Refer to front matter 53 for Safety Instructions and pages 3 to 8 for 3/4/5 Port Solenoid Valve Precautions. Appropriate output sequences are affected according to the signal received from the mechanical valve. It is equivalent to the auxiliary relay of an electrical system. Precautions Environment Operate the valve in an area in which the vibration does not exceed 5 G. Vibrations could cause the valve to malfunction.
