Installation & Handling Guide-
lines
The elixir can be installed in the vessel in almost any posi-
tion. Previously existing bosses welded in any direction can
be used. Since the fork can be screwed into a mounting
socket suitable for supplied mounting threads and the fork
length is comparatively short, it can be installed directly on
pipes too. For liquids with higher viscosities, top mounting
or side mounting with tines slanting downwards is preferred
as then the viscous liquid can drip off faster when the level
goes below the set point.
While installation of probe, please take care of the following
points:
•
The instrument shouldn’t block the material filling inlet.
•
Secure the cover of housing tightly. Tighten the cable
glands.
•
For side-mounting, provide a baffle to prevent the ma-
terial from falling on the fork. Please refer to Figure 6.
Figure 6: Provision of Baffle
•
When handling forks, do not lift them using their tines.
Please see Figure 7.
Figure 7: Instrument Handling
•
The tines should not be bent nor should their dimen-
sions be altered. Deforming the shape of the tines may
interfere with the fork’s operating frequency. Please
see Figure 8.
•
Make all electrical connections as instructed in the
manual. Don’t power on the device before verifying
connections.
•
To prevent the ingress of moisture and water seepage
in side mounting position, the cable entries should al-
ways point downwards.
Figure 8: Tines Handling
•
Weatherproofness of enclosure is guaranteed only if
the cover is in place glands adequately tightened.
Damage due to accidental entry of water can be
avoided if the instrument is installed in a rain shade.
•
If the ambient temperature is high, the instrument
should not be installed to receive direct sunlight. In
case such a position of shade is not available, a heat
shield should be fitted above the instrument especially
if the operating temperature lies between
60
◦
C and
80
◦
C.
•
While screwing the elixir instrument, the hexagonal
mounting bush should be turned and not the housing.

Calibration Settings
Follow the below procedure for calibrating the instrument
at notch point
•
To start with calibration, set calibration switch to
CLOSE position. (CLOSE is opposite of OPEN on the
DIP switch.)
•
Make sure that Status LED is not blinking for error.
•
Dip the fork till the notch point.
•
Then press ENTER.
•
The Status LED will blink in RED color.
•
Blinking indicates that elixir is registering the switch
point position.
•
Keep ENTER key pressed for 4 to 5 blinks.
•
Then release the ENTER key.
•
On Release, the status LED should :
- Turn RED for Maximum Failsafe Selection.
- Turn Green for Minimum Failsafe Selection.
- This indicates that calibration is correct.
•
Now test the calibration by dipping and removing the
tines from liquid.
•
During calibration, delays are automatically by-passed.
•
If calibration is correct, put the calibration switch back
to the OPEN position.
