CHAPTER 3: INSTALLATION 3.1 General This chapter contains instructions for initial inspection, preparation for use and repackaging for shipment. Connection to PC, setting the communication port and linking Z+ power supplies are described in Chapter 7. NOTE: Z+ power supplies generate magnetic fields which might affect the operation of other instruments. If your equipment is susceptible to magnetic fields, do not position it adjacent to the power supply. 3.
3.5 Location, Mounting and Cooling This power supply is fan cooled. The air intake is at the front panel and the exhaust is at the rear panel. Upon installation allow cooling air to reach the front panel ventilation inlets. Allow minimum 10cm (4”) of unrestricted air space at the front and the rear of the unit. The power supply should be used in an area that the ambient temperature does not exceed +50°C.
3.7.2 AC Input Cord Refer to section 1.3.4 for details of the AC input cords recommended. WARNING: The AC input cord plug is the disconnect device of the power supply. The plug must be readily identifiable and accessible to the user. The AC input cord must be no longer than 3m. WARNUNG: Das Netzstromkabel dient zur Trennung des Netzgerätes vom Netzstrom. Der Stecker muss für den Benutzer leicht erkennbar und jederzeit zugänglich sein. Das Netzstromkabel darf nicht länger sein als drei Meter. 3.
3.8.3 Constant Voltage Check 1. Turn on the output by pressing OUTPUT button so the OUTPUT LED illuminates. 2. Observe the power supply Voltage display and rotate the Voltage encoder. Ensure that the output voltage varies while the Voltage encoder is rotated. The minimum control range is from zero to the maximum rated output for the power supply model. Compare the DVM reading with the front panel Voltage display to verify the accuracy of the Voltage display. Ensure that the front panel CV LED illuminates.
3.8.7 Foldback Check WARNING: There is a potential shock hazard when checking a power supply with output voltage greater than 42.4V. Observe proper safety procedures during the checking. WARNUNG: Beim Einsatz eines Netzteils mit einer Nenn-Ausgangsspannung von mehr als 42.4V besteht Stromschlaggefahr. Beachten Sie bei der Überprügung die entsprechenden Sicherheitsvorkehrungen. Refer to Section 5.3.4 for explanation of the FOLD function prior to performing the procedure below. 1. 2. 3. 4.
3.9.2 Current Carrying Capacity Two factors must be considered when selecting the wire size: 1. Wires should be at least heavy enough not to overheat while carrying the power supply load current at the rated load, or the current that would flow in the event the load wires were shorted, whichever is greater. 2. Wire size should be selected to enable voltage drop per lead to be less than 1.0V at the rated current.
3.9.3 Wire Termination The wires should be properly terminated with terminals securely attached. DO NOT use non terminated wires for load connection at the power supply. CAUTION: When local sensing, a short from +LS or +S to -V or -S or -LS, will cause damage to the power supply. Reversing the sense wires might cause damage to the power supply in local and remote sensing. (Do not connect -S to +V or +S to -V.) 3.9.
CAUTION: Ensure that the load wiring mounting hardware does not short the output terminals. Heavy connecting cables must have some form of strain relief to prevent loosening the connections or bending the bus-bars. 10V to 100V Models Refer to Fig.3-4 for connection of the load wires to the power supply bus-bars and to Fig.3-5 for mounting the bus-bars shield to the chassis. Fig. 3-4: Load wires connection, 10V to 100V models.
WARNUNG: Beim Einsatz eines Netzteils mit einer Nenn-Ausgangsspannung von mehr als 42.4V besteht Stromschlaggefahr. Schalten Sie die Stromversorgung mit einer Ausgangsspannung oberhalb 42.4VDC nicht auf EIN, ohne die vorhige Montierung eines Schutzes für die Ausgangssammelschiene bzw. Ausgangsbuchse. Stellen Sie sicher, dass der Schutz der Ausgangssammelschiene oder des Ausgangs aufgesetzt und angemessen montiert ist und dass der Schutz der Sammelschiene, mittels zweier SEMS-Schrauben, wie in Abb. 3.
3.9.9 Connecting Multiple Loads, Radial Distribution Method Fig.3-8 shows multiple loads connected to one supply. Each load should be connected to the power supply’s output terminals using separate pairs of wires. It is recommended that each pair of wires will be as short as possible and twisted or shielded to minimize noise pick-up and radiation. The sense wires should be connected to the power supply output terminals or to the load with the most critical load regulation requirement.
