Indicated alarm
1x (Imminent) stoppage as a result
of low battery voltage.
2x Stoppage due to overload in the
equipment, due to either a
short-circuit or too high a load
for the inverter.
3x Decrease in the rated output of
the device due to a too high
internal temperature.
4x Battery voltage higher than the
maximum limit set by the
parameter {1121}.
5x No transfer. Insufficient power
from the source
6x Startup prevented due to
unwanted voltage at the device
output.
7x Indicates missing voltage on one
of the units of the system in a
multi-unit configuration.
8x Software incompatibility in a
multi-units system
9x Loss of synchronization between
the units
(43) ON This indicator is glowing continuously when the device is working.
It flashes when the equipment is temporarily stopped due to a fault displayed by the indicator (42) or a ON/OFF control
wired at the "Remote ON/OFF" input (7).
The equipment will restart automatically when the conditions that led to the temporary stoppage have
gone away.
In the systems with multiunit's in parallel, the indicator (43) blinks 2 times when the WPC is temporarily stopped by the
master unit of the concerned phase while this mode is authorized. {1547}.
(44) BATTERY CHARGER This indicator is glowing continuously when the charger is working and has not yet reached his
absorption phase.
It flashes twice during the absorption phase and once during the floating phase.
If the Smart Boost mode has been activated, this indicator goes out temporarily when source backup is required by
users (loads).
(45) AC IN This indicator is glowing continuously when an alternative voltage with correct values, either in frequency
{1112-1505-1506}, or in voltage {1199} is present at the AC IN input of the device and the current limit set by the user
has not been reached. It flashes one time when the current limit at the input {1107} set by the user has been reached.
In this case the charger current is reduced in order to guarantee priority supply to the users (see chap. 7.2.5 p. 28). If
the input current is exceeded nevertheless, the WPC goes back to inverter mode (transfer relay open) and the indicator
(42) will keep flashing as long as the user current exceeds the limit value of the input current {1107}.
If the Smart Boost mode (see chapter 7.2.5 – p.28) is used and the inverter is part of the user supply – therefore the

Comment
If the device has not yet stopped, it is recommended to disconnect all non-priority
consumers and/or start up the generator. If the WPC has stopped it will restart
automatically when the battery voltage has reached the correct value again {1110}.
It can be restarted manually using the ON/OFF button (41) as long as the battery
voltage is higher than the critical threshold {1488}. See also chapter 7.2.6 – p. 29.
In this event the equipment will make several attempts restart {1300} every few
seconds and will stop if the overload remains (see chap. 7.2.6 – p. 29). It is vital to
eliminate the cause of the overload without restarting. Restarting is carried out
manually by pressing the button (41).
This may be due to too great a load for the device, at too high an ambient
temperature or counteracted or obstructed ventilation. The power output of the
device will therefore be limited to around 50% of the Pnom. including in charger
mode or Smart Boost mode.
Check the cause of this excess voltage. The equipment will restart automatically
when the voltage falls below the threshold value {1122}.
see chap. 7.2.6 – p. 29
In this case, the WPC remains in operation in inverter mode until the output power
decrease below the input limit and does not allow the transfer relay to close. You
must increase the input current limit {1107}, or authorise the exceeding of this limit
{1436} or authorise backup on the source {1126}, or disconnect some consumers
(decrease of loads).
Voltage is present at the device output. Check your cabling: correct the fault and
start the installation again using a manual control on the button (41).
Check the input protection devices (H) for all the system units.
The software version of all units in the system must be harmonised. Proceed
according to the WPC-RCC/PSCP user manual to upgrade the software.
Failure of the link between the units. Check the presence and the state of the
communication cables between units.
