SERVICE AND TROUBLESHOOTING
04
Error in ext. input
If device connected to external error input triggered the error.
If a device is not connected to the external error input:
X
Deactivate monitoring function in the system settings.
05
Current fault
Used in connection with a deviation of the weld current.
Example: "Warning: Low current fault", see message 01
06
Current abort
The weld current has overshot or undershot the limits defined for aborting in the
monitoring limits and the process was interrupted.
X
Check limit values: Possibly set too close together.
Excessive resistance in weld circuit (ground connection, rotor, current water cable):
The machine can no longer keep the programmed weld current (setpoint value) stable
within the specified limits.
07
Low
The limit value set for the low pulse of the corresponding parameter was reached;
see also message 01.
08
Voltage
The message appears as "Warning: Voltage". The limit values specified in the
monitoring limits for the alarm were overshot or undershot.
X
Check limit values and heed information in "Monitoring functions"
see Sec. 8.9, Page 50.
Cause for excessive arc voltage:
•
High transition resistances in weld circuit (plug, ground contact etc.)
For cassette heads: Worn current water cable.
09
Voltage abort
The limit values for aborting with regard to arc voltage specified in the monitoring
limits are overshot or undershot.
X
Check limit values and heed information in "Monitoring functions"
see Sec. 8.9, Page 50.
Cause for excessive arc voltage:
•
High transition resistances in weld circuit (plug, ground contact etc.)
For cassette heads: Worn current water cables.
10
Speed
Supplement to "Warning". The limit values specified in the monitoring limits (warning)
of the speed were overshot or undershot.
X
Check limit values.
X
Check weld head speed.
X
Carry out motor calibration if necessary.
11
Speed abort
The weld speed has overshot or undershot the limit values specified for abortion in
the monitoring limits and the process was aborted.
Check limit values; they may be too close together.
Possible causes for speed aborting:
Mechanically blocked, jamming or defective weld heads
X
Check whether the weld head can be moved manually (or with the remote control).
X
Carry out motor calibration if necessary.
12
Time limit for high-
voltage ignition
exceeded
After the ignition device was switched on, an arc was not ignited within approx. 3
seconds. The process is interrupted.
Causes for failed arc ignition:
•
Fault in marginal conditions of the process, e.g. forgotten ground connection
see Sec. 9.2.5, Page 63.
13
Inverter
Fault in serial communication (RS232) between PC controller and inverter.
X
Switch machine off and then, after 30 seconds, switch it on again.
Is the fault still occurring?
X
Contact your specialist dealer or ORBIMATIC.
