KIT-GASKET 3607477 - Caterpillar

All of the functions described in the following text are available or enhanced if the vessel OEM provides and installs the appropriate components. The components required for each feature are listed in the Installation Section of this guide.Throttle Position Sensor
The Throttle Position Sensor (TPS) eliminates the mechanical throttle and governor linkages (along with their inherent adjustments). The TPS utilizes operator lever movement and sends an electrical signal to the engine Electronic Control Module (ECM). The TPS signal, along with the speed/timing signal is processed by the ECM to control precise engine speed. The Throttle Position Sensor does not require separate circuit protection. It is protected by the ECM 15 amp circuit breaker. The sensor output is a constant frequency signal whose pulse width (duty cycle) varies with throttle position. The Pulse Width Modulated (PWM) signal is expressed as a percentage (percent duty cycle) as shown in the preceding chart.Transmission Oil Temperature Sensor
The ECM monitors Transmission Oil Temperature with the Transmission Oil Temperature Sensor. The sensor can measure temperatures up to 120°C (248°F). Torque specifications are 20 3 N m (15 2 lb ft). Transmission Oil Temperature is monitored and high Transmission Oil Temperature is detected with a programmable set point. The High Transmission oil Temperature set point can be programmed to any value from 50 to 120°C (122 to 248°F). If this parameter is programmed to 120°C (248°F), the Transmission Oil Temperature monitoring is disabled.Transmission Oil Pressure Sensor
The ECM monitors Transmission Oil Pressure with a sensor located on the high pressure side of the Transmission. The Transmission Oil Pressure Sensor can measure Transmission Oil Pressure from 0 kPa (0 psi) to 3100 kPa (442 psi). Torque specifications are 10 2 N m (7 1 lb ft). Transmission Oil Pressure is monitored and High Transmission Oil Pressure is detected with a programmable set point. The High Transmission Oil Pressure set point can be programmed to any value from 700 to 2963 kPa (100 to 400 psi). If the Marine Transmission Oil Pressure or Temperature parameters are programmed to NO, the monitoring and sensor diagnostics are disabled.Hourmeter
The ECM provides an hourmeter signal. When the ECM reads an engie rpm greater than 500 rpm, the ECM turns ON the hourmeter. This signal is actual engine running hours and is not an accurate measure of ECM hours.Tachometer
The ECM engine rpm signal is provided by the Engine Speed/Timing Sensor. The ECM uses this value to scale the engine speed into revolutions per minute for the tachometer. The selection of the pulses per revolution (ppr) for the tachometer is done through the Customer Programmable Parameter, Tachometer Calibration. Customer Installed Switches
Applied voltage to switches by the electronic control will normally not exceed 24 VDC. Contact plating should not corrode or oxidize. Gold plated contacts are recommended. Normal current draw through the switches by the control will not exceed 5.0 mA. Contact chatter and momentary opening or closing should not exceed 100 milliseconds in duration. ECM internal pull up voltages force the
