Operation Instructions
Sensitivity Adjustment
With no target present, press the teach button for
approximately three seconds until orange LEDs are flashing
synchronously: first threshold is taught. With the target
present, press the teach button for approximately one
second. If the green LED flashes and stays on then
thresholds have been taught, and the sensor is ready to
operate. If both LEDs are flashing synchronously then the
sensor cannot detect the object and no thresholds have been
taught.
Sensitivity Adjustment During a Running Process (optimum detection
of very small parts)
With the chosen running process being the only thing in the
scanning area, press the teach button for approximately three
seconds until orange LEDs are flashing synchronously. Press
the teach button until a minimum of one process cycle is
completed. If the green LED flashes and stays on then
thresholds have been taught, and the sensor is ready to
operate. If both LEDs are flashing synchronously then the
sensor cannot detect the target and no thresholds have been
taught.
L.O./D.O. Setup
Press the teach button for approximately 13 seconds. Orange
LEDs should flash alternately. When you release the button,
the green LED should remain flashing. When the green LED
is flashing, the output is inverted by pressing the button. The
orange LED shows active function. Do not press the button
for 10 seconds. The green LED stops flashing and the
present output function is saved. The sensor is ready to
operate.
Maximum Sensitivity
With no target present, press the teach button for
approximately three seconds until orange LEDs are flashing
synchronously. Again, with no target present, press the teach
button for one second. The sensor is set to maximum
sensitivity and is ready to operate.
Maximum Stability—Factory Setting (max. resistance to
contamination)
Cover the light source. Press and hold the teach button until
the orange LEDs are flashing synchronously. Keep the light
source covered, press the teach button for one second. The
sensor is set to maximum stability and is ready to operate.
Modification of the Emitter Frequency in Case of Mutual Interference
Switch one sensor off. Press the teach button during power
ON. The orange LED flashes one time; frequency one,
normal operation (switching frequency 2 kHz). Keep the
button pressed for another three to five seconds. The orange
LED flashes twice; frequency two, normal operation
(switching frequency 2 kHz). Keep the button pressed for
another three to five seconds. The orange LED flashes three
times; frequency one, detection of very small parts possible
(switching frequency 2 kHz). Keep the button pressed for
another three to five seconds. The orange LED flashes four
times; frequency two, detection of very small parts possible
(switching frequency 1.5 kHz). Release the button to place
the sensor in operating mode. Switch other sensor on again.
