that the correct device is being addressed. This process is known as commissioning the customer
interface unit. Commissioning only needs to be done once, typically at the time of installation, and
there is no need for the customer to be aware of the process. To this end it has been made
deliberately obscure, to obviate inadvertent malfunctioning of the system as a result of the customer
tampering with the customer interface unit.
To expedite the commissioning process, new customer interface units are delivered in a
decommissioned mode. Immediately on powering up it will present with the following display.

It is important to ensure that the battery is fitted in the customer interface unit
before commissioning can take place. If the battery has been removed or is very
flat, commissioning will be inhibited and an error message displayed (error 40).
The commissioning process is as follows:

In the case of a CTS meter, enter the meter number and hold the last digit for 5 seconds or until
a second beep is heard.

In the case of an STS meter, enter the entire STS 11 digit meter number - no need to hold the
last digit down for 5 seconds
– the number is accepted after the last digit is entered.

The meter number label is supplied with the packing kit of the meter and must be affixed to the
customer interface unit at the time of installation for future reference.

The scrolling busy display is shown.

If the process is successful and the meter responds, the customer interface unit beeps once
and the current meter status is displayed. The customer interface unit is now
commissioned .
NB: A configurable option at the time of manufacture
– 11.14 can be set such that on
successful commissioning the meter opens the load switch for a period of 10 seconds. This to
give a positive indication that the correct meter is connected to the customer‟s premises.

Caution may need to be exercised with this procedure because the brief power
interruption could cause appliances such as refrigerators and air conditioners to
trip. Also note that this load switch opening function would not occur if the meter
was, for example, out of credit, and the load switch already open.

The commissioning process will fail if no communication with the target meter is established.
This could take a couple of minutes due to multiple communication retries . The customer
interface unit will then briefly display the communication error fault code (30) before reverting to
the decommissioned display ( ???? ). Note that it is possible to terminate the communication
retries at any stage by pressing and holding the backspace information key.
If, at any stage, it is required to connect the customer interface unit to another meter, it will be
necessary to first
decommission it
– 10.5.
Once commissioned, the customer interface unit will communicate as required with its associated
meter.
10.5 Decommissioning
In order to decommission a customer interface unit, it does not have to be in communication with a
meter, nor does it need to be connected to the AC mains supply (it can be done under battery power).
The process of decommissioning is as follows:
