Figure 17: Three points mode
If voltage is applied simultaneously to terminals 2 and 3, terminal 2 is the leading one and the actuator
moves to the OPEN position.
procedure:
→
Loosen left cable gland 15 (see "Figure 1" and "Figure 2") and feed through the cable to be connected.
→
Connect cable according to the required control type (see "Figure 17" and "Figure 18") to the terminal strip Pos.
B of the power supply card (see "Figure 15" and "Figure 16").
Operating principle for Open / closed mode (see "Figure 18") :
• Switch open = actuator closes
• Switch closed = actuator opens
connecting feedback
The limit switches for the feedback are suitable for a maximum voltage of 250 V AC/DC – 5 A.
The rotary actuator features two additional limit switch contacts which are supplied by the factory in an open position.
These can be used for the feedback of the rotary actuator.
