Idle/PTO Vehicle Speed Limit
Maximum vehicle speed for setting or maintaining a set engine rpm in either idle or PTO mode. Idle mode is entered if the engine rpm is set using the cruise control On/Off switch along with Set/Resume. PTO mode is entered if the PTO On/Off switch is ON (uses Multi-Function Input #1). If the vehicle speed signal exceeds this value, the engine will not maintain the set engine rpm.
For AUG96 and later Personality Modules the Idle/PTO Vehicle Speed Limit has been separated into two parameters, Idle Vehicle Speed Limit (with range as below) and PTO Vehicle Speed Limit (refer to “PTO Vehicle Speed Limit (AUG96 and later Personality Modules)” on page 31).
Idle RPM Limit
Maximum engine rpm in idle mode. Idle mode occurs if the engine rpm is set using the cruise control On/Off switch and the Set/Resume switch. The actual high limit of this parameter is determined by the programmed Top Engine Limit. The lower limit is determined by the programmed Low Idle Engine RPM.
Programming this parameter to 600 rpm will prevent the engine from idling at a constant rpm above the programmed Low Idle rpm.
Idle/PTO RPM Ramp Rate
This parameter determines engine rpm rate of increase/decrease. This parameter determines Accel, Decel, and Resume Idle or PTO Engine rpm rates of increase/decrease. The parameter can be set to a value between 5 rpm and 1000 rpm inclusively in one rpm increments.
NOTE: The parameter applies to both idle control (rpm set using cruise control On/Off switch and Set/Resume) and PTO control (rpm set using PTO On/Off switch and Set/Resume).
Idle/PTO Bump RPM
Determines the rpm increment/decrement when the Accel/Decel switches are briefly toggled. It also applies to both dedicated PTO and idle. If a PTO Engine RPM Set Speed has been programmed the Idle/PTO Bump RPM applies only to engine rpm control initiated using the Cruise Control On/Off circuit not the PTO On/Off circuit.
Fast Idle RPM
Fast Idle RPM determines the preset Fast Idle engine rpm as controlled using the Fast Idle Enable Switch. This rpm can be overridden within its programmable range by the operator. To override, depress the accelerator pedal until the desired rpm is reached, and then depress the Fast Idle Enable Switch. This rpm will be the Fast Idle RPM as long as the ECM is powered up.
JUN95 and earlier Personality Modules
JUL95 and later Personality Modules
Fast Idle RPM #2 (AUG96 and later Personality Modules)
Fast Idle RPM #2 determines the second preset Fast Idle engine rpm as controlled using the Fast Idle Enable Switch. This rpm preset is disabled by programming it to 0.
The Fast Idle RPM Customer Parameter range is 700 – TEL rpm. The Fast Idle RPM #2 Customer Parameter range is 700 – TEL rpm with 0 rpm as the default. Following engine start up, depressing/toggling the Fast Idle Enable switch ramps the engine to the programmed Fast Idle RPM. If Fast Idle RPM #2 is programmed to 0 depressing/toggling the Fast Idle Enable switch will cause the engine to return to Low Idle. Depressing/toggling the Fast Idle Enable switch with Fast Idle RPM #2 programmed to a value greater than 0 will cause the engine to ramp to the programmed Fast Idle RPM #2. Depressing/toggling the Fast Idle Enable switch a third time will cause the engine to return to low idle. The engine ramps to the Fast Idle RPM, Fast Idle RPM #2, and Low Idle independent of the programmed Idle/PTO Ramp Rate.
