The set credit levels token is not defined in the STS specification. It is a
Cashpower specific feature, and it uses one of the proprietary dispenser
specific management token subclasses.
4.5.7
Clear Credit Token
On accepting a clear credit token, the meter clears any remaining credit to zero and opens the latching relay,
thus interrupting the electricity supply to the customer.
4.5.8
Initiate Dispenser Test Token (Meter Non-Specific Token)
There are a number of non meter-specific tokens that can be used to test various functions on the meter.
On accepting an initiate dispenser test token, the meter executes all the tests that are embedded in that
particular token. The following tests are supported:
Function

Test all the above functions (tests run
sequentially)
5649 3153 7254 5031 3471
In a test sequence (test all), each test has a duration of 2.5 seconds, and is performed in the above order. For a
single test per token, the test duration is 5 seconds.
On completion of the test sequence, the meter returns to its normal mode of operation.
4.5.9
Commissioning Token (Non Meter-Specific, Proprietary Token)
This is a proprietary STS token i.e. it can only be used on a Gyr
STS meter:
1268 2136 5508 1001 3746.
This is a non meter specific
number.
It is typically used to assist meter installation personnel by ensuring that the load remains disconnected and the
tamper detect sensing switch function disabled (meter decommissioned).
Once the installation is complete and the number entered:
The latching relay closes
The tamper detect sensing switch function is enabled.
4.5.10 Commissioning Token (Meter-Specific, Proprietary Token)
This is a meter-specific token but in all other aspects its operation is the same as described in the paragraph
above.
Note: An already commissioned meter rejects a commissioning token.
4.5.11 Decommissioning Token (Meter-Specific, Proprietary Token)
On accepting a decommissioning token, the meter opens the latching relay (load disconnected) and disables
the tamper detect sensing switch function.
Note: An already decommissioned meter rejects a commissioning token.
