Sometimes, inaccurate balance or incorrect
position is caused by the breakage of the press
sensor. The changing method of the sensor is as
following:
(1)Remove the upper cover and the right side
panel of the balancer.
(2)Detach the nut1 and 2, elastic washer, plain
washer and large flat washer.
(3)Loose the back nut3.4.5 to detach every parts.
(4)Change the new sensors and tight the
dual-head screw and then tight nut 5. The
installation
of the negative and positive pole of the
piezoelectric ceramics disk of the sensor must
follow the picture.
(5)Use the spanner to tight the nut4 and then nut
3. At this moment, you should pay attention
to the horizontal and vertical sensor screws
should be vertical. And the end of the screws
should be just fallen into the 2 holes. Mount the
nut1 and 2, elastic washer, plain washer and
large flat washer and completely tight them.
Usually, lock nut 1 and then nut 2. We require to
flat the elastic washer and then return the nut
1/4
—1/2turn. Use this way to get the normal
pre-pressure of the press sensor
（
use torque
wrench to lock and the torque is 40NM
）
There are
glass glue coat on the surface of the press sensor
and the normal installation result of the
piezoelectric ceramics disk of the sensor is the IR
should be larger than 50MΩ.
(6) Discharge the output line of the shortcuts
press sensor
，
insert into the computer board after
discharge to avoid the breakage of the computer
board.
(7) Insert the vertical
