This sub-menu allows you to configure the DLCM to interact with a level input. You can program the
DLCM to have one of the following responses:
− Shut the motor off,
− Trigger the alarm relay,
− Shut the motor off and trigger the alarm relay,
− Shut the motor OFF when the level input is in one state (e.g. CLOSED) and turn the motor ON
when the level input is in the other state (e.g. OPEN).
