8.12.4.3 Analog dynamic teach-in
The analog dynamic teach-in assigns to the lower threshold of the current or voltage range the minimum received
light value TPmin, and to the upper threshold the maximum received light value TPmax detected during the
running process between the start and stop of teach-in.

Perform a fast analog dynamic teach-in by pressing and holding (1second)
TEACH (confirmation teach-in start) and then pressing and holding (1second)
TEACH (confirmation teach-in stop).
The assignment of the received light values to the upper (UT) and lower thresh‐
old (LT) of the current or voltage range is done during the running process.
The maximum and minimum received light values between the start and stop
of teach-in are determined as the teach-in points (TPmax, TPmin). The upper
threshold (20mA/10V/5V) of the current or voltage range is assigned to
TPmax and the lower threshold (4mA/0V/1V) to TPmin. After the update,
the display returns to run mode.