3.9.11 Grounding Outputs Either the positive or negative output terminals can be grounded. To avoid noise problems caused by common-mode current flowing from the load to ground, it is recommended to ground the output terminal as close as possible to the power supply chassis ground. Always use two wires to connect the load to the power supply regardless of how the system is grounded. WARNING: Models up to 100VDC Rated Output shall not float outputs more than +/-100VDC above/below chassis ground.
3.10.2 Local Sensing The power supply is shipped with the rear panel J2 sense connector wired for local sensing of the output voltage. Refer to Table 3-4 for J2 terminals assignment. With local sensing, the output voltage regulation is made at the output terminals. This method does not compensate for voltage drop on the load wires, therefore it is recommended only for low load current applications or where the load regulation is less critical. Fig.
CAUTION: When using shielded sense wires, ground the shield in one place only. The location can be the power supply chassis or one of the output terminals. Use remote sense where the load regulation at the load end is critical. In remote sense, the power supply will compensate for voltage drop on the load wires. Refer to the specifications for the maximum voltage drop on load wires. The voltage drop is subtracted from the total voltage available at the output.
CHAPTER 4: FRONT/REAR PANEL CONTROLS AND CONNECTORS 4.1 Introduction The Z+ Power Supply series has a full set of controls, indicators and connectors that allow the user to set up and operate the unit. Before starting to operate the unit, please read the following sections for an explanation of the functions, controls and connector terminals. - Section 4.2: Front Panel Display and Controls. - Section 4.3: Rear Panel Controls and Connectors. 4.

CHAPTER 5: LOCAL OPERATION 5.1 Introduction This Chapter describes the operating modes that do not require programming and monitoring the power supply via its serial communication ports. USB or RS232/RS485 or by remote analog signals. Ensure that the REM LED on the front panel is Off, (indicating Local mode). If the REM LED is On, press the front panel REM button to change the operating mode to local. - For information regarding remote analog programming refer to Chapter 6.
5.2.3 Automatic Crossover When the power supply operates in Constant Voltage mode, while the load current is increased to greater than the current limit setting, the power supply will automatically switch to Constant Current mode. If the load is decreased to less than the current limit setting, the power supply will automatically switch back to Constant Voltage mode. 5.2.4 Output On/Off Control The Output On/Off enables or disables the power supply output.
5.3 Alarms and Protective Functions 5.3.1 Introduction There are several conditions that cause alarm (RED LED blinks). All alarms affect the output. When an alarm occurs, the respective fault will appear on the display and the alarm LED illuminates. It is possible that more than one fault (alarm) may be triggered but only the first will be shown on the display. If the second fault is still active when the first fault is removed, then the second fault will be displayed.
5.3.2.2 Resetting the OVP Circuit To reset the OVP circuit after activation: 1. Reduce the power supply Output Voltage setting below the OVP set level. 2. Ensure that the load and the sense wiring is connected properly. 3. Four methods to reset the OVP circuit. • Press OUTPUT button. • AC recycle. • On/Off recycle by analog control (Interlock). • Send communication command to enable output. 5.3.
5.3.4.1 Setting the Foldback Protection The Foldback can be set when the power supply output is Enabled (On) or Disabled (Off ). 1. Press PROT button. PROT (GREEN) LED illuminates. The ”OUP” message appears on the Voltage display. 2. Rotate Voltage encoder until ”” message appears on Voltage display. 3. Press Voltage encoder. ”” message appears on Voltage Display, and on Current display shows ”” or ”” or ”” setting mode. 4.
5.4 Series Operation Power supplies of the same model can be connected in series to obtain increased output voltage. Split connection of the power supplies gives positive and negative output voltage. 5.4.1 Series Connection for Increased Output Voltage Two units are connected so that their outputs are summed. Set the current limit of each power supply to the maximum that the load can handle without damage.
5.4.3 Remote Programming in Series Operation Programming by external voltage: The analog programming circuits of this power supply are referenced to the negative Sense potential. Therefore, the circuits used to control each series connected unit must be separated and floated from each other. Refer to section 6.4 Using the SO function and PS_OK signal : The Shut Off and PS_OK circuits are referenced to the isolated interface common, IFC_COM (J3-7).
5.5 Parallel Operation 5.5.1 Introduction Up to six units of the same Voltage and Current rating can be connected in parallel to provide up to six times the output current capability. One of the units operates as a master and the remaining units are slaves. The slave units are analog programmed by the master unit. In remote digital operation, only the master unit can be programmed by the computer while the slave units may be connected to the computer for voltage, current and status readback only.
5.5.2.2 Slave Unit Set Up When Slave mode is selected the power supply enters Current programming mode via external Voltage. Voltage and Current programming setting values are set to 105% of range. During operation the slave units operate as a controlled current source following the master output current. It is recommended that the power system is designed so that each unit supplies up to 95% of its current rating. This helps reduce imbalance which may occur by cabling and connections voltage drop. 1. 2. 3.
