Pressure Governor Quick Start Guide

Use the appropriate Innovative Controls 4000675 series wiring harnesses for your 

application. Install the Fire Pressure Governor wiring harnesses on the rear of the unit 

and connect the vehicle power, interlocks, pump pressure sensors, and engine CAN 

network or analog control signals to the field wiring side of the cable harnesses.

The illustration below shows the six different standard FPG cable harnesses:

MOUNTING

WIRING

During power up the FPG displays the installed software version, and the current 

date and time. After initialization the FPG goes into READY mode by default. 

Verify that the Throttle Ready and OK to Pump interlocks operate correctly using the 

LED indicators and Status display on the front panel of the FPG.

The Status display will show OK to PUMP when both the Throttle Ready and Pump 

Engaged interlock inputs are active. If the engine is communicating correctly with the 

FPG the engine speed will be shown in the RPM display, otherwise the Status display 

will show NO J1939 ENGINE COMM. 

The Engine Temperature, Oil Pressure, and Transmission Temperature, and Battery 

icons will all be green if their conditions are normal. A yellow or red icon is an 

indicates a problem and additional information will be shown on the Status display. 

Press the PRESSURE button to place the FPG in pump pressure control mode. 

Press the RPM button to place the FPG in engine speed control mode. Use the 

rotary knob, or the + and – buttons to adjust the pump pressure or engine speed 

setpoints. 

The PRESET button is used to set the pump pressure or engine speed to a pre-pro-

grammed setting. The IDLE button causes the FPG to slow the engine to curb idle 

speed and return to READY mode.

PRESSURE SENSORS

Use Innovative Controls pressure sensor

part numbers 3050471 or 3050472 for

300 or 600 PSI full scale discharge

pressure measurement. Use the 3050473

or 3050474 pressure sensor for 300 or 600

PSI intake pressure measurement. Install the

pump discharge pressure sensor on the

discharge manifold side of the pump.

Install the pump intake pressure sensors on

the intake manifold side of the pump when

applicable.
