Configurable functions
4.5 External device monitoring (EDM)
The external device monitoring (EDM) checks if the contactors actually de-energize when
the protective device responds. If you activate external device monitoring, then the M4000
checks the contactors after each interruption to the light path and prior to machine restart.
The EDM can so identify if one of the contacts has fused, for instance. In this case the
external device monitoring places the system in the safe operational status. The OSSDs
are not re-activated in this case.
The indicators and the operational status after the external device monitoring has
triggered are dependent on the type of error present and the configuration of the internal
restart interlock in the M4000 (see Tab. 12).
