ELECTRONIC TROLL PROCESSOR
ELECTRONIC TROLL PROCESSOR (ETP) INSTALLATION 256-4883
When the transmission is equipped with an optional electronic troll valve, the ETP will provide the trolling interface between the Powertrain Control Processor (PCP) and the electronic transmission. The ETP is responsible for providing the trolling signals to either Twin Disc or ZF electronic transmissions. The ETP receives the troll command (% slip) from the PCP, converts the message into a current/voltage and controls the transmission troll valves accordingly. The ETP also measures the shaft speed and transmits it on the J1939 data link to be displayed on the MPD.
