Rotary movement:
Two-position control GMA12..1, GMA32..1
When operating voltage is supplied, the actuator must turn from 0° to 90° (or to end position for rotary angle limitation).
After interrupting the operating voltage, the actuator must return to the zero position.
Rotary movement:
Three-position control GMA13..1
Check the actuator operating states as follows (see also chapter 9.3 Connection diagrams (two-pos./three-pos.)).
Core connections |
Rotary direction | |
| AC 24 V | DC 24…48 V | |
| 1 – 6 (SN) / 2 – 6 (SP) | 2 – 6 (SP) | from 0° ⇒ 90° |
| 1 – 7 (SN) / 2 – 7 (SP) | 2 – 7 (SP) | from 90° ⇒ 0° |
| 1 – 6 / 1 – 7 or 2 – 6 / 2 – 7 open |
2 – 6 / 2 – 7 open | Actuator stays in position reached. |
| After interrupting the operating voltage, the actuator must return to the zero position. | ||
Note
Check the actuator operating states as per the truth table in chapter 9.3.
When applying a DC 10 V input signal, the actuator must turn from
0° ⇒ 90° / 90° ⇒ 0° (or to the end position of the rotary angle limitation).
Rotary movement:
Modulating control GMA16..1
After interrupting the operating voltage, the actuator must return to the mechanical zero position (spring return function).
After interrupting positioning signal Y, but while operating voltage is still supplied, the actuator returns to the zero position.
When the actuator moves from 0...90°, output voltage U = DC 0...10 V is generated as a position indication.
Characteristic function
GMA163.1, 164.1
Factory setting: The potentiometers for setting the offset Uo and span ΔU are set to the following values: Uo = 0 V, ΔU = 10 V.
Note
Specify the values set for Uo and ΔU in the plant papers.
Position indicator
GMA16..1
Check of output voltage: U = DC 0...10 V for rotary angle 90°.
Feedback potentiometer
GMA132.1
Measures resistance changes while the actuator turns.
Auxiliary switches
A and B
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 the adjustment tool. (See chapter 3.2, "Rotary range and mechanical limitation”.)
Important
The angle values are valid only for the zero position of the actuator and when no current is applied.
Factory setting
The auxiliary switches have the following settings:
Switch A: Switchover point at 5°.
Switch B: Switchover point at 85°.
