The Burkert 20010137 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. Key pneumatic functions ensure increased process reliability, such as check valves in the exhaust air ducts to prevent unplanned actuation due to pressure peaks.

Key Features:

• 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

Circuit Functions

Standard Functions

• Circuit function C (CF C): 3/2-way solenoid valve, servo-controlled, normally closed.
• Circuit function D (CF D): 2 × 3/2-way solenoid valve, servo-controlled, normally open.
• Circuit function H (CF H): 5/2-way solenoid valve, servo-controlled.
• Circuit function L (CF L): 5/3-way solenoid valve, in middle position all ports locked.
• Circuit function M (CF M): 5/3-way solenoid valve, in middle position ports 2 and 4 ventilated.
• Circuit function N (CF N): 5/3-way solenoid valve, in middle position ports 2 and 4 exhausted.

SIA Variant (for safety-related shut-off)

Type 6534 valves are equipped with additional connection terminals. A valve circuit can therefore be interrupted by an external switch. Manual override is not required for these valve variants. To use the shut-off function, connect the terminal to a potential-free contact (mechanical switch or relay).

Dimensions

Variant 4-, 8- and 12-fold

Variant 16-, 20- and 24-fold

Product Installation

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.

Example Configuration

The following illustration shows a network with the example of AirLINE Type 8652 with Industrial Ethernet variant as master valve terminal and various AirLINE Type 8652 with büS variant as slave valve terminals.

Safety Instructions for Potentially Explosive Areas

Danger from Voltage

• Before working on the device or system, disconnect the power supply. Secure against reactivation.
• In a potentially explosive atmosphere, connection terminals for 24 V power supply, SIA, EVS, and digital inputs may only be plugged in or unplugged when de-energized.

Danger of Explosion from Electrostatic Charge

• Take appropriate measures to ensure that no electrostatic charge can occur in the potentially explosive area.
• Only clean the device surface by wiping it gently with a damp or antistatic cloth.

Special Conditions for Hot Swap

The use of the Hot Swap function is prohibited in a potentially explosive atmosphere. If it can be proven and ensured with suitable testing equipment that no explosive atmosphere is present for a certain period of time, it is permissible to remove/insert valves using Hot Swap during this time.
