5 Faults / Defects
5.1 Remedying faults
5.1.1 Ele ctrical fault
a) Rotary drive not working:

Check:

Is the power cable connected and the external power supply live?

Is the main system switch set to the I setting and is the green control lamp
lit?

Is the control cable with plug connector correctly connected to the control
cabinet?

Are the cables OK?

Has the emergency-stop switch been enabled?
If the welding bench is still not turning, additional troubleshooting must be carried out
by a trained electrician or a service technician!
b) Display of battery discharge
B lights up:

replace battery
If no symbol appears in the display then the battery is in perfect condition. If the ca-
pacity of the batteries has dropped to a low level this is signalised by a continuous
battery symbol. If the capacity of the batteries drops even further after this to below a
certain level then the battery symbol flashes (pulsating). One month before complete
discharge, the display remains switched on or functional.
The electronic position indicator is supplied by 2 x AA standard 1.5 V DC batteries.
Depending on the quality of the batteries, this is sufficient for 1 year of operation (al-
kali type). Discharge of the battery is indicated by a "flashing" in the display. One
month before complete discharge, the display remains switched on or functional.
Responsible: instructed personnel or trained electrician
Before remedying faults, switch off the welding bench
and disconnect from power supply. Make sure that the
welding bench is not accidentally switched back on
when remedying the fault. Appropriate safety measures
must be taken.
