TANK FILL PROCESS
During the Tank Fill process the compressor, fan, HS and LS inlet solenoids, recover solenoid and oil return solenoid
are activated (see application chart). The output state of the recovery solenoid is controlled to maintain 2.4 bar
(35 psi) in the accumulator. When the ISV reaches the "target" weight, all components are deactivated.
