Below are some of the important procedures which should be explained to a new observer. It also provides an example or two of some of the types of failures which may occur.
Before going through these proceedures, ask the observers to read the Parkes Observatory User Guide, Chapters Four and Five.
As you are going through the telescope indicate what all the rooms and levels of the telescope are and there purpose to the functioning of the telescope.
The checklist is:
Check the observer knows relevant usernames and new passwords (if they have changed). Also see if they have a NEXUS account, but if not tell them the visitor username and password.
Also, check they know the door combination to gain access to the tower.
Tell the observer that computing equipment for non-observing people is available in the user room in the Opera House and Upstairs Control Room (network connection for laptops is also available in both areas).
The scheduled observer has priority on machines in the control room.
Non-CSIRO staff should use the Pink Cables to plug ther laptops into. This provides limited access to the internal network.
If the observer has a laptop, check to make sure their wireless network card (if present) is turned OFF.
Make observers aware of Quarters breakfast, lunch and dinner times. If they wish to have a break for lunch, contact either John Sarkissian or Stacy Mader who will be happy to relieve them for a while.
Show the observer the WINDS display - data for 2 hours.
Each bar represents 120 seconds. The minimum is the average
over the last 120 seconds and the maximum is the peak (or gust)
in the last 120 seconds (which is why you sometimes see a plateau).
Wind stow algorithms operate on both average and peak values (see
tab:wind_park and the Maintenance display on SERVO;
CNTRL P M).
The WINDS display is critical for unstowing from a wind park. Wind Parks are automatic. If this fails you can see the wind speeds from SHOWTEL (VMS/UNIX versions), but notify call-out person (or Andrew Hunt if during office hours).
Explain the SHOWTEL display. Show observers how to switch between coordinate systems.
Show observer limits of the infrared detector in the control room.
For the Safety Timer, there are three main buttons. Green reset button, press within 14 min, 40 sec, otherwise the alarm sounds. The yellow button is for DCP contact, this must be checked when the DCP phone is moved or when the DCP goes to sleep by the tower observer pressing the DCP Button and the DCP then returning the call. DCP phone only required if one person in the tower. Explain what happens if 25 minutes passes before observer gets to it or when 35 minutes is reached.
Press the yellow button if you are tired and need to locate the DCP quickly.
Press the red button if there is a fire or if there is a the mains power failure and the generator won’t start.
Show the observer the location of SERVO, ME, PKDESK and YOWIE). Show cheat sheet on how to reboot each if required. Note if there is an issue with the ME PDP11, either staff (if during business hours) or the call-out person should be notified.
Show the observer the MCP. Show the user how to un-stow and stow the telescope. Explain the difference between stow and park. Get the user to un-stow and stow the telescope, get user to use the clear call system for telling people the telescope is moving. Explain the software and hardware limits on the display (top hardware limit light, bottom software limit light). Explain the north and south wraps (limit with cables). 15 minutes to do full azimuth and 6 minutes to reach the zenith.
Explain white and yellow safety tags. Stress that the telescope should not be moved if tag on MCP. Only the person who owns the tag can remove their tag.
Show observer SERVO/ME terminals on computer near the MCP. Show that to select a window, the user must click on the window they want before entering commands.
With SERVO, explain computer instructions with park or stopping the dish. Other commands are on laminated sheets.
With ME, only Andrew and Tim should do anything with this. Show the observer the ME room and problems with not locking due to birds, moths or other insects.
Show observer the three coloured lights outside the diesel hut. Their meaning is:
GREEN: Power is supplied by the council mains grid
BLUE: (flashing) Power is supplied from the diesel generator
RED: The diesel generator is running
There are three types of power failures.
1. Mains fails and returns almost immediately. Only have to reset the alarms near the MCP and the UPS room in the diesel shed. Telescope drives will also be disabled and must be re-enabled to restart observing.
2. Mains fails and the Generator doesn’t kick in straight away, this may take up to 6 minutes. You still need to reset the alarm near the MCP and in the diesel shed in small room.
3. Mains fails and the Generator doesn’t kick in. Ring Matt McFarland and the call-out person. Take the generator hut keys to generator hut. Go over to the hut, explain why the roller door must always be up (DON’T CLOSE). Make sure the ear muffs are on (located in cabinet near gate). Take note of the lights on display to tell Matt McFarland. Move switch from auto to off then auto again. Shut down all equipment on RED powerpoints to minimise UPS drain.
Remember to reset the UPS alarm, press the reset alarm, then the test alarm, then reset alarm button. This will set off the alarm in the upper control room next to the MCP, remember to reset it again.
Show the observer the web based fault, observer and wind park reports. Explain that these reports should be filled out and stress importance.
Show the observer the call-out board. Purpose of the call-out person, how to contact them. If unable to contact call-out person, try calling the friend or anyone from the telescope. Details in blue phone book.
Indicate to the observer possible "Important Notice" which may be displayed, including the whiteboard, notices above computers and the pin board.
Show the observer the location of the Manuals and Documentation in the control room and on the web.
If there is a Fire, the fire exhausters are located on the walls, they are not water based due to electrical equipment. If you are unable to put out the fire, try proceeding to the MCP to stow or park the disk, call the call-out person to ring Fire Brigade.
If dish is low and storm comes in quickly and there is a power failure and the generator won’t start, call Matt McFarland. Go over the generator shed and try starting the diesel manually, call Matt McFarland if this won’t work.
Stress that if they are unsure of any procedures associated with operating the telescope to contact the call-out person.
The Observatory has a number of alarms the observer should be aware of.
