: Operation
The Simulated Flow mode of the Hale
FoamLogix system allows the operator to
operate the foam pump without
discharging water through a foam capable
discharge or when the flowsensor is not
functioning. The simulated flow mode is
used for draining the foam tank for
cleaning, checking calibration of the
feedback sensor, verifying foam pump
operation or manually controlling foam
injection if the flowsensor malfunctions. The
factory default simulated flow rate is 150
GPM (568 LPM). The simulated flow rate
and the concentrate injection percentage
rate can be set by using the display
readout and the rate adjustment buttons
on the control unit while in simulated flow
mode. The simulated flow function provides
manual operation of the foam injection
system required by NFPA standards.
CAUTION: When operating the Hale
FoamLogix in Simulated Flow mode an
outlet for the foam concentrate must be
provided to prevent excessive pressure
buildup in discharge piping or hoses.
Use the following procedure to operate the
Hale FoamLogix system using simulated
flow:
SIMULATED FLOW OPERATION
1. Locate the bypass hose and uncoil
to place the end into a suitable
container to collect the foam
concentrate.
2. Place the Hale FoamLogix system
BYPASS valve in the BYPASS position.
3. Energize apparatus electrical system
and turn Hale FoamLogix power switch
to ON.
4. When the Hale FoamLogix is in the
standby mode, FLOW LED lit, depress
and release the
é and ê buttons at the
same time. The display will show "S 150"
(or other preset default value) and the
FLOW LED will be lit. (see figure 4-9)
5. Depress the ON button. The leftmost
LED will light and the foam pump will
begin running. Foam concentrate will
flow out of the end of the bypass hose.
6. To end simulated flow operation, first
depress the ON button to stop the foam
pump.
7. Press DISPLAY button until the FLOW
LED is lit.
8. Depress and release the
é and ê
buttons at the same time. The display
will show the current water flow value
and the FLOW LED will be lit.
9. Deenergize apparatus electrical
system.
