To select the direction of rotation, choose the following menu on the AZL51...:

You are given the choice of «Standard» and «Reversed»:

When facing the end of the drive shaft
The parameter is filed in the basic unit so that the direction of rotation need not be
reentered when replacing the actuator.
This facility makes it possible to reset an already addressed actuator in the case of a
replacement, repair, or if addressing is wrong (wrong address assignment by the user).
For that purpose, the user must press the actuator's addressing button for at least 10
seconds when the actuator is in normal operation. The actuator will then reset its
address which is indicated by the LED when steady on.

The actuator gives the addressing number via the LED. The blink interval is 200
