INSTALLATION
Mount the TPG+ on the operator’s panel with four #10 screws.
The dimensions in the detail below are in inches [millimeters].
WIRING HARNESS
The main system harness (p/n 118453) is comprised of a pair of harnesses:
the power/communication harness (depicted below in blue) and the signals
harness (depicted below in green).
For the analog control option, add harness wires (p/n 118454) depicted in
red.
DISCHARGE PRESSURE TRANSDUCER INSTALLATION
Install the 300 psi (2068 kPa, 20 bar) discharge pressure
transducer (p/n 113557) on the discharge side of the pump.
The pressure connection is a ¼-18 NPT male port. A ‘T’ fitting
can be used to share the pressure gauge outlet on the
discharge manifold.
INTAKE PRESSURE TRANSDUCER INSTALLATION
Install the 300 psi (2068 kPa, 20 bar) intake pressure
transducer (p/n 113557) on the intake side of the pump. The
pressure connection is a ¼-18 NPT male port.
VERIFY ENGINE RPM
Verify proper J1939 CAN connection to the engine’s ECM by
monitoring the RPM display of the TPG+ while the engine is
running. The display should show accurate RPM information.
VERIFY INTERLOCKS
The TPG+ requires OEM provided interlocks THROTTLE READY and PUMP ENGAGED for proper operation. The TPG+ utilizes backlit text to
indicate interlock status. The interlock status indicators are located directly beneath the switch panel.
Activate the throttle ready interlock. (Apply system power to pin 2 of connector C4).
Verify the THROTTLE READY text illuminates.
► The TPG+ will operate in RPM mode only and cannot be changed to pressure mode.
Activate the pump engaged interlock. (Apply system power to pin 10 of connector C4).
Verify the PUMP ENGAGED text illuminates.
► The TPG+ will not operate in any mode without the THROTTLE READY interlock.
Activate the throttle ready and pump engaged interlocks. (Apply system power to pins 2
and 10 of connector C4).
Verify the PUMP ENGAGED, OKAY TO PUMP, and THROTTLE READY text
illuminates.
► The TPG+ will operate in either mode.

Verify J1939 CAN connection by monitoring accurate RPM display on TPG+ while engine is running.

Verify Interlocks

Required Interlocks

TPG+ requires THROTTLE READY and PUMP ENGAGED interlocks for operation, indicated by backlit text.

Verify Throttle Ready Interlock

Activate throttle ready interlock (power pin 2, C4) and verify THROTTLE READY text illuminates.

Verify Pump Engaged Interlock

Activate pump engaged interlock (power pin 10, C4) and verify PUMP ENGAGED text illuminates.

Verify Combined Interlocks

Activate both interlocks (pins 2 & 10, C4) and verify PUMP ENGAGED, OKAY TO PUMP, THROTTLE READY text.

Zero Calibrate Discharge Pressure Transducer

Discharge Pressure Calibration Need

TPG+ reading may not be '0' at zero pressure due to ambient factors.

Discharge Pressure Zero Calibration Procedure

Procedure to zero calibrate discharge pressure transducer using IDLE, MENU, SILENCE, and INC switches.

Verify Engine Control

Verify Interlock Illumination

Activate throttle ready and pump engaged interlocks and verify PUMP ENGAGED, OKAY TO PUMP, THROTTLE READY text.

Pressure Mode Operation

Press MODE switch to show GOV=PRESSURE. PSI indicator illuminates YELLOW.

Throttle Mode Operation

Press MODE switch to show GOV=THROTTLE. RPM indicator illuminates BLUE.

RPM Adjustment

Engine RPM changes when pressing INC or DEC switches.

Idle Operation

Press IDLE switch to show IDLE and reduce engine RPM to idle speed.

Attention Ford F-Series Customers

Accelerator;Brake Pedal Warning
