Circuit Board Command Center:
The control panel is equipped with a circuit board and control command
center. There are two “HOA” switches, a pump selector switch and a Check It
switch. Two green power “on” indicators provide visual indication for the
control and alarm fuses. Fuses must be replaced with 1 amp fast acting 5mm
x 20mm fuses. 4 red level indicators are provided for level indication of the
off, lead, lag and alarm switches.
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.
