The 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. Moreover, 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.

INFO

The maximum flow rate depends on the valve function. Flow is reduced by approx. 3% with the integrated Hot Swap function.

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

AirLINE Quick Properties	Description
Adapter Plate Material	Stainless steel 1.4301 or Anodised aluminium
Pneumatic connection Material	Stainless steel 1.4401 or Nickel-plated brass
Pneumatic Supply / Exhaust	Push-in D 10 mm, 3/8"
Pneumatic working ports	Push-in D 6 mm, 1/4"

Circuit Functions

Circuit function	Description
C (CF C)	3/2-way solenoid valve, Servo-controlled, Normally closed
D (CF D)	2 × 3/2-way solenoid valve, Servo-controlled, Normally open
H (CF H)	5/2-way solenoid valve, Servo-controlled, Pressure applied via port (1)
L (CF L)	5/3-way solenoid valve, In middle position all ports locked
M (CF M)	5/3-way solenoid valve, In middle position ports 2 and 4 ventilated
N (CF N)	5/3-way solenoid valve, In middle position ports 2 and 4 exhausted
Z (CF Z)	5/2-way solenoid valve, Impulse variant with 2 coils

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.

Example Configuration

The following illustration shows a network with the example of AirLINE Type 8652 with Industrial Ethernet variant (PROFINET IO, EtherNet/IP, Modbus TCP, EtherCAT, CC-Link IE Field Basic) as master valve terminal and various AirLINE Type 8652 with büS variant as slave valve terminals.

Safety Instructions for Hazardous Locations

Danger from voltage and electrostatic charge

• Before working on the device or system, switch off the power supply. Secure against reactivation.
• In an existing explosive atmosphere, the connection terminals for 24 V supply, SIA, EVS, and digital inputs may only be plugged in or unplugged when the power is switched off.
• Take suitable measures to ensure that there is no electrostatic charge in the potentially explosive area. Only clean the device surfaces by wiping them gently with a damp or antistatic cloth.

Special conditions for using the Hot Swap function

The use of the Hot Swap function is prohibited in an existing explosive atmosphere. If it can be proven and ensured by means of 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.
