Wiring
Wiring must comply with local codes and the National Electrical Code.
All solenoids supplied with lead wires are provided with a grounding
wire which is green or green with yellow stripes and a 1/2
conduit
connection. To facilitate wiring, the solenoid may be rotated 360
°
. For
explosionproof solenoid version, the conduit lead wires are factory
sealed for use in hazardous locations
.
Additional Wiring Instructions For Optional Features:
•
Open-Frame solenoid with 1/4
˝
spade terminals.
For solenoids supplied with screw terminal connections use #12-18 AWG
stranded copper wire rated at 90
°
C or greater. Torque terminal block
screws to 10±2 in-lbs [1,0±1,2 Nm]. A tapped hole is provided in the
solenoid for grounding, use a #10-32 machine screw. Torque grounding
screw to 15-20 in-lbs [1,7-2,3 Nm]. On solenoids with screw terminals,
the socket head screw holding the terminal block to the solenoid is the
grounding screw. Torque the screw to 15-20 in-lbs [1,7-2,3 Nm] with a
5/32
hex key wrench.
•
Junction Box
The junction box is used with spade or screw terminal solenoids only
and is provided with a grounding screw and a 1/2
conduit connection.
Connect #12-18 AWG standard copper wire only to the screw terminals.
Within the junction box use
eld wire that is rated 90
°
C or greater for
connections. For steam service use 105
°
C rated wire up to 50 psi or use
125
°
C rated wire above 50 psi. After electrical hookup, replace cover
gasket, cover, and screws. Tighten screws evenly in a crisscross manner.
•
DIN Plug Connector Kit No. K236034
1.
The open
-
frame solenoid is provided with DIN terminals to
accommodate the plug connector kit.
2.
Remove center screw from plug connector. Using a small
screwdriver, pry terminal block from connector cover.
3.
Use #12
-
18 AWG stranded copper wire rated at 90
°
C or greater
for connections. Strip wire leads back approximately 1/4
for
installation in socket terminals. The use of wire
-
end sleeves is also
recommended for these socket terminals. Maximum length of wire
-
end sleeves to be approximately 1/4
. Tinning of the ends of the
lead wires is not recommended.
4.
Thread wire through gland nut, gland gasket, washer and connector
cover.
NOTE:
Connector housing may be rotated in 90
°
increments from
position shown for alternate positioning of cable entry.
5. Check DIN connector terminal block for electrical markings. Then
make electrical hookup to terminal block according to markings
on it. Snap terminal block into connector cover and install center
screw.
6. Position connector gasket on solenoid and install plug connector.
Torque center screw to 5±1 in
-
lbs [0,6±1,1 Nm].
NOTE:
Alternating current (AC) and direct current (DC) solenoids
are built differently and cannot be converted from one to the other by
changing the coil.
Installation of Solenoid
Solenoids may be assembled as a complete unit. Tightening is
accomplished by means of a hex
ange at the base of the solenoid.
Installation of Panel Mounted Solenoid
(See Figure 3)
Disassemble solenoid following instruction under
Solenoid Replacement
then proceed.
3/4" Valve Bonnet Construction
1.
Install retainer (convex side to solenoid) in 1.312 diameter mounting
hole in customer panel.
2.
Position spring washer over plugnut/core tube sub
-
assembly.
3.
Install plugnut/core tube sub-assembly through retainer in customer
panel then replace solenoid, nameplate and red cap
.
15/16" Valve Bonnet Construction
1.
Install solenoid base sub-assembly through 0.69 diameter mounting
hole in customer panel.
2.
Position spring washer on opposite side of panel over solenoid base
sub
-
assembly then replace.
Solenoid Temperature
Standard solenoids are designed for continuous duty service. When
the solenoid is energized for a long period, the solenoid becomes hot
and can be touched by hand only for an instant. This is a safe operating
temperature.
MAINTENANCE
WARNING: To prevent the possibility of
death, serious injury or property damage, turnoff
electrical power, depressurize solenoid operator
and/or valve, and vent
fl
uid to a safe area before
servicing.
Cleaning
All solenoid operators and valves should be cleaned periodically.
The time between cleaning will vary depending on medium and service
conditions. In general, if the voltage to the solenoid is correct, sluggish
valve operation, excessive noise or leakage will indicate that cleaning
is required. Clean strainer or
lter when cleaning the valve.
Preventive Maintenance
•
Keep the medium
owing through the solenoid operator or valve as
free from dirt and foreign material as possible.
•
Periodic exercise of the valve should be considered if ambient or
uid conditions are such that corrosion, elastomer degradation,
uid contamination build up, or other conditions that could impede
solenoid valve shifting are possible. The actual frequency of exercise
necessary will depend on speci
c operating conditions. A successful
operating history is the best indication of a proper interval between
exercise cycles.
•
Depending on the medium and service conditions, periodic
inspection of internal valve parts for damage or excessive wear is
recommended. Thoroughly clean all parts. Replace any worn or
damaged parts.
Causes of Improper Operation
•
Faulty Control Circuit:
Check the electrical system by energizing
the solenoid. A metallic
click
signi
es that the solenoid is operating.
Absence of the
click
indicates loss of power supply. Check for
loose or blown fuses, open
-
circuited or grounded solenoid, broken
leadwires or splice connections.
•
Burned-Out Solenoid:
Check for open
-
circuited solenoid. Replace
if necessary. Check supply voltage; it must be the same as speci
ed
on nameplate/retainer and marked on the solenoid. Check ambient
temperature and check that the core is not jammed.
•
Low Voltage:
Check voltage across the solenoid leads. Voltage
must be at least 85% of rated voltage.
Solenoid Replacement
1.
On solenoids with lead wires disconnect conduit, coil leads, and
grounding wire.
NOTE:
Any optional parts attached to the old solenoid must be
reinstalled on the new solenoid.
2.
Disassemble solenoids with optional features as follows:
•
Spade or Screw Terminals
Remove terminal connections, grounding screw, grounding wire,
and terminal block (screw terminal type only).
NOTE:
For screw terminals, the socket head screw holding the
terminal block serves as a grounding screw.
•
Junction Box
Remove conduit and socket head screw (use 5/32
hex key
wrench) from center of junction box. Disconnect junction box
from solenoid.
•
DIN Plug Connector
Remove center screw from DIN plug connector. Disconnect DIN
plug connector from adapter. Remove socket head screw (use 5/32
hex key wrench), DIN terminal adapter, and gasket from solenoid.
3. Snap off red cap from top of solenoid base sub
-
assembly.
4. Push down on solenoid. Then using a suitable screwdriver, insert
blade in slot provided between solenoid and nameplate/retainer.
Pry up slightly and push to remove. Then remove solenoid from
solenoid base sub
-
assembly.
5. Reassemble using exploded views for parts identi
cation and
placement.
