4.5 Troubleshooting
4.5.1 Detection of a short-circuit
If the buzzer (7) emits a sound while there is no pressure on the platform, proceed as follows:
-
Unscrew the 6 A4 conical screws M8 (4) on the platform (2).
-
Remove platform (2) and connect the buzzer (7) to the connection cable (6).
-
Insert a screwdriver into the 2 holes of the lower frame (3a) and unscrew each of the
adjustment screws (5) until they do not touch the contact head any more (see Detail X).
If the sound continues, verify if the wiring or the frames (fix or mobile) are not in short-circuit
(mechanical or electrical connection).
4.5.2 No contact
If the buzzer (7) does not emit a sound during the sensitivity adjustment, proceed as follows:
-
Make sure that the platform (2) and the RBD (3) are correctly assembled; there must be a
visible movement (Paragraph
-
Make sure that the 2 adjustment screws (5) are not too far apart.
4.5.3 Sensitivity adjustment
If the sensitivity is out of the range between 13kg and 18kg (as indicated in paragraph
), make
an adjustment by proceeding as follows:
-
Connect the buzzer (7).
-
Insert a screwdriver in one of the holes of the lower frame (3a) then screw the adjustment
screw (5), facet after facet of the hexagonal head until the buzzer emits a sound.
-
Unscrew the adjustment screw (5) by turning it 4 facets backwards (0,16mm/facet).
-
Adjust the second screw (5) in the same way.
-
Make a test with the dynamometer (8) by pushing or pulling the upper frame (3b).
-
If the measured pressure is higher than 18kg, continue screwing the screw in and test at
every facet.
-
If pressure is lower than 13kg, unscrew and test at every facet.
It is recommended to proceed systematically with the adjustment (a regular play between the 2
contacts.
