Time Mark Corporation 412SP Automatic Reverse Controller

The Time Mark Corporation 412SP Automatic Reverse Controller is a current-sensing device that detects grinder motor jams by overcurrent and automatically reverses motor rotation to clear obstructions before returning to normal operation. Designed for sewage grinder pumps, wastewater lift stations, municipal pumping systems, and industrial pumping equipment, it helps reduce downtime and manual intervention by automatically handling jam conditions and resuming forward operation after clearing the obstruction. Key specifications include a 120 VAC supply at 50/60 Hz, monitoring function overcurrent/jam detection, automatic forward/reverse cycling with up to five selectable cycles, and an alarm output that activates when maximum reverse cycles are exceeded; it accepts 10 A at 240 VAC direct or 5 A at 480 VAC direct, with higher currents requiring external current transformers. The controller provides LED status indicators for forward, reverse, and alarm, a manual push-button simulator for testing, adjustable current trip level, surface-mount installation, and compatibility as a replacement for Time Mark 412, 421, and 422 devices.
