"PTO Configuration"
The "PTO Configuration" parameter determines the features that are available and the input signals that are used for dedicated PTO applications. If this parameter is programmed to "Off", the Engine Control Module (ECM) does not use the following configurations for the PTO. In order for the ECM to utilize the remaining parameters that are used for the PTO configuration, a PTO on/off circuit must be connected to J1/P1-56 Input #1 of the ECM. Also connect a PTO switch on lamp to J1/P1-30 Output #1 of the ECM .If the "PTO Configuration" parameter is programmed to "Cab Switches", the ECM will use the signals from the following two cab switches for PTO and cruise control:
J1/P1-35 PTO set switch
J1/P1-44 PTO resume switchIf the "PTO Configuration" parameter is programmed to "Remote Switches", the ECM will monitor the inputs that have been programmed for the remote control switches. All cab switches that are used for PTO control will be ignored when the PTO on/off circuit is on.If the "PTO Configuration" parameter is programmed to "Remote Throttle", the ECM will monitor J1/P1-68 Input #8 for the remote throttle input. The ECM will monitor the inputs that have been programmed for the remote control switches. All cab switches for the PTO control will be ignored when the PTO on/off circuit is on.

Remote Throttle Off "PTO Top Engine Limit"
The "PTO Top Engine Limit" is the top engine limit that is available during PTO operation.Note: The "PTO Configuration" parameter must be programmed to "Cab Switches", to "Remote Switches", or to "Remote Throttle" before this parameter can be programmed.

Minimum Maximum Default
700 TEL rpm TEL rpm "PTO Engine RPM Set Speed"
The "PTO Engine RPM Set Speed" parameter defines a preset value for the engine speed during PTO operation. The engine will proceed to this speed when the PTO on/off circuit is turned on or after the PTO set switch is actuated one time.The "PTO Configuration" parameter must be programmed to "Cab Switches" or to "Remote Switches" for this parameter to be enabled.Consider the following operational conditions during the setup of this parameter:
This parameter must be programmed higher than the programmed low idle of the engine.
If the "PTO to Set Speed" is programmed to a higher value than the "PTO Top Engine Limit", the set speed will be limited by the lower "PTO Top Engine Limit".
In order for the PTO to operate at one rpm set speed above the engine's low idle, program the "PTO Top Engine Limit" to the same rpm as the "PTO Engine RPM Set Speed".
In order for the PTO to operate at two rpm set speeds above the engine's low idle, program this parameter to some intermediate value between the low idle setting and the "PTO Top Engine Limit".To operate the PTO in the above example, place the PTO on/off switch to the ON position. Toggle the set switch once in order to cause the rpm to advance to the "PTO Engine RPM Set Speed". Toggle the set switch
