TORQUE CONVERTER GP 1T0725 - Caterpillar

Transmission Oil Temperature Sensor and Oil Pressure Sensor
Example of connecting the 100-3055 Transmission Temperature Sensor and the 3E6114 Transmission Oil Pressure Sensor.Connecting the Transmission Sensors and Customer Connector J19 (HD)
1. Install 100-3055 Transmission Temperature Sensor.2. Install 3E6114 Transmission Oil Pressure Sensor. Oil pressure sensor MUST be mounted in transmission oil cooler return line (to transmission).3. Connect from J19 Pin-1 to P19A Pin-A of the transmission temperature sensor.4. Connect from J19 Pin-2 to P19A Pin-B of the transmission temperature sensor.5. Connect from J19 Pin-3 to P19A Pin-C of the transmission temperature sensor.6. Connect from J19 Pin-4 to P19B Pin-A of the transmission oil pressure sensor.7. Connect from J19 Pin-5 to P19B Pin-B of the transmission oil pressure sensor.8. Connect from J19 Pin-6 to P19B Pin-C of the transmission oil pressure sensor. Refer to Customer Specified Parameters, in this instruction, for selecting the high temperature oil temperature and pressure set points.Trolling Mode
Trolling Mode Connection. There is no actual (physical) switch. Connection to (-)Battery should be made automatically when trolling valve is activated.When the marine gear is in Trolling Mode, the trolling valve activation MUST automatically connect to (-)Battery Bus Bar, which will limit engine speed to programmed value (from 900 to 1200 rpm). Connect (-)Battery Bus Bar through the trolling valve to Pin-8 (Trolling Mode) of the J1 Customer Connector.Programming the Trolling Mode
Maximum trolling speed can be programmed using a Caterpillar Electronic Control Analyzer Programmer (ECAP) Service Tool.Refer to Customer Specified Parameters in this publication, SENR6500 Electronic Troubleshooting Manual (from SENR6505 Service Manual) and SEHS9199 Tool Operating Manual for NEXG4516 Marine Engine Functions Service Program Module (SPM).Slow Vessel Switch
When the switch is activated, the ECM will limit engine speed to idle below programmed LOW IDLE speed. During this mode of operation, the idle speed will drop to 550 rpm to allow pilot better vessel maneuverability during docking or no-wake zones.
Slow Vessel Switch Connection.1. Connect (-)Battery Bus Bar to the normally open (N/O) contact of the Slow Vessel Switch.2. Connect from Pin-19 (Slow Vessel) of J1 Customer Connector to the common contact of the Slow Vessel Switch.Maintenance Clear Switch
The Maintenance Clear Switch is required to reset the maintenance indicator diagnostic after engine maintenance has been performed.
Maintenance Clear Switch Connection.1. Connect from (-)Battery Bus Bar to the normally open (N/O) contact of the Maintenance Clear Switch.2. Connect from Pin-20 of J1 Customer Connector to the Common of the Maintenance Clear Switch.Remote Tachometer Installation
Remote Tachometer Connection Schematic.1. Connect from J1 Customer Connector Pin-17 to Signal Input 1 of the Tachometer.2. Connect from J1 Customer Connector Pin-11 to Signal Input 2 of the Tachometer. Either one of the two signal lines from the ECM can be used for tachometers with a single input terminal. The remaining line should be left disconnected.3. Connect from (+)Battery Bus Bar to the (+)Battery input of the Tachometer.4. Connect from (-)Battery Bus Bar to the (-)Battery input of the Tachometer.5. Connect an ECAP to the J4 ATA data link Connector and proceed to the Customer Parameters Screen. Calibrate the
