RESTART_FBK
Using the RESTART_FBK signal input, MSC can monitor a feedback loop signal (External
Device Monitoring – EDM) from external contactors; both manual and automatic forms of
starting can be programmed (see list of the possible connections in Table 13).
If necessary, the response time of contactors must be monitored using an additional
device.
The command switch for starting (RESTART) must be installed outside the danger ar-
ea in a place from which there is a clear view of the danger area and the entire work-
ing area affected.
It must not be possible to actuate the command switch from inside the danger area.
