VEGA VEGATROL 10 Ex 1 - Manual (Page 13)

VEGATROL 10 Ex 1 13
Pre-requirements for set-up
- the sensor VEGATROL is installed in its final position
and the tuning fork is not covered
- the failure LED is dark
The set-up is carried out by pushing the set-up key for
approx. 4 secs.
During set-up, VEGATOR is adapted to VEGASWING. The
actual resonance frequency is detected as current by
VEGATOR and stored as reference value.
Condition up to approx. 4 secs. after set-up:
Yellow LED lights
Green LED in set-up key lights
Green LED lights
Condition up from approx. 4 secs. after set-up:
Green LED lights
Note:
- If the signal conditioning instrument VEGATOR
526 W Ex is exchanged by a new instrument of the
same type, the set-up must be repeated.
- The set-up of the continuous level measurement or
level detection is made acc. to the description in the TIB
of the signal conditioning instrument used.
3 Mounting and set-up
3.1 Mounting
The tuning fork of VEGASWING is marked, showing the
submersion depth up to the switch point. The marking
relates to liquid gas when the instrument is vertically
mounted (see 2.4 Dimensional drawings).
The switch point must be generally at 85 % of the vessel
volume.
The adaption to the respective vessel dimensions is
realized via dimensioning of the concentric tube.
Calculation help see supplement.
A sealing must be used between flange of VEGASWING
which is suitable for the use in liquid gas plants.
In case of installation lengths of VEGASWING exceeding
1,5 m the extension tube in the vessel must be protected
against bending (e.g. vibrations by fluctuating product). If
there is danger of mechanical damage, the extension tube
in the vessel must be protected against bending.
VEGASWING must be generally mounted vertically.
3.2 Set-up
After electrical connection of VEGASWING Ex to
VEGATOR 526 W Ex the overfill protection goes to
operating status.
Operating status before set-up:
Yellow LED lights
(= level relay de-energized)
Green LED in set-up key flashes
(= set-up not yet carried out)
Green LED lights
(= supply voltage on)
