4 Safety
4.1
General 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.
–
Do not commission the solenoid coil until after mounting.
–Fit a suitable valve with a suitable armature guide tube

catalogue.
–Work on the product may only be carried out by qualified personnel who can
evaluate the work and detect dangers.
4.2 Intended use
The solenoid coil is intended to be used to actuate valves from Festo.
4.3 Identification X: special conditions
VACC-S13-18-K4-1UF-...ME
–Solenoid coil includes an internal protective device.
–
Observe the permitted mounting position of the solenoid coil
è
10 Technical
data.
–
Protect the device from electrostatic discharge.
VACC-S13-18-K4-...U-...ME
–
Only operate solenoid coils with fuses connected in series
è
10 Technical data.
–The breaking capacity of the fuse insert must be equal to or greater than 250A.
–
Observe the permitted mounting position of the solenoid coil
è
10 Technical
data.
–Protect the device from electrostatic discharge.

Function
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.

Mechanical
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.
6.2 Electrical
1. Use only an unsheathed cable with an outside diameter of 7…13mm for the
installed cable fitting M20 x 1.5.
2. Note polarity.
3.
To avoid ingress of water, tighten fitting and locking ring with an open-ended
spanner until the sealing force is sufficient.
4.
Use strain relief.

Commissioning
WARNING
Risk of injury from touching hot surfaces.
Contact with housing of the solenoid coil can cause burn injuries.
• Do not touch the housing.
WARNING
Electrostatic discharge may generate combustible sparks.
The product may become electrostatically charged. The surface coating of the
solenoid valve is not electrically conductive.
•
Prevent electrostatic charging of the product with appropriate installation and
cleaning measures.
• Include the solenoid valve and solenoid coil in the system equipotential
bonding.
• Prevent processes that could generate charges.
•
Do not operate the device in areas subjected to accelerated particle flows.
NOTICE
Escaping exhaust air can swirl up dust and create an explosive dust atmosphere.
Bei VACC-S13-18-K4-…U-…ME:
Operate solenoid coil only with fuses connected in series.
8
Maintenance and care
WARNING
Risk of injury due to defective solenoid coil.
Cracks in the housing and sealing compound impair the explosion prevention and
protection.
•
Check solenoid coil regularly.
• Replace faulty solenoid coil.
WARNING
Electrostatic discharge may generate combustible sparks.
The product may become electrostatically charged.
If used in group IIC:
•
Only clean the device with a damp cloth.
–Changes or repairs to the solenoid coil are not permitted.
–
The device is maintenance-free.
9 Disassembly
When loosening the cap nut, prevent the cable connector from working loose.
WARNING
If the terminal housing cover is opened, explosive atmosphere may penetrate
the terminal housing and be ignited due to electrically generate sparks.
Before opening the terminal housing cover inside the potentially explosive area:
•
Switch off the power supply.
1.
Switch off the power supply.
2.
Release terminal housing cover.
3. Disconnect electrical cables from terminals.
4. Close terminal housing cover.
5. Loosen the retaining nut. Remove solenoid coil.
