Section 4 Operation
DESCRIPTION
Operation of Hale FoamLogix systems is con trolled
by the Digital Display Control Unit, pro vided with
four push buttons (pads). (See Figure
36: “Digital Diaplay Control Unit Overview.”)
The Hale FoamLogix system constantly monitors
water and foam concentrate flow values, main taining
foam injection at the specified concentrate injection
rate. The system responds to variations in water flow
by increasing or decreasing the speed of the foam
pump.
On initial power up of the apparatus, the Hale
FoamLogix system begins a brief self-diagnostic
routine. When completed, the system enters the
STANDBY mode. The
FLOW LED lights and the
dsiplay shows the current water flow rate in the
monitored discharge pipe.
Pressing the DISPLAY button (i) cycles through
the four functions as indicated by the red LED
illuminating under each function.
Note: TOTAL FLOW and TOTAL FOAM values
may be reset any time they are displayed. When
the
% FOAM LED is lit, or in any other function
mode, the foam concentrate injection rate may
be set to the desired value, if different from the
default value. This may be adjusted prior to or
during foam operations by pressing the and
buttons. Also see heading “Control unit functions”
on page 60.
When the red
ON button is pressed, the FLOW
LED illuminates indicating that the system is
ready. If water flow is present the foam pump
starts and injects foam concentrate into the
discharge stream.
The bar graph lights when foam is being injected
and indicates system capacity.
When the
ON button is pressed again the LEDs
extinguish, indicating that the system is in STANDBY
mode and the foam pump STOPS. However, other
system monitoring functions continue.
