8: Ambient temperature more than +50ºC.
The unit has detected that the ambient temperature sensor has broken or a wire has gone
open circuit. The unit must be returned to a service agent for repair.
10: Low supply frequency <40Hz
The unit has detected that the supply frequency is below 40 Hz. This will normally be caused
by a poor quality generator. If this fault happens then check the supply or change the
generator.
11: High supply frequency >70Hz
The unit has detected that the supply frequency is above 70 Hz. This will normally be caused
by a poor quality generator. If this fault happens then check the supply or change the
generator.
12: High supply voltage >140v (or 280v with a 220v supply)
The unit has detected that the supply voltage is more than 140 volts (280 volts with a
nominal 220v supply). Check the supply voltage and if necessary use a different generator.
13: Low supply voltage <95v (or 190v with a 220v supply)
This fault can be caused by a few problems. It could be that the generator is running slowly
and so the supply voltage is low. Try speeding the generator up or use a different generator.
It could also be caused by a generator that is too small. If a large fitting is welded, then a
large amount of power will be needed from the generator. If it can not supply this power
then it will stall and the voltage will drop away. Check that the generator is the correct size, if
needs be try another generator.
It could be caused by the use of long extension leads. If a large fitting is welded then a high
current will be taken from the supply. If extension leads are used, there will be a volts drop
down the lead making the unit sense a low supply voltage. Try not to use extension leads
with the unit. If you have to then use just 10 meters of 4.0mm2 cable, the same size fitted to
the unit.
14: Relay failed to latch on weld start
This fault could happen when the start button is pressed. If the main power relays do not
operate correctly then this fault will be shown. The unit needs to be returned for service.
20: Low output volts (-1.25%)
This fault will happen if the output voltage is 1.25% lower than the set point for more than
3 seconds. This can be caused by a generator that is not big enough to supply the required
power to the fitting. Check the size of the generator and if needs be try another generator. It
can also be caused by using long extension leads with the unit. It is recommended that only
10 meters of extension are used, and the cable should be the same thickness as the input
lead on the unit (4.0mm2).
