4Safety

4.1General safety instructions

–

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

valves in zones 1 and 2 for potentially explosive gas atmospheres and in zones

21 and 22 for potentially explosive dust atmospheres.

–Operate the solenoid valve with compressed air only.

–

The device is not intended for use with other fluids.

–Observe the specifications on the product labelling.

–

Do not commission the solenoid coil until after assembly.

–Observe the operating conditions.

–Extraction of the operating medium outside the potentially explosive area.

–

Installation and commissioning should only be carried out by qualified elec-

trical specialists.

4.2Intended use

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

4.3Identification X: special conditions

VACC-S13-18-K4-1UF-...ME

VACC-S13-18-K4-...U-...ME

–

Only operate solenoid coils with fuses connected in series

è

10 Technical data.

–The interruption rating of the fuses must be equal to or greater than 1500 A.

–

Only use specified solenoid valves.

data.

–Protect the device from electrostatic discharge.

5Function

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

ated. A built-in bridge rectifier limits the switch-off overvoltage.

6.1Mechanical

When loosening the cap nut, prevent the cable connector from working loose.

Note tightening torque: cable fitting 2.3 Nm; cap nut 1.5 Nm.

1.Push the solenoid coil and spring washer over the armature guide tube.

–Sealing compound points to the solenoid valve.

2.Tighten vent screw. Twisting the solenoid coil is no longer possible (tightening

torque 4 … 6 Nm).

3.

Release terminal housing cover.

4.Connect electrical cables to the terminals. Note polarity (tightening torque

2 … 3 Nm).

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

protective earth connection.

6.Close terminal housing cover (tightening torque 0.6 … 0.7 Nm).

7.With external pilot air supply, use connection 12.

8.Seal unused openings with blanking plugs or slot covers.

NOTICE

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

•Include the device in the system equipotential bonding.

6.2Pneumatic

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.

7.

Do not use anti-friction coating or lubricant.
