Time Mark 412SP Automatic Reverse Controller

Description:

The Time Mark Corporation 412SP Automatic Reverse Controller is designed to detect grinder motor jams by sensing overcurrent and automatically reversing motor rotation to clear obstructions before resuming normal operation. Commonly installed on sewage grinder pumps, wastewater lift stations, municipal pumping systems, and industrial pumping equipment where automatic jam clearing improves system reliability. Maintenance teams, OEMs, and system integrators use the 412SP for replacement, repair, retrofit, and preventive maintenance to reduce downtime, minimize manual intervention, and extend grinder pump life.

Applications:

The Time Mark 412SP Automatic Reverse Controller is a current-sensing controller that detects motor jamming conditions and initiates automatic forward and reverse operating cycles to clear obstructions before returning the motor to normal operation. It is widely used in sewage grinder pumps, wastewater treatment facilities, municipal lift stations, industrial pumping systems, and other applications where automatic jam detection and motor reversing improve operational efficiency and reduce maintenance costs.
