General Instructions
•Instrument shouldn’t block the material filling inlet.
•Secure the cover of housing tightly. Tighten the cable glands. For side mounting, the cable glands should point downwards.
•For side mounting, provide a baffle to prevent the material from falling on the probe.
•When handling forks, do not lift them using their tines. While using them with solids, ensure that material size is less than 10mm.
•Deforming the shape of the tines may interfere with the fork’s operating frequency.
•Make all electrical connections as instructed in the manual. Don’t power on the device before verifying the connections.

1 Introduction
Vital-T is a vibrating fork level switch for level detection, it
is suitable for all kinds of solid which do not react with SS
316 .where the process temperature ranges between 0◦C
to +150◦C .
Figure 1: Vital-T
2 Operating Principle
A specially shaped tuning fork is kept vibrating using
piezo-electric elements. The oscillations of the fork dampen
when it comes in contact with the application material. The
loss of oscillation amplitude is detected and used for switch-
ing the output. The output contacts of the relay are in turn
used for annunciation and / or control.

8 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: Vital -T with 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.
9 Electrical Connections
Note: is compatible only with 24V DC power supply.
Note: does not have any keys to operate.The Fail-
safe feature has been implemented in accordance
with connection.
9.1 For Fail-safe High
If a device is mounted at top of the tank then follow the
instructions given below for Electrical Connections:
9.2 For Standard Connector

10 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.
10.1 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
11 Sensitivity
Note: Set the sensitivity value between 1-5.
Sensitivity of the tuning fork may have to be adjusted
depending on the density of material of the application
media.Vital-T has a LED display which helps in visualizing
the desired sensitivity level. The device ships with a default
sensitivity level .
•Magnetic key held at the target area of instrument the
current status of the PNP and Led output will change
and blue Led light flash two times, then released the
key.
•Again the same process will be proceed Hold magnetic
key at the target area of instrument and the current
status of the PNP and LED output will change and blue
led light blink two times then released the magnetic key
and led light will be consent.
•Enable for sensitivity process firstly, hold magnetic key
at the taget area of instrument at the 1 time and sen-
sitivity set 1. Same process will be proceed for set the
sensitivity.

Table 6: Error Indications
Troubleshooting: The following reasons may be responsible 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 resume when the fork is uncovered. In this case, the error indication
should be ignored.
