EDM

Contactors outside the safety light grid

 

can be monitored (External Device Monitoring =

EDM, also known as feedback loop monitoring).
EDM only needs to be activated if the contactors are controlled directly.
A test is performed to see that the N/C contacts switch if the state of the OSSD changes
and so is used to monitor and detect malfunctions on the contactors. If a malfunction is de-
tected, the safety light grid switches

 

to a safe condition and stops the connected machine.

This check is carried out each time the OSSD is triggered and before restarting.
