The device is designed for the open-loop control and closed-loop control of media.
The device must not be exposed to direct sunlight.•
Pulsating direct voltage (rectified alternating voltage without smoothing) must not be used as power supply.•
During use observe the permitted data, the operating conditions and conditions of use specified in the con-•
tract documents and operating instructions, as described in chapter “System Description” - “Technical Data”
in this manual and in the valve manual for the respective pneumatically actuated valve.
The device may be used only in conjunction with third-party devices and components recommended and •
authorised by Bürkert.
In view of the wide range of possible application cases, check whether the positioner is suitable for the spe-•
cific application case and check this out if required.
Correct transportation, correct storage and installation and careful use and maintenance are essential for reli-•
able and faultless operation.
Use the positioner Type 8792 and Type 8793 only as intended.•

The device contains electronic components which react sensitively to electrostatic discharge (ESD). Contact
with electrostatically charged persons or objects is hazardous to these components. In the worst case scenario,
they will be destroyed immediately or will fail after start-up.
Observe the requirements in accordance with EN 61340-5-1 and 5-2 to minimise or avoid the possibility of •
damage caused by sudden electrostatic discharge!
Also ensure that you do not touch electronic components when the power supply voltage is present! •
