5 ALARMS
To allow time for the system to stabilise after paralleling takes place, the Supervision Timer is
provided.
Supervision of the alarm system activates after both supplies are seen to be in parallel. This check is
performed using the digital inputs for Generator Closed Auxiliary and Mains Closed Auxiliary.
During the Supervision Timer, the Sup LED flashes green. After the timer has expired, the
Supervision of the alarms is fully active and the Sup LED ceases flashing and illuminates continuously
green.
5.1 RESET
After the alarm has been cleared, the module must be ‘reset’ in order to reactivate Supervision.
Reset is performed in the following ways.
•
Manual Reset. Press the button.
•
Auto-reset (when configured). After the supply returns within limits, the configurable Delay
timer operates. After this, the Auto-Reset function operates.
•
Fast Reset (when configured). If the supply failure occurs for less than the time of the
configurable Fast Reset Window, the Fast Reset Delay timer operates. This allows for a Fast
Reset upon a short term failure.
5.2 UNDER FREQUENCY / OVER FREQUENCY
These are ‘2 stage’ alarms.
Stage 1 allows for a delayed operation should the frequency stray by a small amount.
Stage 2 allows for a faster trip should the frequency change by a larger amount.
Indicates that one of more of the phases are outside the settings of the Under Frequency / Over
Frequency Alarms.
5.3 UNDER VOLTAGE / OVER VOLTAGE
NOTE: DSEP100 modules before V1.5 have two stage alarms only. These modules are able
to be updated using the DSE Configuration Suite PC Software.
These are ‘5 stage’ alarms.
Stage 1 allows for a delayed operation should the voltage stray by a small amount.
Stages 2 to 5 allow for a faster trip should the voltage change by a larger amount.
Indicates that one of more of the phases are outside the settings of the Under Voltage / Over Voltage
Alarms.
