INTENDED USE

The valve island AirLINE Type 8652 has been designed tocontrol pneumatic consumers in automation systems. Thevalve island must only be used for controlling suitable pneumatic consumers.
The valve island was designed for use in
Explosion group II, Category 3G Ex ec IIC Gc and Category
3D Ex tc IIIC Dc;
devices with the option PU17 are aditionally designed for use in
Cl I, ZN 2, AEx ec IIC Gc and Cl II ZN 22, AEx tc IIIC Dc and Cl
I, II, III, Div 2, Gr A, B, C, D, F, G
(see specifications on the adhesive label for approval).
▶ Install the device in a suitable control cabinet or housing.
▶ In the event of interference, ensure that the rated voltage isnot exceeded by more than 10% permanently or by morethan 40% temporarily (transients).
▶ Do not use the device outdoors.
▶ Prerequisites for safe and trouble-free operation are correcttransportation, correct storage, installation, start-up, operation and maintenance.
▶ To use the device, observe the permitted data, operating conditions and application conditions. These specifications canbe found in the contract documents, the operating instructions and on the type label.
▶ Use the device only in conjunction with third-party devices andcomponents recommended or approved by Bürkert.
▶ Use the device only when it is in perfect condition.
▶ Use the device only as intended. Non-intended use of thedevice may be dangerous to people, nearby equipment andthe environment.

For systems in the potentially explosive atmosphere, which areinstalled in a housing (degree of protection at least IP54 for Category 3G/Gc or IP64 for Category 3D/Dc), ensure the following:▶ The control cabinet must be approved for use in the potentially explosive atmosphere.
▶ The control cabinet must be dimensioned in such a way thatthe resulting heat loss can be discharged to the outside using
suitable means.
▶ The internal temperature of the control cabinet must notexceed the maximum permitted ambient temperature for thedevice.

Safety instructions in the potentially explosive
atmosphere

3SAFETY INSTRUCTIONS IN
THE POTENTIALLY EXPLOSIVE
ATMOSPHERE

To prevent a risk of explosion, follow not only the safety instructions in the operating instructions, but also the safety instructionsin these additional instructions.

Danger due to electric voltage.
▶ Before working on the device or system, switch off the powersupply. Secure against reactivation.
▶ In the potentially explosive atmosphere, only plug or unplug
the connection terminals in a de-energised state for thefunctions– 24 V power supply
– SIA
– EVS
– Digital inputs(for exception see chapter “4”).
▶ In the potentially explosive atmosphere, only plug or unplug
fixed cable connections that can be inserted into the connection terminals in a de-energised state. De-energise all circuits
connected to the connection terminals.
▶ Usage of the hot swap function is prohibited in the potentiallyexplosive atmosphere (for exception see chapter “4.1”).
▶ Observe the applicable accident prevention and safety regulations for electrical devices.

englishRisk of explosion due to electrostatic charge.
If there is a sudden discharge of electrostatically charged
devices or persons, there is a risk of explosion in the potentiallyexplosive atmosphere.
▶ Use suitable measures to ensure that electrostatic charges
cannot occur in the potentially explosive atmosphere.
▶ Clean the device surface by gently wiping it with a damp or
anti-static cloth only.
Risk of injury due to improper installation, operation ormaintenance.
▶ Only qualified technicians may perform installation work,operating procedures or maintenance work.
▶ Perform installation work and maintenance work using suitable tools only.
General hazardous situations.
To prevent injuries, observe the following:▶ Operate the device only when it is in perfect condition and inaccordance with the operating instructions.
▶ Observe applicable safety regulations (also national safetyregulations) as well as the general rules of technology during
setup and operation.
▶ Do not repair the device, but replace it with an equivalentdevice. Repairs may be carried out by the manufacturer only.
▶ Do not place the device under mechanical stress (e.g. byplacing objects on it or standing on it).
▶ Do not subject the device to mechanical and/or thermal
stresses/influences which exceed the limits described in theoperating instructions.

Special conditions for general use

4

SPECIAL CONDITIONS FORGENERAL USE▶ For type of protection “ec” (gas):
Install the device in a housing which meets the applicablerequirements of the type of protection “ec” according to EN/
IEC 60079-0 and EN/IEC 60079-7 and has a degree of protection of at least IP54.
▶ For type of protection “tc” (dust):
Install the device in a housing which meets the applicablerequirements of the type of protection “tc” according to EN/
IEC 60079-0 and EN/IEC 60079-31 and has a degree of protection of at least IP6X.
▶ Use the device only in an area which has minimum pollution
degree 2, as defined in IEC 60664-1.
▶ Ensure that the transient protection has been set to a value
which does not exceed 140% of the rated peak voltage valueon the supply connections of the device.
▶ In the potentially explosive atmosphere, only plug or unplug
the connection terminals in a de-energised state for thefunctions– 24 V power supply
– SIA
– EVS
– Digital inputs
If it can be verified and ensured with suitable testing materials
that there will not be a potentially explosive atmosphere overa certain period of time, the plugging/unplugging of connection terminals is always functionally possible during thistime.

▶ In the potentially explosive atmosphere, only plug or unplug
fixed cable connections that can be inserted into the connection terminals in a de-energised state. De-energise all circuits
connected to the connection terminals.

4.1

Special conditions for using the hotswap function

Usage of the hot swap function is prohibited in the potentiallyexplosive atmosphere.
If it can be verified and ensured with suitable testing materials
that there will not be a potentially explosive atmosphere over acertain period of time, the removal or addition of a valve is permitted during this time.
Only specially trained personnel may perform the hot swap
function.

Explosion protection approval

EXPLOSION PROTECTION
APPROVAL

The explosion protection approval is only valid if you use themodules and components approved by Bürkert as described inthese operating instructions.
The devices may be used only in combination with the valve types
approved by Bürkert, otherwise the explosion protection approval
will expire.
In the event of unauthorised changes to the system, modules orcomponents, the explosion protection approval will also expire.

Additional adhesive label

If device structures have fewer than 48 valve functions, lesspower is converted, so that the considered and measured
maximum temperatures are the same or lower.

If the existing safety information on the adhesive label for thepotentially explosive atmosphere (“Fig. 2” or “Fig. 3”) is not
visible or only partially visible due to the installation position of
the valve island in the control cabinet:

6.3→ Attach an additional adhesive label to the valve island so that
it is clearly visible.

At a maximum ambient temperature of +55 °C inside the control
cabinet, the limits of temperature class T4 are not exceeded.

Service temperature

If variant AirLine Quick is used in a control cabinet (refer to operating instructions Type 8652), the maximum service temperatureon the outside does not exceed +80 °C at any point.
The operating temperature and the necessity to mark an
operating temperature class shall be investigated in the end
product.
