execution of an Auto Sequence program. The dwell time can be from 0 to 180 seconds and can be changed during the program execution. The dwell time has a minimum step size of 1 second. Command: [:]PROGram[][:STEP]:DWELl {?| } Where: is an integer value from 0 to 180.
Remote Operation :PROG:DWEL 0 :PROG:STOP This program will send a 12 V square wave with 120 seconds 50% duty cycle. When the program is finished, the dwell time is restored to 0 seconds. Saving an Auto Sequence Program to File: The following procedure indicates how to save an Auto Sequence program to a text file on the attached PC. To save an Auto Sequence Program to a file: 1. Start the text capture by selecting Transfer>Capture Text … from the Hyper Terminal program. 2.
Locking and Unlocking the Front Panel Another benefit to the readback command is it allows the auto sequence program to be captured and stored on the client side for reloading when the program is to persist beyond power cycles. Command: [:]PROGram[]:READback? For Example: :PROG:START *CLS :VOLT 5.4 :CURR 0.25 *IDN? :PROG:STOP :PROG:READ? Response: *CLS :VOLT 5.4 :CURR 0.
Remote Operation 4. From the Hyper Terminal (or any other terminal program) select the Transfer>Send Text File… 5. Navigate to and select the text file that was previously stored. Click the Open button. 6. Execute the program recording stop command: :PROG:STOP 7. Execute the readback command to verify the entire program was transferred correctly: PROG:READ? 8. Set the data rate back to the original speed. 9.
Locking and Unlocking the Front Panel :PROG:STAT RUN The output after the last command might be as follows: Xantrex, XG 150-5.6, SN# E00123456, 1.00 Build 10, 21/ 11/2005 Xantrex, XG 150-5.6, SN# E00123456, 1.00 Build 10, 21/ 11/2005 Important: Execution of the program may be terminated at any time by pressing the Esc key in the MS Windows Hyper Terminal window. The power supply can be controlled during program execution.
Remote Operation :PROG:REP 2 :PROG:STAT RUN The output after the last command might be as follows: Xantrex, XG 150-5.6, SN# E00123456, 1.00 Build 10, 21/ 11/2005 Xantrex, XG 150-5.6, SN# E00123456, 1.00 Build 10, 21/ 11/2005 Xantrex, XG 150-5.6, SN# E00123456, 1.00 Build 10, 21/ 11/2005 Xantrex, XG 150-5.6, SN# E00123456, 1.
Configure Other Protection Mechanisms Configure Other Protection Mechanisms Foldback Protection Foldback protection causes the output of the power supply to shut down if the selected regulation mode is entered and the configured delay time expires. A delay time may be specified as well. The only way to clear foldback is by pressing the rotary Adjust/Enter control for 3 seconds and executing the Clear command.
Remote Operation Over Temperature Protection The over temperature protection (OTP) is the alarm that protects the unit in case of ventilation blockage, fan failure, or some other event that cause the unit to overheat. The OTP can be masked to disable it. To mask an alarm, see “Alarm Masking” on page 3–21 which maps out the bit position for each of the flags. The alarm masking command can be entered using the SCPI command.
Configure Other Protection Mechanisms Save and Recall The save and recall of user settings can be done using commands as well as at the front panel. Executing the save and recall commands will have the same outcome as following the procedure outlined in “Saving User Setting Memory Locations” on page 3–35 and “Recalling User Setting Memory Locations” on page 3–36.
Remote Operation Set Remote Programming Interface The remote source can be select using the following SCPI commands. These commands are equivalent to the procedure on “Voltage-Controlled Voltage APG Setup” on page 4–10 and “Voltage-Controlled Current APG Setup” on page 4–12. Commands: [:]SYSTem[]:REMote:SOURce[:VOLTage] {?|LOCal|AVOLtage|ARESistive} [:]SYSTem[]:REMote:SOURce:CURRent {?|LOCal|AVOLtage|ARESistive} Where: LOCal indicates the value is controlled by the set point.
Configure Other Protection Mechanisms Protection Mask (Enable Alarms) The protection mask allows for the different alarms to be masked, completely disabling them. This means that the SCPI status and operations registers will not detect the alarms. You will have no way of knowing the current operation state of the alarm. The protection mask is a feature that is only accessible using the SCPI command noted below.

6 Calibration and Troubleshooting Chapter 6, Calibration and Troubleshooting, contains information and procedures for calibrating and troubleshooting the power supply.
Calibration and Troubleshooting Introduction The calibration of the power supply is software dependent, and there are no potentiometers to adjust. Calibration is performed via SCPI commands.
