seating of the conduit-thread screw connectors on the
plugs. If necessary, tighten them.
4.1.3 Positioning the limit switches
In order that the Local control unit can function faultlessly, the
limit switches must be positioned as follows:
1. Move the fittings into a defined end position (key-oper-
ated switch to HAND/LOCAL, knob-operated switch to
AUF/OPEN or ZU/CLOSE).
2. Position the appropriate limit switch.
3. Repeat steps 1 and 2 for the other end position.
4. Compare the end positions with the signals from the indi-
cator lights in accordance with the table below.
