Problem Solution(s)
Redundancy
Alarm
The total load current has exceeded the summed current capacity of “N”
number of rectifiers in an “N+1” redundant system. Add more rectifiers, or
reduce system load to maintain redundancy.
Temp. Probe
Alarm
Temperature probe(s) have been removed from the Temp / Aux input terminals
of the controller. Insert the temperature probes back into proper positions.
Thermal
Runaway
Battery Temperature has exceeded the T Runaway Temp set point, and the
plant voltage has been reduced to the thermal Runaway V set point. Check to
make sure the proper ventilation is available for the batteries.
Unknown
System
Controller is displaying Unknown System. During new installation / turn up of
the plant, make sure at least one rectifier module is inserted in the shelf.
Rectifier Alarms
LED (Red)
Rectifier’s Alarms LED is Red. AC OK, & DC OK LEDs are off. Make sure rectifier
shelves are not wired for 120V, 1 Phase AC input.
Controller Not
Responding
Power cycle the controller by disconnecting it from the backplane of the shelf
(it does not need to be removed, just powered off), and then reconnecting the
controller to the shelf. Wait for 3 minutes or more to see if the message
“Controller not responding” returns.
If the message “Controller not responding” returns, or if the message “Starting
App” persists (without returning to the main screen), contact Eltek Technical
Support.
