Figure W3. Foam Pump Control Wiring
Foam Pump Control
The foam pump control is a part of the foam pump assembly. The box houses the electronics that control the
motor. The power for the electronics is provided over the four wire cable from the control module. Motor power
is provided over separate DC supply cables. Refer to table for recommended wire size.
The rubber terminal covers for the DC supply power should be installed with the opening down to prevent
water from collecting in the cap.
Note: The rubber terminal covers should be installed
with the opening down to prevent water from collecting
in the cap. Ensure that the rib on the cap snaps into the
groove in the terminal.

Notes:
- Supply power for electronics is provided by the control module.
- Pins 5-9 are used when the electric ush valve is installed.
- Pin 10 outputs +DC voltage when the foam concentrate pump
is operating. It is capable of driving a 3 amp load.
The output from pin 10 is commonly used to open a CAFS
valve. (No output during ush operations.)
