FAQ

What is the primary function of the restart interlock feature?

The restart interlock ensures that the machine cannot automatically restart after a safety event until a deliberate reset action is performed by an authorized operator.

How does external device monitoring (EDM) work in this module?

EDM continuously monitors the state of connected safety outputs, such as contactors, to verify that they open and close correctly during each safety cycle.

What type of diagnostic information does this safety relay provide?

It provides diagnostic outputs indicating the operational status, fault conditions, and safety circuit integrity to facilitate maintenance and troubleshooting.
