Installation
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 limit switch contacts which are supplied by the factory in an open position. These
can be used for the feedback of the rotary actuator.
The limit switch contacts are actuated via two cams no. 13
(see “Figure 1”, page 10 and “Figure 2”, page 11).
• The white cam is used to record the opening process (FC1).
• The black cam is used to record the closing process (FC2).
Procedure:
→
Connect cable to the terminal strip 12 (see “Figure 1”, page 10 and “Figure 2”, page 11) according to the
schematic (see “Figure 19”).
