7.3 PRESS SENSOR INSTALLATION AND WIRING
Sometime, the troublesome of inaccuracy of balancing
and position if because the damage of the press sensor.
The method to change the press sensor is shown in the
following:
●Demount the upper cover and right side panel of the
wheel balancer.
●Remove the nut 1&2, elastic washer, sanding washer
and plain washer.
●Loose the nut 3, 4 and 5 to disassemble each part.
●Change the new sensor and mount the double head
screw and tight the nut 5.
●Use the spanner to tight nut 4 slightly and then tight
nut3. At this time, pay attention that the horizontal and
vertical sensor screw should to perpendicular to each
other. The end of the screw should fall into the center of
the hole with the gap of at least 1mm.
● Mount the plain washer, sanding washer, elastic
washer and nut1 and 2. It must be completely tight.
Generally speaking, you should fix the nut1 first and
then nut 2.）
●There is the glass glue protective coating on the
pressure sensor.
●Short cut connect of press sensor output cable to
discharge and then plug the cable discharged into the
computer board to avoid the high voltage to break down
the computer board.
● Plug the sensor plug according to the original
position.
●Calibrate the balancer once again and mount the
upper cover and side panel.
After change the computer board, phase sensor or the
press sensor, you must execute the self-calibration. In
the process to change the computer board, you should
setup the parameter according to the parameter
marked in the machine or the original board. You must
self-calibrate after changing
