3.5 Setting of the limit switches
3.5.1 Dynamic 121 - 128
Close the door manually.
Remove the door operator's transparent cover.
Release the switching spindle by shifting the red no-load lever (50) forward and
pressing the wheel's inner door link disc (51) towards the spindle (see fig. C/1).
Turn the knurled wheel (52) clockwise until the switching carriage (53) actuates
the 'CLOSE' limit switch. The red LED (54) lights up (see fig. C/1). Relatch the
door link disc and make secure by re-engaging the no-load lever (makes an
audible click on engaging), as shown in fig. C/2. If necessary, re-adjust the
setting via the fine adjustment facility (55) on the switching carriage; turn the
adjusting cam clockwise: the operator cuts off earlier.
