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.

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…

4.2.2. Pressure mode
Pressure mode maintains a set pump pressure by monitoring the discharge pressure transducer and modifying the
pump speed by adjusting the engine RPM. The operator can modify the set pump pressure with the control
switches on the SENTRY.
Pressure mode affords the most safety to the operator by not allowing potentially hazardous pressure spikes. The
SENTRY will maintain the set pump pressure even when discharge lines are actively opened and closed as long as
the water supply is sufficient. T he SENTRY will automatically increase engine speed when pump pressure has
decreased due to discharge lines being opened. The increase in engine speed will return the pump pressure to the
desired set pressure (and vice-versa when discharge lines are closed).

4.3. Required interlocking
The SENTRY requires interlocks before engine control operations are permitted. The SENTRY provides two
interlock inputs that allow easy separation of pumping operations and throttle/high idle operations through two inputs
dedicated as system interlocks: THROTTLE READY (pin 2 of connector C) and PUMP ENGAGED (pin 4 of connector
D). These interlock inputs are activated when system power is applied (positive polarity).
The OEM is responsible for creating safe and effective interlocking routines.
The SENTRY uses green icons to indicate the status of the interlock s.

4.4. PRESET button operation
The PRESET buttons bring the discharge pressure (or engine RPM, in throttle mode) to the configured
preset point (see section 6.4.2 to 6.4.5).
Using a PRESET button is a method of smoothly and expeditiously attaining water pressure and flow, but it is not
intended to be the initial attack pressure. Attack pressures and flows should be determined by the actual fire status
and manually achieved for best operation.
PRESET is an operational convenience and needs to be considered as a fixed point (higher or lower than the current
point) that can be achieved with a single button press.
Note: Initiating pumping operations is simplified by bringing the pump to a preset pressure with a single button press.
Consequently, securing or regaining control operations can be aided by returning to this fixed pressure point with a
single button press.
4.5. IDLE button operation
Note: In view of the fact that driveline stress can be induced by quick changes in engine speed, depending on rpm
and torque load, the engine speed is ramped to idle over a short duration to minimize the effect of driveline kick.
Press and hold the IDLE button (on Sentry or Twister) for one second to release engine
RPM control back to the engine ECU. The engine RPM will promptly go to its configured
curb idle (see section 6.6.5).

5.3.1. Intake or Discharge Sensor Fault
The Intake and Dischgarge Sensor Fault warning messages indic ate that t he as sociated pressure sensor signal
voltage is out of range (<0.30 VDC or >4.90 VDC). When this occurs the SENTRY does not have valid pressure
data and responds by switching operation to THROTTLE mode (where pressure data is not required). There are
typically four reasons the pressure sensor voltage is out of range:
• The pressure sensor is damag ed.
• The pressure sensor signal wire is broken.
• The pressure sensor ground wire is broken (signal voltage will be at 5.00 VDC).
• The pressure sensor supply voltage wire is broken (signal voltage will be at 0.00 VDC).
5.3.2. Water Supply Insufficient, Discharge Pressure Less Than 30 Psi, and Critical: Sentry In Stand By. Check Water Source
Water Supply Insufficient, Discharge Pressure Less Than 30 Psi, and Critical: Sentry In Stand By. Check
Water Source work together and in sequence when the discharge water pressure cannot be maintained due to
cavitation or inadequate water supply.
• The Water Supply Insufficient message appears firs t after the SENTRY has attempted to maintain
discharge pressure by increasing the engine RPM. Failing to maintain the discharge pressure, the
SENTRY drops the engine speed to 1100 RPM and begins increasing the RPM as part of the Supply
Intake Protection (SIP) routine.
• The Discharge Pressure Less Than 30 Psi message appears after the Supply Intake Protection (SIP)
routine has failed and the discharge pressure has dropped below 30 PSI. The SENTRY maintains the
engine speed at 1100 RPM for the time period defined by the pressure time-out variable (3 seconds
default, see section 6.6.8).
• The Critical: Sentry In Stand By. Check Water Source message appears after the SENTRY has
switched to STANDBY mode (IDLE). This message informs the operator that the SENTRY could not
maintain a discharge pressure of 30 PSI or more. The water supply must be verified.
5.3.3. Unable To Maintain Discharge Pressure
The SENTRY in PRESSURE mode maintains the operator set discharge pressure by adjusting the engine RPM.
The SENTRY increases the engine RPM to return to the operator’s set discharge pressure when a pressure drop is
detected. The SENTRY maintains the Limit RPM and displays the warning message when the SENTRY cannot
fully regain the operator’s set discharge pr es sure.

For example: The SENTRY is maintaining the operator’s set discharge pressure of 100 PSI at 1100 RPM. The
pressure drops to 90 PSI and the SENTRY compensates by increasing the engine RPM. The SENTRY continues
increasing engine speed until 1400 RPM is reached but the discharge pressure has only increased to 92 PSI so the
SENTRY maintains 1400 RPM and displays the warning message.
5.3.4. Discharge Pressure Has Increased More Than 50 Psi Since Setting Rpms
The SENTRY in THROTTLE mode maintains the operator set engine RPM. But the SENTRY will limit the
discharge pressure if the pressure recorded when the RPM was last set has increased more than 50 PSI. The
SENTRY will reduce the engine RPM to maintain the pressure increase to no more than a 50 PSI differential and
display the warning message. The SENTRY does not attempt to regulate pressure while in THROTTLE mode, but
it will attempt to limit a pressure increase to a maximum of 50 PSI over the pressure detected when the operator set
the desired engine RPM.

For example: The SENTRY is maintaining the operator’s desired engine speed of 1100 RPM (at a discharge
pressure of 100 PSI). The discharge pressure increases to 160 PSI (e.g. a discharge line was closed) and the
SENTRY decreases the engine RPM until the discharge pressure is reduced to 150 PSI (50 PSI differential).
5.3.5. Communication with engine is lost
The SENTRY receives engine RPM data via CAN communication (PGN 61444, SPN 190). The SENTRY displays
this warning message after not receiving the RPM data for 4 or more seconds.
Note: If the SENTRY is configured for a CAN control and this warning message is active due to a CAN bus
problem, then the control of the engine RPM cannot be certain since the engine ECU may not receive engine
speed request data from the SENTRY.

6. Sentry Setup Menus
6.1. Engine compatibility
The factory default settings of the SENTRY make it “out of the box” ready to operate a Cummins engine programmed
with the Emergency Vehicle Calibration. Typically, for the default configuration no values will require modification,
other than changing the desired engine rpm, high-idle rpm and pump pressure preset values.
The governor is capable of controlling any engine that allows J1939 PGN0 (Torque Speed Control) messages from a
unique source address. These engines include various Detroit Diesel DDEC engines, Mercedes Benz (MBE)
engines, Volvo, and others. Programming of the source address or other parameters on the engine ECM may be
required. The Scania engine allows control by proprietary J1939 messages and is supported by the SENTRY. In
cases where an engine does not support data link control, the SENTRY can be configured to control the engine with
an analog signal coupled to the engine remote PTO throttle input. Contact Class 1 or visit our website
(www.class1.com) for a complete engine compatibility list.
