1 Introduction This manual provides operating instructions for the Crompton Switchboard Integra series of Digital Metering Systems. Some versions of the Integra incorporate the metering transducer that provides the interface for the measurement of power supply parameters such as voltage, current, power, frequency etc. In other versions, the display and transducer are separate, interconnected units. The display allows the user to set up metering transducer parameters and to monitor the measurements.
1.1 Unit Characteristics 1.1.1 0240 The 0240 will display the following parameters: • System voltage (average of all phases) • System frequency (Hz) • Voltage line to neutral for each phase (4-wire systems only) • Voltage line to line for each phase (calculated in 4-wire) The 0240 has Set-up screens for potential transformer primary and secondary voltages. Default display 1.1.
1.1.
1.1.5 1540 The1540 is available either as a display unit operating in conjunction with a 15xx measurement transducer or as a self-contained unit incorporating a transducer. The unit can measure and display the following: Default display • System voltage (average of all phases) • System current (average of all phases) • System frequency (Hz) • Voltage line to neutral for each phase (4-wire systems only) • Voltage line to line for each phase (calculated in 4-wire) • Current in each line.
1.2 Maximum Power Products covered in this manual are limited to a maximum power of 360 MW. During set-up, primary voltage and current setting are checked and the unit will not accept entries that breach the 360 MW limit. This is covered in more detail in the sections that show primary voltage and current set-up. The Maximum Power restriction of 360 MW refer to 120% of nominal current and 120% of nominal voltage, i.e. 250 MW nominal system power. 1.
1.5 RS485 Serial Option 0240 0340 0440 0640 1000 1540 Option This option is available on two-part (separate transducer and display) units and on 1000 and self-contained 1540 units. This option uses an RS485 serial port with Modbus or JC NII protocol to provide a means of remotely monitoring and controlling the Integra unit. Both protocols are supplied in the same unit. Communications automatically configure according to the protocol that is recognized when the master sends a message.
2 Display Screens 2.1 Layout The screen is used in two main modes: display of measured values and parameter setup. In display mode, three measured values can be shown, one on each row. For each row, the LED indicators show the parameter being measured and the units. The >> button moves between display screens.
The second screen indicates the firmware installed in the display unit. This example states that the version is 0.008. The version on a particular unit will differ in line with ongoing development and improvements. After a short delay, the default Display screen will appear. Use the >> (Next) key to move from one screen to the next in the sequence. The sequence depends on the supply configuration (single phase 2 or 3 wire, 3 phase 3 or 4 wire). 2.

2.18 kWh and kVArh Display Range 0240 0340 0440 0640 1000 1540 The kWh and kVArh display range is limited to 9999999. If the unit is allowed to increment beyond this value the count will either wrap back to zero (if the 1560/1580 transducer is set to 7 digit mode) or continue to be updated in the 1560/1580 transducer but the display will change to seven bars. The value will continue to be available via the Modbus output. 2.
3.2 Number Entry Procedure When setting up the unit, many screens require the setting up of a number, usually on the middle row of digits. In particular, on entry to the setting up section, a password must be entered. The procedure is as follows: In general, press the (adjust) key to change something on the current screen. Pressing the >> (next) key normally leaves the current screen unchanged and brings up the next screen. The example below shows how the number 0000 can be changed to 1234.
Use the key to set the fourth digit to the required value. Press the >> key to confirm your selection. If the unit accepts your entry, the Confirmation screen will appear. If the unit does not accept your entry, e.g. an incorrect password, a rejection screen will appear, with dashes on the bottom line. Fourth digit The Confirmation screen shows the entered number on the bottom row with all decimal points showing. If the displayed number is correct, press the >> key to move to the next Set-up screen.
3.3 Access To access the Set-up screens, press the Password Introduction screen appears. and >> keys simultaneously for five seconds, until the Password protection can be enabled to prevent unauthorised access to Set-up screens. Password protection is not normally enabled when a product is shipped. The unit is protected if the password is set to any four digit number other than 0000. Setting a password of 0000 disables the password protection. 3.3.
Enter the four-digit password using the method described in Section 3.2 Number Entry Procedure. First digit On pressing >> to confirm the last digit, the Confirmation screen will appear, provided the password is correct. From the Password Confirmation screen, there is the option of changing the password, as described in Section 3.4 Changing the Password. To proceed to the first Set-up screen, press >>.
3.4 Changing the Password The option to change the password is only available from the Password Confirmation screen immediately after the user has entered the existing password, if applicable. Press to start changing the password. The password screen for the first digit will appear, with the old password on the bottom line. Password Confirmation Set up the new password on the bottom line, as described in Section 3.2 Number Entry Procedure.
3.5 Full Scale Current 0240 0340 0440 0640 1000 1540 This parameter is the value of nominal Full Scale Currents that will be displayed as the Line Currents. This screen enables the user to display the Line Currents inclusive of any transformer ratios. The values displayed represent the current in amps.
To set up the PT primary, proceed as follows: To accept the currently displayed value, press >>. The screen will move on to the next Set-up screen (Section 3.7 Potential Transformer Secondary Value). Press to change the PT Primary voltage. Initially all the digits of the present value will be flashing and the decimal point position will be illuminated. This is to indicate that initially the ‘multiplier’ must be selected. Press to set the decimal point position. Note that the x1000 indicator is on.
3.7 Potential Transformer Secondary Value 0240 0340 0440 0640 1000 1540 In Model 1000 and 1540 combined, the PT Secondary Value is factory set, as marked on the barrel. The PT Secondary Value is user programmable on the 1540 and Integra 1560 two part. This value must be set to the nominal full scale secondary voltage which will be obtained from the transformer when the potential transformer (PT) primary is supplied with the voltage defined in Section 3.6 Potential Transformer Primary Voltage.
Press >> to accept the displayed value. Depending on the model, this may take you out of the Set-up screens and back to the last selected Display screen. Press to return to the Decimal Point screen. The secondary value may only be set to values within the range defined by the factory voltage build option. These nominal rms input voltages are as shown in the relevant measurement transducer specification (see separate document for two-part products or Section 4.2.1 Inputs for combined products).
3.9 Resets 0240 0340 0440 0640 1000 1540 The following screens allow resetting of the Energy and Demand readings individually or altogether. Resetting the cumulative Energy (h) resets both Active and Reactive Energy.

