SAM BOOST™ WITH SMART NOZZLE N
6.3.2.1
LOW NOZZLE PRESSURE Warning
The SAM™ SMART NOZZLE in operation continuously compares nozzle pressure against valve pressure
this difference is represented by Hose Loss in the Nozzle Information page. If the hose loss difference is
greater than the max limit while the hose is charged, the display will show a warning message asking to
continue increasing pressure to the rated pressure at the nozzle. This feature's purpose is to bring possible
issues to the attention of the operator. Issues with the charged hose may include kinking, pressure loss, etc.
This keeps the automatic pressure increase below NFPA pressure control limits.
6.3.2.2
SWITCHING GOVERNOR MODES Warning
Accepting this warning puts the governor into RPM mode. The SAM™ SMART NOZZLE automatically
controls the nozzle pressure in PSI mode only.
6.3.2.3
DECREASE GOVERNOR PRESSURE Warning
6.3.2.4
SWITCHING MODES Warning
Accepting this warning puts the valve into standard SAM mode and removes SAM™ SMART NOZZLE control.
The operator must manually control line pressure for the rest of the pump cycle.
6.3.2.5
ENABLE AUTO PRESSURE CONTROL Warning
Accepting this warning puts the system back into PSI mode. SAM BOOST™ pressure regulation will return.

INSTALLATION, OPERATING, & MAINTENANCE MANUAL
Do not continue increasing pressure until confirming there are no issues with the
hose. Ignoring to do so will result in damage to the hose and surrounding structure
of the truck and may cause bodily injury due to rapid hose expansion and movement.
Automatic pressure regulation will be removed if accepting this warning.
Uncontrolled pressure rises or loss may cause injury or bodily harm to user.
Automatic nozzle pressure regulation will be removed if accepting this warning.
Uncontrolled pressure rises or loss may cause injury or bodily harm to user.
Lowering the pump pressure under the desired line pressure will cause pressure loss
on the discharge line.
Automatic pressure regulation will be removed if accepting this warning.
Uncontrolled pressure rises or loss may cause injury or bodily harm to user.
Automatic pressure regulation will return after accepting this warning. This may
increase the engine rpm and system pressure which may increase pressure on all
discharge lines.
