Autometers Systems IC 970 Installation instructions

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.

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.

Current Transformer Selection
For accurate monitoring, correct selection of current transformers are critical. The following
paragraphs provide the information required to choose these transformers.
The 900 range of meters use current transformers (CT) to sense the current in each phase of the
power feed. The selection of the CTs is important because it directly affects accuracy.
The CT secondary rating depends on the current input option installed. The standard IC 900
current rating is 5 amps.
The CT primary rating is normally selected to be equal to the current rating of the power feed
protection device. However, if the peak anticipated load is much less than the rated system
capacity then improved accuracy and resolution can be obtained by selecting a lower rated CT.
In this case the CT size should be the maximum expected peak current +25%, rounded up to the
nearest standard CT size.
Other factors may affect CT accuracy. The length of the CT cabling should be minimised.
Also the CT burden rating must exceed the combined burden of the IC 900, plus cabling,
together with any other connected devices.
Overall accuracy is dependent on the combined accuracies of the IC 900 METER and
the current transformers.

Field Service Considerations
In the unlikely event that a unit should fail, it will generally be serviced by exchanging the unit
for a replacement unit. The initial installation should be done in a way which makes this as
convenient as possible.
1. It is good practice that a current transformer shorting block is fitted, this enables the meter to
be disconnected without open circuiting the current transformers. The shorting block should be
wired so that the protective relays are not affected.
2. All wiring should be routed to allow easy removal of the connection to the terminals.
Disconnect From Supply
A suitable isolator for both voltage and current terminals shall be included in the wiring
installation, close to the meter with easy access and marked as the meters disconnect device.
If the equipment is used in a manner not specified by the manufacturer the protection provided
by the equipment may be impaired. Current measuring terminals are not intended to be
connected to voltages to earth above 50Vac.
