Manual P/N 118711
5.2.22. WARNINGS (data monitor warning configuration)
This menu item allows configuration of the source for engine warnings. Warnings can be determined by engine
diagnostic messages (DM1 messages) over the data bus (
Bus), or at setpoints defined by the user based on J1939
oil pressure and engine temperature data ( Usr).
The preferred and most accurate method is to use Bus warnings from the engine diagnostic system. Note that not
all engines support this feature, contact Class1 customer support for more information.
Range = Bus (bus controlled) or Usr (user configured). [default = Bus]
When the Usr configuration is selected the following setpoints will be assigned next.
A. WARN º F (U SER DEFINED ENGINE TEMPERATURE HIGH WARNING - Y ELLOW LED)
B. CRIT º F (U SER DEFINED ENGINE TEMPERATURE HIGH CRITICAL - R ED LED)
C. WARN PSI (U SER DEFINED OIL PRESSURE LOW WARNING - Y ELLOW LED)
D. CRIT PSI (U SER DEFINED OIL PRESSURE LOW CRITICAL - R ED LED)
5.2.23. XDUCR (discharge pressure transducer range)
This menu item allows configuration of the intake/discharge pressure transducers installed as 300-PSI or 600PSI
sensors.
The display will show
XDCR= XXXPSI. Use the INC and DEC switches to select the transducer type.
Range = 300 PSI or 600 PSI. [default = 300 PSI]
5.2.24. FACTORY DFLT (Set factory defaults)
This menu item allows setting the TPG back to the factory defaults.
The display will show
FACTORY DFLT. Press the PRESET switch to load the defaults.
5.2.25. GOV GAIN (RPM change per step)
This menu item allows configuration of the RPM change per step. A larger number changes the RPM more with
each
INC or DEC switch press.
Note: Option only available with the Analog control type. This parameter is automatically set by the TPG+ when
the Auto Scale routine is run (see section 6.5 for more information).
The display will show
GOV GAIN :XX. Use the INC and DEC switches to adjust the value.
Range = 0 to 35 [default = 15]
5.2.26. PRESS GAIN (PSI change per step)
This menu item allows configuration of the psi change per step. A larger number changes the PSI more with each
INC or DEC switch press.
The display will show
PRESS GAIN. Press the INC or DEC keys to change the display to X PSI/STEP. Use the
INC and DEC switches to adjust the value.
Range = 1 to 5 [default = 3 PSI/STEP]
5.2.27. DITHER (Engine handshake)
This menu item allows enabling/disabling of engine handshake. Some engines require constant RPM modification
in order to maintain remote RPM control. When enabled, the TPG will vary the engine speed +/- 5 RPM around the
desired engine speed.
The display will show
DITHER=X. Use the INC and DEC switches to select Y or N.
Range = Y (enabled) or N (disabled). [default = N]
