SmartFOAM
Distribution Box
The Distribution Box (part of the pump/motor assembly)
controls the speed of the pump/motor based on commands
from the SmartFOAM controller display. The distribution box
also receives the signal from the foam feedback sensor, low
tank sensor(s), and tank selector and relays that information
back to the SmartFOAM controller display.
Figure 65 : Distribution Box LEDs
The distribution box contains six internal LEDs to help with
diagnostics (refer to Figure 65
: Distribution Box LEDs ).
❑
TNKA is illuminated when the tank selector is set to
“tank A”. This is based on a physical input into pin 4
of the gray connector on the front of the distribution
box.
(When the TNKA and TNKB LEDs are OFF the
system is in FLUSH mode).
❑
TNKB is illuminated when the tank selector is set to
“tank B”. This is based on a physical input into pin 5
of the gray connector on the front of the distribution
box.
(When the TNKA and TNKB LEDs are OFF the
system is in FLUSH mode).
❑
VCC is illuminated when power and ground are
applied to the distribution box’s pins 1 and 12. This
indicates that the internal 5 volt regulator is
functioning for the internal components.
❑
VIGN is illuminated when power and ground are
applied to the distribution box’s pins 1 and 12. This
indicates that system power and ground are
recognized within the unit.
❑
DPWR
is illuminated when the “IN” power stud is
energized with system voltage. This power is
required to drive the motor attached to the pump.
❑
COM is illuminated when the distribution box is
communicating with the SmartFOAM controller
display via the CAN. This LED with be flashing if
there is a CAN communication problem and it
cannot communicate with the SmartFOAM controller
display.
If no tank selector (MST, MDTII, ADT) is used a connector
plug is installed to connector C8 to lock the system in the
Tank A mode. (See Figure 35
: SmartFOAM Harness
Connections ). Removing this plug or disconnecting the tank
selector cable places the system in the FLUSH mode.
Figure 66: 610-00044 New Distribution Box
The distribution box was upgraded Fall 2017 to 610-00044.
This new distribution box has improved protection against
overcurrent. There are three inputs (green, black, and grey),
but only the grey is utilized for foam units. The black
connector is power. There are three standalone indicator
lights on the top of the case:
❑
SYSTEM PWR is
illuminated when the “IN” power
stud is energized with system voltage. This power is
required to drive the motor attached to the pump.
❑
MOTOR PWR is illuminated when there is power
output to the foam motor.
❑
COM is illuminated when the distribution box is
communicating with the SmartFOAM controller
display via the CAN. This LED with be flashing if
there is a CAN communication problem and it
cannot communicate with the SmartFOAM controller
display.
