Technical Systems Rollant 160 TIC Description of function: 2/2 Baling During baling, a pressure builds up in the hydraulic cylinders 318 (rod end) which can be read on pressure gauge 912. - Net wrapping At a baling pressure of 220 bar, oil pressure switch Z8 actuates the STOP signal light H42 and buzzer H44. - Twine wrapping At a baling pressure of 220 bar, oil pressure switch Z8 releases the automatic wrapping start. - Overload protection If the baling pressure rises above the pre-set value (260 +10 bar max.), pressure relief valve 752 opens, thus allowing the oil pressure to decrease towards the ram sides of hydraulic cylinders 318 = pressure compensation. The tailgate opens slightly.
Opening the tailgate The oil is pumped from port B of quick release coupling 801 via the pilot- controlled non-return valves 734-1 and 734-2 to the tailgate cylinders 318. The pressure in lock-up valve unit 734 which rises at the same time opens the lock-up valve unit and the oil flows via port A of the quick release coupling 801 into the tank. 2-4 RO-160 03/04
