arg
Message of an external temperature input: - cable between
thermostatic switch and timer interrupted - insufficient cooling
- excessive welding heat/%I / duty cycle
Recommended actions
check cable/connector - check cooling circuit - reduce welding
heat.
110708, Stop circuit open, no +24V.
Description
Task:arg
arg
+24V supply at stop circuit input missing.
Recommended actions
Close stop contact - check +24V supply at the inputs of the stop
circuit.
110709, Circuit breaker tripped, weld without
command.
Description
Task:arg
arg
The timer module has activated the main switch relay: the
related main switch/circuit breaker is tripped.
Recommended actions
-
110710, Current feedback open.
Description
Task:arg
arg
Broken sensor cable - detached plug connections - incorrect
connector assignment - defective sensor.
Recommended actions
Replace cable - check plug-in connections - check connector
assignment - replace sensor.
110711, Current feedback short circuit.
Description
Task:arg
arg
Squeezed sensor cable - incorrect connector assignment -
defective sensor.
Operating manual - Troubleshooting IRC5
3HAC020738-001 Revision: AA
Recommended actions
Replace cable - check connector assignment - replace sensor.
110712, No primary voltage on first half wave.
Description
Task:arg
arg
No primary voltage was measured in KUR mode.
Recommended actions
Check connectors and cables.
110713, No current, weld 1 to 3.
Description
Task:arg
arg
Electrodes not closed - no electrical contact at the point to be
welded - contamination of sheets - use of sealant.
Recommended actions
Check closing mechanisms (robot, machine) - check position
and pressure of electrodes - clean sheets - check conductivity.
110714, Current is too low, weld 1 to 3.
Description
Task:arg
arg
Current measured is below tolerance band: - tolerance band
too narrow - programmed value too high, e.g., because of
stepping - contamination of electrodes - contamination of sheets
- bad electrode positioning - welding transformer too small.
Recommended actions
Check tolerance band - check programmed value, stepper
values - repeat weld, clean electrodes - repeat weld, clean
sheets - improve positioning - change over or replace welding
transformer.
110715, Current is too high, weld 1 to 3.
Description
Task:arg
arg
Current measured exceeds tolerance band: - programmed value
jump to lower current values - handling of different sheet
thicknesses or sheet layers - variant electrode pressure
conditions - variant resistances (impedance) in secondary
circuit, e.g. shunt resistor - mains voltage fluctuations.
