Displacement sensor (WS1) teach-in
29.0 Defining measuring range at displacement sensor
Note on teach-in procedure:
The teach-in procedure for the displacement sensor serves the
purpose of setting a precisely predefined measuring range at the
large pressure booster of the GAV 8000. The procedure precisely
sets the start and end points (= measuring range). Teach-in of
the measuring range is important in order to avoid faults and mal-
functions as the control software of the GAV 8000 evaluates the
measured values of the displacement sensor and refers them to
predefined, programmed values.
Quick guide:
- The measuring range must be taught in at the displacement
sensor WS1.
- The displacement sensor WS2 on the large pressure booster
and displacement sensor WS3 on the small pressure booster
are not taught in. They remain set to the factory setting. For
safety reasons, the calibration must be checked and reset to
the factory setting if necessary (see "Resetting to factory
setting").
Adjustment:
- The displacement sensor (WS1) teach-in proce-
dure must be carried out at the large pressure
booster in the GAV supply unit.
- Assemble the displacement sensor with the cable
end facing downward flush with the bottom face of
the sensor holder outside the supply unit and se-
cure.
- Plug the displacement sensor into the socket of the
wiring harness at the supply unit. Switch on supply
unit, operating voltage is now supplied to the dis-
placement sensor.
- Select "Calibration WS1, large pressure booster
calibration" on the display (see Section 9 "GAV
Settings - Large Pressure Booster").
- Press the sensor holder with the cable end facing
downward onto the right-hand tie rod, as viewed
from the hydraulic connection.
