1 Introduction
Elixir-T-Uni is a vibrating fork level switch used for
level detection in storage tanks, mixing container and
pipelines in all kinds of liquid which do not react with
SS 316 whose viscosity does not exceed 10,000 cP.
It is suitable for most of the applications where float
switches were previously employed, as well as in
places where float switches were not appropriate (due
to deposition, turbulence, stresses and air bubbles).
Elixir-T-Uni ignores foam deposition on its fork tines.
Figure 1: Elixir-T-Uni
2 Operating Principle
A specially shaped tuning fork is kept vibrating using
piezo-electric elements. Typically, the fork vibrates at its
natural frequency. The frequency of oscillation for the tun-
ing fork changes when immersed in liquids. The change in
frequency is detected by the microprocessor leading to a
switching decision.

9 Installation Guidelines
While installing the instrument, please take care of the
following points:
1. The instrument should be installed in horizontal or ver-
tical position only.
2. Observe that when installed directly under the mate-
rial inlet source, a canopy called baffle of appropriate
strength and size should be welded right above the in-
strument as shown.
Material Inlet Source
Baffle
Figure 3: Provision of Baffle
3. To prevent the ingress of moisture and water seepage
in side mounting position, the cable entries should al-
ways point downwards.
Figure 4: Cable Gland Arrangement
4. Secure the cover of housing tightly. Tighten the cable
glands.
5. Make all electrical connections as instructed in the
manual. Don’t power on the device before verifying
the connections.
6. 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.
7. 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.
10 Electrical Connections

11 Output Check Test
Hold the magnet at the target place of the instrument,
the current status of the switching LED and the PNP output
will change and when the magnet is released from the
target area the status of the switching LED and PNP output
is switched to there previous (original) state.
11.1 Output Indications
Green LED Glows When:
•Fork is Uncovered and Fail-safe is High
•Fork is Covered and Fail-safe is Low
Red LED Glows When:
•Fork is Covered and Fail-safe is High
•Fork is Uncovered and Fail-safe is Low
12 Error Indications
Fork Stops Vibrating
•When Red LED blinks continuously and Fail-safe is
High
•When Green LED blinks continuously and Fail-safe is
Low
Troubleshooting: The following reasons may be re-
sponsible for the absence of vibrations in the fork:
•The instrument is damaged.
•Heavy build-up of application medium can dampen the
fork oscillations. In this case, the fork requires to be
cleaned.
•If material is very viscous, the fork vibrations will re-
sume when the fork is uncovered. In this case, the
error indication should be ignored.
No LED Glows
•This would happen in absence of power supply to the
instrument .

13.1 AS-Interface Topology
AS-Interface by design is a loop-powered digital bus.
The 2-wire unshielded lines carry power as well as data on
them. The single cabling system connects I/O devices with
automation systems as shown in Figure 9. ASi-3 is based
AS-i - AS-i +

13.6 Setting Up AS-Interface
Note: ASi-4 and ASi-5 are later versions of the AS-i
protocol. However, ASi-3 version is the most preva-
lent. ASi-4 & ASi-5 are backwards compatible with
ASi-3.
AS-Interface can set up easily using a PLC with AS-
Interface bus input. Follow these steps for setting up the
AS-Interface bus with Elixir-T-Uni:
•Set Unique Bus ID: Default set address(extended) is
1a (HEX) & can be change using ASi programming unit
by selecting default address zero. Each device should
have a unique bus identification. For setting the ID,
there needs to be single device connected to the AS-
Interface, other slaves need to be disconnected from
the bus.
•Check Configuration: Use the magnet to observe the
changes in D0 bit for the assigned address.When mag-
net placed at the target area of the instrument, cur-
rent status of switching-LED and D0 bit will change
and when the magnet is released; the status of the
switching-LED and D0 bit will changed to the previous
(original) state. The output change can observed via a
PLC or a SCADA system connected to the PLC.
