Programming the converter with a bar magnet
•
The converter can be programmed by means of the magnetic sensors mounted on the
face plate without removing the front lid (see Fig. 25).
•
To do this, a bar magnet (standard supply) is used to activate the sensors by holding the
magnet close to the glass window of the housing lid.
•
These sensors then duplicate the functions of the push buttons.

CAUTION:
For previous software versions P2.14 to P2.18, the maximum connecting cable length between
transducer (primary head) and MFC 081 F signal converter is 5 meters (16.25 feet). Previous
software version R2.18 and this version, P2.20, permit longer cable lengths up to 100 meters
(328 feet), unless limited by CE and/or hazardous location requirements. Also note that
software versions R2.18 and P2.20 have hardware changes in the MFC 081 converter, as
compared to converters incorporating earlier software versions.

Installation of the Converter MFC 081 F
In the compact version the converter is mounted directly onto the transducer.
In the separate version MFC 081 F (remote mounted) it has to be noticed that the readability
of the display depends on the lighting and the viewing angle. It should, therefore, be installed
at eye-level and in good lighting conditions but not exposed to direct sunlight. Refer to Section
D for dimensions of the MFC 081 converter.
Because of the rotatable housing it is easy to connect the wires for the power supply and the
input and outputs.
The installation of the power supply wiring must comply with local Electrical Codes.
