Soft Detents
The soft detents in the joystick control or levers are mechanical, but the detents do not latch. The detents for the joystick control are controlled by the software within the implement (ECM). As the joystick control is moved into the detent position, the linkage will travel to a kickout position that is preprogrammed. The joystick should be released to the HOLD position. The linkage movement will continue until the kickout is reached. Any 6° movement of the joystick control from the HOLD position will override the detents. The kickouts will not be activated if the joystick control is held in the detent position for more that 1 second. If the control is not returned to the HOLD position within 0.75 seconds, then the kickout will not continue.Rotary Position Sensor (Lift Linkage)
Illustration 7 g00799209The lift linkage position sensor is an input to the implement ECM. The sensors continuously communicate the lift linkage position to the ECM. The ECM changes the position of the lift linkage by activating the lift lower solenoid and the lift raise solenoid. The changes are based on the position of the lift lever. The ECM uses the input from the sensor (lift linkage) in order to control the lift kickouts. The ECM uses the sensor input to cushion the lift linkage stops. The auto dig feature will also use the position sensor in order to position the work tool. The position sensor has one input connection to the ECM at connector contact J2-24.The lift linkage position sensor is a pulse width modulated sensor (PWM). Pulse width modulated sensors have a duty cycle signal that varies as the condition changes. The sensor continuously generates a PWM signal.
