Description
The model PCS is a Pump Control Switch with independent set and reset points which are adjustable throughout the entire operating range of the switch. The minimum deadband (minimum span between set and reset points) may be obtained at any point in the operating range of the switch. When the pressure drops below the setting, a snap action switch closes energizing the built in pump control relay and turns the pump on. When the pressure increases above the high setting, the snap action switch opens de-energizing the built in pump control relay and turns the pump off.
