5.0 WARNING MESSAGES
5.1 INFORMATION MESSAGES
Programme version number
Recognizing of a 230V main power supply
Voltage overshoot. The voltage is higher than the
mains 253V.
Voltage too low. The voltage is less than the mains
207V.
Recognizing of a 400V main power supply.
Voltage overshoot. The voltage is higher than the
mains 440V.
Voltage too low. The voltage is less than the mains
360V.
Air pressure too low. The pressure is less than 4
Bars.
Duty cycle overun. The set is in its cooling phase.
This message will dissappear when the power source has cooled
sufficiently.
5.2 SAFETY MESSAGES

250V for more than one second.
The electrode and nozzle are short-circuited dur-
ing the striking or cutting phases.

WARNING MESSAGES
POSSIBLE CAUSES
- Supply cable broken
- Fuses on the cards faulty
- Torch cable broken
- Trigger connections open circuit
- Power too low
- Mains voltage outside tolerances:
360 V < mains U > 440 V
207 V < mains U > 253 V
- Duty cycle exceeded, unit overload
- Insufficient cooling air
- Fan not turning
- Lack of pressure
- Damaged air pipe
- Torch tip wrongly positioned
- Torch connection damaged
- Unit not reset
- Worn electrode / Nozzle
- No compressed air at the end of the torch
The air -cooling system is out of order.
The main power supply isn't recognized by the
generator.
Plastron removed.
Inverter fault, please call in a technician.
I2C memory dialogue fault, please call in a techni-
cian
Front panel fault, please call in a technician
The power source stops automatically for safety reasons.
6.0 MAINTENANCE
CAUTION: DISCONNECT THE EQUIPMENT FROM THE ELEC-
TRICITY MAINS BEFORE DOING ANY MAINTENANCE WORK.
6.1 MAINTENANCE OF THE EQUIPMENT
Twice a year, depending on the degree of use of the unit, inspect:
- The cleanliness of the equipment
- The electrical and gas connections
- The air filter-regulator.
For all operations:
- Remove the equipment cover.
- Remove the screws from the cover .
6.2 DIAGNOSIS CHART
SERVICING OPERATIONS CARRIED OUT ON ELECTRIC IN-
STALLATIONS MUST BE PERFORMED BY PERSONS QUALI-
F I E D T O D O T H I S K I N D O F W O R K ( S E E S A F E T Y
RECOMMENDATIONS SECTION).
CHECKS AND REMEDIES
Check:
- Mains voltage before and after the on/off switch
- Check the supply violtages on the card
- Check the connections
- Check the electrode / nozzle short circuit without air
- Check the presence of an air supply when the trigger is pressed.
- Check the mains voltage
- Connect the unit to another socket
- Wait for the cooling phase. The unit starts again automatically
- Make sure the front and back of the power source are free of obstacles
- Check that P>4,2 Bars
- Increase the air pressure if necessary
- Check the condition of the air pipe
- Check the torch tip position
- Check the the torch tip connections on the cycle card
- Replace the wearing parts
- Check the air circuit
