operator when the system is operating. A
function is selected by pressing the grey
“SELECT” button in the upper right hand corner
of the Digital Display Control Module. Each
time the button is pressed, a new function mode
is selected and displayed. A LED lamp above
the digital display denotes which function is
being displayed. Pressing the SELECT button
changes the value displayed but does not alter
system operation.
The Display Functions include:
Flow
The display shows the current flow rate of
water or foam solution per minute.
Total Water
The display shows the total amounts of
water or foam solution pumped. This
totalized value may be reset. See "Reset
Functions" paragraph.
% (Percent)
The display will show the foam concentrate
injection rate setting in the % mode.
Total Foam
The display shows the total amount of foam
concentrate pumped. The value will be in
the same unit of measure as the water flow.
This totalized value may be reset. See
"Reset Functions" paragraph.
RESET FUNCTIONS
The totalized values for water and foam
concentrate pumped can be cleared from
memory by performing a RESET function.
Using the “SELECT” button, select either
“TOTAL WATER” or “TOTAL FOAM”. By
pressing and holding both the and
buttons at the same time, the value shown is
cleared and displayed as zero.
FOAM PERCENTAGE (%)
When the concentrate percentage (%) is
selected, the and buttons will respectively
increase or decrease foam concentrate
percentage. The percentage can be changed
anytime during normal operation. Whenever the
or buttons are momentarily pressed, the
display will switch to the “%” display and show
the current percentage that is set, in any display
mode. If either button is held down for a period
of 2 seconds, the value will increase or
decrease accordingly. Once released, the
display will return to the last selected display.
When a reset is performed in the % display
mode (pressing both the and buttons at
the same time) the foam concentrate injection
rate is returned to the default value. The default
value is set during calibration.
DISPLAY MESSAGES
Several safety features are provided to protect
the foam concentrate pump and the electric
motor.
Low Foam Tank Level
The pump is interlocked with the foam
concentrate tank level switch. If the tank is
empty, the pump will not run for more than
2 minutes. A low foam concentrate tank level is
denoted by “Lo Con” blinking on the display.
This code will alternate with the normal display
value shown. If two consecutive minutes of low
concentrate level is detected, the display will
show “No Con”, the pump will stop, and the
system will go to Stand By mode until the foam
level is restored and the on button is depressed.
Pump Error
Motor stall protection is provided. In the event
that the pump motor will not run or stalls for
10 seconds, the display will show “ERR.EL” to
indicate that the pump is producing no feedback
to the control signal. The system will return to
off status to protect the electric motor and
components.
High/Low Flow Condition
Whenever the foam pump cannot reach the
selected level an indication of the status will
blink in the background as:
“Lo.Flo” – Foam delivery rate is below pump
capability.
“Hi.Flo” – The water delivery rate is too high for
the foam pump's capacity.
