BURKERT 20128727 Type 8652 AirLINE valve island has been especially developed for process automation requirements. This specific configuration features 16 valve ports (2x 3/2-way WWC per position), PROFIBUS DPV1 communication, and an aluminium AirLINE Quick adapter. 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. Key pneumatic functions ensure increased process reliability, such as check valves in the exhaust air ducts that make sure there is no unplanned actuation due to pressure peaks.

Advantages

• Safety-related shut-off of valves possible
• Higher plant availability with PROFINET S2 (system redundancy)
• Process reliability through pneumatic functions
• Optimised for installation at the bottom of the control cabinet
• EX-variants: ATEX / IECEx Zone 2, CCC, cURus HazLoc CL I, II, III Div 2

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
• This 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

Installation situation of the valve terminal inside the control cabinet

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.

Safety Instructions for EX Zones

• Danger from voltage: Before working on the device or system, disconnect the power supply and secure against reactivation. In an existing explosive atmosphere, connection terminals for 24 V supply, SIA, EVS, and digital inputs may only be plugged in or unplugged when de-energized.
• Hot Swap restriction: The use of the Hot Swap function is prohibited in an existing explosive atmosphere. If it can be proven and ensured by 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: Sudden discharge of electrostatically charged devices or persons can cause an explosion hazard in the Ex area. Take appropriate measures to ensure that no electrostatic charge can occur.