Confirmation 3.10 Pulsed Output, Pulse Duration 0240 0340 0440 0640 1000 1540 Option This applies to the Relay Pulsed Output option only. Units with this option provide pulses to indicate power consumption (kWh). See Section 1.6 pulse output option. This screen allows the user to set the duration of the relay output pulse.
3.11 Pulse Rate 0240 0340 0440 0640 1000 1540 Option This applies to the Relay Pulsed Output option only. Units with this option provide pulses to indicate power consumption (kWh). This screen allows setting of the kWh pulse rate divisor. On a two part DIS 1540/Integra 1560, this screen will set the pulse rate for the kvarh pulse relay (where fitted) also. By default, the unit produces one pulse per kWh.
3.12 RS485 Baud Rate 0240 0340 0440 0640 1000 1540 Option Use this screen to set the Baud Rate of the RS485 Modbus/JC NII port. The values displayed are in kbaud. Where the transducer unit may be separate from the display unit, the transducer has two Modbus ports, at least one of which may be used for communicating with a display. The RS485 Baud Rate option only sets the Baud Rate for a port that is not communicating with a display unit.
3.13 RS485 Parity Selection 0240 0340 0440 0640 1000 1540 Option This screen allows setting of the parity and number of stop bits of the RS485 Modbus/JC II port. Where the transducer unit is separate from the display unit, the transducer has two Modbus ports, one of which may be used for communicating with a display. The RS485 Parity Selection option only sets the parity for a port that is not communicating with a display unit. The port characteristics for communication with a display are preset.
3.14 RS485 Modbus Address 0240 0340 0440 0640 1000 1540 Option This screen allows setting of the Modbus/JC NII device address for the instrument. Where the transducer unit is separate from the display unit, the transducer has two RS485 ports, one of which may be used for communicating with a display. The Address option only sets the address for a port that is not communicating with a display unit. The port characteristics for communication with a display are preset.
3.15 Analogue Output Set Up 0240 0340 0440 0640 1000 1540 Option This is an option on Models 1540 that have separate (1560 or 1580) transducers. 3.15.1 Introduction This applies to the analogue output option only, allowing the parameter to be selected, and the upper and lower limits adjusted, for either one or two channels. For each analogue output fitted, provision is made for five values to be user selected. These are: • A1r – Parameter, from Table 2.
3.15.2 Analogue Output Scaling Example In this example, the Integra has an output current range of 0 to 10mA and it is required that this output range represents a reading range of 95 to 135V. Example Output top 10mA 135V Reading top Analogue Output current from unit Reading Value represented by Output Output bottom 0mA 95V Reading bottom 3.15.2.1 Reading (A1r or A2r) The measured electrical parameter that the analogue output will represent.
3.15.2.6 Output Bottom (A1ob or A2ob) This is the value of output that will be reached when the measured electrical parameter is at the reading bottom value. Example: 0mA 3.15.2.7 Summary In the above example, the analogue output will be 0 mA when the average voltage is 95 volts, 5 mA at 115 volts and 10 mA at 135 volts. 3.15.3 Power Factor When analogue output current is used to represent power factor, it can indicate the power factor for an inductive or capacitive load on imported or exported power.
When setting up the analogue output for a power factor reading, the Reading Top value must be in one of the left-hand quadrants and the Reading Bottom value must be in one of the righthand quadrants. Hence, if the Reading Top value is set to –0.5, this will be a power factor of 0.5 for power exported to an inductive load (bottom left-hand quadrant). Conversely, the Reading Bottom value must be in one of the two right-hand quadrants. If the Reading Bottom value is set to –0.
In the example above, the unit has an analogue output range of 0 to 1 mA, all power is imported and the load is inductive. The 1 mA Output range covers a reading power factor range of 0.6, from 0.9 capacitive to 0.5 inductive. The capacitive overlap is provided in case of overcompensation of power factor. The Output to Reading correlation is as follows: Reading European Convention Output North American Convention Output 0.9 PF cap. 0 mA 1 mA 1 PF 0.167 mA 0.833 mA 0.9 PF ind. 0.333 mA 0.
In this example, the unit is set to represent the full range of inductive and capacitive loads on imported and exported power. The unit has an analogue output range of –1 to +1 mA. Both Reading Top and Reading Bottom are set to –1 power factor. 3.15.4 Phase Angle The Phase Angle analogue outputs are treated in a similar manner to Power Factor, with values specified in degrees. The following figure shows the relationship between phase angle in degrees and power factor.

