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
It should be used in allowed using medium and application areas! It is not used in the corrosive mediums,
ambient with explosive and flammable material. Conformity with medium to be measured should be also taken into consideration.
Responsibility is not assumed in case of inappropriate use, modification and injure, and such cases are not covered by warranty.
Ambient Conditions: Relative Humidity: 5-95 %RH Ambient temperature: 70C (It is not used under -5 C)
1.3. Operating Princible
ELM level switches are used for checkin level of tank. It is preferred by machine manufacturers, especially in terms of its ease ofg use and
economy. The ELM level switched can be mounted in litte places because of their mini design. The switches are made by stainless steel
material and so can be used in various liquids.
When magnetic field of magnet in the float is aligned withreed sensor in the tube , it opens or closes
the electric circuit.When float moves away , sensor reverts back ( upon demand , drawn contact may be made).
Level informationcan be assessed with a relay circuit.

*Remove level switch 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 switch should be placed in completely vertical or horizantal position on the line.
*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 switch may be hot according
to situation of fluid, in this case, do not touch the switch, otherwise your
skin is damaged.
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.

2.6. Electrical Installation
Make the electrical connection of the instrument according to details on its label, table and cable figures in this manual.
Inductive 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.
