April 5, 2026: LEMON Manuals is launched! Read the announcement.

Key-off monitor sequence is 1 to 8

  1. Atmospheric pressure 
    ATMOSPHERIC PRESSURE

    Next sequence is run if following condition set -
    Atmospheric pressure change for 10 sec. Less than 2.25 mmHg (0.3 kPa) for 1 second.
  2. First reference pressure 
    REFERENCE PRESSURE

    Next sequence is run if all of following conditions set Condition 1, 2 and 3
    1. FTP when 4 seconds. after reference pressure measurement -7.5 mmHg (-1 kPa) or less
    2. Reference pressure -36.4 to -7.93 mmHg (-4.85 to -1.057 kPa)
    3. Reference pressure Saturated
  3. Vent valve stuck closed check 
    VENT VALVE STUCK CLOSED CHECK

    Next sequence is run if following condition set -
    FTP change for 10 seconds. after vent valve ON (closed) 2.25 mmHg (0.3 kPa) or more
  4. Vacuum introduction and leak 
    VACUUM INTRODUCTION AND LEAK

    Next sequence is run if both of following conditions set Condition 1 and 2
    1. Vacuum introduction time 12 minutes. or less
    2. FTP FTP was saturated
  5. Purge VSV stuck closed check 
    PURGE VSV STUCK CLOSED CHECK

    Next sequence is run if following condition set -
    FTP change for 10 seconds. after purge VSV ON (open) 2.25 mmHg (0.3 kPa) or more
  6. Second reference pressure measurement 
    SECOND REFERENCE PRESSURE MEASUREMENT

    Next sequence is run if all of following conditions set Condition 1, 2, 3 and 4
    1. FTP when 4 seconds. after reference pressure measurement -7.5 mmHg (-1 kPa) or less
    2. Reference pressure -36.4 to -7.92 mmHg (-4.85 to -1.057 kPa)
    3. Reference pressure Saturated
    4. Reference pressure difference between first and second 5.25 mmHg (0.7 kPa) or less
  7. Leak check 
    LEAK CHECK

    Next sequence is run if following condition set -
    FTP when vacuum introduction was complete Second reference pressure or less
  8. Atmospheric pressure 
    ATMOSPHERIC PRESSURE

    Monitor is complete if following 2.25 mmHg (0.3 kPa) or less
    Atmospheric pressure difference between sequence 1 and 8 2.25 mmHg (0.3 kPa) or less
