The robust and compact positioner is designed with standardisation according to IEC 60534-6-1 or VDI/VDE 3845 (IEC 60534-6-2) for assembly onto linear and rotary actuators. In addition, the variant with remote position sensor can be combined with Bürkert process control valves for closed-loop control. The digital electropneumatic positioner, SideCONTROL, can be operated with all standard current and voltage standard signals and can also optionally be equipped with the fieldbus interface. The positioner is equipped with additional diagnostic functions to monitor the valve. Valve diagnostic messages via status signals are issued in accordance with NE107 (NAMUR) and recorded as historical entries. The diagnostics can be used to monitor the operating conditions of the control valve which makes maintenance decisions predictable and optimises the availability of the plants as required. Operation occurs via the external operating and display module consisting of a graphic display with backlight. For the user, this results in very simple and clear operation, which is identical to the Bürkert ELEMENT Type 8692/8693 positioners and process controllers. The pneumatic actuating system can be used equally for single-acting and double-acting actuators. It features a defined safety response in the event of failure of the electrical or pneumatic power supply and has an enormous air capacity range with pressure supply up to 7 bar.
