Figure 4-7. Tank Fill
TANK FILL PROCESS
During the Tank Fill process the compressor, fan, tank fill, and oil return solenoids are activated. The output state
of the tank fill solenoid is controlled to maintain 2.4 bar (35 psi) in the accumulator, and is based on the ambient
temperature which can vary depending on the temperature reading from the temperature sensor. When the ISV
reaches the “target” weight, all components are deactivated.
