allocated to the value 0 or 1.
ccw (counter clockwise) Turning the encoder shaft in counterclockwise
direction (in view of the shaft side of the encoder).

cw (clockwise) Turning the encoder shaft in clockwise direction
(in view of the shaft side of the encoder).

Zero signal The zero signal is emitted once per revolution, it can
be used e.g. as a reference signal during the first
revolution after power.
Temperature Working temperature: Operating temperature:

The higher the number the smaller the particles. The higher the number, the higher the water pressu-
