PUMP GP-FUEL PRM & PRIM FILTER 1852069 - Caterpillar

TYPE="LEVEL" DEPTH="1" @@@--> 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 respective input to +Battery when a switch contact is opened or the harness has an open circuit. Closure of an OEM installed switch must short circuit the input to the -Battery common of the P14 ECM Connector. All switches are supplied by the OEM. If an undetermined problem is present, install an Electronic Service Tool and check the Electronic Service Tool Display Status screen indicating the switch status. Voltage thresholds measured at ECM: Voltage In Low Voltage In High > 3.5 VDC - With any switch contacts open, pin-to-pin leakage paths in connectors, harnesses, and switches must not result in an effective resistance of less than 5k Ohms from the respective control input to the Minus Battery Bus Bar or (P14, pin-21). OEM installed switches must be connected to the -Battery Bus Bar.Engine Synchronization Switch
The purpose of engine synchronization is to link multiple engine ECM's to a single vessel throttle. This feature adds operator convenience, vessel control, and is a standard practice in marine applications to provide for either throttle to be used in a backup situation. Engine synchronization can be transferred to either the PORT or STARBOARD throttle. The following code determines throttle synchronization. The synchronization function can only be activated and deactivated when both the PORT AND STARBOARD Desired Engine speeds are within 50 rpm of each other.Slow Vessel Mode
When the Slow Vessel Switch is activated (switched to -Battery), the ECM will reduce the programmed LOW IDLE speed to 550 rpm. This feature allows the operator better vessel maneuverability during docking and no-wake zones.Trolling Mode Input
During the Trolling Mode operation, the full range travel of the throttle lever will cause the engine speed to change from low idle engine speed to the maximum programmed trolling speed. The Trolling Mode will only engage when the engine speed is within 30 rpm of Low Idle. Trolling Mode can also be activated when the engine is not running.The Trolling Mode Switch Input is connected to -Battery Bus Bar when the Transmission is in Trolling Mode. The trolling valve activation MUST automatically connect the Trolling Mode Switch Input to the - Battery Bus Bar. Maximum trolling speed can be programmed to any value (rpm) from 900 to 1200 rpm. Remote Shutdown Switch
When the Remote Shutdown Switch is connected to -Battery Bus Bar (activated), the ECM disables the fuel solenoid. This action causes the engine to shut down while leaving the ECM powered and active to monitor all engine functions.
