1x
(Imminent) stoppage as a
result of low battery voltage.
If the device has not yet stopped, it is recommended to
disconnect all non-priority consumers and/or start up the
generator. If the Xtender 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 6.2.9 – p. 24.
2x
Stoppage due to overload in
the equipment, due to either
a short-circuit or too high a
load for the inverter.
In this event the equipment will make several attempts restart
{1133} every few seconds and will stop if the overload
remains (see chap. 6.2.9 – p. 24). It is vital to eliminate the
cause of the overload without 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 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.
4x
Battery voltage higher than
the maximum limit set by the
configuration {1121}.
Check the cause of this excess voltage. The equipment will
restart automatically when the voltage falls below the
threshold value {1122}.
see chap. 6.2.9 – p. 24
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}, or authorise the
exceeding of this limit {1436} or authorise backup on the
source {1126}, or disconnect some consumers (decrease of
loads).
6x
Startup 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 on
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
The software version of all units in the system must be
harmonised. Proceed according to the RCC-02/03 user
manual to upgrade the software.
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 cabled at the ”Remote ON/OFF” input (7), or when the equipment is
intentionally put to idle mode by the master unit in a multi-inverter parallel system (see chap.
chap.6.3.2 - p. 26).
The equipment will restart automatically when the conditions that led to the temporary
stoppage have gone away.
In the systems with multiunits 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.
