Commissioning
Check whether the voltage specified on the type plate mat-
ches the mains voltage available. The power socket used must
be earthed (protective earth conductor contact). Insert the
temperature measuring sensor (not included in the supply
schedule) into the 5-polar DIN-bushing at the rear of the instru-
ment. Put a magnetic bar into a vessel that is permeable for
magnetic field lines, and fill the vessel with the medium to be
processed. Put the vessel on the heating plate and immerse
the temperature measuring sensor into the medium (min.
20mm). Wit the enterprise without external temperature mea-
suring sensor see chapter 11.3. If these conditions are met,
the device is ready to operate after plugging in the mains plug.
If these procedures are not followed, safe operation cannot be
guaranteed and/or the equipment may be damaged.
Observe the ambient conditions (temperature, humidity, etc.)
listed under Technical Data.
