24 V is output to the swing shut off solenoid (SOL:3) and the solenoid valve shifts. Pilot pressure enters both ends of the
swing section of the control valve, and the pilot pressure is then shut off instantly (spool of control V does not move).
b
After 5 seconds, 24V is output to the swing lock solenoid valve (SOL: 1) and the solenoid valve shifts. Oil within the brake
piston of the motor flows to the tank. The brake locks by torque at 100%.
