15
Maint.
BYP.
Sw.
On
Maintenance bypass switch has been activated.
16
Ambient
Abnor.
Temp.
The ambient temperature is over limit. Check the ventilation
of UPS room.
17
Battery
over
‐
current
UPS battery charge current is out of the specified limits.
Charge will be OFF until return to normal operating.
18
Mains
Voltage
bad
Mains voltage is out of the specified limits, UPS will switched
to battery mode.
19
Inverter
Overtemp.
Inverters temperature is out of limit, in case of 5 degrees more
increment, Load will be transferred to Byp
line
20
PFC
Overtemp.
Rectifier 's temperature is out of limit, in case of 5 degrees
more increment ,Load will be transferred to Bypass line.
21
Chrg
OverTemp.
Charge / boost module temperature is out of the specified
limits. If it is in charge mode, Charge will be stopped. If it is in
boost mode, UPS will be stopped.
22
STS
Overtemp.
Static Transfer Switches’ temperatures are out of limits. UPS
will be stopped.
23
Outp.PL1
Cur.
Limit.
Short circuit protection is activated for output L1 phase.
24
Outp.PL2
Cur.
Limit.
Short circuit protection is activated for output L2 phase.
25
Outp.PL3
Cur.
Limit.
Short circuit protection is activated for output L3 phase.
26
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.
27
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
28
Coil
Overtemp
Over temperature is observed for UPS’ inverter and rectifier
coils.
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.
