23
Bypass Voltage Bad
Bypass voltage value is out of limit while UPS was operating on the bypass
mode.UPS will switch to normal mode if temperature and load status are
normal.If not ,UPS will stop.
24
Bypass Freq. Bad
Bypass frequency value is out of limit while UPS was operating on the bypass
mode.UPS will switch to normal mode if temperature and load status are
normal.If not ,UPS will stop.
25
Coil Overtemp
Over temperature is observed for UPS’ inverter and rectifier coils.
26
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.
27
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.
28
Maint. BYP. Sw. Off
Maintenance bypass switch is deactivated.
29
Ambient Nor.
Temp.
UPS ambient temperature has got back to allowed limit values.
30
Mains Voltage Nor.
Mains voltage is in the limited values , UPS will switch to normal mode.
31
Inverter Nor.
Temp.
Inverter temperature is in the limited values .If load and temperature values
are normal, UPS will switch to normal mode.
32
PFC Nor. Temp.
Rectifier temperature is in the limited values .If load and temperature values
are normal, UPS will switch to normal mode.
33
Charger Nor. Temp.
Charger/booster module temperature is in the allowed limits , charging will be
activated again.
34
STS Nor. Temp.
Temperature of Static transfer switches is in the allowed limit.
35
Bypass Voltage
Nor.
Bypass voltage is within defined limits.
36
Bypass Freq. Nor.
