6.1,16 PHASE 15 •ACCUMULATORRECHARGE A. After the time "accumulator re-charge delay has elapsed. the charger proportional solenoid valve AICA (67) is set to central position: the charger is ready to perform its cycle. B. The cylinder relief valve SC (46a) is open (coil de-energized). C. The cylinder filling control solenoid valve EVF (47) is open (coil energized), D. The pump pressure valve PR (21) closes (coil energized); the pressure rises in the system. E. In these conditions, the pump pressure valve PR (21) doses at a faster sped, since it receives pressure from both the pump (direct) and from the utilities system. F. The utility-cylinder selector solenoid valve (19b) is de-energized, the utilities system is open, but the high pressure system is closed. The utilities system and its accumulator (34) pressurize. G. The shake-out circuit and accumulator (3) also pressurize to the setting of the shake-out pressure reduction valve (40). Subsequently, the logic element (40c) closes, so trapping the pressure inside its body. H. The pressure transducer TRP (31) reads the value of the utilities system pressure, and delivers the signal to the electronics which, at the programmed value, open the pump pressure valve PR (21) and direct the pumps flow to the relief I The reties pressure selection logic element (16) self-closes due to areas difference, and so acts as a check valve trapping the pressure in the circuit.
