6.3.1.5 Twister Operations (In SAM Auto Mode)
The SAM system limits the action of the Twister electronic throttle knob (see Figure 40, page 34)
while SAM is operating in Auto Mode. When SAM is in Auto Mode, the governor operation is in PSI
Mode by default for water and/or foam and RPM Mode by default for CAFS.
The Twister is not used when in SAM Auto Mode. The Twisters response (with SAM in Auto Mode)
is only intended to indicate the Twister is connected and working. The system returns to the auto-
mated set point almost immediately.
6.3.1.5.1
Emergency IDLE Button
Pressing the red IDLE button (Figure 84) ALWAYS provides EMERGENCY IDLE, causing SAM to
exit Auto Mode and enter Manual Mode. At the same time, causing the engine to go to idle and
the PSI/RPM Mode of the Pump Controller to no longer function. The Pump Controller displays
the governor MODE OFF screen (see Figure 85).
