Setting
Two different setting possibilities are available:
−
Standard setting: Normal calibration procedure (factory
setting). Only dark-on switching can be implemented
with this setting.
−
Fine detection setting: To be used only when the
standard setting does not achieve the desired results,
i.e., if the contrast differences are too slight. The fine
setting can also be used to implement both light-on and
dark-on switching.
Calibration procedure (Teach-in)
Standard setting: (for dark-on operation only)
In this configuration the sensor detects objects having a
lower light intensity than their background.
1. Position the target or mark.
2. Press the SET button until the bi-color LED turns off.
3. Release the SET button and wait for the LED to come
on green. The sensor is ready. The yellow LED comes
on as soon as the object or mark is detected and the
output is active.
Fine detection setting (light- or dark-on):
This mode allows finer contrast differences to be
distinguished.
The sensor automatically selects the correct method:
Light-on for objects or marks which are brighter than the
background, and dark-on for objects or marks which are
darker than the background.
1. Position the target or mark.
2. Hold the SET button down until the bi-color LED goes
out and then flashes green. Then release the SET
button.
3. Place the background in the beam path.
4. Hold down the SET button again until the bi-color LED
goes out. The sensor is ready. The yellow LED comes
on as soon as the object or mark is detected and the
output is active.
