USER CALIBRATION
The complete Hale FoamMaster System;
foam pump and motor assembly, control
unit and flowsensor, is tested and calibrated
at the factory before shipping to the
installer. Each component of the matched
system is assigned the same serial number
to ensure they remain together. If the Hale
FoamMaster system is properly installed,
further calibration WILL NOT be necessary
until delivery to customer. The system is
designed to permit easy checking of
component calibration to assure accurate
operation. The calibration verification
process will verify component calibration
and allow adjustments to the flowsensor(s)
and feedback sensor display readings to
allow for variations in apparatus piping
configuration and end user selected foam
concentrate(s). Default values for
simulated flow and foam concentrate
injection rates can be set to end user
specifications while in the calibration mode.
NOTE:
The Hale FoamMaster system is
calibrated at the factory to U.S.
measurement (GPM, PSI, GALLONS, etc.)
units. The system may be calibrated to
any unit of measure, i.e. U.S., Metric,
Imperial, etc. The same unit of
measurement must be used throughout
the calibration process to ensure proper
proportioning by the system.
Recalibration of the system should be
required ONLY after major repairs or
component changes to the Hale
FoamMaster foam system or if different
viscosity foam concentrates are used.
SYSTEM USER CALIBRATION MODE
System user calibration is accomplished by
using the control unit function buttons.
To enter system user calibration mode press
and hold the
SELECT DISPLAY
button, then
simultaneously press and release the
é
and
ê
buttons. The display will show “
CALIb”
(See figure 3-3) for several seconds followed
by "
C
0" and
FLOW
LED. (See figure 3-4)
To exit system user calibration mode and
lock the settings press and hold the
SELECT
DISPLAY
button, then simultaneously press
and release the
é
and
ê
buttons. The word
“
HALE” will appear for several seconds
followed by the default display.
FACTORY DEFAULT VALUES
During calibration it may be desired to
return the simulated flow rate or
concentrate injection rate(s) to the original
factory default settings. To return to the
factory default values enter system user
calibration mode as previously described.
While calibrating the particular item simply
depress the
é
and
ê
simultaneously. This
action will return the value displayed to the
factory default setting. Proceed with
calibration after performing this reset.
Factory default values are:
Simulated Flow: 150 GPM (568 LPM)
% FOAM:
0.5% Class A (Tank A)
1.0% Class B (Tank B) (If so
equipped)
