Structure and function
The control head Type 8695 can control single or double-acting process valves.
The control head Type 8695 has been optimized for the integrated modular fitting of series 21xx process valves
(ELEMENT) with actuator size ∅ 50. Various expansion stages are possible thanks to the modular design.
.
The valve position is recorded via a contactless, analog sensor element which automatically detects and saves the valve end positions by means of the teach function during start-up.
Option: Communication possible via IO-Link and büS.

10.1 Safety instructions
Warning!
Risk of injury from improper operation.
Improper operation may result in injuries as well as damage to the device and the area around it.
▶ Before start-up, ensure that the operating personnel are familiar with and completely understand the con tents of the operating instructions.
-
▶ Observe the safety instructions and intended use.
▶ Only adequately trained personnel may operate the equipment/the device.
10.2 Teach function: Determine end positions and save these, REV.2
• automatic teach function: For devices with pilot valve
The teach function automatically identifies and saves the end positions of the valve.
• Manual teach function: For devices without pilot valve
The end positions are captured and saved automatically.
10.2.1 Automatic teach function
For devices with pilot valve:
The teach function automatically identifies and saves the end positions of the valve.
With the IO-Link variant, the teach function can also be started with an acyclic IO-Link parameter (see parameter list) or with the Bürkert Communicator.
With the büS variant, the teach function can also be started with the Bürkert Communicator.
34 essential requirements:
• The device is mounted on the actuator.
• The supply voltage is connected.
• The compressed air supply is connected.
• So that the correct reference conditions are identified, the pilot pressure must correspond to the operating conditions.
