3.4 Ex-separating chamber
When several instruments are mounted in a row, the
blue Ex-separating chamber must be plugged to the
terminals of the sensor input (terminals 1 and 2) on
VEGADIS 371 Ex, to ensure the required distance
(50 mm).
• Place the Ex-separating chamber acc. to the figure
to the terminals of the sensor input (terminals 1 and
2) and loop the sensor line to the front out of the Ex-
separating chamber.
• Push the Ex-separating chamber to the front until
snap-in.

When switching on voltage supply, the software
version of VEGADIS 371 is displayed for approx.
4 seconds.
Tipp:
For parameter adjustment of connected HART
sensors, sockets are integrated in the terminals of the
meas. data input. A VEGACONNECT can be
connected directly to these sockets without an additio-
nal HART resistor being necessary.
