Programming via teach-in button.
Easy programming:
Position reflector in the beam path, press button, ready:
LED confirms teach-in operation.
Two operating modes:
Standard setting: short Teach-in period (< 8 s); for standard applications;
approx. double reserve via switching threshold
Fine adjustment: long Teach-in period (> 8 s); for precise applications,
transparent objects. Small switching hysteresis.
