IT IS MOST IMPORTANT FOR YOUR SAFETY that you follow this procedure.
Go to the drive consoles on the right side of the dome floor.
Disable the telescope azimuth drives by removing the AD castell key.
Insert it into the red AD key-hole above it.
Remove the safety key with the castell key marked 'T'.
Enter your name and the time on the board.
Go to the basement and prepare to enter the plinth area.
It is dangerous to be in the basement if the telescope could be
activated. The person in the basement should keep this castell key and
only return it and activate the antenna drives when everyone is out
of the plinth.
You will need a pair of step-ladders, and preferably someone to hold
them steady, and a size 3 hex-key to bolt the inclinometers to their
mounting brackets. Enter via the plinth gate with the 'T' key.
Locate the holes in the observing floor above you lying directly above
the A-frame beams and half way along. The inclinometers bolt into mounting
plates on the beams. Mount No.2264 on the right A-frame, No.2267 on
the
left, with their long axes parallel to the beams, and the cable
connections pointing to the rear of the building.
Go - or get someone else to go - back onto the observing floor and lower
through the holes one end of the appropriate signal cable; the cables are
labelled to match the inclinometers by number. Wrap the cable around the
beam once or twice in order to prevent tension on the cable being
translated to the inclinometer, and plug the cable into the inclinometer.
Exit the basement, taking the step-ladders with you.
