HET
OPERATIONS ENGINEER MANUAL: INTERIOR
VISUAL INSPECTION (REV: 08.08.04)
General
Description:
Perform
a visual inspection of the interior of the HET.
Open exhaust fan covers (if required) and prepare the surface of the pier
for structure use. Restart the SPS
software. Inspect the spectrograph room,
lower and upper electrical rooms, and the mezzanine area.
1.0
Within the dome, inspect the floor area to the exterior of the pier.
1.1 Check the floor for
obstructions, fallen and/or broken parts, and anything that is unusual or out
of place.
1.2 Also, check that the door
that separates the viewing windows from the GTAG is shut.
1.3 Visually note the
approximate position of the tracker. Unless you are notified otherwise, the
tracker should be centered.
2.0
Normally the exhaust fans are not operated in conjunction with the ring
wall ventilation louvers. However if required, open the five exhaust fan covers
by pushing a switch on the right side of the fan cover support frame. Exhaust fan 11 is used for ventilating the
JLG only, so its cover is not opened.
3.0
Sweep the pier.
3.1 Sweep the top surface of the
pier using a special mop. The mop is
found to the right of the dome bay door hanging on a support girder.
3.2 Look for gouges in the
surface of the pier as it is swept.
These need to be filled by the day staff.
4.0
Inspect the floor to the interior of the pier.
4.1 Inspect the floor, including
underneath the cable wrap, for glycol puddles, fallen parts and anything else
that does not belong.
4.2 Look to be sure that there
are no cables or lines or any other foreign object that can become entangled in
the three position encoders of the structure.
5.0 Inspect the lower and upper electrical rooms
and the mezzanine area. Make sure all
lights are off if not in use.
6.0 Visually confirm tracker is in home position.
