3. Overvi ew of the Sentry Governor
The Sentry Governor (p/n 3045-101-00-CL1 vertical, p/n 3045-102-00-CL1 horizontal) is an SAE
J1939 Controller Area Network (CAN) device that controls engine speed using data
communications direc t l y to the engine ECU or through with an analog control signal. By operating
on the J1939 network, the governor is able to monitor engine RPM and other pertinent data directly
from the engine ECU. Engine information is available directly so that NFPA required
instrumentation is delivered through a single unit saving panel space and delivering engine specific
warnings as determined by each engine manufacturer.
Control algorithms are optimized to take advantage of the J1939 CAN data to yield crisp and
accurate control of engine and subsequently pump speed and pressure output.
For engines that may not support the data link control, an analog output signal is available to
provide precise control of the engine speed and pressure.

The SENTRY saves pump panel space by incorporating easy to read numeric displays for Pump Intake
pressure, Pump Discharge pressure, and engine RPM in accordance with NFPA standards.

Figure 3. Twister controls and indicato rs.
3.1. Mode and Interlock indicators (Sentry)
Green icons indicate the status of the three (3) interlocks: throttle ready, pump engaged, and okay to pump.
The mode indicators consist of two (2) icons to show the governor’s current operating mode. The PRESSURE MODE
ICON (yellow) indicates the governor is operating in pressure mode and the RPM MODE ICON (blue) indicates the
governor is operating in throttle mode. When both icons are OFF the governor is in idle mode (standby).
3.2. Pump discharge pressure display (Sentry)
The pump discharge pressure display shows the pressure as determined by the discharge pressure sensor. By
default, this display only shows positive pressure in pounds per square inch (PSI), but it may be set up to display in
metric units (see section 6.4.1).
3.3. Pump intake pressure display (Sentry)
The pump intake pressure display shows the pressure as determined by the intake pressure sensor. By default, this
display shows positive pressure in pounds per squ are inch (PSI) and negative pressure (vacuum) in inches of
mercury (inHg), but it may be set up to display in metric units (see section 6.4.1).
3.4. Mode, Preset, and Idle buttons (Sentry)
The four (4) control buttons are color coded and labeled for easy identification.
3.4.1. IDLE
The IDLE switch (red) forces the governor to idle mode (standby). Pressing and holding this button for one
second while in rpm mode or pressure mode will cause the engine to ramp down to its idle position.
3.4.2. PRESET 1
The PRESET 1 button (orange) sets the governor to the configured preset 1 engine RPM while in throttle mode, or
preset pressure while in pressure mode.

3.4.3. PRESET 2
The PRESET 2 button (orange) sets the governor to the configured preset 2 engine RPM while in throttle mode, or
preset pressure while in pressure mode.
3.4.4. MODE
The MODE button (green) sets the governor to either throttle mode (RPM) or pressure mode (PSI). The correct
interlocks must be present for the system to begin governor operation: throttle ready for RPM mode, throttle ready,
pump engaged, and okay to pump for PSI mode.
3.5. “Soft” buttons (Sentry)
The four (4) soft buttons have functions based on the current operating mode and/or warning messages display.
These buttons are typically used for menu navigation, configuration, and warning message evaluations.
3.6. Information displays (Sentry)
The Sentry has six (6) information displays.
3.6.1. Engine RPM display
The engine RPM display shows the current engine RPM as reported by the Electronic Engine Controller 1 (EEC1)
SAE J1939 network data message transmitted by the vehicle ECU.
3.6.2. Battery voltage display
The battery voltage display shows the current system voltage as determined by the voltage present on pin 1 of
connector B.
3.6.3. Coolant temperature display
The coolant temperature display shows the current coolant system temperature as reported by the Electronic
Engine Temperature 1 (ET1) SAE J1939 network data message transmitted by the vehicle ECU. The temperature
will be displayed in degrees Fahrenheit (°F) or degrees Celsius (°C) dependent on the unit of measure configured
in the setup menu (see section 6.4.1
3.6.4. Oil pressure display
The oil pressure display shows the current oil pressure as reported by the engine Fluid Level/Pressure 1 (EFL/P1)
SAE J1939 network data message transmitted by the vehicle ECU. The pressure will be displayed in PSI, kPa, or
Bar dependent on the unit of measure configured in the setup menu (see section 6.4.1
3.6.5. Transmission temperature display
The transmission temperature display shows the transmission oil temperature as reported by the Transmission
Fluids 1 (TRF1) SAE J1939 network data message transmitted by the vehicle TCU. The temperature will be
displayed in degrees Fahrenheit (°F) or degrees Celsius (°C) dependent on the unit of measure configured in the
setup menu (see section 6.4.1
3.6.6. Fuel economy display
The fuel economy display shows the current fuel usage per hour as reported by the Fuel Economy, Liquid (LFE1)
SAE J1939 network data message transmitted by the vehicle ECU. The fuel economy will be displayed in gallons
per hour (G/h) or liters per hour (L/h) dependent on the unit of measure configured in the setup menu (see section
6.4.1

3.7. Ready indicator (Twister)
The green READY indicator shows the status Sentry throttle ready interlock.
3.8. Active indicator (Twister)
The blue READY indicator indicates that the Twister is ready to control the Sentry. This is mainly used with dualgovernor applications to indicate which governor is active for user operation.
3.9. Control knob (Twister)
The control knob is the operator’s interface for controlling the Sentry’s engine speed (throttle mode) and target
pressure (pressure mode). The control knob can be configured to increase engine speed/target pressure with
clockwise or counter-clockwise rotation (see section 6.7.1).
3.10. Idle button (Twister)
The Twister’s idle button performs the same task as the idle button on the Sentry. Press and hold this button for one
second while in rpm mode or pressure mode to force the engine to ramp down to its idle position.

4.2. Operating mode selection
The SENTRY has two operating modes: throttle mode (RPM) and pressure mode (PSI).
There is no variation in engine RPM or pump pressure when changing between throttle mode and pressure mode.
Pressure mode is the desired operating mode because it offers protection from pressure changes that could
injure personnel.
4.2.1. Throttle mode
Throttle mode (RPM) maintains a set engine RPM and will not deviate until the operator changes the RPM with
the control switches on the SENTRY. (Proper interlocking is required for normal operation – refer to Required Interlocking
section 4.3)
Throttle mode is typically used when…

Press the MODE button to select throttle mode. The RPM
mode indicator LED will illuminate blue.
Rotate the Twister knob in the INCREASE direction to
increase or the DECREASE direction to decrease the engine
RPM set point. The direction of increase can be set to
clockwise or counter-clockwise (see section 6.7.1).
Press a PRESET button to set the engine speed to the
configured preset RPM - as long as the pump pressure is
less than 10 PSI (see section 4.4).
Configure the throttle mode presets through the USER
Menu (see section 6.4.2 and 6.4.4)
Press the IDLE button (on Sentry or Twister) at any time to
set the SENTRY back to standby. Both mode indicator LEDs
will turn off when the engine speed reaches idle (see section
4.5).
