Class1 FoamLogix 2.1A & 1.7AHP REV D - Manual (Page 71)

FoamLogix, Model 2.1A and 1.7AHP Class “A”
Electronic Foam Proportioning Systems 71
USER DIAGNOSTICS
Power indicator lamps are provided on the
distribution box and on the feedback sensor. The
LED on the feedback sensor flashes when the
sensor is receiving pulses from the flow sensor rotor
targets. These LEDs help to ease tracing of power
supply faults and eliminates some of the guesswork
in troubleshooting. If the system malfunctions make
sure the follow ing conditions are checked:
❑
All hose connections correct and tight (Refer to
appropriate system plumbing diagram in Section
3 “Installation.”)
❑
All electrical connections correct and tight (Refer
to appropriate system electrical diagram in
Section 3 “Installation.”)
❑
Apparatus electrical system energized with
power supplied to pump panel and Hale
FoamLogix.
Once the above conditions are met, proceed to the
system troubleshooting section to determine the
cause of the malfunction.
Hale FoamLogix systems consist of individual
subsystems working together to provide finished
foam solution at the proper percentage. Also see
heading “System Overview” on page 72.
The system is designed using modular compo-
nents making troubleshooting and repair easier.
Each subsystem has its own set of troubleshoot-
ing procedures. The procedures that follow provide
a logical flow path to isolate and correct a system
failure.
