12.3 (004) INPUT FREQUENCY AC-IN WRONG
The voltage at AC-In does not have a frequency included in the admissible range for the Xtender.
Solution: When operating on a generator, check its speed.
If you are not equiped to measure the generator frequency, measure its voltage with
no load. Indeed, if the voltage is correct, the frequency is generally correct as well.
12.4 (006) INPUT VOLTAGE AC-IN TOO HIGH
The voltage at AC-In is too high for the Xtender and represents a danger for the consumers; the
transfer relay is not activated.
Solution: Reduce the voltage on the AC-In input to come into an admissible range.
12.5 (007) INPUT VOLTAGE AC-IN TOO LOW
The voltage at AC-In is too low for the Xtender. The transfer towards consumers and battery charging
are not activated.
Solution: Reduce the voltage on the AC-In input to enter an admissible range.
Do not increase the voltage of the generator during battery charging or when the
consumers are connected to it: If the consumers stop, an overvoltage may arise
which will destroy components of your installation.
If the transfer towards the consumers is carried out and this message appears a few
seconds after the start of the battery charging, check the configuration of the
maximum current of the source (Input limit) {1107}.
12.6 (008) HALTED: INVERTER OVERLOAD SC
The consumers require more power than the Xtender inverter can supply.
Solution:
Adapt the maximum power output of your consumers to the maximum power output of the
Xtender
Check that the cabling is not short-circuited.
12.7 (014) HALTED: OVER TEMPERATURE EL
The Xtender stops due to overheating.
Solution:
Check that the ventilation holes of the Xtender are not obstructed.
Check that the Xtender is not situated in a place where the ambient temperature is too high.
Adapt the power max. of the users to the nominal power of the Xtender according to the
ambient temperature.
The overtemperature is disadvantageous for the service life of certain electronic
components. If the stoppages due to overtemperature happen frequently,
corrective measures will be required.
