Positive direction of
counting:
(View on shaft)
DIR = GND -> cw
DIR = +UB -> ccw
Set to zero:Set: Preset = +UB for 2 s
Deaktivate: Preset = GND
LED-behaviour:
At Start / while booting:- red gleam (< 2.3 s)
Malfunction:- constant red gleam (> 2.3 s)
Normal function:- constant green gleam
No supply:- no gleam
