PRODUCT TOTAL PRESSURE GOVERNOR (TPG) BY AMS
Manual P/N 117684
5.2.9. SENSITIVITY (pressure sensitivity configuration)
This menu item allows configuration of the pressure mode sensitivity window. This window dictates how much
pressure difference must occur before the TPG adjusts the engine RPM to maintain the desired set pressure.
The display will show GOV± XX PSI. Use the INC and DEC switches to adjust the PSI value desired for the
pressure mode sensitivity.
Range = 4 PSI to 12 PSI (in 1 PSI steps). [default = 6 PSI]
5.2.10. SENSOR CAL (pressure sensor calibration)
This menu item allows calibration of the pressure sensor.
The display will show –SENSOR CAL-. See section 7.3 for the calibration procedure.
5.2.11. 1
st
MODE (first active mode configuration)
This menu item allows configuration of the governor mode active when the MODE switch is first pressed.
The display will show 1
st MODE=XXX. Use the INC and DEC switches to select the desired mode (PSI or RPM).
Proper interlocks must be established for the configured 1
st
mode to become active during operation.
Range = RPM (throttle mode) or PSI (pressure mode). [default = PSI]
5.2.12. AUTO MODE (pressure mode automatically entered on pump engagement)
This menu item allows configuration of automatically entering pressure mode when pump engagement occurs
(AUTO MODE?:Y). Note that this option will only be available if the 1
st
mode parameter (section 5.2.11) is set to
pressure mode (PSI). When this parameter is enabled, the governor will be put in pressure mode when the pump
is changed from a disengaged to an engaged position (interlocks permitting). Thereafter, when a user selects the
IDLE (standby) mode, the governor will remain in standby mode until a new mode is selected.
Range = Y1 (Automode ON, Throttle Ready first then Pump Engaged),
Y2 (Automode ON, Pump Engaged first then Throttle Ready),
N (Automode OFF).
[default = N]
5.2.13. COMM STATUS (view the CAN communication status)
This menu item allows viewing of the number of CAN messages per second and received errors. This menu item is
only available when the CAN message type is set to CFPG.
The display will show COMM STATUS. Use the INC and DEC switches to toggle between message per second
and received errors.
5.2.14. CONTROL (engine control message type)
This menu item allows configuration of the CAN or ANALOG control message type.
CFPG – Cummins Fire Pressure Governor, uses Cummins proprietary control message to control engine speed.
PGN0 – Uses J1939, PGN0 – Torque Speed Control message to control engine speed.
SCAN – SCANia, uses the Scania bodywork control message 1.
ANLG – Uses analog voltage signal to control remote throttle input on engine.
PWM – Uses pulse width modulation control signal (12-85%, 400 Hz).
VLVO – Uses Volvo specific PTO control commands for Volvo FE/FL series engines running through
a Volvo bodybuilder control module. This method should not be used when the TPG is directly
connected to the engine CAN bus. Volvo FM/FH series engines should use the standard PGN0
control mode and set the Engine ID variable to the address of the body builder module.
The display will show CONTROL=XXXX. Use the INC and DEC switches to adjust the control message type.
Range = CFPG, PGN0, SCAN, ANLG., PWM, VLVO [default = CFPG]
