TGA100 Rev0106 INTRODUCTION Overview The Fire Research INControl pressure governor and all-in-one instrument panel uses state of the art programmable microprocessor technology. It will maintain a steady pump discharge pressure by controlling engine speed or hold a selected engine RPM. It offers complete engine control and remote display in a single compact unit.
TGA100 Rev0106 Specifications The INControl 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. Control Panel Supply Power: 12 VDC Supply Current: 1.0 Amp...
TGA100 Rev0106 GENERAL DESCRIPTION The INControl pressure governor and all-in-one instrument panel engine type can be programmed form the facyory or or or during installation. (Refer to Programming section.) It is compatible with the following engines: TGA101/TGA201 Cummins IS Series TGA102/TGA202 Detroit Diesel TGA104/TGA204 Navistar TGA105/TGA205 Caterpillar...

0 PSI, and calibrates the display to show 0. If there is pressure in the plumbing where the sensor is mounted this will cause the display to be calibrated to a false 0. To avoid this FRC recommends: Drain the pump and plumbing to ensure there is no residual pressure.
TGA100 Rev0106 Controls and Indicators All controls and indicators are located on the front of the control module. (Refer to Figure 1.) The LED digital display has daylight bright digits at least 0.56 inch high. PUMP DISCHARGE Display Shows the pump discharge pressure during normal operations. PSI LED The red PSI LED is on to indicate operation in the pressure mode.
TGA100 Rev0106 INC Button During operations the button raises pressure or RPM setting. DEC Button During operations the button lowers pressure or RPM setting. OK TO PUMP Light This LED will be on when the required interlock conditions are met and the governor is ready to begin pump operations.
TGA100 Rev0106 INSTALLATION When the governor is programmed at the factory there will be a label on the governor specifying the engine type. If there is no label on the governor the engine type must be verified/programmed per the Programming procedure. Install Control Panel 1.
TGA100 Rev0106 Install Pressure Sensors The two pressure sensors are mounted on the discharge and intake manifolds of the pump. If there is a check valve in the discharge side of the pump, mount the discharge transducer before the check valve. T-fittings can be used to mount the pressure transducers.
Install the buzzer close to the control panel so the audible warning is easily associated with the visual warning on the display. The optional buzzer provided by FRC requires a cutout hole of 1-1/8" (1.125"). Pin 7 on the 8-pin connector at the rear of the control module is provided to connect an optional buzzer.
TGA100 Rev0106 OPERATION On power up the INControl will be in the pressure mode of operation. The RPM display will show IdLE. If there is a problem, the RPM display will show an error code. Refer to the Diagnostics section for error code descriptions. The minimum pump discharge pressure must be greater than 15 PSI for the INControl governor to take control of engine speed.
TGA100 Rev0106 Pressure Mode Operation In the pressure mode of operation the PSI LED will be on. The INControl will maintain a constant discharge pressure. 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.
TGA100 Rev0106 RPM Mode Operation In the RPM mode of operation the RPM LED will be on. The INControl will maintain a constant engine RPM. The pump discharge pressure can vary but, as a safety feature, the INControl limits the increase in pressure to 30 PSI over the last established PSI value. As the discharge pressure approaches this limit the INControl will automatically lower the RPM to prevent a high pressure surge.
TGA100 Rev0106 Change Preset Setting (Pressure or RPM) The preset button allows the operator to go to a pre-programmed pump pressure or engine RPM during operations. The setting will be shown on the PSI/RPM setting 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 OK TO PUMP LED must be on).
TGA100 Rev0106 High Idle The INControl programming includes a high idle function that is controlled by the High Idle Switch. To activate the high idle set interlocks as called for by SOP (normally this would include the transmission in neutral and the parking brake on ). Set the High Idle switch to ON.
TGA100 Rev0106 PROGRAMMING This program information is provided for installers and should not be changed once the apparatus is put into service. The governor response speed may need to be adjusted if changes are made in the pump drive system after the governor is installed. Program Governor Response Speed Due to variations in pump drive systems the INControl program may be adjusted if necessary to improve performance.
TGA100 Rev0106 Preliminary Set-up This procedure can be performed prior to installing the INControl on the apparatus. Connect 12 volt power as follows: 12-Pin connector pin 1 (red wire) +12 VDC 12-Pin connector pin 2 (black wire) Ground If the INControl is installed on the apparatus, turn on electrical power. Do not operate the engine.
0 PSI, and calibrates the display to show 0. If there is pressure in the plumbing where the sensor is mounted this will cause the display to be calibrated to a false 0. To avoid this FRC recommends: Drain the pump and plumbing to ensure there is no residual pressure.
TGA100 Rev0106 WIRING The following figures include the schematics, wiring diagrams, block diagrams, and cables for the INControl. Connectors and Cables For most electronic engines, the INControl receives engine RPM, oil pressure, and coolant temperature data over the J1587 databus from the engine ECM. Some engines do not broadcast this data over the databus and sensors may need to be installed.