Fig.5-5: Parallel operation with remote sensing CAUTION: Make sure that the connection between - Vo terminals is reliable to avoid disconnection during operation. Disconnection may cause damage to the power supply. NOTE: With local sensing it is important to minimize the wire length and resistance. Also the positive and negative wire resistance should be as close as possible to each other to achieve current balance between power supplies.
5.5.3 Advanced Parallel Operation In Advanced Parallel operation the master unit displays the total current of all units connected in Parallel. The slave units display ”ON SLUE”. The master and slave units operate in a Daisy-Chain connection configuration. For further details about Daisy-chain connection refer to section 5.6. In the Advanced Parallel mode, the total current is programmed and reported by the master unit. The Current display accuracy is 2%+/- 1 count.
5.6 Daisy-Chain Connection It is possible to configure a multiple power supply system to shut down all units when a fault condition occurs in one of the units. When the fault is removed, the system recovers according to a preset state: Safe start mode or Automatic restart. Set signal ”SO” to positive logic via Front panel (refer to section 5.7.1) . If a fault occurs in one of the units it’s ”PS_OK” signal will be set to low level and the display will indicate the fault.
5.7.1 External Shut Off Function SO signal serves as Output Shut Off . It is an optically isolated signal from the power supply output. Connection to the signal is made via pin J3-5 (Shut Off ) and pin J3-7 (IFC_COM). The SO pin accepts a 2.5V to 15V signal or Open-Short contact to disable or enable the power supply output. The SO function will be activated only when a transition from On to Off is detected after applying AC power to the unit.

5.7.4 Power Supply OK Signal PS_OK signal indicates fault condition in the power supply. It is a TTL signal output at J3-2, referenced to IFC_COM at J3-7 (Isolated Interface Common). When a fault condition occurs, PS_OK level is low, with maximum sink current of 1mA. When no fault condition occurs, PS_OK level is high with maximum source current of 2mA. All conditions when output status is disabled sets PS_OK to low level. The PS_OK signal at high level can be delayed via Front panel setting or software.

CHAPTER 9: STATUS, FAULT AND SRQ REGISTERS 9.1 General This section describes various status errors (faults) and SRQ register structures. The registers can be read or set via the RS232/485/USB commands. Refer to Fig.9-1 for the Status and Fault Registers Diagram. Fig.
9.2 Power Supply Status Structure Status and Fault Register shows the status register structure of the power supply. The Standard Event, Status Byte, and Service Request Enable registers and the Output Queue perform standard functions as defined in the IEEE 488.2 Standard Digital Interface for Programmable Instrumentation. The Operation Status and Questionable Status registers implement status functions specific to the power supply. 9.
9.3.2 Status Register The status register sets a bit when status changes (Refer to Table 9-2). The bit is cleared when the condition is removed.
9.6 Standard Event Status Group 9.6.1 Register Functions This group consists of an Event register and an Enable register that are programmed by COMMON commands. The Standard Event register latches events relating to interface communication status. It is a read-only register that is cleared when read. The Standard Event Enable register functions similarly to the Enable registers of the Operation and Questionable status groups. 9.6.
9.6.3 Status Byte Register This register summarizes the information from all other status groups as defined in the IEEE 488.2 Standard Digital Interface for Programmable Instrumentation standard. The register can be read either by a serial poll or by *STB?. Both methods return the same data, except for bit 6. Sending *STB? return MSS in bit 6, while polling returns RQS in bit 6. The *CLS command will clear the Status Byte.
9.6.5 Output Queue The Output Queue is a first-in, first-out (FIFO) data register that stores power supply-to-controller messages until the controller reads them. Whenever the queue holds one or more bytes, it sets the MAV bit (4) of the Status Byte register. If too many unread error messages are accumulated in the queue, a system error message is generated. The Output Queue is cleared at power On and by *CLS. 9.6.6 Error Messages System Error Messages are read back via the SYST:ERR? query.
Error Error Description Number Error Event 0 ”No Error” No Error Reported -100 ”Command Error” Unit Receives Command With Unspecified Error. -101 ”Invalid Character” A Character Was Received That Is Not: A-Z, A-Z, 0-9, ?, *, :, ;, Period, Space, CR, LF. -104 ”Data Type Error” IEEE Receives Command Parameter With Wrong Type Of Data. Example: Receives Letter Where Number Expected. -109 ”Missing Parameter” Valid Command Received But Not Enough Characters.
