1. General Information :
1.1. Material Acceptance
Check that there is no damage on the packages during the transportation immediately after the material acceptance. If packages are
damaged, open the packages immediately and check whether products are affected or not, if there is any damage, send your
complaint report to the transporter company and its photocopy to the address of our company.
1.2. Information about Areas of Use
Level Transmitter is designed for industrial plants. It should never be used in mines.
Otherwise, the responsibility of the manufacturer is eliminated.
Tank level measurement and control,boiler kontrol,store room control..
Ambient Conditions: Relative Humidity: 0-98 % RH Ambient temperature: 60 °C (It is not used under -20 °C)
1.3. Working Principle
DX-ELS-tx level transmitter are used for tank levels and for controls. In the float when the magnet magnetic area moves according to the
liquid in the tube, then the reed swicthes the electrical circuit on or off when it reaches the level of the sensor.Reed swicthes in and out.
The changes of the reed sensors with alarm or a level information can be assessable with a relay circuit or a control device.Sensitivity increases
according to reed sensor lowering range.The advantages of providing the analog output in the enclosure are preferred by the users.
1.4. Reed Relay and Operation Conditions

Inductive Load
Capacitive Load
When reed switch is used for loads such as electromagnetic relay ,contactor or solenoid, reed switch may be exposed to very high
voltage depending on value of inductive load. This causes either failure of switch or shortening its service life. Therefore, it is
recommended to be used as follows depending on used voltage, for the purpose of protection of switch.
When reed switch is used with capacitive load, it may cause that high current passes over reed switch, depending on value of
capacity during Charge '96 Discharge of capacity. So this may cause failure of switch. It is recommended to be used as follows
depending on used voltage, for the purpose of protection of switch.

2.1. General Notes :
The device installation is in 2014 / 34 / EU criteria to ensure the safety of atmosphere and people from explosions, must only be done by staff who
knows the safeguards.
Do not apply force to the instrument during the installation!
Do not use the Level transmitter with a greater pressure than recommended pressure.
Do not forget that instrument is precise, carry it carefully and prevent not to be damaged.
It should be guaranteed that there are not any magnetic particles.
The Max. working pesure should not be exceeded.
2.2. General Installation Stages
*Remove Level transmitter from the box carefully
*Check whether gasket is appropriate for fluid or not. If is not appropriate, contact with the producer.
*Then, apply below mentioned explanations according to structure of the design.
2.3. Special Notes
*Please ensure that there is no mechanical stress on the shaft following installation. Such case will cause slipping in thecharacteristic curve.
*Level transmitters must be placed upright or horizontal.
*Allocate valve certainly in the process connection while instrument is used.
*Allocate blowdown valve under bottom flange for blowdown.
*If instrument is mounted outside and if there is any danger of lightning or
excessive pressure, take preventive measures by taking necessary measures.
*In the operating conditions, level transmitter may be hot according
to situation of fluid, in this case, do not touch the indicator, otherwise your skin is damaged.
*The grounding product must be done properly. (can be done outside or in housing)
2.4. Installation For Mechanical Connections
*Use appropriate O-Ring or gasket for tightness.
*Ensure that its surface is clean and smooth.
*Assemble the instrument manually.
*Connect the contacts as shown in the figure.

WARNING !!!
Please pay attention to following matters in order to operate your level switch properly.
Do not pull the cable strongly,
otherwise the characteristics
might be changed.
Please keep away from magnetic materials
like iron board ; otherwise the
characteristics might be affected
Please do not drop ,
otherwise the characteristics
might be changed.
Please do not dip cables
potting into liquids,otherwise
instulation problem may cause.
Do not fasten switch reversely ,
otherwise its characteristics
might be changed.
Do not connect the switch in reverse.
Their characteristics may vary.
Vibration might be
caused instability.
Do not remove the plastic parts
of the bottom of the switch body ,
do not loosen.
In case vapour splash cable
potting points,insulation
problem may cause.
Excess current , to be drawn as
a result of direct connection to motor,
may burn relay of switch
Please avoid using with liquids which
damage materials of parts ,otherwise
quality can not be maintained accurately.
Please do not mount
slant way, otherwise
switch do not work correctly.

3. Failure Delection
Breakdown
Fluid is leaking
The analog isn't giving
signal or it's giving the
incorrect value.
Housing or body broken
There is an Unstable
work in the signal.
The thread is stripped.
Probable cause
-Hole in the body metarial.
-The socket may not contact
-The product has been exposed in a mangetic
ambient.
-Angle of connection is not right.
-Applied voltage above the value.
-Over tightening the screws during installation
-Product falling or impact from outside.
-The product has been left in a magnetic ambient.
-The product has been exposed in a vibration.
-Product exposure in high temperature.
-Been tightend with torks more than specified
during installation.
Failure detection\correction
-Check if their working under favorable conditions ,
contact the manufacturer.
-Check the socket connections.
-The magnetic field element must be removed or isolated.
-Fix the angle of the montage.
-Report to authorized service.
-Report to authorized service.
-The magnetic field element must be removed or isolated.
-Vibrations must be blocked from that will effect the product or must
connect where there is no vibration.
-Use in suitable temperature.
-Report to authorized service.
If you find an error, try to eliminate it by using this table or send the instrument to our service address for repair.
