MC Features ContinuedMC Features Continued Restart Time Delay

Controllers utilize a re-start timer to delay the

instantaneous re-start of the controller. This allows

electromagnetic fields in the motor to decay.

Model MCP

Controllers will continue to operate if

the voltage drops by as much as 35% of rated voltage. This can be critical when starting

the fire pump on emergency power.
