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 Switch 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..
Yacht water level control, sewage level control.
Hydraulic oil tank level measurement and control
Ambient Conditions: Relative Humidity: 0-98 % RH Ambient temperature: 60 °C (It is not used under -20 °C)
1.3. Working Principle
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. The changes of the reed sensors with alarm or a level information can be assessable
with a relay circuit or a control device.The advantages of providing the analog output in the enclosure are preferred by the users.
1.4. Reed Relay and Operation Conditions
Advantages:
*A variety of materials according to the flow

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.

knows the safeguards.
Do not apply force to the instrument during the installation!
Do not use the Level switch 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 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 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 switch 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.
