Key to diagram:
6 Valve block
102-2 Filter (series equipment)
626-C Shut-off tap
for left-side tailgate cylinder Is combined with 626-D and 626-E.
626-D Shut-off tap
for right-side tailgate cylinder. Is combined with 626-C and 626-E.
626-E Shut-off tap
for belt tensioner cylinder. Is combined with 626-B and 626-C.
- blocked when 626-C and 626-D are open.
- open when 626-C and 626-D are blocked.
731-4 Non-return valve
734-1
734-2
Lock-up valve unit non-return valve
shuts off the tailgate hydraulic cylinders (318), the rotor cut-out clutch (338) and the drive clutch
(370).
754 Pressure relief valve
maintains the pressure in the tensioning arm circuit at 10 bar.
755 Flow controller
controls the volume flow for opening the tailgate to 50 l/min. The non-return valve does actually not
exist – here it serves merely for better understanding of the circuit diagram.
756 Flow controller
controls the volume flow for closing the tailgate to 18 l/min. The non-return valve does actually not
exist – here it serves merely for better understanding of the circuit diagram.
Y50 Baling pressure build-up solenoid valve
- limits the pressure in the tensioning arm circuit and thus controls the baling pressure.
- is controlled by the electronic box (the desired baling pressure is set by a potentiometer).
- when the power supply fails, the highest baling pressure is reached.
