Solenoid Valve (Implement Lockout)
The implement lockout solenoid is designed to prevent the movement of the blade and the ripper. The flow of oil through the implement pilot manifold is blocked when the solenoid is de-energized. The movement of the ripper solenoid or the blade solenoid will have no effect, if the oil is not flowing. The operator will use the implement lockout switch in order to energize the solenoid valve or the switch is used to de-energize the solenoid valve. The implement lockout solenoid does not affect the pin puller attachment. The switch affects the system in the following manner:LOCKED - The solenoid is de-energized. The implement system is no longer operable. UNLOCKED - The solenoid is energized. The implement system is enabled.The implement lockout solenoid is an on/off type of solenoid. The ECM provides +battery power to the solenoid via the implement lockout switch. The coil resistance of the solenoid valve is approximately 20 ohms at room temperature. The ECM will detect a circuit failure and the ECM will log a CID 0882 when the failure is present.

Each of these solenoid valves is designed to control the flow of oil to the hydraulic system. These solenoids control the height of the blade, the tilt of the blade, the height of the ripper and the tilt of the ripper. The ECM will adjust the solenoid valves according to the request that is made by the operator. This request is through the blade control handle or the ripper control handle. These solenoid valves are the proportional type of solenoid valve. The ECM uses a pulse width modulated signal (PWM) in order to vary the current to the solenoid. The solenoid will receive electrical current from the ECM. The solenoid plunger will travel a distance that is in proportion to the electrical current that is being sent from the ECM. The electrical current to the solenoid will control the position of the valve. The coil resistance of the solenoid valve is approximately 27 ohms at room temperature. The ECM can detect a failure in the solenoid circuit and the ECM will record a diagnostic code when a failure is present.Note: The solenoid coils are not designed to operate using 24 DCV directly. The ECM sends a PWM signal of 24 V at a duty cycle that will provide the necessary current to the solenoid coils. Do NOT activate the coils by using 24 DCV (+battery). The life of the coils will be reduced drastically. A source of 12 DCV should be used, if
