 Move actuator to position "OPEN" (CCW). For this, energize terminal 1.
Limit switch S1 is activated.
 Move actuator to position "CLOSED" (CW). For this, energize terminal 2.
Limit switch S2 is activated.
 Move actuator to middle position (CCW/CW). For this, energize terminal 3.

15.5 Setting the end positions

In order to set the opening angle from 90° to 180°:
 Turn switching cam 2 of limit switch S2 by 90 ° anti-clockwise (seen from above).
 Reconnect the device to the supply voltage.
 Move the actuator into position "CLOSED" (terminal 2 energized).
 Readjust cam 2 until the desired end position is reached (see position of the ball).
