Summing Box (Multiple Flow Sensors Only)
The summing box has two 12-Pin connectors. Each box has inputs
for six (6) discharge ow sensors. Multiple boxes are interconnected using
the FRC datalink. Power is provided by the control model.

from control module.
Note: When more than one box is installed the address
of each box must be set. Refer to Installation Section.
Flow Sensor
Systems with a single discharge ow sensor: The sensor cable is connected directly to the control module.
Systems with multiple ow sensors: The sensor cables are connected to a summing box. The summing box
is connected to the control module via a supply power and FRC datalink cable.

Note: If FRC owmeters (DFA or FPA) are used to retrieve ow rate
information, only the FRC Datalink is connected to the foam system.
IMPORTANT the owmeter ID numbers must be different than the
ow sensor ID numbers used with a summing box.
