Pulse stretching option

Switching pulse stretching on or off:

"EasyTune" option - fine tuning of the switching threshold

Following power-on and completed teach event:

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.
