COMPONENT APPLICATION CHARTS

NOTES FOR COMPONENT APPLICATION CHARTS
1. Tank Fill Process: The output state of the Recover solenoid is controlled to maintain 2.4 bar
(35 psi) in the accumulator.
2. Recover Process: The output state of the recover solenoid is controlled to maintain 0.55 bar
(8 psi) to 4.27 bar (62 psi) max. in the accumulator. The output state of the oil return solenoid
is initially activated for three seconds, and reactivated every 10 minutes thereafter depending
on the length of the recovery process.
3. Deep Recover Process: The output state of the oil return and recycle solenoids are controlled
to maintain 0 to 207 mbar (3 psi) in the accumulator.
4. Vacuum Process: The unit may purge air in the background of the vacuum process.
5. Recycle/Power Charge Process: If the unit does not complete a full charge, the compressor
and recycle solenoid, cycle to build tank pressure.
