7.2.12 Motor Thermostat Set Up

This sub-menu allows you to configure the DLCM to interact with the pump motor thermostat.
Depending on the application, it is possible for the fan cooled pump motor to run at low RPM and high
torque, which degrades the effectiveness of the fan and can cause heat build up.

For equipment safety, the DLCM can be programmed to have one of the following responses if the
Motor Thermostat activates:

−

Shut the motor off, (no alarm) (no restart)

−

Trigger the alarm relay, (motor stays on)

−

Shut the motor off and trigger the alarm relay, (no restart)

−

Shut the motor off, trigger the alarm relay, and then restart the motor when the Motor Thermostat
resets,

−

Shut the motor off and then restart the motor when the Motor Thermostat resets (No alarm),

−

Ignore the thermostat input. (not recommended)
