SJE Rhombus Duplex Alternating Board Test

Pumps do not alternate. Applicable for models 122, 123, 124, 322, and 324. Images may vary depending on the panel and features.

WARNING: Please use caution while handling your pump control panel. We have designed them with the highest safety standards in mind, however they are complex electronics and can cause death or serious injury if used improperly. Only follow the instructions provided in these videos and contact our support team if you are unsure of what to do.

Do both contactors operate (pull in) on hand mode (aka manual operation)?

Disconnect all power to the panel or turn the Control On/Off switch to the Off position if applicable.

Switch the HOA switches to the Auto position.

Tag the floats and remove them from the terminal block in the panel.

Place a jumper wire between positions 3 and 4 of the Stop circuit.

Reconnect power to the panel.

Turn the Control On/Off switch to the On position. Two things should happen: 1) one of the pumps should start, and 2) the stop and start float LED's should illuminate. Some panels have Pump Run indicator lights. Did these both happen?

Turn the Control On/Off switch to the Off position.

Reapply power to the panel or turn the Control On/Off switch to the On position. Two things should happen: 1) the other pump should start, and 2) the stop and start float LED's should illuminate. Some panels have Pump Run indicator lights. Did these happen?
