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.
The TPG+ 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.
