Check of output voltage U:
·
U = DC 0...10 V for angular rotation 90°.
Measures resistance changes while the actuator turns from 0 to 90°.
·
Switchover of the auxiliary switch contacts "A" and "B" as soon as the actuator
reaches the respective switching positions.
·
Set the setting shafts (part of the delivery) to the desired value by means of a
screwdriver (see section 3.2 "Angular range and mechanical limitation").
The angle values are valid only for the zero position of the actuator (clockwise
direction).
The auxiliary switches have the following factory settings:
·
Switch A: Switchover point at 5°
·
Switch B: Switchover point at 85°
The set direction of rotation must agree with the required
direction of rotation of the air damper..
Factory setting:
For the special diagrams according to section 9.4.2, the
operating states must also be checked.
