Install Summing Device
The summing device mounts with two screws. Make sure there is room to connect
the cables and adjust the potentiometers.
Install Cables
Cables need to be connected from the control module to power, to the metering
valve, and to the summing device. The standard AutoFoam has three cables connected
from the summing device to the flow sensors. (Refer to Figure 8.)
1. Connect the control module power cable. A 5' power extension cable is
provided. Connect the extension cable red wire to the truck 12/24 VDC
(positive). Connect the black wire to ground.
2. Connect two (2) foam flow sensors to the summing device with the extension
cables supplied .
3. Connect the discharge flow sensor to the summing device with the extension
cable supplied.
For the multiple discharge flow sensor option, connect all discharge flow
sensors to the discharge flow summing device. The output of the discharge
flow summing device is then connected to the AutoFoam summing device. (If
a flow display is needed, a Y-cable can be used to connect the flow sensor to
both the summing device and a flow display.)
4. Connect the summing device to the control module.
5. Connect the metering valve to the control module.
Perform the Static Operational Check at this time to verify manual operation of
the metering valve. (Refer to Operation section.)
