PROBLEM
POSSIBLE CAUSE
CORRECTIVE ACTION
A. “ALARM” L.E.D. illuminated
1. See Section II - G: Status and Alarm
Contact Wiring for proper status
contact wiring.
2. One or more Power Modules not
outputting current.
2. Verify Power Module is wired
correctly. See Power Module
Installation/ Operation manual to
verify proper operation.
3. LVD in disconnect position.
3a. Verify LVD switch is in the “AUTO”
position.
3b. Check to see if battery voltage is
below the LVD disconnect threshold.
If so, remove load and recharge
battery.
3c. Check to see if LVD disconnect
voltage is set too high. See Section
III-D for LVD adjustment procedure.
4. PFM load circuit breaker tripped.
(Breaker is in mid-trip position.
Note:
Breaker will not activate
the “ALARM” L.E.D. if manually
switched into the off position.)
4. Identify cause of over-current
condition and reset breaker.
B. LVD contactor rapidly cycles between
open and closed
LVD out of adjustment.
See section III-D for LVD adjustment
procedure.
1. Status contacts for one or more
power modules or other monitored
equipment mis-wired.
IV) TROUBLESHOOTING
C. LVD disconnects battery from load
too soon-batteries not low.
1. Disconnect threshold set too high.
2. Large voltage drop between (+) or
(-) battery terminal and BATTERY HOT
input post.
3. Sudden voltage drop due to heavy
intermittent load.
1. See section III-D for LVD
adjustment procedure.
2. Shorten wire length and/or
increase wire size. Check for loose
connections.
3. Increase battery capacity or test
and replace batteries if necessary.
