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 the discharge pressure transducer’s range (0 to 300 PSI, or 0 to 600 PSI).
The display will show XDCR= XXXPSI. Use the INC and DEC switches to adjust the value desired for the pressure
change per button press.
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.
Refer to the menu level tables for the default values (section 5.2).
5.2.25. POC ASSERT (Power On Cycle assertion)
This menu item allows enabling/disabling of the analog control signal idle voltage assertion at power-up. When the
POC ASSERT is enabled the analog control signal will be set to the configured idle voltage at the start of the TPG’s
power cycle. If the POC ASSERT is disabled the analog control signal will be set to the minimum configured level
at the start of the TPG’s power cycle.
The display will show POC ASSERT:X. Use the INC and DEC switches to select Y or N.
Range = Y (enabled) or N (disabled). [default = N]
5.2.26. 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.
The display will show GOV GAIN :XX. Use the INC and DEC switches to adjust the value.
Range = 0 to 35 [default = 15]
5.2.27. 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 X PSI/STEP. Use the INC and DEC switches to adjust the value.
Range = 1 to 5 [default = 3 PSI/STEP]
