SD module
You can select from the following settings for the individual monitoring
channels:
"Off" Monitoring channel is deactivated.
"Message
group 1”
or "2" The welding power source sends a message to a master con-
troller for further processing. The master controller makes
the decision (PLC, robot).
"Abortion
group 1”
or "2" The welding power source immediately stops welding. The
welding power source sends a message to a master control-
ler for further processing.
In both cases, the OMI module or a bus system set digital outputs which
can be further processed via peripheral equipment (special purpose ma-
chines, carriages or PLC) or a robot controller in a process-related manner.
• Set value
The value specifies the expected actual value.
• Warning range
The value, e.g. ± 5 A, indicates the section from the warning range to the
limit range where a warning message is displayed in the operating mod-
ule.
• Limit range
The value, e.g. ± 10 A, indicates the range in which an error message is
triggered or welding is aborted, depending of the setting.
• Start delay
Via the start delay, the monitoring can shortly be deactivated between
0.0 to 99.9 seconds from the time of the monitoring start or after each list
change. This is recommended during the ignition and stabilisation phase
of the arc to avoid that the monitoring generates unnecessary error mes-
sages.
• Error time
An error must be existing at least for the duration of the programmed er-
ror time in order to be reported as error by the monitoring. The error time
can be selected between 0.0 and 99.9 seconds.
