EMBS port is open or the maintain switch
sensor (connected to EMBS port) is trigged.
(The UPS is transferred to bypass).
Parallel cable is still not connected well when
restart after the parallel system is fault
because of parallel communication failure.
(When this warning appeared, the UPS could
not start up because it is system protection
for parallel system)
The internal converter failed, so the DC bus
voltage could not be boosted correctly.
1)
DC bus voltage is too high because of
mains input or load transient current.
2)
The internal converter failed.
The internal converter failed, so the DC bus
voltage is too low.
1)
The load is special or abnormal, so the
internal positive and negative DC bus
voltages are unbalanced.
2)
The internal converter failed.
The internal inverter failed, so the inverter
voltage could not start up
The internal inverter failed, so the inverter
voltage is too high.
The internal inverter failed, so the inverter
voltage is too low.
Short circuit occurs on the UPS output.
UPS output power is negative. It means there
is energy feedback into the internal of UPS
from output. It may be caused by
regenerative load or current control failure in
the parallel system.
The internal battery SCR is failed and short.
The internal inverter relay is stick to short or
the SCR of STS (Static Transfer Switch) is
short.
Parallel cable for communication is not
connected well in the parallel system.
The output current is extremely unbalanced
between the paralleled UPSs or there is an
error in the parallel system.
The internal temperature is too high and
reach the fault level (shutdown):
1)
Maybe the environment is hot.
2)
Maybe the fan is blocked or failed.
3)
Maybe ventilation is blocked by the wall
or other goods.
4)
Load is too heavy.
Internal communication failure between
CPUs.
Overload time is out of the specification and
the UPS shuts down automatically.

If the EMBS port is short-circuited, the
warning will disappear.
1)
If the system is still needed to be
operated in parallel mode, please
connect the parallel cable well. And,
choose "Para Unlock" in control
menu to remove the warning. Then,
the UPS could start up.
2)
If the UPSs in the system are
separated to single UPS, please
disconnect the output to other UPSs
and choose "Para Unlock" in control
menu to remove the warning. Then,
the UPS could start up.
NOTE: Be careful to check the UPS
operation mode (parallel or single) and
the connections. If the parallel cable is
not connected in the parallel mode, the
UPS may be damaged.
Contact the dealer to repair.
1)
Shut down and restart the system to
see if it happens again.

Make sure the ambient temperature
not over 40ºC.
2)
Make sure the fan is OK.
3)
Make sure ventilation is well.