Calibration and Troubleshooting Main Voltage and Current Calibration Principle Understanding the Problem Figure 6-1 illustrates two sources of analog programming error: gain error and offset error. Gain error is the departure from the ideal slope of the measured versus programmed line. Offset error is the magnitude of the measured value when the programmed value is zero.
Calibration and Troubleshooting Step 1: Gain Calibration Figure 6-2 Calibration: Step 1 Gain Calibration Adjust the gain so that the real line and ideal line intersect at a programmed value of 90%. Step 2: Offset Calibration Figure 6-3 Calibration: Step 2 Offset Calibration Adjust the offset so that the real and ideal lines intersect at a programmed value of 10%.
Calibration and Troubleshooting Step 3: Recalibrate Gain Figure 6-4 Calibration: Step 3 Recalibrate Gain Repeat Step 1 for best results.
Calibration and Troubleshooting Calibrating the Output Voltage Gain calibration of the power supply has the greatest affect on the accuracy in the high voltage range. Offset calibration has the greatest affect on accuracy of the power supply at low voltages. The same calibration command is used for the gain and offset calibrations. The type of calibration is determined internally by the XG depending on if the set point is above 10% of the maximum output voltage value or not.
Calibration and Troubleshooting After performing offset calibration, Xantrex recommends that you repeat gain calibration. Important: For best results, both calibrations may be repeated several times. The SCPI Command (s) for these instructions are: [:]CALibration[]:OUTPut{:VOLTage]{} Calibrating the Output Current Gain Calibration To perform gain calibration: 1. Disconnect the power supply from the load. 2.
Calibration and Troubleshooting Offset Calibration Offset calibration of the power supply provides the best accuracy in lowrange current. To perform offset calibration: 1. After performing gain calibration, set the current to 10% from the nominal. 2. Read the current value on the ammeter display. 3. Type SCPI command with the current value as parameter "data". For example, you would type :CAL:OUTP:CURR 0.50 if you had an XG 150-5.6 calibrating with the current set point set to 0.
Calibration and Troubleshooting Over Voltage Protection Calibration Important: The Voltage Calibration must be done before performing this procedure. If this is not done the OVP calibration will be inaccurate. To calibrate the over voltage protection: 1. Turn on the power supply. 2. Select the VAP mode to be Off. 3. Set the voltage set point to be 90% of the model voltage and the current to be 10% of the model current. 4. Turn on the main power output. 5.
Calibration and Troubleshooting Non-isolated Analog Programming Calibration Prior to this, the main output must be calibrated first. Important: In calibration commands, when + or – keys are expected, any other key will exit from the calibration mode. Non-isolated Voltage Monitoring Calibration Important: For maximum accuracy at a specific APG level. Follow the calibration procedure again but use the intended operating voltage level in steps 3 and 8. To calibrate the non-isolated voltage monitoring: 1.
Calibration and Troubleshooting Non-isolated Current Monitoring Calibration Important: For maximum accuracy at a specific APG level.

Calibration and Troubleshooting Non-isolated Resistive Programming of Voltage Calibration Important: For maximum accuracy at a specific APG level. Follow the calibration procedure again but use the intended operating resistance level in steps 2 and 3. To calibrate the non-isolated resistive programming of voltage: 1. Disconnect the load and connect the voltmeter to the output. 2. Connect the 4.000kΩ resistor to the non-isolated connector, resistive programming of voltage, and voltage programming (J1.
Calibration and Troubleshooting Non-isolated Voltage Programming of Current Calibration Important: For maximum accuracy at a specific APG level. Follow the calibration procedure again but use the intended operating voltage level in steps 3 and 4. To calibrate the non-isolated voltage programming of current: 1. Short the main output with a shunt. Connect a multimeter to measure the voltage across the shunt. 2. Connect the input voltage source to the non-isolated connector, current programming (J1.10 - J1.
Calibration and Troubleshooting Non-isolated Resistive Programming of Current Calibration Important: For maximum accuracy at a specific APG level. Follow the calibration procedure again but use the intended operating resistance level in steps 2 and 3. To calibrate the non-isolated resistive programming of current: 1. Short the main output with a shunt. Connect a multimeter to measure the voltage across the shunt. 2. Connect the 4.
Calibration and Troubleshooting Calibration Procedure for Isolated Modes The main output and the non-isolated mode must be calibrated first. Isolated Voltage Monitoring Calibration Important: For maximum accuracy at a specific APG level. Follow the calibration procedure again but use the intended operating voltage level in steps 3 and 8. To calibrate the isolated voltage monitoring: 1. Disconnect the load and connect the voltmeter to the output. 2.
