General notes about
alarm testing
•
For all alarms check the following where applicable:
•
SC200 or SC100 LED status.
•
SC200 or SC100 display indication.
•
DCTools/Web alarm indication
•
Remote alarm indication (PowerManagerII, SNMP
traps, and so on)
•
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.
Low Float
Note 1
•
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.
Low Load
•
Test as for the
Low Float
test.
Note that the
Low Load Threshold
is lower than the
Low Float
threshold.
•
Ensure alarm operates.
High Float
Note 1
•
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.
High Load
•
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.
Rectifier Fail
•
Turn off a rectifier ac circuit breaker (if fitted).
•
The rectifier will turn off.
•
Ensure alarm operates.
Multiple rectifier fail
•
Turn off the ac circuit breakers to 2 rectifiers (if fitted).
•
The rectifiers will turn off.
•
Ensure alarm operates.
Rectifier comms lost
•
Remove a rectifier from the system.
