RESTORATION OF RAW AND SMOOTHED MAINS TO THE JKT BUILDING

  1. Ascertain the reason for the lack of power - in particular check that it has not been deliberately turned off while maintenance work is carried out. It is a local rule that any work of this nature should be entered in the Telescope Operations Log Book which is kept on the console. People carrying out work likely to endanger themselves or others must always write the nature of their work in this book and countersign it when their work is finished so that subsequent users know the telescope is safe again.
  2. If the reason was a "normal" power failure then the mains will come back automatically when power is available.
  3. If (2) was true and the mains is now back (lights and A/C on) but the computers are still dead (i.e. there is no power to the special red outlet sockets) then the mains frequency stabilizer and smoother (the Buffer Set) needs to be restarted. Don't be in a hurry to do this as power cuts often come in bursts. Contact the Duty Officer by means of an F9 call on the intercom before proceeding further. He should be able to advise you of what will be about to happen. In particular he may put the site on to local generator power for the rest of the night.
  4. Proceed to the plant room off the basement (down the spiral staircase). The Buffer Set is the LARGE GREEN BOX opposite the door.

    Follow the instructions (to the letter) as given on the notice. If in doubt call the duty officer or duty technician.

  5. Even though the Air Conditioning may be blowing a gale both in the control room and in the Clip centre, make sure that it is also COOLING properly since it is possible for the A/C to restart with the cooling disabled. If this is the case contact the duty technician. If you cannot find the duty technician in an emergency switch the A/C off in the Clip Centre, press RESET and switch on again. If no illuminated warnings come up, you are safe.
  6. If the restart of the Buffer set was successful then proceed IMMEDIATELY to check the status of the computers, their disc drives and the control computer CAMAC modules. See Section 2.5.
