SOLENOID VALVE INSTALLATION Insert suitable fittings and dowty seals to solenoid valve. Mount solenoid valve in a safe and dry position close to the main hydraulic pump. Locate a pipe between the hydraulic oil tank and solenoid valve (Port T) for the return of hydraulic oil. Ports A & B on the solenoid valve must be attached to the hydraulic pipes that have been cable tied to the boom. (pipe A to close coupler, pipe B to open coupler) Locate maximum pump pressure via test port or tap into main pressure pipe between pump and valve bank on the crown cylinder circuit. A restrictor is supplied that must be fitted between the pump and port P on solenoid valve. ELECTRICAL INSTALLATION Find a safe position in the cab to install switch and buzzer. (This must be located where it can not be accidentally activated. ) Always fuse live supply with 10-amp fuse. Activate switch & put hydraulic system under pressure by continuing to extend crowd cylinder. Only when the switch is in the on position should the buzzer sound and power allowed to energize the solenoid valve which will put the coupler in the open position. When the switch is in the off position the solenoid should have no electric current running to it and the coupler will return to the closed position. Open and close the coupler several times to assist air bleed from the system.
