HOSE-HYDRAULIC 1884654 - Caterpillar

function is a tool that is used as an aid for managers and maintenance personnel. This function allows tracking of the history of the machine. The ECM stores the data from significant events. This information is available through the ET service tool and the Caterpillar Monitoring System.The events that are recorded are listed below.Shift Counter - The counter records the number of transmission shifts from each gear to any other gear. The maximum number of records is 1.28 million. A record is created when the position of the transmission gear switch changes and stays in the new position for at least 0.5 seconds. The information that is collected by the counter is for the office. The information can be used in order to create a history of the shift patterns. The information can also be used for comparison purposes to predict repairs before the failure and set maintenance schedules.Lockup Clutch Counter - This counter records the number of shifts into direct drive. The maximum number of shifts that can be recorded is 12 million. The information that is collected by the counter is for the office. The information can also be used for comparison purposes to predict repairs before the failure and set maintenance schedules.Coasting in Neutral Counter - This counter records the number of occurrences when the speed of the machine is greater than 19.3 km/h (12 mph) with the transmission in the neutral positionLoad Count- This counter records the number of loads that are carried during a specific period. A count occurs if the body is up for 10 seconds or more.Total Load Count- This counter records the total number of loads that have been carried by the machine. The total number of loads are since the machine was new or the ECM was replaced. A count occurs if the body is up for 10 seconds or more.Transmission Abuse- This tattletale occurs when the operator shifts from NEUTRAL into FORWARD or REVERSE with the engine speed above 1500 rpm.Machine Overspeed- This tattletale occurs when the operator shifts to the maximum gear with engine speed at the following rpm:
2100 rpm (3500 engines)
2250 rpm (C175 engines)
2475 rpm (3400 engines)A machine overspeed event is recorded if engine speed exceeds the following rpm:
2300 rpm (3500 engines)
2400 rpm (C175 engines)
2675 rpm (3400 engines)
