39 • TROUBLE SHOOTING
________________________________________________________________________________________________
8. TROUBLE SHOOTING
Upon fault – load stops, Fault LED lights and Fault Relay operates (as programmed). The LCD shows TRIP:
and fault description. (for example: TRIP: UNDER CURRENT).
Fault Massage Cause and trouble shooting
UNDER CURRENT Trips/Alarms if UNDER CURRENT conditions exist.
For more information on adjusting UNDER CURRENT refer to section
7.7.5 on page 32
OVER CURRENT Trips/Alarms if TPS if UNDER CURRENT conditions exist.
For more information on adjusting OVER CURRENT refer to section
7.7.5
on page 32
UNBALANCE LVL 1,
UNBALANCE LVL 2
Trips/Alarms if UNBLANCE LEVELS exist.
This alarm can be used when symmetrical load is connected to alert faulty
elements.
In case of an a-symmetrical load disable this protection.
Check load for faulty elements.
For more information on adjusting UNBALANCE LVLs refer to section
7.7.5
on page 32
UNDER VOLTAGE,
OVER VOLTAGE
Trips/Alarms if UNDER/OVER VOLTAGE conditions exist.
For more information on adjusting UNDER/OVER VOLTAGE levels refer
to section
7.7.5 on page 32
PHASE LOSS Trips/Alarms when one phase is missing.
When two/three phases are missing the UNDER VOLTAGE alarm will
show.
Check connections to TPS.
GROUND FAULT Trips/Alarms when line currents measured are not summed to zero.
This alarm does not function when using WYE NEUTRAL CONNECTED.
Check load for ground fault.
Note: This alarm is very sensitive.
Disable this protection in case of consecutive nuisance alarms.
UNDER POWER Trips/Alarms when power derived from mains is lower then power
programmed to TPS.
This alarm can be used when an a-symmetrical load is connected to alert
faulty elements.
Check load for faulty elements.
