Engine Speed Dial Switch
Illustration 1 g00629971
Engine Speed Dial Switch (1) Switch (2) SchematicThe Machine ECM converts a signal of the Engine Speed Dial into a pulse width modulated (PWM) signal. The Engine ECM receives the PWM signal in order to control the engine speed at 10 stages. The position of the Engine Speed Dial is indicated on the display of the Monitoring System.Soft Switch Panel

Right Joystick (2-Button, Trigger Switch) (1) Free (SW-1) (2) Boom Float Disable/Magnet On (SW-2) (3) Low Idle Switch (SW-3)The one touch low idle switch (3) is located on the right joystick handle (See Illustrations 3). The one touch low idle switch will automatically reduce engine speed to 1020 RPM. Both joystick handles (LH and RH) must be in the neutral position before the engine speed is reduced.Pressure Switch

These pressure switches will monitor the hydraulic system. This switch is normally open. These switches will inform the controller about the status of the hydraulic demands. When there is no hydraulic demand these switches are open. The function of the automatic engine speed control (ECM) of the controller will use these switches to determine control of the engine speed and control of the pump.Key Start Switch
Illustration 6 g00291705
Key Start SwitchThe key start switch is an input of the engine and pump controller. The key start switch informs the ECM of an attempt to start the engine. Then, the ECM initiates the start procedure.During normal machine operation, the start terminal of the key start switch is open. If the key start switch is placed in the START position the start terminal will close. +Battery voltage is supplied to the start terminal. When all starting conditions are satisfied, the ECM sends a +battery signal to the start relay and engine cranking begins.Note: After the key start switch is initially turned to the START position, the switch will not return to the START position from the ON position. The switch must be turned to the OFF position first. Then, the switch can be turned to the START position.Toggle Switch
