Troubleshooting the Pumps/Blower/Ozone
If one or more of the pumps/blower/ozone are non-operational, re-check
that the code settings have been programmed correctly for the equipment
confi guration. If programmed correctly, the main fuses and output voltages
should be checked.
Checking the Main Fuses
On the B7 board, the Circulation Pump, Pump-1, Audio, and ozone all
use the F1 Fuse (Testing Point 4). The Blower, Pump-3, or Pump-2 (Low-
Speed) uses the F2 Fuse (Testing Point 5)., while Pump-2 (Hi-Speed)
uses the F3 Fuse (Testing Point 6). Check the fuse of the non-operational
component by putting one probe of your voltmeter/multi-meter on Line-
2 (Testing Point 2) and the other on the RIGHT fuse clip of the fuse in
question. You should get a voltage reading equal to the control box’s
incoming power voltage (240VAC or 120VAC). Leaving one probe on Line-
2, move the other probe to the LEFT fuse clip. You should again get a
voltage reading equal to the incoming power voltage, if you do not, then
the fuse has blown and needs replacing.
Checking the Output Voltages
The output power pin of each component are located at the top left of the
circuit board (Testing Points 13-17, and 20). To test, activate the desired
component that is being tested. Pump-1, Pump-2, and Aux can be activated
by simply pressing their corresponding button on the topside. The ozonator
is only activated during fi ltration cycles, so you’ll have to force the system
to fi lter to test the ozone power. Activation is not necessary for 24hr Circ
pump or Audio as these components are constantly powered. Next place
one probe of your voltmeter/multi-meter on Line-2 (Testing Point 2), and
the other on the testing point for the component in question. If the fuse
checks out, but no voltage is read on the power terminal of the component
in question (while the control is of course calling for that component to
run), then the relay for that component has failed.
