6.1 Connection
The VEGADIS 62 is an indicating and adjustment unit without external
energy for looping into 4 … 20 mA/HART circuits.
The parameter adjustment of the sensor is carried out via HART com-
munication. During the parameter adjustment, the VEGADIS 62 acts
as a Secondary Master with respect to the sensor.
