1x
(Imminent) stoppage due
to a too low battery
voltage.
If the inverter has not yet stopped, it is recommended to
disconnect all non-priority loads and/or start up the generator. If
the inverter 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 1,5V/cell. The charger
remains functional as long as the battery voltage remains higher
than 1,5V/cell. See also sect. 7.4 – p. 30.
2x
Stoppage due to
overload in the
equipment, due to either
a short-circuit or too high
load for the inverter.
In this event, the equipment will attempt to restart 3 times within
a few seconds and will stop if the overload remains (see sect.
7.4.1 – p. 30). It is vital to eliminate the cause of the overload
before restarting. Restarting is carried out manually by pressing
the button (41).
3x
Decrease in the rated
output of the device due
to a too high internal
temperature.
This may be due to overload of the device, too high ambient
temperature 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.
4x
Battery voltage higher
than the maximum limit
set by the parameter
{1121}.
Check the cause of this excess voltage. The equipment will
restart automatically when the voltage falls below the threshold
value {1122}.
See sect. 7.4.2 – p. 30.
5x
No transfer. Insufficient
power from the source
In this case, the Xtender 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}, authorise exceeding this limit {1436}, authorise
backup on the source {1126}, or disconnect some consumers
(decrease of loads).
6x
Start-up prevented due to
unwanted voltage at the
device output.
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).
7x
Indicates missing voltage
in one of the units of the
system in a multi-unit
configuration.
Check the input protection devices (H) for all the system units.
8x
Software incompatibility
in a multi-units system
Error in a multi-Xtender system. The LED 43 gives further
information:
3x: Communication protocol error or
4x: Software incompatibility
The software version of all units in the system must be the same.
Proceed according to the RCC-02/-03 user manual to upgrade
the software.
5x: communication loss or functional error: check the
terminations on the communication bus and make a reset of the
system {1468}
9x
Loss of synchronization
between the units
Failure of the link between the units. Check the presence and
the state of the communication cables between units.
(
43)
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 entry ("Remote ON/OFF") (7), or when the equipment is put
to idle mode by the master unit in a multi-inverter parallel system (see sect. 8.2 - p. 34).
The equipment will restart automatically when the conditions that led to the temporary
stoppage have gone away.
In the systems with multi-units in parallel, the indicator (43) blinks 2 times when the Xtender is
temporarily stopped by the master unit of the concerned phase while this mode is authorized. {1547}.
