in connection with third-party devices or components recommended or approved by Bürkert. Observe the instructions in
this operating manual, as well as the conditions of use and
permissible data specified in the chapter “5.1. Operating conditions of the devices”.
The proper and safe function of the system depends on
proper transport, storage and installation, and on careful
operation and maintenance.
• The device serves exclusively as a piezoelectric actuator for the
media stated in the data sheet and for use in Explosion Group II,
Category 2 G and Temperature Class T6 (see data on the
approval plate).
• The type of protection used is inherent safety EEx i. Connection
is made by rectangular connectors, circular connectors or via 2
impressed wires.
• The device must be installed in a housing with a protection type
of at least IP 20 to EN 60529.
• The device may be used in a potentially explosive atmosphere
only in the manner approved by the Physikalisch-Technische
Bundesanstalt, i.e. the values specified in the approval or the
electrical wiring must be observed.
• Any other use or use exceeding the specific scope is considered to be non-intended use. Bürkert will not be liable for any
damage resulting therefrom. The risk will be borne by the user.
2.1. Limitations
If exporting the system/device, observe any existing restrictions.
EX approval
The EX approval is only valid if the modules and components authorized
by Bürkert are used as described in these operating instructions.
Type 6106 may be used only in combination with the additional components released by Bürkert, otherwise the EX approval will be voided!
If any unauthorized changes are made to the device, modules or components, the EX approval will also be voided.
2.2. Licences
The EC type-examination certificate PTB 01 ATEX 2194 X was
issued by the
PTB (Physikalisch Technische Bundesanstalt)
Bundesallee 100
38116 Braunschweig
which also audits production (CE 102).
The EC type-examination certificate can be found on the Internet at:
www.burkert.com

General safety instructions
3. GENERAL SAFETY INSTRUCTIONS
DANGER!
Risk of explosion if the device is opened!
• The device is a sealed system. It must not be opened.
Hazard due to high pressure!
Interference with the system will result in an acute risk of injury.
• Switch off the pressure before loosening pipes and modules!
Hazard due to electrical voltage!
Interference with the system will result in an acute risk of injury.
• Before starting work, be sure to switch off the supply voltage
and secure it to prevent restarting!
• Observe all applicable accident prevention and safety regulations for electrical equipment!
Danger of explosion caused by electrostatic charge!
If there is a sudden discharge from electrostatically charged
devices or persons, there is a danger of explosion in the EX area.
• Using suitable measures, ensure that no electrostatic charges
can occur in the EX area.
• Clean the device surface by gently wiping it with a damp or antistatic cloth only.
WARNING!
General Hazardous Situations.
• Do not supply the medium connectors of the system with
aggressive or flammable mediums.
• Do not supply the medium connectors with any liquids.
• Do not put any loads on the housing (e.g. by placing objects on
it or standing on it).
• Do not make any external modifications to the device housings.
Do not paint the housing parts or screws.
To prevent injuries:
• Ensure that the system cannot be activated unintentionally.
• Installation and maintenance work may be carried out only by
authorized technicians with the appropriate tools.
• After an interruption in the power supply or pneumatic supply,
ensure that the process is restarted in a defined or controlled
manner.
• The device may be operated only when in perfect condition and
in consideration of the operating instructions.
• The general rules of technology must be observed for application
planning and operation of the device.
Failure to observe this operating manual and its operating
instructions as well as unauthorized tampering with the device
release us from any liability and also invalidate the warranty
covering the devices and accessories!
