Tyco Electronics Integra Ci3 Installation Instruction
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 p ower
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 John son 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.

is used to select the Energy parameter screens.
In set-up mode this is the “Enter” button.
1.6 Display Mode
The parameters are viewed on a backlit LCD screen. There are 15 screens accessible via 4 buttons on the
front panel allowing the user to navigate between the various screens.
1.7 Set Up Mode
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 to confirm the input has been “set” to the desired
value. In general, the
and buttons change a parameter value and the key enters the value.
1.8 Start Up Screens
When power is initially applied to the Integra Ci3 digital meter, it progresses through a series of three startup screens. The first screen provides a visual check of the LCD screen by lighting up all the LCD segments.
The second displays the unit’s firmware version; whilst the third displays a start-up self test result. If this self
test is successful, the unit then switches to the default “Voltage” screen.

3. Set Up
Set up of the Integra Ci3 digital meter may be carried out by using either the local display or the Integra Ci3
digital meter configurator software. The Integra configurator software has its own on-line guide which can be
downloaded from our web-site www.crompton-instruments.com. Additionally, if required, set up parameters may
be manipulated directly via the RS485 communications interface. The following sections give step by step
procedures for configuring the Integra Ci3 digital meter using the front panel.
To access the Set-up screens, press and hold the and the
buttons simultaneously for five seconds. This
displays the password entry screen. Password protection is designed to prevent unauthorised access to Set-up
screens. Password is normally set to 0000 when a product is shipped. When exiting Set-up mode, the
instrument returns to the last selected Display screen. To return to the Display screens at any time during the
set-up procedures, press the and the
buttons simultaneously for five seconds, or keep pressing the back
button . Any set up changes that have already been made will be retained.
3.1 Number Entry Procedure
When configuring the unit, many screens require the entry of a number, usually on the middle row of digits.
For example, on starting the set-up section, a password will be required. The procedure is as follows: press
the
and buttons to change the digit value that is flashing on the screen. Press the button to confirm
the entry and move to the next digit in the sequence. The digits are set one at a time, from left to right until
all four digits are set. At any time during this operation it is possible to press the button to move back to
the previous digit in the sequence.

Menu navigation
Once the correct password has been entered the user can access the first level menu structure. Use the
and
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. Once all the necessary selections have been made and the
required settings entered, press the to return to the first level menu structure.
The following example shows how to set the CT primary.
Press and hold the two outermost buttons and
simultaneously for five seconds
until the password screen is displayed.
Press
four times to enter the default password of “0000”.
The system setup screen will be displayed on the screen. Press the
button to scroll
down the menu until you see the CT primary setting screen.
Press the
button to enter the CT primary setting screen. The first digit should start
flashing.
Use the
and buttons to set the digit to the required level then press to confirm.
Repeat this process until all four digits have been set to the desired CT primary value.
(e.g. 100A = 0100A, 1000A = 1000A)
The word “SET” should be displayed after the fourth digit has been entered to confirm
that the primary CT value has been set.
Press to return to the first level menu structure. At this point it is possible to scroll
up and down the first level menu structure so that the user can adjust another
parameter (e.g. system configuration, or comms etc).
If no other setting are required then press to exit set-up mode and return to
measurement mode.
5. Set up screens
You enter the set up screens at 5.2, press
to get to 5.1 and to get to everything else.
5.1 CHNG PASS (Change password)
Selecting this screen takes the user to the new password screen, to enter a new four digit password
between the values of 0000 and 9999.
Use the
and buttons to set the digit to the desired number then press to confirm.
Repeat this process until the desired 4 digit password has been set.
