TOTAL PRESSURE GOVERNOR PLUS (TPG+)
3. Overview of the Total Pressure Governor Plus
The Total Pressure Governor Plus (TPG+) p/n 118710 is an SAE J1939 Controller Area Network
(CAN) device that controls engine speed using data communications directly 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 TPG+ 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 ch anges 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 TPG+. (Proper interlocking is required for normal operation – refer to Required Interlocking
section 4.3)

4.2.2. Pressure mode
Pressure mode (PSI) 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 TPG+. (Proper interlocking is required for normal operation – refer to Required Interlocking section
4.3)
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 opene d 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 increas e 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 engine control 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 gray Deutsch connector) and PUMP ENGAGED (pin 10 of the
gray Deutsch connector). These interlock inputs are activated when system power is applied (positive polarity).
The OEM is responsible for creating safe and effective interlocking routines.
The TPG+ utilizes back lit text below the switch panel to indicate interlock status.

4.4. PRESET switch operation
The PRESET switch brings the discharge pressure (or engine RPM, in throttle mode) to the configured
preset point (see section 5.2.2 and 5.2.4).
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 (hig her 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 regaining control operations can be aided by returning to this fixed pressure point with a
single switch press.
4.5. IDLE switch operation
Press and hold the IDLE switch 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 5.2.17).
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.

The indicators and displays on the TPG+ can be user configured for brightness in both a DAY mode and a NIGHT
mode (see sections 5.2.5 and 5.2.6). The TPG+ utilizes a light sensor on its front panel to determine if it is operating
in DAY or NIGHT mode. The sensitivity of the light sensor is not configurable.
• When the light sensor detects light the TPG+ is set to DAY mode.
• When the light sensor detects a low light condition the TPG+ is set to NIGHT mode.
The transition from DAY to NIGHT (or vice-versa) takes thirty (30) seconds.
Note: The TPG+ will remain in NIGHT mode if the light sensor is blocked by stickers, tape, etc.

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 mo dification,
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 engi nes, Mercedes Benz (MBE)
engines, Volvo, and others. The Scania engine allows control by proprietary J1939 messa ges 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. The setup menu may be accessed
anytime the TPG+ is in idle mode (see section 3.3.1).
There are 4 set up menus available: menu level 1 (basic setup menu), menu level 2, menu level 3 and menu level 4
(factory menu). All configurations and calibrations are saved in non-volatile memory and will not be lost with power
disruptions.
