Instrument Panel - Elect. Cont. Later Engines How To Select Preset Operating Speeds (Bump Speeds) warns the operator if coolant temperature rises above the preset safe operating temperature. First select Turtle (Slow) or Adj by pressing speed select switch (J) to “Turtle” (slow) or “Adj”(center). Then you can press either the upper or lower portion of the bump speed enable switch (H) to unlock the setting. The bump speed enable must be held down as the speed select switch (J) is used to change the setting by pressing (+) to increase speed or (-) to decrease speed. N—Menu Key The menu key is pressed to either enter or exit the menu screens on the diagnostic gauge.
O—Arrow Keys Use the arrow keys (O) to change the display on the window of the diagnostic gauge and to access engine performance data. Once the slow idle speed has been set, the bump speed enable switch must be pressed and released three times within two seconds to commit the new operating speed to memory. If not done, the engine’s new speed will only be effective until the key switch is shut off. Then the speed will revert back to the previous setting. Pressing the left arrow to scroll to the left or upward or the right arrow to scroll to the right or downward. This will allow you to view various engine parameters and any diagnostic trouble codes that occur.
The fast idle speed is not adjustable. It will always go back to the factory preset fast idle speed. Refer to the following story for accessing engine information on the diagnostic gauge using the touch keys. K—Analog Throttle Control (Optional) P—Enter Key The throttle control (K) is used to control engine speed. This control is available only on engines with analog throttle. The enter key is pressed to select the parameter that is highlighted on the screen. Q—Amber “WARNING” Indicator Light L—Engine Oil Pressure Gauge When light comes on, an abnormal condition exists. It is not necessary to shutdown engine immediately, but problem should be corrected as soon as possible.
The oil pressure gauge (L) indicates engine oil pressure. An audible alarm (E) warns the operator if engine oil pressure falls below a safe operating pressure. R—Red “STOP ENGINE” Indicator Light M—Engine Coolant Temperature Gauge When light comes on, stop engine immediately or as soon as safely possible to prevent engine damage. Correct problem before restarting. The engine coolant temperature gauge (M) indicates engine coolant temperature. An audible alarm (E) OURGP11,000027C –19–25NOV03–3/3 17-3 021604 PN=66