Calibration and Troubleshooting Isolated Current Monitoring Calibration Important: For maximum accuracy at a specific APG level. Follow the calibration procedure again but use the intended operating voltage level in steps 3 and 8. To calibrate the isolated current monitoring: 1. Short the main output with a shunt. Connect a multimeter to measure the voltage across the shunt. 2. Connect the voltmeter to the Isolated monitoring output lines (J3.10 and J3.6). 3. Set the current APG level to 4 V.
Calibration and Troubleshooting Isolated Voltage Programming of Voltage Calibration Important: For maximum accuracy at a specific APG level. Follow the calibration procedure again but use the intended operating voltage level in step 3. To calibrate the isolated voltage programming of voltage: 1. Disconnect the load and connect the voltmeter to the output. 2. Connect the input voltage source to the Isolated connector (J3.3 and J3.6). 3. Set the Voltage APG level to 4 V.
Calibration and Troubleshooting Isolated Resistive Programming of Voltage Calibration Important: For maximum accuracy at a specific APG level. Follow the calibration procedure again but use the intended operating resistance level in step 3. To calibrate the isolated resistive programming of voltage: 1. Disconnect the load and connect the voltmeter to the output. 2. Connect the 4.000 kΩ resistor to the isolated connector. One terminal to resistive programming of voltage (J3.
Calibration and Troubleshooting Isolated Voltage Programming of Current Calibration Important:: For maximum accuracy at a specific APG level. Follow the calibration procedure again but use the intended operating voltage level in step 3. To calibrate the isolated voltage programming of current: 1. Short the main output with a shunt. Connect a multimeter to measure the voltage across the shunt. 2. Connect the input voltage source to the Isolated connector (J3.4 J3.6). 3. Set the Current APG level to 4 V.
Calibration and Troubleshooting Isolated Resistive Programming of Current Calibration To calibrate the isolated resistive programming of current: 1. Short the main output with a shunt. Connect a multimeter to measure the voltage across the shunt. 2. Connect the 4.000 kΩ resistor to the isolated connector. One terminal to resistive programming of current (J3.7), and voltage programming of current (J3.3), and the other to common (J3.2). 3. Set the Resistive APG level to 4 kΩ.
Calibration and Troubleshooting Calibrating the Input Voltage APG Signal The input voltage APG calibration is necessary to ensure accurate measurements when using the :MEAS:APR? and :MEAS:APR:ISOL? SCPI command queries to monitor the APG input signal. Gain Calibration To calibrate the VAP APG input gain: 1. Connect a voltmeter and a DC voltage source to the non-isolated voltage APG input lines (J1.9 and J1.7). 2. Turn the power supply On. 3. Set the Voltage APG level to 4 V.
Calibration and Troubleshooting 4. Type SCPI input Voltage calibration command with voltage noted in step 3 as the parameter “data”. For example, you would type :CAL:INP:ANAL:CURR 0.43 if you read 0.43 volts from the voltmeter. After performing offset calibration, it is highly recommended that you repeat gain calibration.
Calibration and Troubleshooting Offset Calibration Offset calibration of the power supply provides the best accuracy in lowrange input current. To perform offset calibration: 1. Set the voltage source attached to the non-isolated current APG input to 10% of the nominal current level, in this case 0.400 V. 2. Turn the output power on. 3. Read the input voltage value from the voltmeter connected in step 2 of the gain calibration. 4.
Calibration and Troubleshooting Storing and Loading Calibration Parameters Xantrex recommends that you save all the calibration parameters in a text file so they can be reloaded in the event of a flash failure or a mistake in calibration.
Calibration and Troubleshooting By saving and reloading the calibration parameters using these commands, you can calibrate the XG for maximum accuracy for a specific load and then switch loads and load a calibration set that is accurate at maximum accuracy for the new load. Restore Factory Calibration Important: Factory calibration is not the same as the shipped calibration. Using this command will likely necessitate recalibrating all controls.
Calibration and Troubleshooting User Diagnostics If your power supply is not performing as described in this Manual, read through the procedures and checks in this chapter before calling your service technician. These procedures are limited to operator level functions only. They do not require cover-off servicing of the unit. Emergency Shutdown In an emergency, carry out these steps: 1. Shut the power supply OFF immediately. 2. Disconnect the mains supply. 3. Disconnect the power supply from the load.
Calibration and Troubleshooting Troubleshooting for Operators Refer to Table 6-1 to ensure that the power supply is configured and connected for normal operation. If you require any further troubleshooting assistance, call your service technician. See “Contact Information” on page iii. Table 6-1 Troubleshooting Symptom Check Further Checks and Corrections The power supply is not operating. FLA FAIL is displayed. Flash memory check sum error. Do a reset. See page 3–39.
