Electrical functions

The illustration below shows the relationship between the rotary angle, the adjustable switching points for auxiliary switches A and B, and the positioning signal.

Gear train rotary range

Inner mechanical limits

Auxiliary switches

Factory setting:

A = 5°; B = 85°

Setting range 5°…90°

Switching states

Rotary movement as a function of the positioning signal

Modulating signal, DC 0…10 V

AC 24 V/DC 24…48 V

➀ no movement (G,G0,Y=U)

➁ opening (G,G0,Y>U)

➂ closing (G,G0,Y<U or G,G0)

➃ Spring return function

(no voltage)

Tree-position signal

AC 24 V/DC 24…48 V
➄ no movement (G,G0)

➅ opening (G,G0,Y1)

➆ closing (G,G0,Y2
or G,G0,Y1,Y2)

➇ Spring return function

(no voltage)

Two-position signal

AC 24 V/DC 24…48 V;
AC 230 V

➈ opening (G,G0 or L,N)

➉ Spring return function
(no voltage)

Note

The setting shafts for the auxiliary switches turn together with the adapter. The scales thus only refer to the inner mechanical 0° limit.

Adjustment tool

The adjustment tool is used to set the auxiliary switches; it is part of the delivery (type-specific).
