SJE-Rhombus Model 322 - Three Phase Duplex Alternating Pump Control Panel Description

Three Phase, Duplex Alternating Pump Control with Override

The Model 322 control panel is designed to control two 208/240/480V three phase pumps in water and sewage installations. The controller is provided with a pump selector switch that can be set to alternate the pumps to equalize wear or to call either pump to activate first with the other pump to activate in lag condition. If an alarm occurs, the alarm activates the audible-visual system. The alarm conditions include: high water, float out-of-sequence, pump fail-to-run, seal failure (optional). Common applications include lift stations, pump chambers and irrigation systems.
