1.3. Working Princible
A palette selected according to the material is installed on the tip of the motorized level switch which can be installed on the tank wall. It revolves
idly with the revolution speed of the probe motor. Material to be detected reaches to the level of the palette and covers its circumference and
creates a counter-force according to the revolution force. Firstly, level information alarm contact is activated. Then, the other contact is
triggered and stops the motor. Adjustment of the spring in four different torque values according to specific weight of the material can be realized
by the user. When the material level at the end of the palette is decreased the created force is released and the motor starts to revolve, consequently,
changing the alarm position.

2. Installation :
2.1. General Notes
Installation of device must be done by only authorized staff, that has known about 2014/34/EU criterias,
for ensuring safety against explosion and liable against preventing harms to third party
Installation of the instrument should be made only by authorized staff.
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 to be damaged.
It should be guaranteed that there are not any magnetic particles.
Max. Working Pressure must 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 manufacturer.
*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 the characteristic curve.
*Level switch should be placed in completely vertical or horizantal position to the tank.
*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,please take precawtions to prevent any harm.
*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 can be harmed.
*Insulation of product must be done properly (It can be done externally or inside the 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. (Max.20 Nm for G1", Max.30 Nm for G1 1/4" and G1 1/2" )
It closes on
clockwise turn

2.5. Torque calibration mechanism :
Torque spring should be used for recalibration of shaft's output torque which is set as low and weak in factory settings.
Calibration of torque spring can be adjust to material's weight and density which is specified by customer.
If the density of measured material is high, please set the spring to strong position until to get optimal working conditions.
High torque setting must be choosen in materials that has adhesion tendency and moist properties.
Low torque setting must be choosen for materials that has low density and dry properties
