System description
3.2.1 Explanation for System type "Frequency"
This adjustment of the I20 is used for applications to identify non-hardened or defective parts. The
parts are passed through a sensor C-frame in which they are exposed to an eddy current field.
Non-hardened or defective parts have a different field attenuation from good parts and can
therefore be separated.
Roland Electronic supports the use with no charge application tests in order to ensure the feasibility
of the project and obtain the optimum control unit adjustments.
Differences of the Adjustments of the I20 in Comparison to the Standard Use.
Teach-In
• Instead of the single sheet (1-sheet) part A is used for a teach in of 100%
• Instead of two sheets (2 sheets) part B is used for a teach in of 200%
Sensors
• The pair of sensors ISQ160S/IEQS160S is primarily used for the system type "Frequency".
• Depending of the results of the application tests, the transmitter and the receiver are
mounted in line either vertically (0°) or horizontally (90°).

Sensor Gap and Measuring Position
• The sensor gap must remain constant during the operating mode "Frequency".
The sensor bracket must be correspondingly designed for this purpose.
• The measurement position of the part to be tested must be identical during Teach-In and
measurement.
• For this application glass turntables are very well suited, magnetic transportation systems
are not recommended.
