BURKERT 20032237 Type 8652 AirLINE is a 12-bank valve island optimized for process automation requirements. This specific configuration features Industrial Ethernet connectivity (PROFINET IO, EtherNet IP, Modbus TCP, EtherCAT, CC-Link IE Field Basic), D10 and D6 brass ports, and an aluminium AirLINE Quick adapter. New diagnostic functions can be visualized 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 optimized 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.

• 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

The Type 8652 supports various circuit functions including standard and SIA variants (for safety-related shut-off). The 20032237 model is configured with 5/3-way mid-position closed WWL valves.

Symbol	Description
CF C	3/2-way solenoid valve, servo-controlled, normally closed
CF D	2 × 3/2-way solenoid valve, servo-controlled, normally open
CF H	5/2-way solenoid valve, servo-controlled. Pressure applied via port (1), therefore one of the two ports (2) or (4) is under pressure.
CF L	5/3-way solenoid valve. In middle position all ports locked
CF M	5/3-way solenoid valve. In middle position ports 2 and 4 ventilated
CF N	5/3-way solenoid valve. In middle position ports 2 and 4 exhausted

Product Connections

Power supply for communication and displays: Connect 5-pin spring-loaded terminal according to the pin assignment (24 V DC, CAN_H, SHIELDING, CAN_L, GND).

Power supply for pneumatic valves: The interface plate has a 2-pin spring-loaded terminal to which the pneumatic valves’ power supply is connected (AUX 24 V, GND).

Industrial Ethernet Interface: RJ45 interface for PROFINET IO, EtherNet/IP, Modbus TCP, EtherCAT, CC-Link IE Field Basic, or PROFINET S2.

Installation Notes

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.

Supplementary Instructions for EX Areas

DANGER

Danger from electrical voltage and electrostatic charge in explosive atmospheres:

• Before working on the device or system, switch off 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 the power is switched off.
• The use of the Hot Swap function is prohibited in an existing explosive atmosphere.
• 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.

WARNING

Special conditions for safe use:

• For type of protection "ec", install the device in an enclosure that meets the requirements of EN/IEC 60079-0 and EN/IEC 60079-7, with a degree of protection of at least IP54.
• For type of protection "tc" (dust), install the device in an enclosure that meets the requirements of EN/IEC 60079-0 and EN/IEC 60079-31, with a degree of protection of at least IP6X.
• Only use the device in an area of at least pollution degree 2 as defined in IEC 60664-1.
