ERROR MANAGEMENT
Various elements may produce errors. They can be split into 4 categories :
1/ Warning messages designed to warn the operator of overheating, lack of pressure or power, etc.
These messages are displayed on the screen and remain visible until a button is pressed.
2/ The faults that occur in relation to insufficient air pressure or power supply.
3/ The serious faults that block the machine. In this case, contact the service department
4/ The thermal protection is linked by a thermistance on the diode bridge and when it activates the
machine is locked and the message «overheating» is displayed.
Low battery
The message «Battery low» is displayed when the machine is switched on and it indicates that the
battery on the command board is low. This battery is used to record the date and time when the
machine is switched off.
Invalid tool
The message «Invalid tool» is displayed when the machine is switched on and indicates that a button
is pushed in, the trigger is pushed in or a permanent short-circuit. Check the trigger or the buttons on
the clamps to remove the message.
Invalid arm
The arm used is not compatible with the welding mode selected.
Current too low
1/ Check the weld
If the current obtained during a spot weld is lower than the expected value (6%), the machine dis-
plays the warning message «Low current, check the weld».
2/ Check the sheets
If the machine cannot deliver the current required, the error message «Low current, check the
sheets» is displayed. The weld does not happen and the fault must be skipped for the weld to happen.
Insufficient air pressure
If the input pressure is insufficient to deliver the tightening requested,
the machine beeps and displays, before the weld, the error message
«Insufficient air pressure».
Pressing the trigger a second time is used to «force» the spot weld
using the available pressure. If the tightening recorded is insufficient,
the machine displays «Low pressure».
«p low» is also recorded in the active report.
