SmartFOAM
Pump/Motor
The discharge of the foam pump directs foam to the rotary
lobe flow meter. The rotors are a composite material
containing small stainless steel targets. As the foam is being
pumped these targets are detected by the inductive sensor
which sends pulses to the distribution box. An LED indicator
on the inductive sensor flashes as a target passes the tip of
the sensor. The speed of the foam being pumped
determines how quickly the rotors are turning and how
quickly the inductive sensor’s LED flashes (which could be
so fast that the indicator light actually appears to be
constant).

SmartFOAM Controller Bar Graph
The bar graph on the SmatyFOAM controller display
indicates the system capacity and is a good troubleshooting
tool.
Figure 69 : Bar Graph and Warning Messages
If the SmartFOAM controller display does not see foam
feedback data indicating that foam is being pumped, the bar
graph will increase to 100% (full scale) because the
controller is commanding the pump to turn fast in an attempt
to prime it and achieve the proper foam concentrate flow.
If the display does not receive data that foam concentrate is
flowing, it displays
“ramping to re-gain foam prime” caution
message. This message also displays the number of
seconds until the pump will be turned OFF if prime is not
established.
If the timer times out then the “foam pump shut
down” operation halted message will appear. Pressing ON
button starts the cycle again.
The Total Foam flow display is useful in this scenario to
determine if the foam sensor is detecting any foam flow.
PROBLEM ISOLATION
SmartFOAM replacement parts are
“plug and play” type
devices that do not require specialized equipment to service.
Normal water flow and foam calibration is usually necessary
after a major component service.
The first step in troubleshooting is to determine which
subsystem caused the system failure. To make this
determination operate the apparatus and Hale SmartFOAM
system in accordance with standard operating procedures
and isolate where the problem occurs.
1. Setup the apparatus for normal operation.
2. Power-up the apparatus and energize the pump
operator panel. Take notice of the Hale SmartFOAM
control unit. If the display is NOT illuminated check
for power and ground voltage on the SmartFOAM
controller’s “B” connector.
3. If the Hale SmartFOAM controller is illuminated,
engage the apparatus water pump and establish
discharge. If water flow CANNOT be established,
troubleshoot the water pump system.
4. If there is no indication of water flow on the control
unit display troubleshoot the water flow sensor.
5. If water flow is established, turn the Hale
SmartFOAM system ON to flow foam.
6. Observe foam pump discharge. If foam is NOT
flowing troubleshoot the foam pump.
7. If foam is flowing, check the status of the total foam
flow display. If the foam total is NOT incrementing
troubleshoot the foam flow sensor.
8. If the foam flow is registering on the total foam
display but the accuracy is not correct (too little foam
/ too much foam) check accuracy of system using
calibration procedures in the OPERATION section
of this manual making adjustments as required.
