taining the solenoid valve.

DESCRIPTION

Essential Health and Safety Requirements: Solenoid

operators types

LI / WSLI

are designed in accordance with

IEC and EN Standards references: 60079-0, 60079-11 and

60079-31.

INSTALLATION

Our components are intended to be used only within the

technical characteristics speciﬁ ed on the nameplate. Sole-

noid operators Types

LI

/

WSLI

are designed to be installed

in potentially explosive atmospheres caused by gases of

groups IIA, IIB and IIC, vapours or mists of category 1G (LI

/ WSLI) and dusts (category 2D). The surface temperature

classiﬁ cation is T6-T85°C and depends on the power rating

and ambient temperature stated on the coil.

Special conditions for safe use:

- The apparatus may only be connected to certiﬁ ed intrinsically

safe equipment. This combination must be compatible as

regards the intrinsic safety rules (see electrical parameters

under «Electrical Characteristics»).

-

(1)

Equipment type LI must be protected against

mechanical shock and friction when used in zone 0.

-

(2)

If the WSLI apparatus is used with an aluminium

solenoid operator then the enclosure has to be

protected from any mechanical or friction impacts

when it is used in zone 0.

- Ambient operating temperature: - 40°C to + 60°C

The solenoid operators type

LI or WSLI

must be supplied with

power from a voltage barrier certiﬁ ed for use in potentially

explosive atmospheres of groups IIC, IIB or IIA and having

an output circuit that is rated intrinsically safe. The valve-and-

barrier combination must be compatible in terms of intrinsic

safety.

Since the two parameters Ci and Li of the equipment are both

equal to zero, the maximum output characteristics Co and

Lo of the voltage barrier must exceed the effective values of

C and L of the connecting cable used.

Selecting the barrier and making the interconnections are at

the user’s responsibility.

COMPATIBLE BARRIERS AND INTERFACES

These pilot valves are compatible with the barriers given in

the table. These barriers and interfaces allow to feed the

intrinsically safe solenoid valves located in explosive areas.

This equipment must be ordered from its respective manu-

facturers specifying that they are intended to feed intrinsically

safe solenoid valves intrinsically safe: LI / WSLI

According to the zones and following the country legislation,

apply the certiﬁ cation procedure relative to the association

of IS products.

We decline all responsibility for the use of products from

other suppliers and the possible modiﬁ cations of their char-

acteristics.

ELECTRICAL INSTALLATION

Wiring must comply with local and national regulations

concerning equipment for use in explosive atmospheres.

To prevent overloading and causing an ignition source, a

fuse or circuit breaker of maximum 100 mA must be used.

NOTE: Alternating current (AC) and direct current (DC) so-

lenoids are built differently. To convert from one to the other,

it is necessary to change the complete solenoid including

the core and solenoid base sub-assembly, not just the coil.

Contact ASCO.

C

Standard cable gland accepts cables

with overall O.D. from 6 to 12 mm. IP66/IP67: Tighten

the cable gland at a torque of min. 8 Nm (torque C).

Min. temperature -35°C.

E

Caution (metal cable gland): In order to obtain

IP66/IP67, it is necessary to put graphite grease on the

1/2” NPT threads according to Standard IEC-EN 60079-14

(torque E = 7 N.m).

Min. temperature -40°C.

Position the solenoid operator before making the electrical

connection. To make the wiring connections to the coil ter-

minals, remove the cover from the solenoid operator. Re-

move the outer insulation from the cable by approx. 30 mm

and strip 8 mm off the wires. Introduce the wires into the

cable-gland and connect them to the coil terminals. Con-

nect the cable ground wire to the ground terminal. Leave

enough slack in the wires between the cable entry and the

coil to avoid excessive strain on the wires. Assemble the

cable gland and tighten the elastomer compression seal so

that it ﬁ ts tightly around the cable.

Close the housing and tighten the 4 cover screws to

the speciﬁ ed torque. The solenoid operator’s housing is

equipped with an external terminal for an earth wire.

CAUTION

The power supply must be within the range speciﬁ ed on the

nameplate. Failure to stay within the electrical range of the

coil rating will result in damage to or premature failure of the

coil. This will also invalidate its approval.

WARNING: Unauthorised personnel is not permitted to re-

move the cover from the solenoid operator.

Take care not to damage the mating and sealing surfaces

when disassembling or reassembling the cover of the sole-

noid operator.

Wrong assembly will invalidate the approval.

SERVICE

To prevent the risk of personal injury or property damage,

do not touch the solenoid operator. It can become hot under

normal operation conditions. If the solenoid valve is easily

accessible, the installer must provide protection against ac-

cidental contact.

MAINTENANCE

For servicing, refer to the solenoid valve’s Installation and

Maintenance Instructions.

Spare parts kits are available (contact us). If problems arise

during installation or maintenance or in case of doubt, please

contact us or one of our authorised representatives.

CAUTION: Prior to any maintenance work, power off and

depressurise the valve and vent ﬂ uid to a safe area.

DISASSEMBLY AND RE-ASSEMBLY OF SOLENOID

OPERATOR ON VALVE:

This operation must be carried out by suitably qualiﬁ ed per-

sonnel.

Unscrew the 4 screws and remove the cover.

Disconnect the electrical wires, remove the coil and its yoke.

Proceed in reverse order to re-install.

The solenoid operator must be fully reassembled as the hous-

ing and internal parts close the magnetic circuit.

Replacement of screw no. 1: Only use screws with 700 N/mm

2

minimum tensile strength.

In case of replacement of parts by the user, the trace-

ability of the ﬁ nal product cannot be guaranteed by us

and must be ensured by the user.

Wrong assembly will invalidate the approval.
