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. This, therefore, enables a fast overview of the plant status.

The hardware is optimised for installation at the bottom of the control cabinet. Installation on a standard rail is, of course, also possible. 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.

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

Pneumatic Supply / Exhaust	Push-in D 10 mm, 3/8"
Pneumatic working ports	Push-in D 6 mm, 1/4"
Installation position	Control cabinet wall / Control cabinet floor

Circuit Functions

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

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.

Safety Instructions for Hazardous Locations

• Danger from voltage: Before working on the device or system, disconnect the power supply. Secure against reactivation.
• Explosion hazard due to electrostatic charge: In the event of a sudden discharge from electrostatically charged devices or individuals, there is a risk of explosion in the potentially explosive area. Only clean the device surface by wiping it gently with a damp or antistatic cloth.
• Hot Swap: The use of the Hot Swap function is prohibited in a present explosive atmosphere. If it can be proven and ensured with suitable test 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.
