USER CALIBRATION
The complete Hale FoamLogix Systems; foam pump
and motor assembly, control unit and flow sensor, is
tested at the factory before shipping to the installer.
If the Hale FoamLogix system is properly installed,
further calibration IS NOT necessary until delivery to
customer.
The system permits easy checking of component
calibration to assure accurate operation. The
calibration process verifies component calibration
and allows adjustments to the flow sensor and
feedback sensor display readings, to allow for
variations in apparatus piping configurations and
end user selected foam concentrate.
Default values for simulated flow and foam
concentrate injection rate may be set to end user
specifications while in the calibration mode.
Note: The Hale FoamLogix system is calibrated
at the factory to U.S. measurement (GPM, PSI,
GALLONS, etc.) units. The system may be set
to Metric units. (See heading “English to Metric
Units” on page 58.) However, the same unit
of measurement must be used throughout the
calibration process to ensure proper proportioning
by the system.
Recalibration of the system may be required ONLY
after major repairs or component changes are made
to the Hale FoamLogix foam system. Different
viscosity foam concentrates may also required
recalibration.
ENTERING PASSWORDS
Entering passwords is accomplished using the
control unit function buttons.
To enter passwords, press and hold the DIS PLAY
button. The display shows PASS, then clears. While
continuing to hold the display button press the  or
 buttons sequentially to enter the password. See
Table 25: “Password Sequence.”

RESTORE FACTORY DEFAULTS
To return to the factory default values, enter the
restore factory values password (    ) as
previously described.
Once the password is entered correctly the unit
displays FAC and returns to normal operation.
Factory default values:
Simulated Flow.... 150 GPM (568 LPM) %
FOAM .............. 0.5% Class “A”
Also see Figure 26: “Display - Password and
Calibration Modes” on page 54.
CALIBRATION
To enter calibration password press and hold 1
the SELECT DISPLAY button ( i). The display
shows PASS, then clears.
While holding 2 i pressed, enter the calibra tion
password ().
The display shows 3 CALL for several seconds,
followed by L (or O when display is set to
metric). (See Figure 26: “Display - Password
and Calibra tion Modes” on page 54.)
The FLOW LED (Water Flow sensor
Calibration) also illuminates. (See Figure
27: “Display - Flow Sensor Calibration” on
page 54.)
