Module 57 Hydraulic Balance
The hydraulic balance is included in the ECU 2 el-servo system.
The signal to the system comes from the 768-12 pressure sensor
in the left lift cylinder feed and from 768-14, right cylinder.
1. Calibration of the balance must be carried out in accordance
with the instructions in ECU 2 SETUP, points 20 and 21
2. Connect a loaded container to the machine
3. Extend the boom until the red lamp lights.
4. Lift the boom approx. 20 cm over the position where the red
flags on the left lift cylinder are aligned with each other.
5. Lower the boom until the red flags are exactly aligned with
each other.
(By first lifting the boom too high and then lowering it to the
correct position, the regeneration system is prevented from
building up pressure that can affect the measurement)
6. Press the button for weighing
= the vertical lift button on the control lever
7. The result is shown on the ECS terminal display
