Basic Safety Instructions
3. BASIC SAFETY INSTRUCTIONS
These safety instructions do not make allowance for any:
• Contingencies and events which may arise during the installation, operation and maintenance of the devices.
• Local safety regulations – the operator is responsible for observing these regulations, also with reference to the
installation personnel.
Danger – high pressure!
• Before dismounting pneumatic lines and valves, turn off the pressure and vent the lines.
Risk of electric shock!
• Before reaching into the device or the equipment, switch off the power supply and secure to prevent
reactivation!
• Observe applicable accident prevention and safety regulations for electrical equipment!
Risk of burns/risk of fire if used continuously through hot device surface!
• Keep the device away from highly flammable substances and media and do not touch with bare hands.
General hazardous situations.
To prevent injury, ensure:
• That the system cannot be activated unintentionally.
• Installation and repair work may be carried out by authorized technicians only and 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.
• Note that pipes and valves must not become detached in systems which are under pressure.
• Before reaching into the system, always switch off the power supply!
• Design the pressure supply with the largest possible volume to prevent a pressure drop when the system is
switched on.
• The general rules of technology apply to application planning and operation of the device.
NOTE!
Operate system with direct current only!
To prevent damage to the system, use only direct current for the system power supply.
Prevent a pressure drop!
To prevent a pressure drop, design the system pressure supply with the largest possible volume.
Electrostatic sensitive components / assemblies!
The device contains electronic components which react sensitively to electrostatic discharge (ESD). Contact
with electrostatically charged persons or objects is hazardous to these components. In the worst case scenario,
they will be destroyed immediately or will fail after start-up.
• Observe the requirements in accordance with EN 61340-5-1 and 5-2 to minimize or avoid the possibility of
damage caused by sudden electrostatic discharge!
• Also, ensure that you do not touch electronic components when the power supply voltage is present!

System Description
5. SYSTEM DESCRIPTION
5.1. Application area
The AirLINE system is designed for decentralized use in industrial environments. Electronics and fluidics can be
combined particularly easily and efficiently thanks to the modular design.
DANGER!
Danger of explosion!
If systems in the explosion-protected area are installed in a control cabinet, the following requirements must be met:
• The control cabinet must be authorized for use in the explosion-protected area.
• The control cabinet must be large enough to allow the resulting lost heat to be dissipated in a suitable manner to the outside.
• The internal temperature of the control cabinet must not exceed the max. permitted ambient temperature for
the device.
Risk of electric shock!
• Before reaching into the device or the equipment, switch off the power supply and secure to prevent
reactivation!
• Observe applicable accident prevention and safety regulations for electrical equipment!

System Description
The Type 8644 Bürkert AirLINE is an electrical and pneumatic automation system which was developed for use in
the control cabinet or switch box. In a continuous system all electronic and pneumatic components are standardized,
enabling pneumatic, electric and electronic modules with various functions to be combined very easily with each
other by the observation of simple rules. All components are connected by a locking mechanism. At the same time
the required electrical connections are also established. For example, valves and power outputs can be combined
with one field bus connection only. A large number of electrical modules (terminals) can be combined very easily
with the valves mounted on special pneumatic modules (valve discs).
In its minimum configuration the system consists of the interface module IM151, a power module and the valve block.
Electronic modules of the ET200S system can be installed before and after the valve block. A power module must
always be provided after the interface module and without fail before the valve block. If the configuration requires
electronic modules after the valve block, a power module must be placed without fail after the valve block or before
the electronic modules, as the power supply voltage must be fed again. The maximum configuration of the decentralized peripheral device comprises 64 nodes (including interface module, power modules, peripheral modules and
pneumatic base modules).
In its maximum configuration the valve block comprises 64x 11 mm (ME02) add-on dimension valves and 32x 16.5 mm
(ME03) add-on dimension valves which function monostably. If the configuration of the valve block also provides for
valves of Type 0461, a maximum of 24x 16.5 mm add-on dimension valves is authorized.
The ET200S supports the removal and insertion of modules during operation (RUN operating state). The function
module can be removed during operation the same as the electronic modules of the ET200S. However, the operating pressure must be switched off beforehand! To do this, it is essential to observe Chapter “7. Structure and
function of the modules”.
