The Series SN Solenoid Valves are designed to easily mount directly to
pneumatic valve actuators reducing the need for tubing, fittings or brackets,
thereby reducing assembly cost. The SN solenoid comes with BUNA O-rings and
offers a manual override as a standard feature. The 3/2 solenoids are designed for
spring return actuators and 5/2 solenoids are designed to be used with double
acting actuators. The SN series is available in a variety of voltage for any
application.

NSTALLATION
N
ote: Make sure that port o-rings are correctly placed inside o-ring groove.
1
. Affix solenoid valve to actuator and tighten screws.
2. Disconnect solenoid wire hood.
Note: Terminal designation (1) Positive (2) Neutral (3) Ground.
3. Energize solenoid valve several times and test for leaks and proper operation.
N
ote: Solenoid nut should be hand tight.
M
ANUAL OVERRIDE
T
he Proximity solenoid valve comes equipped with a manual override. A small push
button located between the valve body and the coil allows for the overriding of the
solenoid if necessary. The normal position for the button head is in a raised
position. Rotation of the button in the counter clockwise direction will manually
o
verride the solenoid and lock the solenoid in the disengaged position until the
s
crew head is returned to its original position.
Solenoid Classification
The Proximity solenoid valve is designed to IP65 standard.
NEMA 4, 4X: Watertight and dust tight - indoor and outdoor. Protects against
w
indblown dust, rain, splashing water and hose directed water. Also corrosion
r
esistant.
WIRING
Wire in accordance with the National Electrical Code and local regulations.
T
o aid in the wiring, the solenoid on the SN may be rotated 360°. For unwired
m
odels it is recommended to use 18 AWG copper wire rated at 90°C or greater.
Wiring the SN with DIN connector. See Figure 3.
1. Remove center screw and pull wiring assembly from the body.
2. Remove gasket and place small screw driver in slot to pry out the terminal block
f
rom the cover.
3
. Thread wire through the gland nut, gland gasket, washer and connector cover.
4
. Connect wires to proper terminals on the terminal block.
5
. Snap terminal block back into the cover. The connector cover may be rotated in
90° increments to position the cable entry as needed for the application. Reinstall
the center screw and screw back into the solenoid body.
M
AINTENANCE/REPAIR
U
pon final installation of the Series SN, no routine maintenance is required. The
S
eries SN is not field serviceable and should be returned if repair is needed. Field
repair should not be attempted and may void warranty.
