7.2.7 Level / Remote / Start – Stop Set Up
This sub-menu allows you to configure the DLC to interact with a level input. You can program the
DLC 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).
The level sensor or Start/Stop switch must be a dry contacting type. Refer to Section 5-Installation:
Low Voltage Input Connections.
If you select the 'motor off' option, the motor will have to be manually re-started when a Level
Failure is detected (i.e., press [MOTOR] to start the pump motor).
