29 Inverter Voltage Bad
Inverter voltage is out of limit. Load will be transferred to bypass line,
when inverter voltage gets back to normal values,UPS will switch to
normal mode again.
30 Overload
Output load value is over %105, overloading counter will start to count,
If UPS is on normal mode, the charging will be stopped until load value
gets back to normal.
31 Maint. BYP. Sw. Off Maintenance bypass switch is deactivated.
32 Ambient Nor. Temp. UPS ambient temperature has got back to allowed limit values.
33 Mains Voltage Nor. Mains voltage is in the limited values, UPS will switch to normal mode.
34 Inverter Nor. Temp.
Inverter temperature is in the limited values. If load and temperature
values are normal, UPS will switch to normal mode.
35 PFC Nor. Temp.
Rectifier temperature is in the limited values. If load and temperature
values are normal, UPS will switch to normal mode.
36 Charger Nor. Temp.
Charger/booster module temperature is in the allowed limits, charging
will be activated again.
37 STS Nor. Temp. Temperature of Static transfer switches is in the allowed limit.
38 Bypass Voltage Nor. Bypass voltage is within defined limits.
39 Bypass Freq. Nor. Bypass frequency is within defined limits.
40 Coil Normal temp.
UPS inverter or rectifier coil temperature has got back to normal
values.
41 Inverter Volt. Norm.
Inverter voltage is in the limited values, UPS will switch to normal
mode.
42 Normal Load Output load is under %100, If charging was OFF, It will be ON .
43 BYP Thyr.L1 Short C.
UPS has detected short circuit at bypass L1 thyristor. UPS will shut
down.
44 BYP Thyr.L2 Short C.
UPS has detected short circuit at bypass L2 thyristor. UPS will shut
down.
