1 Product description
1.1 Function and configuration
VEGADIS 50 is a digital indicating instrument
without external energy with adjustment possibility for surface or rail mounting with
LC-display for digital and quasianalogue
indication.
The indicating instrument can be connected
to all series 50 sensors (VEGASON,
VEGAPULS, VEGAFLEX) and to radar sensor VEGAPULS 81.
1.2 Types and versions
VEGADIS 50
Digital indicating instrument without external
energy for surface mounting.
With Ex-approval for surface mounting and
for mounting in zone 1 or zone 0.
Approval

2.1 Mounting instructions
The indicating instrument VEGADIS 50 can
be either mounted directly to the wall by
means of three screws ø 5 mm or plugged to
a rail 35 x 7,5 acc. to DIN EN 50 022.
Humidity
With wall mounting, the cable entries must
point to the bottom to avoid humidity ingress.
Loop the connection lines to the bottom.

Note:
Before starting connection work, switch off
the power supply of all components.
Loosen the four screws on the upper side of
the instrument of VEGADIS 50 and remove
the housing cover with the integral indicating
module.
The connection and adjustment of VEGADIS
50 can be facilitated by fastening the housing
cover with two screws laterally or displaced
to the bottom.
Connect VEGADIS 50 according to the following diagram.

4.2 Adjustment structure
Series 50 sensors can be adjusted
- with the PC (adjustment program VVO)
- with the detachable adjustment module
MINICOM
- with the HART®-handheld.
The adjustment must always be made with
only one adjustment medium. It is not possible to make the parameter adjustment at the
same time with the MINICOM and the HART®handheld.
Adjustment module MINICOM
With the adjustment module MINICOM you
adjust in the sensor or in the external indicating instrument VEGADIS 50. The adjustment
module enables via text display with 6-key
field the adjustment like with the adjustment
program VVO.

Screws
• The adjustment of the 6-key adjustment
module is stated in the operating instruction of the appropriately connected sensor.
• It has proven in practice to mark
VEGADIS. Information on the appropriate
measurement loop and the appropriate unit
of the indicated value help to avoid failures
and misunderstandings. A gap is provided
on the housing cover for marking. You can
glue in a label (48 x 11 mm) and mark it
appropriately. Example for such a label:
Meas. loop: F 37

Cleaning solvent
• Place the housing cover (3) again to the
housing (1) and tighten the four screws on
the upper side of the instrument.
