General icon indications
Low credit indication
When the remaining credit in the meter reaches or is lower than the configurable low credit threshold,
the buzzer will emit two short beeps. The audible warning will repeat until silenced by the consumer.
Silencing the buzzer is achieved by pressing the backspace key for three seconds.
If credit is not inserted then the audible low credit warning although acknowledged will be repeated
approximately every 24 hours. Should the UIU power up into a low credit condition the audible warning
will restart.
The hand icon (token required) will flash, indicating that a
credit token is needed.
Zero credit indication
When the available credit reaches zero the disconnection switch suspends the supply of electricity to
the consumer. The “token required” icon will be permanently displayed.
Negative credit indication
Important
When credit is entered into the meter, the negative credit value is first deducted from the
credit entered and only the balance will be displayed.
Under certain circumstances e.g. through switching delays or disconnection switch failure, the
consumer may continue consuming power after all remaining credit has been consumed.
This consumption is registered in the meter as negative credit and is displayed as a negative reading;
alternatively the meter can be configured, at the time of manufacture, so that the display continues to
indicate
0,00
kWh
whilst the meter registers the negative credit.
The “token required” icon continues to be displayed and the “supply status” icon is not displayed.
An example of a negative credit display is given below:
