Integra Ci3 digital metering system
1. Features and options
The Integra Ci3 digital meter is designed for accurate measurement and display of all major electrical and power
quality parameters. It is has been designed, developed and manufactured in the UK, by Crompton Instruments.
It is user programmable to suit single-phase two wire, three-phase three-wire, and three-phase four-wire system
configurations.
The product features a DIN 96 panel mounted snap-fit enclosure, backlit Liquid Crystal Display (LCD) and user
programmable CT ratios, accessible via an intuitive user interface. The Integra Ci3 digital meter measures 17
electrical parameters including total harmonic distortion (THD) up to the 31st harmonic.
The Integra Ci3 digital meter offers two output ports at the rear of the product. This allows to fit either two
isolated pulsed output relays or a RS-485 communication module to allow Modbus protocol or Johnson Controls
communication output. These are configurable via internal settings.
1.1 Power Supply
The Integra Ci3 digital meter must be powered from an auxiliary AC or DC supply that is separate (but it may
also be commoned) from the metered supply. The input range of the auxiliary is 110-400V AC or 120-350V
DC. All connections are made to screw clamp terminals that accept 0.05 - 2.5mm
cables. Terminal screws are fully tightened for shipment and must be undone before wire insertion.
Terminal screws should be tightened to 0.5 Nm (4.4 lbf in) only.
1.2 RS485 Module Option
An optional RS485 module is available for purchase. Where a RS485 module is available, it can be
connected to a PC for control and monitoring purposes using either Modbus protocol or Johnson Controls
protocol. A maximum of one RS485 module can be fitted to an Integra Ci3 digital meter.
1.3 Pulse Relay Module Option
An optional Pulsed Relay module is available for purchase. Pulse relays are user programmable for
corresponding energy type, pulse divisor (one pulse for every 0.1, 1, 10, 100 or 1000kWh/kVArh for
example) and pulse width (duration). A maximum of two Pulsed Relay modules can be fitted to an Integra
Ci3 digital meter, when no RS485 module is fitted. When two Pulsed Relay modules are fitted, they share a
common divisor value and pulse width.
1.4 Display Screen
The display screen is used in two main modes: display of measured values and parameter setup.
1.5 Front Panel Buttons
The front of the product has four buttons that select different electrical parameters and are also used for
system configuration.

Use the buttons to navigate up and down this level until the desired parameter is reached. Then press the button to select the desired parameter and enter the second level menu structure. For some parameters such as COMS there is an additional third level menu structure.
- Page 6 5.3 CT (CT Primary) This screen is used to set the value of the CT primary to be used with the Integra Ci3 digital meter. E.g. setting this screen to 0100 (100A) will tell the product that a 100/5A CT is being used on the current input and this value will be used to correctly calculate all Current and Power measurements etc.
- Page 7 This screen displays the floating point number byte order, either Norm (Normal) or Rev (Reverse). *Note: No adjustment of this parameter is allowed via the front of the Integra Ci3 digital meter. Changes to the floating point number byte order must be made on the Modbus system; for information on how to adjust this setting please refer to the Integra Communications Guide, available from our web-site.

The Integra Ci3 digital meter should ideally be powered from a dedicated supply, however it may be powered from the signal source providing the source remains within tolerance of the auxiliary supply voltage range.
