Single phase, duplex alternating pump control with override. <br />The Model 122 control panel is designed to alternately control two 120, 208, or 240 VAC single phase pumps in water and sewage <br />installations. The alternating action equalizes pump wear. In addition to the alternating pump control, this system provides override <br />control should either pump fail. If an alarm condition occurs, an alarm switch activates the audio/visual alarm system. Common <br />applications include pump chambers, sump pump basins, irrigation systems and lift stations. <br />1.
