Fault codes
Should a fault condition exist in normal operation, the display will show a code
number. All fault signals will remain on for a minimum of 10 seconds. If the fault is
cleared, all will reset automatically except for over-current. To clear over-current, the
power must be shut off for 5 seconds and then turned back on.
Code Problem
Cause
Solution
1
Mains voltage, idle +/
–
15 %
Incoming mains voltage may
have fallen below or risen
above the set nominal value.
Check the mains voltage.
2
Mains voltage, c/
–
20
%
Incoming mains voltage may
have fallen below or risen
above the set nominal value
during ongoing cutting.
Check the mains voltage.
3
Operating pre-tensioning, +/
–
15 V pre-tensioning
distribution
The operating circuit
transformer does not supply
the correct voltage to the
operating circuits.
Check the transformer and
control board.
4
Thermal switches
Thermal switches off
–
equipment overheated.
Let the equipment cool.
Check that the ventilation is
adequate.
5
Pressure
The air pressure is outside
the permitted interval., min
5.1 bar and max 6.5 bar.
Check the supply
compressed air and pressure
setting.
6
The arc does not strike.
Arc transfer could not occur.
Check the ground lead.
7
Pilot arc time limit (approx 5
seconds) exceeded.
The cutting process did not
begin with the 5 second limit.
Start within 5 seconds:
8
Torch fault
The electrode touches the
nozzle (cannot separate).
Check/replace consumables.
10
Reconnection problem.
The problem primarily occurs
if the hall sensor is not
connected.
Check the cable connection
between the current sensor
board and the control board.
Check the torch for a short
circuit between the nozzle
and the work piece.
Remove any scrap from the
front section of the torch.
11
Over current on the primary
side.
Converter fault.
Send the unit to the
authorised service workshop
for repair.
12
Phase drop, switch off, on
the primary side (mains
supply)
Exceeded single phase duty
cycle rating
Check the mains power
supply fuses.
13
Open circuit voltage fault
Neither voltage nor current
could be detected at
automatic Parts In Place
(PIP) check of consumables.
Send the unit to the
authorised service workshop
for repair.
14
Overtemperature in the
apparatus sheath.
The temperature is higher
than the permitted
operational limit.
Check the ventilation around
the unit.
Check the cooling air gaps
and ensure that any
obstacles are removed from
there.
