The following procedure is for performing scheduled daily preventative maintenance on the Extended Range (ER) AERI.\u00a0 <\/span>All results are recorded on the PM checklist.<\/span><\/p>\n

Physical check of instrument<\/b><\/span><\/h3>\n

Inspection of front-end enclosure<\/span><\/strong><\/p>\n

Inspect the AERI outdoor front-end enclosure for damage, debris, or precipitation accumulation.\u00a0 <\/span>Check the the front panel and all hardware pieces are secure.\u00a0 <\/span>Check for signs of insect or bird activity.\u00a0 Check for obstructions on the exterior fan\/filter. \u00a0<\/span>Clear any debris or precipitation accumulation.<\/span><\/p>\n

Checklist Response:\u00a0<\/span><\/em><\/p>\n

No Problems Noted
\n<\/span>Problem \u2013 See CM Report<\/span><\/p>\n

Inspection of sky hatch assembly<\/span><\/strong><\/p>\n

Inspect the sky hatch for damage, debris, or precipitation accumulation.\u00a0 <\/span>Check that the hatch is clear of obstructions and can open freely.\u00a0 <\/span>Check that the internal rain sensor and external rain sensor are clean and free of damage.\u00a0 <\/span>Clean sensors with a KimWipe towel and distilled water if necessary.\u00a0 <\/span>Clear any debris or precipitation accumulation.<\/span><\/p>\n

Checklist Response: <\/span><\/em><\/p>\n

No Problems Noted
\n<\/span>Problem \u2013 See CM Report<\/span><\/p>\n

Sky hatch status<\/span><\/strong><\/p>\n

Observe and record the current hatch position.\u00a0 <\/span>Ensure the position is correct for current instrument and weather conditions. \u00a0If the hatch is closed and there is no precipitation, clean the blue surface of the rain sensor with water.<\/span><\/p>\n

Checklist Response: <\/span><\/em><\/p>\n

Open \u2013 No Problems Noted
\n<\/span>Open \u2013 Problem \u2013 See CM Report

\n<\/span>Problem \u2013 See CM Report<\/span><\/p>\n

Inspection of interferometer relative humidity<\/span><\/strong><\/p>\n

Check the relative humidity (RH) paper indicator on the desiccator tube on the left side of the interferometer box.\u00a0 <\/span>If RH > 20%, the desiccant should be changed (see instructions). A dry nitrogen purge can be run beforehand to dry out the interferometer box. Note: If RH > 30%, the ER-AERI optics (CsI beamsplitter) can get permanently damaged.<\/span><\/p>\n

Checklist response: <\/span><\/em><\/p>\n

RH < 20%
\n<\/span>RH > 20% \u2013 Desiccant was changed
\n<\/span>RH > 20% – Desiccant was not changed – See CM Report <\/span><\/p>\n

Functional check of instrument<\/b><\/span><\/h3>\n

Check of instrument power<\/span><\/strong><\/p>\n

Check that the instrument is powered on. Check that the green LED power indicators are lit on the Parker CompuMotor <\/span>(right) <\/span>and Connect Power DC-DC power <\/span>supply (left).<\/span> Check that the LINK and ACT LEDs are flashing on the interferometer <\/span>box (center).<\/span><\/p>\n

Checklist response: <\/span><\/em><\/p>\n

Instrument is Powered On
\n<\/span>Problem \u2013 See CM Report<\/span><\/p>\n

Check of displayed date\/time<\/span><\/strong><\/p>\n

Locate the date and time in the lower right corner of the computer display, and the lower right corner of FTSW window.\u00a0 <\/span>Compare with current SDS date\/time.<\/span><\/p>\n

Checklist response: <\/span><\/em><\/p>\n

Date and Time are Correct
\n<\/span>Problem \u2013 See CM Report<\/span><\/p>\n
