Green LED illuminates continuously (ready)
Yellow LED on/off continuously (mark detected/not detected)
Increasing the switching threshold:
Reducing the switching threshold:
If the upper or lower end of the adjustment range is reached, the green and yellow LEDs flash at a considerably higher fre-
quency of 8Hz for the duration of one second.
Press the teach button
longer than 12s.
Only the green LED flashes.
Release teach button.
After releasing the button,
the yellow LED displays the state:
yellow LED on:pulse stretching ON
yellow LED off:pulse stretching OFF
Change is accepted.
Long press of the button =
large force expenditure =
increase switching
threshold
Each press of the button with
a duration between 200ms
and 2s increments the
switching threshold.
A press of the button is acknowledged by a
single, brief
flash of the green LED
– the
new switching threshold is now valid.
Short press of the button =
small force expenditure =
reduce switching threshold
Each press of the button with
a duration between 2ms and
200ms decrements the swit-
ching threshold.
A press of the button is acknowledged by a
single, brief
flash of the green LED
– the
new switching threshold is now valid.
