The “+/–(SET)” button, 2, adjusts the cruise setting. When cruise mode is activated, the engine returns to the last cruise setting, if possible, based on throttle lever position. The cruise function can be set to any engine RPM, but the operating cruise RPM cannot exceed the normal RPM for the current throttle position. For example, if the cruise setting is 1800 RPM but the hand throttle is at a normal 1700 RPM position, cruise will not increase the RPM. On the 2360/2425 models equipped with the N14 the operating cruise RPM always stays about 100 RPM under the normal throttle position RPM. On the models, 2290, 2335 and 2375 equipped with the QSM 11 the cruise RPM is always less than or equal to the normal throttle RPM. Setting -Move the throttle handle higher than the desired cruise setting and press the “CRUISE” button, 1, to enter cruise operation. On the QSM 11 engine cruise will not engage unless the throttle is set to a higher operating speed than the previous set point. The engine speed will go to the RPM of the cruise setting. Adjust the cruise setting with the “+/–(SET)” button, 2. Set the cruise mode with the throttle lever at Full Throttle (throttle lever fully forward) whenever possible. Cruise function will disengage if the cruise RPM is set to a value equal to the throttle position RPM- --moving the throttle to a higher position will return cruise function. Figure2-37 12 Figure 2-38 2-26 SECTION 2 -OPERATION The “+/–(SET)” button will change the setting 10 RPM per momentary push. When the button is held down, the RPM will continue to move up or down. However, the dash RPM display will not keep up with RPM changes when the button is held down. In this case, it is advisable to estimate the setting by ear, wait for the dash to catch up, and fine tune the RPM using momentary pushes. It is never possible to set the cruise higher than the current throttle lever position. If the last cruise setting was above the throttle position, the system will remember that cruise setting unless the “+/–(SET)” button is pressed in cruise mode. The cruise RPM will return to the stored cruise setting if the throttle is moved above that RPM. The electronic system remembers the current cruise control setting at all times. The cruise setting remains in memory after the cruise switch is turned off, after the engine is shut off, or if the batteries are disconnected. Alternate Engine Speed Overrun -All N14 engines in 2360 and 2425 tractors have a rated engine speed of 2100 RPM. Actual high engine speed, when the throttle lever is placed in the full forward position, is 2225 +/- --50 RPM. The difference between the rated speed and the actual full throttle speed (125 RPM) is called throttle overrun (or sometimes referred to as high speed droop). The 125 RPM results in a 6% overrun (125 RPM . by 2225 RPM = 0.06 x 100%) of the engine in normal loaded operating conditions when tractor ground speed is below approximately 18.5 KPH (11.5 MPH). In situations where engine load is minimal and tractor ground speed is high above 18.5 KPH (above 11.5 MPH), the Electronic Engine Control System will progress to an alternate engine speed overrun condition. The full throttle overrun will now be 15% (2450 +/- --50 RPM) instead of the normal 6% (2225 +/- --50 RPM). An example of this would be a tractor traveling at 12.9 KPH (8 MPH), over the road, with the throttle lever fully forward and the cruise switch in the OFF position. Maximum engine RPM shown on the EICS of the tractor will be 2225 +/- -50 RPM. If the transmission is shifted into a higher gear and ground speed increases above 18.5 KPH (11.5 MPH), the engine will accelerate to a new higher speed, with the EICS now displaying a maximum engine speed of 2450 +/- --50 RPM. The alternative engine speed overrun feature of the electronic engine controls provide a higher ground speed when traveling over the road with the tractor. If tractor ground speed is reduced below 18.5 KPH (11.5 MPH), the system will revert to the 6% normal overrun mode. IMPORTANT: Loads placed on the engine while roading (implements, road grade) will affect tractor ground speed and the alternate speed overrun feature. 2-27 SECTION 2 -OPERATION Deceleration (manual or pedal) -When in cruise mode and hand throttle, 1, moves lower than the cruise setting, the cruise RPM decreases as well and stays 100 RPM less than the normal RPM for that throttle position. The RPM will increase back up to the cruise setting if the throttle handle is moved forward again. Example: With the throttle handle at Full Throttle, the cruise is set to 1800 RPM. When the throttle handle is moved back past the normal 1800 RPM position, the cruise speed will drop to 1700 RPM and continue to decrease as the throttle decreases. When the handle moves back up to full throttle, the cruise speed increases until it reaches 1800 RPM again. Using the deceleration pedal in cruise mode works the same as moving the throttle handle. If the deceleration pedal caus...
