Description of function:
Non-return valve (731-4) shuts off the pre-pressurizing circuit against the filter circuit.
Pressure relief valve (754) Maintains the pressure in the tensioning arm circuit at 10 bar.
Port (E) to the ram spaces of the tensioner cylinders.
Solenoid coil (M) Solenoid coil of Baling pressure build-up solenoid valve (Y50)
Baling pressure build-up
solenoid valve (Y50)
- limits the pressure in the tensioning arm circuit and thus controls the
baling pressure.
- Is actuated by the electronic box (the desired baling pressure is set
with a potentiometer).
- When power supply fails, the highest baling pressure is reached.
