Note: This is not necessarily an indication of
apparatus battery level or condition. It is only
an indication of adverse operating conditions.
For instance a bad battery cable can cause
the system to see low power even though the
batteries are fully charged.
In either case the system continues to run. If
conditions deteriorate to the point of potential
system damage, due to heat or low power, the
system returns to the STANDBY mode and
the error message remains until ON is pushed
again.
PRIMING THE FOAM PUMP
(When the Foam Tank Runs Dry)
In some instances, the foam tank may run dry
while operating the Hale FoamLogix system. The
foam pump is designed to pump liquid. When the
fire pump is running the foam pump may not pump
efficiently against 100 to 150 PSI (7 to 10 BAR)
back pressure. To re-establish foam concentrate
flow quickly the following procedure is used.
Turn the bypass valve to the 1. BYPASS position.
With the fire pump flowing water from foam 2.

observe the hose from the bypass valve.
When foam concentrate flows from the hose 3.
turn the bypass valve back to the INJECT
position.
The pump is now primed and ready for
normal operation.
