1 Phase Duplex

Operation, Maintenance and Installation Manual

HOA switch

Placing the HOA switch in "H" (hand mode) will activate the pump. In the "O" (off) mode the

pump will not activate. Placing the switch in "A" (automatic) mode, will activate the pump

with the level switches. Place the switch in "A" mode when installation is complete and normal

operation is desired.

Pump selector switch

Placing the switch in "ALT" will allow the panel to automatically alternate the pumps on

successive cycles. If a pump needs to be taken out of service, place the switch to the pump

that will remain in service. I.E. if pump 2 is out of service, place the switch to "P1" so the panel

will activate pump 1 on each cycle. Note: If the level reaches the lag/alarm or alarm switch

level the alarm will activate. For applications where alternation is not desired and a lag pump

operation is required, consult factory for further information. When a pump is selected with

the pump selector switch only that pump will activate (simplex mode).

Check It switch:

Use the Check It switch to verify panel operation and ﬂoat status. To check panel operation

place the pump selector switch to "Alt" and the HOA switches to "A". Press and hold the Check

It switch – one pump should activate. De-Press the Check It switch and Re-Press again and the

other pump should activate. The panel will alternate the pumps each time the Check It switch

is pressed.

Use the Check It switch to verify ﬂoat status. In normal operation the ﬂoat status LED's activate when the

level switch "closes". If the ﬂoats are activated out of sequence (I.E., "off" ﬂoat is not activated but the

"lead" ﬂoat is activated) the LED for the "lead" switch will not illuminate. Use the Check It switch to deter-

mine exact status of each ﬂoat. When the Check It switch is pressed and held, the circuit will automatically

give true indication of which level switches are "closed" or "opened". You can perform this test with the

"HOA" switch in either the "O" (off) or "A" (auto) modes.
