TOTAL PRESSURE GOVERNOR (TPG)
3. Total Pressure Governor Overview
The Total Pressure Governor (TPG) p/n 117155 is an SAE J1939 Controller Area Network (CAN)
device that controls engine speed using data communications directly to the engine ECU or 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. Engi ne inf ormation 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.

3.1. Display
The display shows the pertinent governor information: engine RPM, set pressure, warning and information messages.
3.2. Interlock status indicators
Backlit text indicates the status of the three (3) interlocks: pump engaged, okay to pump, and throttle ready. Throttle
ready and pump engaged are physical inputs into the TPG’s 12 pin connector (pins 2 and 10 respectively). Okay to
pump interlock status can be configured to beco me active when both the throttle ready and pump engaged interlocks
are present (default) or when the TPG’s pin 4 physical input is active (see section 5.2.34).
3.3. Control switches
The six (6) control switches are color coded and labeled for easy identification.
3.3.1. IDLE
The IDLE switch (red) forces the governor to idle mode (standby). Pressing and holding this button for one second
while in rpm or pressure mode will cause the engine to ramp down to its idle position.
3.3.2. MENU/SILENCE
The MENU/SILENCE switch (blue) is used to silence the alarm, cycle through the display items, and enter the
setup menu.
3.3.3. PRESET
The PRESET switch (orange) sets the governor to the configured preset engine RPM while in throttle mode, or
preset pressure while in pressure mode.
3.3.4. MODE
The MODE switch (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.
3.3.5. INC
The INC [increase] switch (yellow) is used to increase the engine RPM or pressure set point.
3.3.6. DEC
The DEC [decrease] switch (yellow) is used to decrease the engine RPM or pressure set point.
3.4. Mode indicator
The mode indicator consists of two (2) LEDs to show the governor’s current operating mode. The PSI LED (yellow)
indicates the governor is operating in pressure mode and the RPM LED (blue) indicates the governor is operating in
throttle mode. When both LEDs are OFF the governor is in idle mode (standby).

3.6. Coolant temperature monitor
The coolant temperature monitor is comprised of three (3) LEDs (green, yellow, and red). The active LED color

temperature status can also be set to react to user desired points (see section 5.2.22). The alarm will activate when
the coolant temperature monitor is in condition RED.

4.2. Operating mode selection
The TPG has two operati ng m odes : throttle mode (RPM) and pressure mode (PSI).
Press the MODE switch to select an operating mode. An operating mode will only be activated if the
required interlock(s) are in place (see section 4.3).
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 TPG’s control switches.
Throttle mode is typically used when…
• priming the pump
• connected to a stand pipe
(Proper interlocking is required for normal operation – refer to Required Interlocking section 4.3)
• the water supply pressure stability is questionable
• acting as a relay pumper
Press the MODE switch to select throttle mode. The display will
momentarily show “GOV=THROTTLE” and the RPM mode
indicator LED will illuminate blue.

4.2.2. Pressure mode
Pressure mode (PSI) maintains a set pump pressure by monitoring the pressure transducer and modifying the
pump speed by adjusting the engine RPM. The operator can modify the set pump pressure with the TPG’s control
switches.
Pressure mode (PSI) affords the most safety to the operator by not allowing potentially hazardous pressure
spikes. The TPG will maintain the set pump pressure even when discharge lines are actively opened and closed
as long as the water supply is sufficient. The TPG 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 TPG requires interlocks before engi ne contr ol operations are permitted. The TPG 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 the 12-pin Deutsch connector) and PUMP ENGAGED (pin 10 of the
12-pin Deutsch connector).
A third interlock input (pin 4 of the 12-pin Deutsch connector) may be configured to control OKAY TO PUMP (menu
level 5, see section 5.2).
These interlock inputs are activated when system power is applied (positive polarity).
The OEM is responsible for creating safe and effecti ve interlocking routines.
The TPG utilizes back lit text below the main display to indicate interlock status.

4.4. PRESET switch operation
Using the PRESET switch 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 switch press.
Note: Initiating pumping operations is simplified by bringing the pump to a preset pressure with a single switch press.
Consequently, securing or reg aini ng contr ol operations can be aided by returning to this fixed pressure point with a
single switch press.

4.5. IDLE switch 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.

TOTAL PRESSURE GOVERNOR (TPG)
5. Governor Control Setup Menu
5.1. Engine compatibility
The factory default settings of the TPG 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 TPG. In cases
where an engine does not support data link control, the TPG 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.
5.2. Enter the setup menu
The setup menu allows access to the configuration and calibration screens. There are 5 set up menus available:
menu level 1 (basic setup men u), menu level 2, menu level 3, menu level 4 (factory menu), and menu level 5
(restricted). All configurations and calibrations are saved in non-volatile memory and will not be lost with power

A TPG set to Analog control mode (see section 5.2.14) may use the Auto Scale configure method to automatically set
the IDLE voltage (5.2.33) and GAIN setting (Error! Reference source not found.).
The engine must be running and the interlocks (as defined in section 4.3) must be enabled when running the Auto

The TPG will actively control the engine RPM during Auto Scale. Make certain that all operational
precautions are observed and a trained operator is present.
