INITIAL SYSTEM POWER CHECK
Observe the display on the control unit
while energizing the apparatus electrical
system and turn the foam pump distribution
box power switch to
ON
. Check the control
unit readout —
FLOW, TOTAL FLOW, %
FOAM, TOTAL FOAM, ON
and all bargraph
LEDs will light along with
"88888"
for several
seconds. "
HALE
" will then appear for
several seconds while the system checks
itself followed by the default display. If the
Hale FoamMaster system is installed with a
single flowsensor the default display is zero
on the digital readout (if no water is flowing)
and FLOW LED (See figure 2-33). When the
Hale FoamMaster is installed using multiple
flowsensors and foam discharge
multiplexing display units the default display
is
% FOAM
. If default display does not
appear refer to TROUBLESHOOTING for
possible causes and solutions.
INITIAL SYSTEM OPERATION CHECK
After initial system power-up, low tank level
sensor operation, foam pump operation
and flowsensor calibration must be
checked. Use the following procedures to
complete these system checks.
CAUTION:
Water is used at the system
installer facility to verify low tank level sensor
operation and foam pump operation as the
end user specified foam concentrates may
not be readily available. DO NOT pump
water with the Hale FoamMaster foam
pump for more than one minute per foam
tank. DO NOT attempt to calibrate foam
pump feedback sensor with other than end
user specified foam concentrate. Make
sure the bypass valve is in the BYPASS
position when pumping water with the
foam pump.
When energizing the Hale FoamMaster system at the system installer facility for the first time
the following procedures shall be used.
