Bail Solenoid
Illustration 18 g03423744The bail solenoid is an on/off type solenoid that controls the operation of the bail cylinder. The ECM sends a signal to energize or de-energize the solenoid depending on operator request. When the solenoid is energized, the bail cylinder moves to connect to a second machine.Cushion Hitch Enable Solenoid
Illustration 19 g03425512The cushion hitch enable solenoid is an on/off type solenoid. The ECM energizes the solenoid based on operator request. When the solenoid is energized, the cushion hitch system is activated.Proportional Solenoids
Illustration 20 g03347475All proportional solenoids in the implement system are identical in construction, however function differently. Illustration 20 shows an example of a proportional solenoid in the implement system.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 the coils must be activated by not using the ECM. Bowl Raise/Lower Solenoids
There are two solenoids controlling bowl height. There is a bowl raise and lower solenoid. The two solenoids are identical in construction, and together control the operation of the bowl raise/lower spool. The solenoids are proportional solenoids, and if the ECM sends a higher duty cycle signal to the bowl raise solenoid, that solenoid shifts the spool further in the RAISE position. If the ECM sends a higher duty cycle signal to the bowl lower solenoid, that solenoid shifts the spool further in the LOWER position. The two solenoids operate together to control the movement of the bowl raise/lower spool.Ejector Forward/Return Solenoids
There are two solenoids controlling ejector position. There is an ejector forward and return solenoid. The two solenoids are identical in construction, and together control the operation of the ejector forward/return spool. The solenoids are proportional solenoids, and if the ECM sends a higher duty cycle signal to the ejector forward solenoid, that solenoid shifts the spool further in the FORWARD position. If the ECM sends a higher duty cycle signal to the ejector return solenoid, that solenoid shifts the spool further in the RETURN position. The two solenoids operate together to control the movement of the ejector forward/return spool.Apron Raise/Lower Solenoids
There are two solenoids controlling apron height. There is an apron raise and lower solenoid. The two solenoids are identical in construction, and together control the operation of the apron raise/lower spool. The solenoids are proportional solenoids, and if the ECM sends a higher duty cycle signal to the apron raise solenoid, that solenoid shifts the spool further in the RAISE position. If the ECM sends a higher duty cycle signal to the apron lower solenoid, that solenoid shifts the spool further in the LOWER position. The two solenoids operate together to control the movement of the apron raise/lower spool.Cushion Hitch Leveling Solenoid
The cushion hitch leveling solenoid controls the movement of the
