When Connecting or disconnecting the Auto Coupler, use the central position to shut off the hydraulic pressure supply. This minimizes the reaction force generated by Auto Coupler. In addition, when there is a possibility that back pressure is generated at the T port due to the System, install a check valve for preventing back flow having a cracking pressure of 0.04 MPa or less in the position with*. (Otherwise, oil leakage from the tip of the socket or malfunction of the pilot may occur.) 2l Lock opération procédure 1. In the connected condition, supply the pilot circuit with hydraulic pressure, and open the check valve of the plug.

(Valve©opération) Controlling single action circuit J] When Connecting or disconnecting the Auto Coupler, shut off the hydraulic pressure supply to the hydraulic jig circuit. This minimizes the reaction force generated by the Auto Coupler. In addition, when there is a possibility that back pressure is generated at the T port due to the System, install a check valve for preventing back flow having a cracking pressure of 0.04 MPa or less in the position with ★. *1 (Otherwise, oil leakage from the tip of the socket or malfunction of the pilot may occur.) 2 Lock opération procédure 1. In the connected condition, supply the pilot circuit with hydraulic pressure, and open the check valve of the plug. (ValveOoperation) 2. Supply each actuator circuit of the hydraulic jigs with hydraulic pressure. (ValveQope ration) 3. After finishing pressurization, shut off the hydraulic pressure supply to the pilot circuit. (ValveOoperation) 4. After shutting off the hydraulic pressure supply to ail the actuators, disconnect the Auto Coupler. (Valve ©opération) 3 The release opération can be performed only by supplying the pilot circuit with hydraulic pressure after connection. (Individual release can be performed by supplying each actuator with hydraulic pressure in advance after the connection.) Note *1. Select the device that can normally release at a pressure equal to or less than the cracking pressure. 12
