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
Protect the device from electrostatic discharge.
5 Function
When switching on the voltage, the solenoid is energised, and the valve is actu-
ated. A built-in current pulse generator permits operation on low-power electric
networks.

6.1 Mechanical system
Prevent the cable fitting from unscrewing when loosening the cap nut. Note the
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.
Open the cover of the clamping housing.
4.
Connect electrical cables to the terminals. Note polarity (tightening torque
2…3Nm).
5.
Close the cover of the clamping housing (tightening torque 0.6…0.7Nm).
6.
With external pilot air supply use port12.
7.
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 a cable with outside diameter 4…13mm for the installed M20 x 1.5
cable fitting.
2. Note polarity.
3.
To avoid ingress of water, tighten fitting and lock 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
The discharge of electrostatically charged parts can lead to ignitable sparks.
Prevent electrostatic charging by taking appropriate installation and cleaning
measures.
Include the device in the system’s potential equalisation. The surface coating of
the solenoid valves is electrically non-conductive.
Prevent processes that are charge-generating.
NOTICE
Escaping exhaust air can swirl up dust and create an explosive dust atmosphere.
NOTICE
Dimension the intrinsically safe circuit, taking account of the permissible electrical
limit values Technical data.è
NOTICE
For sheathed cables, observe the following:
Cut off the outer jacket of the cable and the sheathing at the same level.
Connect the sheathing at the other end to the potential equalisation.

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.
