-SERVICE NOTICE-

ASCO

solenoid valves with design change letter "G" in the catalog

number (example: 8210G 1) have an epoxy encapsulated ASCO

Red

Hat II. solenoid. This solenoid replaces some of the solenoids with metal
enclosures and open-frame constructions. Follow these installation and
maintenance instructions if your valve or operator uses this solenoid.

DESCRIPTION

Catalog numbers 8016G1 and 8016G2 are epoxy encapsulated pull-type
solenoids. The green solenoid with lead wires and 1/2 " conduit connec-
tion is designed to meet Enclosure Type 1 -General Purpose,Type 2-
Dripproof,Types 3 and 3S-Raintight, and Types 4 and 4X-Watertight. The
black solenoid on catalog numbers prefixed "EF" is designed to meet
Enclosure Types 3 and 3S-Raintight, Types 4 and 4X-Watertight, Types 6
and 6P-Submersible, type 7 (A, B, C, & D) Explosionproof Class 1,
Division 1, Groups A, B, C, & D and Type 9 (E, F, & G)-Dust-lgnitionproof
Class 11, Division 1, Groups E, F, & G. The Class 11, Groups F & G Dust
Locations designation is not applicable for solenoids or solenoid valves
used for steam service or when a class "H" solenoid is used. See
Temperature Limitations section for solenoid identification and name-
plate/retainer for service. When installed just as a solenoid and not
attached to an ASCO valve, the core has a 0.250-28 UNF-2B tapped hole,
0.38 minimum full thread.

Series 8016G solenoids are available in:

• Open-Frame Construction

The green solenoid may be supplied with 1/4 spade, screw, or
DIN terminals (Refer to Figure 4).

• Panel Mounted Construction

These solenoids are specifically designed to be panel mounted by the
customer through a panel having a .062 to .093 maximum wall thickness.
(Refer to Figure 3 and section on Installation of Panel Mounted Solenoid).

Optional Features For Type 1—General Purpose
Construction Only

• Junction

Box

This junction box construction meets Enclosure Types 2,3,3S,4, and
4X. Only solenoids with 1/4" spade or screw terminals may have a
junction box. The junction box provides a 1/2 conduit connection,
grounding and spade or screw terminal Connections within the junction
box (See Figure 5).

• DIN Plug Connector Kit No. K236 - 034

Use this kit only for solenoids with DIN terminals. The DIN plug connector kit
provides a two pole with grounding contact DIN Type 43650 construction
(See Figure 6).

OPERATION

When the solenoid is energized, the core is drawn into the solenoid base sub-
assembly.

IMPORTANT:

When the solenoid is de-energized, the initial

return force for the core, Whether developed by spring, pressure, or
weight, must exert a minimum force to overcome residual magnetism cre-
ated by the solenoid. Minimum return force for AC construction is 11 ounces,
and 4 ounces for DC construction.

INSTALLATION

Check nameplate for correct catalog number, service, and wattage. Check front
of solenoid for voltage and frequency.

WARNING: To prevent the possibility of electrical shock from
the accessibility of live parts, install the open-frame solenoid
in an enclosure.

FOR BLACK ENCLOSURE TYPES 7 AND 9 ONLY

CAUTION:

To prevent fire or explosion, do not install solenoid and/or valve

where ignition temperature is less than 165˚ C. On valves used for steam
service or when a class "H" solenoid is used, do not install in hazardous atmos-
phere where ignition temperature is less than 180˚ C. See nameplate/retainer for service.

NOTE:

These solenoids have an internal non-resetable thermal fuse to limit

solenoid temperature in the event that extraordinary conditions occur which could
cause excessive temperatures. These conditions include high input voltage, a
jammed core, excessive ambient temperature or shorted solenoid, etc.
This unique feature is a standard feature is a standard feature only in
solenoids with black explosionproof/dust-ignitionproof enclosures
(types 7&9).

IMPORTANT: To protect the solenoid valve or operator, install a strain-
er or filter, suitable for the service involved in the inlet side as close to the
valve or operator as possible. Clean periodically depending on service con-
dition & See ASCO Series 8600, 8601, and 8602 for strainers.

Temperature Limitations

For maximum valve ambient temperatures, refer to chart. The temperature limita-
tions listed, only indicate maximum application temperatures for field wiring rated
at 90°C. Check catalog number prefix and watt rating on nameplate to deter-
mine maximum ambient temperature. See valve installation and maintenance
instructions for maximum fluid temperature.

NOTE:

For steam service, refer to

Wiring section, Junction Box for temperature rating of supply wires.

Minimum ambient temperature -40° F (-40° C). Positioning

Positioning

This solenoid is designed to perform properly when mounted in any position.
However, for optimum life and performance, the solenoid should be mounted ver-
tically and upright to reduce the possibility of foreign matter accumulating in the
solenoid base sub-assembly area.

Wiring

Wiring must comply with local codes and the National Electrical Code. All sole-
noids 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 the watertight and explosionproof solenoid,
electrical fittings must be approved for use in the approved 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 strand-
ed 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 #Y10-32 machine screw. Torque grounding screw to 15 -20
