The solenoid valve type 195 must be supplied with power from

a voltage barrier certiﬁ ed for use in potentially explosive atmos-

pheres 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.

The voltage barrier for the equipment must have the following

maximum characteristics:

Uo = 28 V ; Io = 115 mA ; Po = 1,6W or

Uo = 32 V ; Io = 195 mA ; Po = 1,6W

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.

According to the zones and following the country legislation,

apply the certiﬁ cation procedure relative to the association of

IS products.

ASCO declines any responsibility for the use of products from

other suppliers and the possible modiﬁ cations of their charac-

teristics.

ELECTRICAL INSTALLATION

The solenoid valve must be installed under the responsibility

of the company operating the industrial site. The system as a

whole must conform to standard EN60079-14.

Before starting any work, turn off the electrical current to

power off the components.

All screw terminals must be tightened to the appropriate torque

prior to operation.

Install the cable so that there is no tension on the valve body.

When connecting the cables to the series 195 solenoid valves,

ﬁ rst place all the cables in the cable trays or wireways before

attaching them to the connectors.

The electrical connection is made by

• Detachable connector with an IP65 protection (when properly

mounted). Tighten each wire on the connector’s terminal to

the speciﬁ ed torque. The tightening torque for the cable gland

is 2,5 ±0,1 N.m to ensure tightness to IP65.

Spade plug connector, ISO 4400/EN 175301-803, form A

(cable entry dia. 6 to 8 mm).

The connector delivered with each product MUST be

mounted. Any other assembly/installation will invalidate

the approval. Do not mount or remove the connector while

the power is ON.

Operation: Before pressurising the system, ﬁ rst carry out an

electrical test. Apply power to the coil several times and listen

for the metallic «click» indicating the solenoid operator is work-

ing.

Personnel working with the components must be familiar with

electric controls, such as redundancies and feedback (electron-

ic controls), where applicable.

Use: The coils are designed for continuous operation and may

therefore become hot.

If the solenoid valve is easily accessible, provide for means of

protection to prevent accidental contact that may cause burns.

To avoid overheating, do not operate the solenoid valve in a

conﬁ ned space without sufﬁ cient ventilation.

CONNECTION

• Connect all ports that may come in contact with ﬂ uids. Mount

in accordance with the ISO 15218 (CNOMO size 30) mount-

ing pad pattern. Make sure to check that all seals are placed

on the mounting pad.

Pre-install the 2 CM4 x 35 screws alternately and evenly up to

a tightening torque of 0,3/0,5 Nm, and then tighten them to a

tightening torque of 1 Nm

±0,2

(E).

• Clean the conduits that will connect to the component.

• Be sure to observe the direction of ﬂ ow of the ﬂ uid.

• Use only the provided connection possibilities.

• Ensure that no foreign matter enters the circuit, in particular

when making the connection leakproof.

• The manual override, which is indicated by the symbol (

allows you to operate the valve without electrical power.

• Be sure to observe the allowed bend radius for tubing; do not

restrict the ports for ﬂ uid circulation.

• Tubes and connection elements must not exert any force,

torque, or strain on the product.

• Use appropriate tools and place assembly tools as close as

possible to the connection point.

• Be sure to observe the recommended torque when tightening

piping connections.

• Connections must be made to last.

CAUTION

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 for use in explosive atmospheres caused

by gases.

WARNING: Unauthorised personnel is not permitted to disas-

semble or remove the coil or connector assembly.

Take care not to damage the mating surfaces when disassembling

or re-assembling the connector/coil assembly/clip.

Wrong assembly will invalidate the approval.

OPERATION

To prevent the risk of personal injury or property damage, do

not touch the coil. The coil can become hot under normal op-

eration conditions. If the solenoid valve is easily accessible, the

installer must provide protection against accidental contact.

To prevent electrostatic hazard, clean coil surface with a damp

cloth only. Do not use solvents.

MAINTENANCE

CAUTION: Turn off electrical power before servicing.

Strictly follow all procedures recommended by European Direc-

tive 1999/92/EC and associated standards during maintenance.

There are no ATEX spare parts kits available.

The solenoid valve cannot be disassembled or adjusted.

Do not remove the coil from the pneumatic part of the solenoid

valve.

DISASSEMBLY/REASSEMBLY:

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

nel.

Unscrew and remove the connector. Remove the plug (6) and

the coil.

Reassemble in the reverse order of disassembly (make sure to

observe the tightening torques (A..D)).

The solenoid valve and the assembly consisting of the seal and

the connector must be completely re-assembled for IP65 pro-

tection to be certiﬁ ed.

Wrong assembly will invalidate the approval.

In case of replacement of parts by the user, the traceability

of the ﬁ nal product cannot be guaranteed by ASCO and

must be ensured by the user.
