Crompton Instruments 1.Introduction 1.1.Unit Characteristics
1 Introduction
This document provides operating, maintenance and installation instructions for the Crompton
Instruments Integra Ci1 energy meter. The unit displays imported or exported real and reactive
energy, since it was last reset, in terms of Wh, kWh, MWh, VArh, kVArh and MVArh for single
phase, three-phase 3-wire or three-phase 4-wire supplies. In order to measure energy, the unit
requires voltage and current inputs in addition to the supply required to power the unit. The current
input(s) are obtained via current transformers (CTs).
The unit can be configured to work with a wide range of CTs, giving the unit a wide range of
operation. Option modules can be fitted to provide pulse and RS485 Modbus™/JC N2 outputs.
Configuration is password-protected.
The unit can be powered from a separate auxiliary a.c. (or d.c.). Alternatively it can be powered
from the monitored supply where appropriate.
1.1 Unit Characteristics
•Active Energy (Wh, kWh or MWh)
•Reactive Energy (VArh, kVArh or MVArh)
The unit has password-protected set-up screens for:
•Changing password.
•CT primary current (1 to 9999A)
•Energy reading reset
•Pulse output duration and rate divisor (option)
•RS485 serial Modbus™ or JC N2 format (option)
Pulsed relay outputs, indicating energy, and an RS485 output are available as optional extras. The
RS485 output option allows remote monitoring from another display or a computer.
1.2 Current Transformer Primary Current
The unit can be configured to operate with CT primary current of between 1 and 9999A. Maximum
CT primary current corresponds to a maximum input current to the unit of 5A.
1.3 RS485 Serial Option Modbus™ or JC N2Protocol
This option uses an RS485 serial port with Modbus™ or Johnson Controls (JC) N2 protocol to
provide a means of remotely monitoring and controlling the Ci1 unit. Both protocols are supported
in the same unit. Full instructions for RS485 port can be found in Section 4.6.
1.4 Pulse Output Option
This option provides one or two relay pulse outputs that clock up measured active (Wh) or reactive
(VArh) energy. The unit can produce one pulse for preset quantity of energy imported or exported.
Pulse rate divisor and width are configured from the Set-up menu, as detailed in Section 4.7.

2.Start Up Screens Crompton Instruments
2 Start Up Screens
The first screen lights all LED segments and can be used as a
display LED check.
The second screen indicates the firmware installed in the display
unit. This example shows a version number of 10.06.
Next the unit performs a self-test and the screen indicates if the test
is passed.
After a short delay, the default measurement screen appears.
3 Measurement Mode
In measurement mode, the buttons control the displayed measurement as follows:
Displays the maximum current that can be monitored. This
reading is set on installation according to the current
transformer in use. The small ‘A’ on the bottom line indicates
that the display is showing Amperes.
Displays active energy measured since the unit was last reset.
The display alternates between Imported and Exported energy
each time the button is pressed. The bottom line of the display
shows the import/export mode and the Wh, kWh or MWh range.
The and/or symbol on the top line flashes each time
an output pulse is generated.
Displays reactive energy measured since the unit was last
reset. The display alternates between Imported and Exported
reactive energy each time the button is pressed. The bottom
line of the display shows the import/export mode and the VArh,
kVArh or MVArh range. The and/or symbol on the
top line flashes each time an output pulse is generated.
This display indicates the phase sequences of the measured
voltages and currents, allowing a check that they are connected
correctly. The sequence can be 123 or 132 but voltage (V) and
current (I) sequences must be the same. A ‘V1--‘ or ‘I --‘
display indicates a phase error of voltage or current,
respectively.
The top line of the display indicates the type of supply being monitored:
Single phase 3-phase 3-wire 3-phase plus N (4-wire)
The blue man flashes to indicate that energy for the currently displayed parameter is being
accumulated.

4 Setting-Up
To enter set-up mode, firmly press the and buttons simultaneously and hold for about
5 seconds until the password screen appears. Setting-up is password-protected so
you must enter the correct password (default ‘0000’) before proceeding. If an incorrect password
is entered, the display reverts to measurement mode.
To exit setting-up mode, press repeatedly until the measurement screen is restored or hold
and buttons simultaneously for 5 seconds.
