Auto Filter Board Filter Circuits: Refer to Figure 7. Verify the auto filter board has DC voltage by checking for the flashing green led (LED7). If the
LED is not flashing, then no DC power is present.
•
Pump Run Relay (Relay board above filter pump only):
1. To test the operation of the pump run relay, you need to perform a resistance check as this relay receives power input from the
connector rather than the auto filter board.
a. Remove the J127 connector.
b. On the controller, press and hold the filter key until “ ” is displayed. Then press the “ L ” key and
“ ” will be displayed. At this point, pressing the “6” key will turn the pump run relay on and
pressing the “6” key again will turn the pump run relay off.
c. Using a multimeter set to ohms, ohm out pin one and two on J127 directly on the relay board. With the LED above the
relay off, the multimeter will display
“ O.L. ” or “ OPEN ”.
d. Press the “6” key on the controller to activate the pump run relay and turn on the LED above the relay. The multimeter
should display 0.5 Ω or less.
e. Turn the controller off and then plug in J127 when finished testing the relay.
•
Divert Actuator Relay (Relay board above filter pump only):

To test the operation of the Divert Actuator Relay, turn off the filter motor circuit breaker then locate J127. With a multimeter set
to DC Volts, place the meter
’ s positive lead in the white wire connector and the negative lead in the yellow wire connector.

With the LED above the divert actuator relay off, the meter should display a positive 24VDC.

On the controller, press and hold the filter key until “ ” is displayed. Then press the “2” key and “
” will be displayed. At this point, pressing and holding the “6” key will turn on the divert actuator relay, return relay and
pump run relay. The meter display will change to negative 24VDC. Release the “6” key to turn off the pump run relay, close the
return valve and place the divert actuator back into the home position. Turn on the filter motor circuit breaker.
•
Return Actuator Relay:

To test the operation of the Return Actuator Relay, turn off the filter motor circuit breaker then locate J127. With a multimeter set
to DC Volts, place the meter
’ s positive lead in the light blue wire connector and the negative lead in the brown wire connector.

With the LED above the return actuator relay off, the meter should display a positive 24VDC.

On the controller, press and hold the filter key until “ ” is displayed. Then press the “ L ” key and “
” will be displayed. At this point, pressing the “6” key will turn on the return relay and pump run relay. The meter
display will change to negative 24VDC. Release the “6” key to turn off the pump run relay and close the return valve.
•
Drain Valve Relay: DRAIN THE TANK OF ALL LIQUIDS OR MAKE SURE THE FILTER PAN IS IN PLACE AND EMPTY BEFORE TESTING THE DRAIN
VALVE

To test the operation of the Drain Actuator Relay, locate J138. With a multimeter set to DC Volts, place the meter ’ s positive lead in
the red wire connector and the negative lead in the black wire connector.

With the LED above the drain actuator relay off, the meter should display a positive 24VDC.

On the controller, press and hold the filter key until “ ” is displayed. Then press the “1” key and “
” will be displayed. At this point, pressing the “6” key will turn on the drain relay and open the drain valve. The meter
display will change to negative 24VDC. Press the “6” key again to turn off the drain actuator relay and close the drain valve.
