BURKERT 8652 AirLINE valve island has been especially developed for process automation requirements. New diagnostic functions can be visualised on the LC display, both in clear text as well as symbols. This makes it easy to relate to the shown messages and helps to save time during start-up and maintenance. Furthermore, the diagnostic message is also available at the controller, enabling a fast overview of the plant status.

The hardware is optimised for installation at the bottom of the control cabinet. Installation on a standard rail is also possible. Key pneumatic functions ensure increased process reliability. For instance, check valves in the exhaust air ducts make sure there is no unplanned actuation due to pressure peaks. The system supports PROFINET S2 (system redundancy) for higher plant availability and allows for safety-related shut-off of valves.

AirLINE Quick

AirLINE Quick considerably reduces the use of components in the control cabinet. With the AirLINE Quick Adapter, the valve terminal is adapted directly to the control cabinet floor or control cabinet wall.

Advantages:

• Reduced space requirement in the control cabinet
• Makes it possible to use more compact control cabinets
• Reduced installation effort due to hose connections directly at the bottom of the control cabinet

Product Installation

Hot Swap Function

To use the Hot Swap function, always observe a minimum distance to the front edge of the control cabinet when installing the valve island inside the control cabinet.

Explosion Protection (EX) Safety Instructions

Danger due to voltage and electrostatic charge

• Before working on the device or system, disconnect the power supply and secure against reactivation.
• In an existing explosive atmosphere, the connection terminals for 24 V power supply, SIA, EVS, and digital inputs may only be plugged in or unplugged when the power is switched off.
• The use of the Hot Swap function is prohibited in an existing explosive atmosphere unless it can be proven by suitable test equipment that no explosive atmosphere is present for a certain period.
• Take suitable measures to ensure that no electrostatic charge can build up in the potentially explosive area. Clean the device surface by gently wiping it with a damp or antistatic cloth only.
