Installation and Operation Manual
NOTE: ALWAYS REPLACE THE COVER SCREW
AND O-RING TO KEEP WATER AND DIRT FROM
ENTERING THE DIGITAL DISPLAY CONTROL
MODULE BECAUSE IT CAN CAUSE SERIOUS
DAMAGE TO THE COMPONENTS.
The system will provide a full complement of
diagnostic functions to enable verification of all
system components.
DIAGNOSTIC MODE FUNCTIONS
On entry to diagnostic mode, the display will show
“HELLO”. No other status indicator lights will be
illuminated. “SELECT” will select the various modes,
each indicated by the status indicator light by the label.
These diagnostic modes include:
“None”
Pressing will illuminate all display segments and
status indicator lights.
“Flow”
The value shown is the current number of flow
pulses being received each second. If no water is
flowing, the value should be zero. This is a function
test for the flowmeter. Removing the flowmeter
sensor from its tee and spinning the paddlewheel
should produce a reading other than zero on the
display. If there is no reading on the display. Check
the cable for continuity. If good, replace flowmeter.
If not, replace cable.
“Total Water”
The value shown reflects the level of the liquid foam
concentrate in the tank. “Lo.Con” indicates that the
tank is empty. “Hi.Con” indicates a satisfactory level
for operation. This is a test of the low-level sensor
and wiring.
“%” (Percent)
The value shown reflects the duty cycle to run the
foam pump. If “FOAM” is pressed, the pump will
be run at the selected rate and the “ON” status
indicator lamp will be illuminated. The value may
be altered with or . This is a test of the motor
control box and pump hook up. Depressing the
will increase pump speed, which should be
audible and visible on the “TOTAL FOAM” display.
“Total Foam”
The value shown is the current number of pump
pulses being received each second. If the pump is
not running, the value should be zero. Increasing
motor speed in “%” mode should increase displayed
value. This is a test of the pump feedback sensor
and wiring.
