As for “K1”, “K2”, “Q1” and “N1”, use the vacuum release valve when a workpiece is detached. Concerning “J1”, “J2”, “Q2” and “N2”, devise the circuit for the vacuum release additionally when a workpiece is detached. Note 1) In cases when “K2” or “J2” (supply valve normally open) is selected for the solenoid valve combination, when vacuum is stopped for long periods of time (10 minutes or more), do not continue to energize the supply valve, and shut off the air supply. e Pilot valve (Refer to Table (1).)
