8. Alarm Functions
The FSx series charger includes comprehensive fault protection
and alarm monitoring. Charger alarms are graded into urgent and
non-urgent alarms.
Urgent alarms indicate a serious condition, and the charger
will stop the charge cycle.
Non-urgent alarms are indicated on the front panel and
recorded in the alarm log, but will not interrupt a charge cycle.
Non-urgent alarms can be expected to occur from time to time due
to the varying charge characteristics of batteries. Should non-urgent
alarms consistently arise, further investigation should be made.
If an urgent alarm occurs mid-charge cycle the charger stops,
illuminates the red Alarm LED on the front panel display and
indicates an urgent alarm event by alternating both large green and
red LED lamps.
If a non-urgent alarm occurs mid-charge cycle amber Alarm LED on
the front panel display illuminates and the large red LED lamp
flashes.
In both cases the alarm is logged into the memory of the MPC in
the form of an alarm log that can be downloaded at a later date to
aid fault diagnosis. In the PC application the relevant alarm name
highlight changes from green to red.
