Operating Instructions
Follow this manual and proceed in accordance with
the application conditions and specification data of
the device, as referred to in the data sheets. The
position indicator shall be integrated into the process
according to the general technical guidelines. Take
appropriate actions in order to avoid unintended
operation or mutual interference in the process.
Strict observance of these conditions by the user
ensures a reliable operation and a long service life.
Specific Use
The position indicator 1062 is designed for use to
electrical position feedback and optical position
indication. It can be fitted with the Bürkert valves
2000, 2001, 2002, 2030 and 2031.
Safety Rules
Safety rules must be observed. The position
indicator should be connected by trained staff only.
Caution: Disconnect voltage before opening any
position indicator! Do not switch the valve as long as
open - danger of injury !
