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.


Initial Conditions

A) None.

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.

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.

4.1 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.

5.1 Go to the control station on the structure platform. Turn on the monitor and move both mice around on the table top.

5.2 After doing a ‘Ctrl Shift 2’ exit out of the SPS software.

5.3 Do a ‘Ctrl Shift 3’ to bring up the PMC computer. Once the lines ‘SPSSTARTING… and PMCMain.. are written on the shell, go back to the SPS computer and double click on the latest SPS version icon. This will restart the SPS software.

5.4 Now go back to the PMC computer. Watch as the software scrolls down through the actuators. It should scroll right through them without hesitation. If it does not, repeat the process. Once completed turn the monitor off.

A) Notable glycol puddles and/or leaks are found.

1) Call and/or send email to the appropriate day staff and notify them of the problem.
