Burkert Type 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, though installation on a standard rail is also possible. Key pneumatic functions ensure increased process reliability, such as check valves in the exhaust air ducts that prevent unplanned actuation due to pressure peaks.

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

Installation Notes

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.

ATEX/IECEx Safety Instructions

• Danger from voltage: Before working on the device or system, disconnect the power supply and prevent it from being switched on again.
• Hot Swap restriction: The use of the Hot Swap function is prohibited in a currently explosive atmosphere. If it can be proven and ensured with suitable test equipment that there is no explosive atmosphere for a certain period of time, it is permissible to remove/insert valves using Hot Swap during this time.
• Electrostatic charge: Take appropriate measures to ensure that no electrostatic charge can occur in the potentially explosive area. Clean the device surface only by wiping it gently with a damp or antistatic cloth.