3.15.7 Reading Top – A1rt or A2rt The top reading is limited to 120% of the nominal maximum value of the parameter. For example, a 230V nominal can be adjusted from 0 to 276V. The minimum is zero or –120% if the parameter is signed. This screen allows a negative value to be specified as the top reading. It will only be available if the parameter selected on the previous screen can be negative. For these parameters, the +/- column of Table 2 has a tick (✓).
Press >> to accept the displayed Reading Top value, The next Set-up screen will appear. Press to return to the Edit screen. Confirmation 3.15.8 Reading Bottom - A1rb or A2rb Use these screens to specify the minimum or most negative value for the Reading Bottom value. The method of setting the Reading Bottom screens is the same as for setting the Reading Top screens, as described in Section 3.15.7. The Reading Bottom screens show A1rb (or A2rb for the Analogue output 2) on the top line. 3.15.

5 Basis of measurement and calculations Reactive and Apparent Power Active powers are calculated directly by multiplication of voltage and current. Reactive powers are calculated using frequency corrected quarter phase time delay method. Apparent power is calculated as the square root of sum of squares of active and reactive powers. For 4 wire products, overall powers are the sum of the per phase powers. For 3 phase 3 wire products, the "two wattmeter" method is used for overall powers.
Time Integration Periods can be set to 8, 15, 20 or 30 minutes. Note: During the initial period when the "sliding window" does not yet contain a full set of readings (i.e. the elapsed time since the demands were last reset or the elapsed time since Integra was switched on is less than the selected demand period) then maximum demands may not be true due to the absence of immediate historical data.
6 Serial Communications 6.1. RS485 Port – Modbus or JC N2 0240 0340 0440 0640 1000 1540 Option INTEGRA 1000 and 1540 offer the option of an RS485 communication port for direct connection to SCADA systems. This port can be used for either an RS485 Modbus RTU slave, or as a Johnson Controls N2 protocol slave. Choice of reply protocol is made by the Integra on the basis of the format of request, so that a Modbus request receives a Modbus reply, and an N2 protocol request receives an N2 protocol reply. 6.
The data format in RTU mode is: Coding System: Data Format: 8-bit per byte 4 bytes (2 registers) per parameter. Floating point format ( to IEEE 754) Most significant register first (Default). The default may be changed if required - See Holding Register "Register Order" parameter.

Modbus Holding Registers and Integra set up Holding registers are used to store and display instrument configuration settings. All holding registers not listed in the table below should be considered as reserved for manufacturer use and no attempt should be made to modify their values. The demand parameters may be viewed or changed using the Modbus protocol. Each parameter is held in the 4X registers. Modbus Function Code 03 is used to read the parameter and Function Code 16 is used to write.
Relay Pulse Width is the width of the relay pulse in multiples of 20 ms. However, only values of 3 (60 ms), 5 (100 ms) or 10 (200 ms) are supported. Writing any other value will cause an error to be returned. Reset Energy is used to reset the Energy readings. A value of zero must be written to this register to accomplish this.
