Pressure regulation is assured by two spool valves, one for \t\t left hand nozzle.\neach pressure mode. Pump series\nSwitching between low and high pressure is assured by a \"normally open\" 5 : hub Ø 32 mm\nby-pass solenoid valve. When this solenoid is non-activated, a by-pass channel Model number\nis open, allowing the normal functioning of the low pressure valve which sets the\nnozzle pressure. When this solenoid is activated, the by-pass channel is closed,\n AP 3 V 45 C 9 5 xx 4 P 07 00\nthus pressure will build up on both sides of the low pressure valve eliminating\nits effect, and the high pressure valve now determines the nozzle pressure. Revision number\nIn two pipe operation, the by-pass plug must be fitted in the return port, which\nensures that the oil dumped by the regulating valves is returned to the tank Installation\n P : by-pass plug installed\nand the suction line flow is equal to the gear set capacity. Bleeding in two pipe\n for two-pipe operation\noperation is automatic (it is assured by a bleed flat on the pistons), but it may\nbe accelerated by opening a pressure port. Solenoid coil voltage\nIn one pipe operation, the by-pass plug must be removed, and the return 05/07 : 220-240 V AC ; 50/60 Hz\nplugged. Oil which is not required at the nozzle is returned directly to the gear\ninlet via the pressure regulating valves, and the suction line flow is equal to Connector cable length\nthe nozzle flow. 00 : no cable\nA pressure port must be opened to bleed the system. 35 : 35 cm - 45 : 45 cm\n 60 : 60 cm - 10 : 1 m\nSPECIAL FEATURE\nCover pressure port only gives pressure in high mode.
