PBA100 Rev0407 INTRODUCTION Overview The Fire Research PumpBoss pressure governor uses state of the art programmable microprocessor technology and operates in one of two modes, pressure or RPM. It will maintain a steady pump discharge pressure within system capabilities by controlling the engine speed.
PBA100 Rev0407 Specifications The PumpBoss is available in various models. Each model is programmed to interface with specific engines. All models provide the same functions, controls, and digital readouts for the management of pump discharge pressure. Display Module Supply Power: 12/24 VDC Supply Current: 0.5 Amps...
PBA100 Rev0407 GENERAL DESCRIPTION The PumpBoss pressure governors are compatible with the following engines: PBA101 Cummins IS Series PBA102 Detroit Diesel PBA104 Navistar PBA105 Caterpillar PBA106* Ford PBA108 Scania PBA109* PBA110 Mercedes * Note: An adapter and cable assembly replaces the basic 8-pin cable when connecting the PumpBoss to a Ford or GMAC engine.

PBA100 Rev0407 Pressure Sensor The pressure sensor is mounted on the pump discharge manifold. It provides an input signal to the control module that is proportional to the discharge pressure. Engine Coolant Temperature Sensor The engine coolant temperature sensor is installed as necessary. Engine Oil Pressure Sensor The oil pressure sensor is installed as necessary.
PBA100 Rev0407 Controls and Indicators All controls and indicators are located on the front of the control module. (Refer to Figure 1.) See Operation and Programming Sections for more information. OIL PRESSURE LED Display Shows engine oil pressure. The LEDs will be green when the pressure is within normal limits and red when it is not.
PBA100 Rev0407 Control Knob When rotated changes the pressure or RPM setting. The setting will increase or decrease proportionally to the speed and direction the control knob is rotated. RPM LED The LED is on to indicate operation in the RPM mode. PSI LED The LED is on to indicate operation in the PSI mode.
PBA100 Rev0407 INSTALLATION Install Control Module 1. Measure and mark mounting location for control module panel cutout and mounting screw holes. Make sure there is clearance behind the panel for the module and cables before cutting holes. Refer to Figure 2 for layout and dimensions.
PBA100 Rev0407 Install Pressure Sensor The discharge pressure sensor is mounted on the discharge manifold of the pump. If there is a check valve in the discharge side of the pump, mount the discharge sensor before the check valve. T-fittings can be used to mount the pressure sensors. Note: Install the pressure sensor upright so that the water in the end of the sensor is able to drain back into the pipe.
Pin 6 on the 12-pin connector at the rear of the control module is provided to connect an optional buzzer. Connect the ground side of the buzzer to pin 6. Maximum current through pin 6 is 300 mA. The buzzer ordered from FRC requires a 1-1/8 inch diameter mounting hole. (Refer to the Wiring section.)
PBA100 Rev0407 OPERATION On power-up the PumpBoss will be in the pressure mode of operating. The RPM display will show engine at idle RPM, the three LED bar graphs will be green indicating readings within normal ranges, and the message display will alternate between showing the date and time.

PBA100 Rev0407 Pressure Mode Operation In the pressure mode of operation the PSI LED will be on. The PumpBoss will maintain a constant discharge pressure within system capabilities. It will adjust the engine RPM automatically to compensate for variations in pressure. Note: When changing from RPM mode to pressure mode the pressure setting will be the pressure that the pump was operating at in RPM mode.

PBA100 Rev0407 Running Away From Water, No or Low Supply Water There are situations during pump operations when there may be no or low supply water. This can be due to an empty water tank, a problem on the intake line, or when switching the water supply source.
PBA100 Rev0407 RPM Mode Operation In the RPM mode of operation the RPM LED will be on. The PumpBoss will maintain a constant engine RPM. The pump discharge pressure can vary but, as a safety feature, the PumpBoss limits the increase in pressure to 30 PSI over the last established PSI value. As the discharge pressure approaches this limit the PumpBoss will automatically lower the RPM to prevent a high pressure surge.
PBA100 Rev0407 Switching Between Operating Modes • No variation in discharge pressure or RPM will occur when changing between pressure and RPM modes. • When changing to RPM mode, the RPM setting will be the RPM that the pump was operating at in pressure mode. •...
PBA100 Rev0407 Preset Settings (Pressure or RPM) The preset button allows the operator to go to a pre-programmed pressure or RPM setting during operations. The setting will be shown in the message display. This procedure is to change the setting in the program. Note: The engine must be running and the pump engaged interlock circuit must be closed (the THROTTLE READY LED must be on).
PBA100 Rev0407 Display Stored Data Both the RPM and the message displays are used to show stored data. Accumulated Hours and Transmission Temperature Accumulated hours are stored in memory for engine operation, pump operation, last incident, and current incident. The menu button allows the operator to gain access to this stored data.
PBA100 Rev0407 PROGRAMMING To gain access to the program features a four digit program code must be entered. Review the Program Code Descriptions for the proper four digit code. Both the MENU and SILENCE buttons are used to enter a program code. The RPM display is used to show the codes.
PBA100 Rev0407 Program Code Descriptions When a valid four digit program code has been entered, stored data or program options will show in the displays. The MENU and SILENCE buttons are used to change the data. The SILENCE button will select the digit that is to be changed. The MENU button will change the digit or change the option choice.
PBA100 Rev0407 WIRING The following figures include the schematics, wiring diagrams, block diagrams, and cables for the PumpBoss series governors. Connectors and Cables For most engines the PumpBoss receives engine RPM, oil pressure, and coolant temperature data over the J1939 data link from the ECM. Some engines do not broadcast this data over the data link and sensors may need to be installed.
