7.5.1.1
Electricity Credit Voucher
The electricity credit voucher transfers a variable quantity of credit to the meter.
7.5.1.2
Set 1st Dispenser Key Voucher
Key changes are occasionally carried out to maintain the security of a pre-payment system.
Unless the prepayment vending system and meter are both operating on the same key, vouchers
vended from that system will not be accepted by the meter.
To effect a key change, two vouchers (set 1st dispenser key and set 2nd dispenser key) need to be
issued and entered into the meter within a 5-minute period of each other. NB: Set 1st dispenser
key and set 2nd dispenser key vouchers may be entered in any sequence i.e. the 2nd dispenser
key voucher may be entered first.
Various ancillary functions e.g. clearing the meter log may be embedded into the
key-change process (refer to the STS specification).

Set 2nd Dispenser Key Voucher
Refer to
– 7.5.1.2.

Clear Tamper Voucher

voucher. Note that these vouchers also reset the power-fail counter and the significant reverse
energy flag (if it had been set)
– 11.18.

Set Power Limit Voucher
This voucher sets the power limit level for the meter
– 7.8.
7.5.1.6
Set Credit Levels Voucher (Proprietary Voucher)
On accepting a power limit level number, the meter sets the appropriate high and low credit levels.
These are the levels at which the segments in the „wedge‟ of the LCD credit indicator toggle – 6.6.
7.5.1.7
Clear Credit Voucher
On accepting a clear credit voucher, the meter clears any remaining credit to zero and opens the
load switch, thus interrupting the electricity supply to the customer.
7.5.1.8
Initiate Dispenser Test Voucher (Meter Non-Specific Voucher)
There are a number of non meter-specific vouchers that can be used to test various functions on
the meter.
