Light/Surge Voltage Suppressor
In the case of voltage suppressor, surge volt-
age absorption element is attached to termi-
nal block on body area.

How to Exchange
Solenoid valve
•Loosen set screw and take solenoid valve out
vertically, otherwise it may cause damage to
the solenoid valve. Never remove a valve at
an angle.
•When mounting solenoid valve onto the base,
plug pin ass'y (base-side) into receptacle
ass'y (body-side) vertically.
Pilot valve
•When changing the rated voltage, electrical
entry, etc., pilot valve ass'y can be exchanged
easily since this is plug-in style. Then, when
changing the rated voltage with light/surge
voltage suppressor, change of light/surge volt-
age suppressor substrate is also needed. So,
order together with pilot valve assembly.
Light and surge voltage suppressor substrate part No.
