In brakes that have optical detectors ( micro-switches ) mounted, on connecting/disconnecting the
brake the red LED of the detector must change status.
Fig. 25
Should any of the micro-switches not behave in the way described above it may be necessary to
readjust or replace the detector. Consult point 7.2 “ Replacement and adjustment of detectors
(micro-switches)”.
Check that the detector is clean.
Check that the rubber dust-cover fits and prevents the insertion of particles or light (in the case of
optical micro-switches ) in the detector.
Exposing of the microswitches to silicon gas may cause their dysfunction.
6.3 Winding verification:
Checking the resistance: Check that the resistance of the winding is correct. A reading below that
shown on the characteristics plate will be a sign that the winding has been damaged. In this case
it will be necessary to replace the brake as a whole. Consult the nominal value of the resistance
in section 1.5 “General characteristics” .
7 SPARE PARTS:
Spare parts are considered to be those components that may be replaced in the installation of
the lift without prejudice to the safety of the brake.