A SCPI Command Reference Appendix A, SCPI Command Reference, provides a summary of the Standard Commands for Programmable Instruments (SCPI) that are supported by the XG 850 Watt Series Programmable DC Power Supply.
SCPI Command Reference SCPI Conformance Information Codes and Standards This power supply conforms to the following international standards: • • • • IEEE Std. 488.2-1992, “IEEE Standard Codes, Formats, Protocols, and Common Commands For Use With IEEE Std. 488.1-1987” IEEE Std. 488.1-1987 “IEEE Standard Digital Interface for Programmable Instrumentation” TIA/EIA-232F Standard Commands for Programmable Instruments (SCPI) Version 1999.0 IEEE 488.2 Requirements GPIB control implements all IEEE 488.
SCPI Conformance Information SCPI Command Hierarchy SCPI is an ASCII-based command language designed for use in test and measurement equipment. The command structure is organized around common roots, or nodes, which are the building blocks of SCPI subsystems. An example of a common root is CALibration, and some of the commands that reside in the CALibration subsystem are: [:]CALibration [:OUTPut] [:VOLTage] [:DATA] :CURRent [:DATA] CALibration is the root keyword of the command.
SCPI Command Reference Using SCPI Commands This Manual shows SCPI commands in the following format: CALibration:CURRent:LEVel {|MIN|MAX} The command is expressed as a mixture of upper- and lowercase letters. The uppercase letters suggest how the command can be abbreviated into a short form. SCPI commands can be sent in long or short forms. The short form is better for data entry. The long form is better for readability.
SCPI Conformance Information The following punctuation is not sent with the command string: • • • • Braces ({ }), or curly brackets, identify a selection of choices. Choose one of the enclosed values. Vertical bars, or pipes, ( | ) can be read as “or” and is used to separate the choices found within the braces. Angle brackets ( < > ) identify where specific values must be entered for a parameter. For example, in the example at the top of the page, the parameter appears in the command string.
SCPI Command Reference Terminating Characters Every command string must end with a terminating character. It is also acceptable to use a followed by a . Terminating a command string always resets the SCPI command path to the root level. Common Commands The IEEE-488.2 standard includes a set of common commands for functions such as reset and self-test.
SCPI Conformance Information Parameter Types Several different data types are defined for use in program messages and response messages. Boolean Parameters Boolean parameters are single binary conditions such as 1 and 0, or ON and OFF. The following is an example of a command that uses Boolean parameters: SYST:COMM:GPIB:PONS {ON|OFF|1|0} Discrete Parameters Discrete parameters are used when program settings have a limited number of values.
SCPI Command Reference SPCI Command Tree The SCPI commands are organized into a tree structure. To illustrate the tree structure, the following tree has been provided. Each level of indentation presents a branch. The command to execute can then be found by following the tree from the root or farthest left node all the way down to the leaf node.

B Error Messages Appendix B, Error Messages, provides information on the error messages which may appear. Errors are placed in a queue as they are detected.
Error Messages Error Messages Errors are placed in a queue as they are detected. The queue works on a first in, first out (FIFO) basis. If the queue overflows, the last error in the queue is replaced with error –350, “Queue Overflow”. When all errors have been read from the queue, further error queries return 0, “No error”. The error queue is cleared when any of the following occur (IEEE 488.2, section 11.4.3.
Error Messages Command Error List An error in the range [-199, -100] indicates that an IEEE 488.2 syntax error has been detected by the instrument’s parser. The occurrence of any error in this class causes the command error bit (bit 5) in the Event Status Register to be set.
Error Messages Execution Error List An error in the range [-299, -200] indicates that an error has been detected by the instrument’s execution control block. The occurrence of any error in the class causes the execution error bit (bit 4) in the Event Status Register to be set. Execution errors are reported by the device after rounding and expression evaluation operations have taken place.
Error Messages Table B-2 Execution Error List Error Code Error Message Description -222 Data out of range Indicates that a legal program data element was parsed but could not be executed because the interpreted value was outside the legal range as defined by the device (see IEEE 488.2, 11.5.1.1.5) -224 Illegal parameter value Used where the exact value, from a list of possible values, was expected. -291 Out of memory Used when the Autosequence programming buffer is full.
Query Error List An error number in the range [-499, -400] indicates that the output queue control of the instrument has detected a problem with the message exchange protocol described in IEEE 488.2, chapter 6. The occurrence of any error in this class causes the query error bit (bit 2) in the Event Status Register to be set.
