Error Codes; Maintenance - Cebora 553 Manuel D'instructions

The anomalies checked are as follows; the presence of these anomalies is indicated on the display by Err. 76.
three-phase welding machines:
− the neutral conductor is connected instead of a phase conductor.
− no phase conductor is connected.
− -the supply voltage value is outside the permitted range.
single-phase welders:
− -the supply voltage value is outside the permitted range.
During welding machine operation, if the control logic supply voltage deviates from the permitted range, the operation
of the welding machine is inhibited.
For control logic power supply voltages lower than the permitted limit, the message Err. 14-1 appears on the display.
For control logic power supply voltages higher than the permitted limit, the message Err. 14-2 appears on the display.
Cooling unit, only for Item No 555 and 557.
When the cooling unit mode is set to "ON" or "AUTO", the pressure sensor cuts in inside the cooling circuit to stop the
welding machine from working after 30 seconds. The display shows the message Err. 75 and the flashing message
H2O.
Pressure sensor cut-in can be caused by a lack of coolant.

voltage not as
Fix
Shut off the welding machine and check the supply voltage.
If the problem continues, contact the CEBORA assistance
service.
Shut off the welding machine and check the supply voltage.
If the problem continues, contact the CEBORA assistance
service.
Shut the welding machine off and turn it back on. If
the problem persists, contact the CEBORA Service
Department.
Shut the welding machine off and turn it back on. If the
problem continues, contact the CEBORA assistance
service.
In these conditions, the machine can only be used in DC
welding mode.
Release the start button
per Check the supply voltage. If the problem continues, contact
the CEBORA assistance service.
Wait until the power source cools
Check tank level, connection and cooling unit operation.
Select MENU and check the intervention voltage that has
been set.
Select MENU and check the intervention voltage that has
