The CP-5 is an undercurrent monitor designed to monitor one leg of a 3-phase system. It is commonly used as a tower monitor on center pivot irrigation systems to detect stalled or jammed towers to prevent over watering.

The CP-5 has both an adjustable trip level and an adjustable trip delay timer. When the current is sensed, the Model CP-5 activates its output relay, thus starting the motor/pump. When the current in the monitored power line falls below the userselectable trip point, the unit goes through a trip delay timer and then deactivates the output relay if the monitored current does not recover first.
