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 measurem

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. 1.3 Secondary Voltage 0240 0340 0440 0640 1000 15

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. Where the

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. Voltage display In Set up mode, the top row shows an abbreviation of the parameter name, the middle row shows the parameter value being set and the bottom row is used for confirmation of

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). 2.3 System Screen 0240 0340 0440 0640 1000 1540 The
