Minimum Maximum Default
700 rpm TEL rpm TEL rpm "PTO Cab Throttle RPM Limit"
The "PTO Cab Throttle RPM Limit" parameter defines the top engine rpm limit of the cab's accelerator pedal position sensor when the following conditions exist:
The "PTO Configuration" is programmed to "Cab Switches".
The PTO on/off switch is in the ON position.This parameter is intended to prevent engine overspeed when the dedicated PTO is used. This feature will have the following effect on PTO operation:
The cab controls are ignored if this parameter is programmed to "Low Idle".
The engine will operate to the top engine limit that has been programmed if this parameter is programmed to "TEL".
The engine will operate at the PTO top engine limit that has been programmed if the parameter is programmed to "PTO TEL".Note: "PTO Configuration" must be programmed to "Cab Switches" for this parameter to function. If "PTO Configuration" is programmed to "Remote Switches" or to "Remote Throttle", the ECM will always ignore the cab controls when the PTO on/off circuit is on.

Alternative Default
Low Idle
PTO TEL TEL "PTO Kickout Vehicle Speed Limit "
The "PTO Kickout Vehicle Speed Limit " parameter defines the maximum vehicle speed for setting or for maintaining a set engine rpm while the PTO is in operation. If the vehicle's speed signal exceeds this value, the engine will not maintain the set engine rpm.

2 km/h (1 mph) 204 km/h (127 mph) 2 km/h (1 mph) "Maximum PTO Vehicle Speed"
The "Maximum PTO Vehicle Speed" parameter specifies the maximum vehicle speed that is allowed when PTO mode is active. The engine will be derated in order to maintain this vehicle speed when the PTO mode is active.

Typical example
(1) Programmed torque limit The "Torque Limit" parameter defines the maximum torque output of the engine during operation of the PTO. This parameter provides temporary protection of equipment. The "Torque Limit" of the engine is active when the torque limit switch is in the ON position. The maximum value for this parameter is the rated torque of the engine. Programming a value higher than the rated torque is limited by the ECM. Refer to the graph in Illustration 1 for a typical example of the torque limit that is provided.

The "PTO Shutdown Time" parameter is the duration of continuous operation of the PTO. The timer will remain active only while there is no vehicle speed and the PTO on/off switch is in the ON position. The PTO shutdown timer will not activate until the engine exits cold mode operation.This parameter requires the "PTO Configuration" to be programmed to "Cab Switches", to "Remote Switches", or to "Remote Throttle" for the parameter to be programmed. The "Fan Control Type" parameter must also be programmed to "On/Off PWM",
