For all alarms check the following where
applicable:
•
SC200 LED status.
•
SC200 display indication.
•
DCTools alarm indication
•
Remote alarm indication (PowerManagerII,
SNMP traps, etc)
•
Digital outputs (relays).
Reducing the alarm recognition time will reduce
the alarm testing time.
There may be more than 1 method to perform
the following alarm tests.
Increase the Low Float Threshold to just below the
float voltage.
Reduce the system voltage by heating the battery
temperature sensor
- or -
Disconnect the battery from the system.
Start a Battery Test.
The system voltage will fall.
Ensure alarm operates.
Test as for the Low Float test.
Note that the Low Load Threshold is lower than
the Low Float threshold.
Ensure alarm operates.
Set the system Float Voltage above the High Float
Threshold.
- or -
Reduce the High Float Threshold and increase the
system voltage by starting an Equalize.
- or -
Reduce the High Float Threshold and increase the
system voltage by cooling the battery
temperature sensor.
Ensure alarm operates.
Increase the system voltage.
Test as for the High Float test.
Note the High Load Threshold is higher
than the High Float Threshold
Ensure alarm operates.
Turn off a rectifier AC MCB (if fitted).
The rectifier will turn off.
Ensure alarm operates.
