SIMULATED FLOW OPERATION
The Simulated Flow mode of the Hale FoamLogix
system allows operation of the foam pump without
discharging water through a foam ca pable discharge
or when the flow sensor 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
❑
Manually controlling foam injection if the flow
sensor malfunctions.
The factory default simulated flow rate is 150
GPM (568 LPM). The simulated flow rate and the
concentrate injection percentage rate are set by the
rate adjustment buttons on the control unit display,
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.
Simulated flow sequence
Uncoil and place the end of the bypass hose 1.
into a suitable container to collect the foam
concentrate.
Place the BYPASS valve in the 2. BYPASS
position.
Energize the apparatus electrical system and 3.
press Hale FoamLogix power button ( i ) to turn
ON the system.
The Hale FoamLogix enters the STANDBY 4.
mode. (See Figure 41: “Display - Simu lated
