Medium-Duty Dual Clutch - PTO Inputs and Configurations
Power Take-Off (PTO)
•
PTO must be enabled within the software for PTO functionality. Contact dealer for more information.
•
The Eaton Procision Transmission is designed to provide an enhanced acknowledgment for PTO applica-
tions. Procision TCM will receive a “PTO Request” from the vehicle to enter into a PTO mode. If the TCM
deems that conditions are suitable for PTO operations, the TCM will supply a “PTO Engage” output to allow
the PTO engagement. A confirmation from the PTO returns to the TCM via the “PTO Confirm” line to com-
plete the loop. The Procision TCM has the functionality to support two PTOs at the same time (one direct
wire control and one over the J-1939 network).
•
PTO operation requires a single pole double 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 both 12-volt and 24-volt
vehicle systems.
•
The TCM Engage circuit load shall draw no more than 0.50 amps with 16 volts applied for a 12 volt vehicle
system or 32 volts applied for a 24 volt system.
•
An 18 AWG TXL cable is required at the TCM 20-way connector for sealing purposes.
•
The Procision TCM will also support PTO request via SAE J-1939 protocol.
