Generalinformation
5 sysTem DescripTiOn
5.1 intended application area
The feedback head Type 8685 and the control head Type 8686
are designed to be mounted on pneumatic actuators of valves Type
2036 for the control of media.
5.2 general description
The feedback head Type 8685 and the control head Type 8686 are
designed exclusively for integrated mounting on an actuator of the
diaphragm valve Type 2036 in sizes RV50, RV70, RV110.
The actuator size is adjusted with DIP switches.
The valve position is recorded by a permanent magnet on the
spindle extension. When a stroke movement occurs, the spindle
extension is guided along a reed sensor (lower/upper end position).
In addition to the electrical position feedback, the device status on
the feedback head and control head are represented visually by
colored LEDs. The status of the integrated pilot valve is also indi-
cated by LEDs for the control head.
In the variant with AS-Interface communication, bus status LEDs are
also active.
