A01 O/P OVERCURRENT
Check the new load which are connected to UPS nowadays the total load power maybe exceeds maximum
power of the UPS. Otherwise call service.
A02 OVERTEMP SHUT
Inverter modüle heatsink temperature is out of tolerance check the followings:
-If UPS air inlets and outlets covred by dust clean
-If any material prevents air flow at UPS air inlets or outlets take the material
-If UPS ambient temperature is high then 45 C, use air cooling system
A03 BATT HIGH
DC BUS voltage or battery voltage of the UPS is high, if inductive load is used this event sometimes occures if
alarm continues call service.
A04 OUTPUT V.LOW
The output voltage of the inverter is low call service
A05 OUTPUT V.HIGH
The output voltage of the inverter is high call service
A06 OVERLOAD SHUT
The total load which is connected to the UPS is exceeded 100% capacity of the UPS if message continues call
service they will check UPS, but probably you need higher power range UPS.
Note: Some load inrush curents causes overload event then current is normal.
A07 SHORT CIRCUIT
There is short circuit at the output of the UPS check installation and loads.
A08 ON MAINTENANCE
The maintenance by-pas switch of the UPS is ON <1>position, there is a lock on this switch which prevents
unauthorized personnel use.
A09 MANUAL BYPASS
Load is transferred to by-pass from UPS command menu, transfer the load to the inverter.
A10 BATTERY LOW SHUT
The DC BUS or battery voltage of the UPS is low. If the mains is OKEY call service.
If the there is nomains voltage wait until mains OKEY UPS will start automatically.
A11 REPO STOP
External repo button pressed, to restart turn off and on the UPS
A12 DC BALANCE BAD
Call service
A13 PEAK CURRENT
Very high curent measured at the UPS output, check loads
A14 INV NOT START
Call service
A17 BYPASS FAILURE
,
A18 BYPASS VOLT
,
A19 BYP FREQ.TOLER
The input of the UPS or by-pass input of the UPS voltage or frequency is out of tolerance ,wait until the voltage
is normal if message continues long time check input fuses ,switches etc. at the distrubution panel.
A20 OVERLOAD
UPS is currently running but the load percentage exceede 100% capacity of the UPS ,if this situation continues
inverter will stop after a delay.Check the loads at the UPS output.
