7.1 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

Mains voltage, idle +/– 15 %

Incoming mains voltage may

have fallen below or risen

above the set nominal value.

Check the mains voltage.

Mains voltage, cutting +/– 20

Incoming mains voltage may

have fallen below or risen

above the set nominal value

during ongoing cutting.

Check the mains voltage.

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.
