Display options
An alarm message is generated in one of two ways:
• Output via collective indication output (relay) on the module (see chapter 10.2)
• Output of the individual channels via the field bus data with the following assignments:
Bit no.
Parameter
0 Welding
voltage
1 Welding
current
2 Wire-feed
speed
3
Max. motor current exceeded
The relay output is set immediately when one of the monitoring parameters exceeds its tolerance
range. The relay is equipped with a reset delay, it is only shut down if no error has been indicated
for approx. 0.5s.
5.7.3
Monitoring parameters
The following signal specifications can be defined within a JOB:
Parameter Range
specification
Voltage tolerance
Specify in the range 0% to 50% of the nominal value
Current tolerance
Specify in the range 0% to 50% of the nominal value
WF tolerance
Specify in the range 0% to 50% of the nominal value
Maximum motor current
Specify in the range 0 to 5.0A
A response time is assigned to the parameters for voltage tolerance/current tolerance and WF
tolerance/max. motor current; this common response time can be set in the range 10ms to 20s in 10ms
increments.
