Troubleshooting; Technical Data - Fronius TRANSPOCKET 1400 MV Serviceanleitung

TROUBLESHOOTING

Warning! Before opening up the welding machine, switch it off, unplug it from the mains and put up a warning sign to stop anybody inadvertently
switching it back on again. If necessary, discharge the electrolytic capacitors.
Error
Temperatur-LED is constantly lit up
"ON-LED" does not light up
Temperature LED is flashing
Mains fuse / automatic circuit breaker is
tripped (during welding)

TECHNICAL DATA

Warning! If the machine is designed to run on a special voltage, the
Technical Data shown on the rating plate apply. The mains plug and
mains supply lead, and their fuse protection, must be dimensioned
accordingly.

1) Value valid for mains voltage 115 V~
Cause
max. temperature limit has been exceeded (unit is
overloaded)
temperature sensor not correctly connected
temperature sensor is defective
problem with mains voltage
Varistor-power supply module is faulty.
Reason: Input voltage was greater than 270V.
Ensure that unit cannot be switched on again, as
when the varistor is defective there is no longer any
protection against overvoltage.
PFU 14 defective
module defective
secondary diode (V1) defective
PFU 14 board defective
mains fuse protection is too weak, or wrong circuit

Remedy
leave machine to cool while switched on (i.e.
with fan running)
check temperature-sensor plug
replace the temperature sensor
check
install new varistor.
connect unit up to correct power supply
(230 ± 15%)
change PFU 14
change module
replace diode
change board
check the fuse (16A slow-blow) use 2.5 mm
electrode where necessary
