PTO Interface
Endurant - PTO Inputs and Configurations
The Endurant transmission is designed to provide an enhanced acknowledgment for PTO applications.
•
PTO operation requires a double pole single throw switch.
•
Consult PTO manufacturer for power requirements needed for fuses, switches and wires on PTO circuitry.
•
TCM request and confirmation circuit lines will provide 1 milliamp of current for a 12-volt systems.
•
The TCM engage circuit load shall draw no more than 0.50 amps with 16 volts applied for a 12 volt vehicle system.
•
An 18 AWG TXL cable is required at the TCM 20-way connector for sealing purposes.
•
The Transmission will support a J1939 PTO operation, Hardwired PTO operation and J1939/Hardwired operation.
•
Examples of the three different types of integration are shown below.
PTO System Engagement Sequence
Note:
This is not an operator sequence.
1.
The TCM will receive a “PTO request” from the vehicle to enter into a PTO mode.
2.
If the TCM conditions are validated for PTO operations.
3.
The TCM will supply a “PTO engage” output to allow the PTO engagement.
4.
A confirmation from the PTO returns to the TCM via the “PTO confirm” line to complete the circuit.
Note:
The TCM has the functionality to support two PTOs at the same time - one direct wire control and one over the J1939 net-
work.
Endurant Auto Neutral Feature
An auto neutral feature is provided with this transmission which forces the transmission into neutral in all instances when the
parking brake is applied. The Endurant system requires the use of the Park Brake Switch signal in the J1939 CCVS1 message to
enable function of the Auto Neutral feature.
