6.3.4.2.2 Using RPM Mode
RPM Mode governor control of the apparatus is very similar to Auto Mode control of the appa-
ratus, in that, the engine speed is being controlled to maintain a desired/selected set point. RPM
Mode would be used anytime traditional governor operations are desired/required (typically dur-
ing annual NFPA required pump testing) or if SAM Auto Mode fails or does NOT provide the de-
sired control of the pump.
To select the desired/required engine speed, simply use a preset (see the paragraph above if the
applicable preset exists). Otherwise, use the increase and/or decrease arrowhead on the RPM
set point icon group to select the desired/required engine speed (which is indicated in the EN-
GINE SPEED–––– RPM area of the Pump Controller home screen). To use RPM Mode, perform
the following.
A.
Exit SAM Auto Mode as follows.
Touch MANUAL MODE button ( , see Mode Control on Figure 20, page 23).
If Pump Controller displays MODE PSI (see Figure 32, page 30), touch MODE
PSI arrowhead (directly above ENGINE SPEED icon group).
B. On Pump Controller RPM Mode screen, touch + or—arrowhead to digitally display
desired/required engine speed.
6.3.5 Twister Operations (In SAM Manual Mode)
The Twister electronic throttle knob is active while SAM is operating in Manual Mode. Turning the
knob raises or lowers the engine RPM to achieve the resulting Master PSI setpoint (if the gover-
nor is operating in PSI Mode) or directly sets the engine RPM if the governor is operating in RPM
Mode. Note that the Master discharge pressure is being controlled, NOT individual discharge(s),
therefore, any change affects the pressure of all active discharges.
Pressing the red IDLE button ALWAYS provides EMERGENCY IDLE causing the engine to go to idle
and the governor to go into OFF mode.
For more detailed Twister electronic throttle information reference Class 1 Technical Product
Datasheet, Sentry Pressure Governor (P/N 3045-101-00-CL1 3045-102-00-CL1).
6.3.5.1
PSI Mode Operations.
The THROTTLE READY indicator (Green LED, left-hand side of housing) and the ACTIVE (Blue LED
right-hand-side of housing) must be illuminated for the Twister control knob to control the engine
RPMs. With SAM in Manual Mode, perform the following to change the governor PSI set point.
NOTE
The direction the Twister control knob must be turned to increase/decrease the Pres-
sure/RPM set point is configurable to CW equals increase and CCW equals decrease
OR CW equals decrease and CCW equals increase. [Reference Class 1 Technical Prod-
uct Datasheet, Sentry Pressure Governor (P/N 3045-101-00-CL1 3045-102-00-CL1)
for configuration instructions.]
A. At Twister, turn control knob (according to configured direction, see note above)
to increase/decrease Master discharge pressure set point. (Typically, CW = in-
crease.)
