CYLINDER GP-BLADE 3741857 - Caterpillar

Menu D - Display Menu
Input and output values are displayed once when each item is selected. To get a continuous update, hold down the up or down arrow. Descriptions of each menu item follow.1. Engine Speed displays the current engine speed in rpm.2. Speed Reference displays the current speed reference in rpm. Note that this may not be the speed the engine is currently running at due to the effect of idle droop, fuel limiters, etc.3. Actuator Output displays the current percent of output. Maximum (100%) is 200 mA (0 mA for reverse-acting). This is useful for setup of the control fuel limiters, torque limiter, idle droop, and gain breakpoint settings.4. Aux Output displays the milliamps on the Aux Output. This is useful for testing and system calibration.5. Remote Input displays the milliamps on the Remote Speed Setting Input. This is useful for testing and system calibration.6. Aux Input displays the voltage on the Aux Input.7. Run/Stop Switch Status displays the status of discrete input A, terminal 9. Closed indicates 24 Vdc is applied to the input selecting the run position. Open selects minimum fuel or the stop position.8. Idle/Rated Switch Status displays the status of discrete input B, terminal 10. Closed indicates 24 Vdc is applied to the input selecting rated speed and the maximum fuel limit and the torque limit. Open indicates idle and the start fuel limit are selected.9. Lower Switch Status displays the status of discrete input C, terminal 11. Closed indicates 24 Vdc is applied to the input selecting lower speed (or remote speed setting if the Raise switch is also closed).10. Raise Switch Status displays the status of discrete input D, terminal 12. Closed indicates 24 Vdc is applied to the input selecting raise speed (or remote speed setting if the Lower switch is also closed).

Figure 4-6b. Six-Breakpoint Torque Limiter (9905-457)11. Local/Remote Switch Status displays the status of both discrete inputs C and D, terminals 11 and 12. Selecting both Raise and Lower places the control in the remote speed setting mode where the 4-20 mA Remote Speed Setting Input is used for the speed reference.12. Alternate Dynamics Switch Status displays the status of discrete input E, terminal 13. Closed indicates 24 Vdc is applied to the input selecting the alternate dynamics (dynamics 2).13. Failed Speed Override Switch Status displays the status of discrete input F, terminal 14. Closed indicates 24 Vdc is applied to the input selecting to override the function of the failed speed detection which provides for moving fuel to minimum position when no speed signal is detected by the control.14. Watchdog Status displays the status of the control CPU. The normal status displayed is CPU OK. If a CPU fault occurs, the CPU OK indicator on the front of the control will turn off, the Actuator Output and Aux Output will decrease to minimum output, and the Watchdog Status will display TIME OUT. To reset the watchdog, turn off power to
