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 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.
4.2 Intended use
The solenoid coil is intended to be used to actuate valves from Festo.
4.3 Identification X: special conditions
–
Only use specified solenoid valves.
–The range of application is dependent on the ambient temperature.
–
The device must be connected to a certified Ex ia IIC or Ex ib IIC intrinsically
safe circuit.
–
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.

Solenoid valve
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…6Nm).
3.
Open the cover of the clamping housing.
4.
Connect electrical cables to the terminals. Note polarity (tightening torque
2…3Nm).
5.
Close the cover of the clamping housing (tightening torque 0.6…0.7Nm).
6.
With external pilot air supply use port12.
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 7…13mm 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.
