This warning ribbon also contains an icon to inform the
operator of the severity of the warning.
Informational
Caution
Operation Halted
The warning ribbon will contain text informing the operator of
what has happened, what will happen, or what the operator
needs to do.
A warning message may be dismissed by pressing the
screen anywhere on the warning ribbon. If the warning is
still active the warning message will appear again after the
inhibit time has expired (default is 60 seconds
– configurable
in the OEM menu).
Low Foam Tank Level
The Hale SmartFOAM foam pump is interlocked with the
foam concentrate tank level switch. When the low level
switch is activated (foam tank is empty) the low tank caution
message will be shown and the foam pump will continue to
run for 60 seconds. At the 60 second limit the system and
pump will be forced OFF and the foam is empty operation
halted message will be displayed.
If the ON button is pressed before refilling the foam tank, the
system runs for 30 seconds before shutting down again and
showing the foam is empty operation halted message.
Foam Priming Error
In the event there is no foam feedback signal being received
when the foam pump starts (indicating a lack of foam
concentrate flow) the foam pump motor ramps up to full
speed attempting to establish foam concentrate flow. The
attempting to prime caution message will appear informing
the operator how many seconds the system will continue to
run before shutting down due to loss of foam prime.
If the system operates for a period of 35 seconds
(configurable in the Factory menu) without a feedback signal
the system turns itself OFF and shows the loss of prime
operation halted message.
PRIMING THE FOAM PUMP
In some instances, the foam tank may run dry while
operating the Hale SmartFOAM 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.
1. Turn the bypass valve to the BYPASS position.
2. With the fire pump flowing water from foam
discharge and the Hale SmartFOAM ON, observe
the hose from the bypass valve.
3. When foam concentrate flows from the hose turn the
bypass valve back to the INJECT position.
4. The pump is now primed and ready for normal
operation.
