Autometers Systems IC 970 Istruzioni per l'installazione
The IC 970 is the latest meter in the IC 900 series
of Information Centres from Autometers Systems
Ltd. With new advances in micro processors and
new added features, the meters are user friendly,
easy to install and simple to programme.
The IC 900 range of Information Centres are electronic meters and great care has been taken to
ensure that they meet the stringent requirements of all the potential users and specifiers of the
product, from the buyer who wants a competitively priced product, the installer who wants
simple fitting with good connection terminals to the end user who wants a quick and easy means
of obtaining information. The IC 900 range of meters meets these varied demands.
The IC 970 meter has been designed to communicate with other systems by means of either pulse
outputs standard on all IC 900 meters or via a separate plug in communication module which is
sold with the meters or can be retro fitted at a later date.
All the IC 900 range of meters have been designed to communicate with Autometers Systems Ltd
Horizon range of data collection units, this enabling complete measurement and data collection
systems to be built up.
A new feature to the IC 970 is the protocol set up information which can be viewed on the display
when a communication module has been installed.
There are two optically isolated volt free relays outputs on the IC 970 and IC 990, one relay for
kWh and the other for kVah. Both these relays are fully programmable to adjust the value of the
pulse (4 settings) and the time of the contact closure. Both meters are factory set to 1 imp/kWh
and 1 imp/kVah.
An optional communication module can be fitted to the IC 970 and IC 990 meters offering a wider
range of information which can be transferred to a BMS system.

You will notice the cursor is flashing at the first digit on the left of the two digits. Press the key
with 1 on it, the cursor will now move to the next digit, now press 2.
2.Press Enter.
The display will change to.
Press Enter. This will RESET The Maximum Demand and take you back to the default register.
To check you have reset the max demand press the “Max demand” key all numbers should have
reset to zero.

When you receive the meter there will be at least one value that you must programme into the
meter. This is the current transformer ratio. If you want to monitor the neutral current then the
neutral current transformer ratio will also need to be programmed.
If the meter has been purchased with the communication module you may need to alter the
standard protocol set up. See page 17 & 18 For communication module set up.
First you must locate the two red binary switches on the back of the meter.
See connection details page 3.
You will see two sets of RED binary switches with numbers 1-8 on each of them.
SELECT the binary switch with the word “func” above and switch number 8 to the “on” position.
This puts the meter into programming mode.
Important.
When you have completed programming the meter you must switch number 8 to the “off”
position.

When you press the information key and the communication module is fitted the following displays
will appear.
To move on to the displays shown below press the “INFORM” key repeatedly until
the required display is shown.
Please Note.
If there is no communication module fitted, you will only see displays 1, 4, 5, 6, 7, 8, 9 & 10.
You will notice in the picture below two red vertical rows of switches 1 - 8. Above each row the
letters “ADDR” and “FUNC” are printed. These individual switches will have to be selected to
programme the correct protocol in the meter. See below.
You will notice two red binary switches next to each other, one is marked “ADDR” and the other
switch is marked “FUNC”.
The binary switch has 8 switches numbered 1-8.
The number sequence is as follow.
1 = 1 3= 4 5= 16 7 = 64
2= 2 4= 8 6= 32 8 = 128
“ADDR” Binary Switch
The binary switch on the left is marked “ADDR” and is for setting the meters address number.
Each meter in the Modbus system must have its own unique number.
E.G. by moving the number 1 switch to the “on" position you have numbered this meter as 1.
By switching numbers 1 and 4 to the “on” position this becomes number 9.
The highest number which you can allocate to a meter is 128.
