4.1

Safety instructions

–

The solenoid coils can be used in combination with the specified solenoid

valves in zones 1 and 2 for explosive gas atmospheres and in zones 21 and 22

for explosive dust atmospheres.

–Operate the solenoid valve with compressed air only.

–

The device is not intended for use with other fluids.

–Always draw in the operating medium outside the potentially explosive area.

–

Installation and commissioning only by qualified electricians in accordance with

the operating manual.

–The range of application is dependent on the ambient temperature.

–

Comply with all applicable national and international instructions.

–Use the device in its original status without any unauthorised modifications.

The certification is no longer valid if the device is modified in any way by

anyone other than the manufacturer.

4.2Intended use

The solenoid coil is intended to be used to actuate valves from Festo.

4.3Identification X: special conditions

VACC-S18-…-K4-1UF-…ME

–For use in explosive dust atmospheres the cable must be installed to elimi-

nate the generation of electrostatic charges caused by processes, e.g. flowing

media.

VACC-S18-…-K4-…U-…ME, VACC-S18-120-K4-7-…ME and

VACC-S18-120-K4-27-…ME

–

Only operate the solenoid coils with upstream fuses

–

For use in explosive dust atmospheres the cable must be installed to elimi-

nate the generation of electrostatic charges caused by processes, e.g. flowing

media.

5Function

When switching on the voltage, the solenoid is energised, and the valve is actu-

ated.

–In variants for DC/AC an integrated bridge rectifier limits the switch-off over-

voltage.

–An integrated TVS diode limits the switch-off overvoltage in variants for DC.

6

Transport and storage

–

Observe the following storage conditions: short storage times in cool, dry,

shaded and corrosion-resistant locations.

7.1Mechanical

1.

Push the solenoid coil and retaining washer over the armature guide tube.

2.Tighten retaining nut. Twisting the solenoid coil is no longer possible (tight-

ening torque 15 … 20 Nm).

3.Release terminal housing cover.

4.Connect electrical cables to the terminals.

5.

Connect the solenoid coil to the equipotential bonding by the inner or outer

protective earth connection (tightening torque 2 … 3 Nm).

6.

Close terminal housing cover (tightening torque 1.5 Nm).

NOTICE

The surface coating of the solenoid valves is electrically non-conductive.

•Include the device in the system equipotential bonding.

7.2Pneumatic

1.Mount connecting cables and fittings properly. Before commissioning, remove

residues, such as chips, rust and water.

2.Switch off pressure to the compressed air lines.

3.

Use only fittings with cylindrical threaded lugs and sealing rings or cutting

rings.

4.

Do not use PTFE or hemp fibres on the threads.

5.Insert all sealing rings supplied with the NAMUR mounting kit between sole-

noid valve and drive or mounting plate.

6.If port 1 with control signal 2 bar, then supply auxiliary energy 2 bar to<>

port 12.
