Features of the Dedicated PTO
There are several features of the dedicated PTO:
The dedicated PTO reduces the alteration of the cab wiring or the dedicated PTO eliminates the alteration of the cab wiring.
The dedicated PTO has multiple speed control by using the "PTO Engine RPM Set Speed A" and "PTO Engine RPM Set Speed B".
The dedicated PTO has two speed controls that require the PTO On/Off circuit.
The dedicated PTO provides three different PTO configurations which determine the operation of the dedicated PTO.
The dedicated PTO has one speed control that has a programmed low idle to PTO set speed for engine rpm with one circuit.
The dedicated PTO has two speed controls with three circuits. The three circuits are the "programmed low idle", the "PTO preset set speed", and the "PTO TEL".
The accelerator pedal in the cab can be disabled without altering the cab wiring.
The dedicated PTO provides an rpm limit for the accelerator pedal in the cab and the cab switches.
The dedicated PTO has additional inputs for the remote accelerator position sensor. The remote accelerator position sensor provides control of the engine rpm on the outside of the cab.
The dedicated PTO has additional Set/Resume inputs for control of the engine rpm. The inputs can be remote. An example would be outside of the cab.
"Engine set speeds" that are lower can be used to reduce the level of engine noise during dedicated PTO operation. "Engine set speeds" can be lower than a mechanical engine.
The ECM controlled Engine Retarder is disabled when the PTO On/Off switch is in the ON position.
The idle shutdown feature is disabled when the PTO On/Off switch is in the ON position.
The dedicated PTO provides a programmable "PTO shutdown time" in order to reduce driver abuse. Driver abuse is placing the truck in dedicated PTO mode in order to disable the "idle shutdown timer".
The cab clutch inputs and the service brake inputs can be prevented from disengaging an "engine set speed" during dedicated PTO operation. Slow moving vehicle operations require control of the engine rpm from the cab. An example would be a curb pouring cement truck.
The dedicated PTO provides a programmable "engine torque limit".
The dedicated PTO provides a programmable "engine rpm acceleration/deceleration ramp rate" and a programmable "engine rpm bump rate".
The dedicated PTO requires an OFF and ON transition of the PTO On/Off switch in order to begin dedicated PTO operation.
The dedicated PTO provides the ability to keep the ECM controlled cooling fan "ON" during dedicated PTO operation.Customer Programmable Parameter Options
There are many customer programmable parameter options:"PTO Configuration" - The "PTO Configuration" determines the input/output configuration that is used for the Dedicated PTO operation."PTO TEL" - The "PTO TEL" provides a parameter in order to limit the engine rpm during PTO operation."PTO Engine RPM Set Speed" - The "PTO Engine RPM Set Speed" provides a set point for the engine rpm for the PTO."PTO Engine RPM Set Speed A" - This provides a programmable engine speed set point that is actuated by a dedicated switch circuit. The dedicated switch circuit is Input 7."PTO Engine RPM Set Speed B" - This provides a second programmable engine speed set point that is actuated by a second dedicated switch circuit. The dedicated switch circuit is Input 19."PTO to Set Speed" - The "PTO to Set Speed" function requires only one circuit (PTO On/Off Switch) to provide two speed controls. The "PTO to Set Speed" function provides three-speed controls by using the PTO On/Off Switch and the Set/Resume Switch."PTO Cab Controls RPM Limit" - The "PTO Cab Controls RPM Limit" provides a parameter in order to limit the rpm from the accelerator pedal position sensor in the cab during PTO operation. The "PTO Cab Controls RPM Limit" can be used in order to exceed the programmed "PTO TEL" with the accelerator pedal that is in the cab."Torque Limit" - The "torque limit" reduces the engine torque during PTO operation. The "torque limit" will also reduce the engine torque when the Torque Limit Switch is in the ON position for temporary protection of equipment."PTO Vehicle Speed Limit" - The "PTO Vehicle Speed Limit" determines the operating range of the vehicle speed during PTO operation."Idle/PTO RPM Ramp Rate" - The "Idle/PTO RPM Ramp Rate" determines the rate of acceleration and deceleration."Idle/PTO Bump RPM" - The "Idle/PTO Bump RPM" determines the amount of change in the engine rpm when the Set/Resume Switch is toggled."PTO Shutdown Time" - The "PTO Shutdown Time" is a programmable time. If the engine is in PTO mode, then the "PTO Shutdown Time" will shut down the engine when the time limit expires."PTO Activates Cooling Fan" - The "PTO Activates Cooling Fan" can be programmed so that the cooling fan will operate during PTO operation."Input 4" - "Input 4" provides a parameter for a Torque Limit Switch when torque limiting is desired for temporary protection of equipment. This is regardless of the position of the PTO On/Off switch. MAR98 or later Personality Modules"Input 5" - "Input 5" provides a parameter for an Ignore Brake/Clutch Switch when mobile use of the vehicle is desired with a set engine rpm. The brake and the clutch are not required in order to disengage the engine rpm set speed. MAR98 or later Personality Modules"Input 7" - "Input 7" can be programmed to "PTO Engine RPM Set Speed A" in order to provide a dedicated circuit for the PTO operation at a programmed speed when the PTO On/Off Switch is ON. JUL99 or later Personality Modules"Input 19" - "Input 19" is programmable to "PTO Engine RPM Set Speed B" in order to provide a second dedicated circuit for the operation at a programmed speed when "PTO Engine RPM Set Speed A" is OFF and the PTO On/Off switch is ON. JUL99 or later Personality Modules"Torque Limit Switch" - The "torque limit switch" parameter limits torque regardless of PTO operation."Ignore Brake/Clutch Switch" - The "ignore brake/clutch switch" parameter allows mobile use of the vehicle during PTO operation. The "ignore brake/clutch switch" parameter allows mobile use of
