Figure 7: Control Switch Wiring Connection
Two Control Switch Operation
(Remove the factory default jumper located behind the control inputs)
The Fhoton™ Drive is designed to utilize up to two control switches for operation. When both switches are installed, the controller starts
to pump and waits to shut off until both switches read "OPEN". Once it shuts off, the controller then waits to run again until both switches
read "CLOSED". An example application (Figure 8) is to use separate level switches to indicate high and low water levels. When using two
switch inputs, remove the jumper located immediately behind these switch inputs.
One Control Switch Operation
(Leave the factory default jumper inplace located behind the control inputs)
Alternatively, the Fhoton™ Drive may be configured to control water level by using a single input switch. Once properly configured for a
single active input with a control switch installed, the controller starts to pump and waits to shut off until the active switch reads "OPEN".
Once it shuts off, the controller then waits to run again until the switch reads "CLOSED". An example application (Figure 8) would be to use
a single-contact level-switch that keeps the storage tank as full as possible without overflowing. For single level switch control, use only
the "RUN" terminal connections. Leave the jumper in place, located immediately behind these switch inputs.
Zero Control Switch Operation
Lastly, the Fhoton™ Drive may be configured to not use a control switch. In this configuration the Fhoton™ Drive will always try to run the
motor and pump water as long as there is sufficient power from the solar array, leave the jumper in place, located immediately behind
these switch inputs and connect a shorting wire in place of the "RUN" input.
