MOS troubles and solutions

If nothing about MOS starts moving when MOS commands are sent, there are some troubles.

• When the MOS is moving normally, "MOS moving...." is displayed in the CD terminal. MOS move may take 2 min. Wait until this message disappears with patience.
• However, the MOS moving messages continue appearing over 5 min., there could be something wrong.
  

Solutions:

MOS failure is very serious, so try to solve the problem deliberately. Be sure to go through the reset process from the top. The more powerful the reset, the further down you go. 

Solution 1: Just restart CD

1. Do "CD exit" in "processes" in UI.
• If CD dose not respond, quit CD with Ctrl+C on the CD screen.
  
2. Press "CD" button on the FALCONMENU to restart CD.
6. Wait for the all UI buttons turns into green. It may take a minute. Then press "Get All Status" button on the UI.
6. Be sure to initialize MOS by "Init" before continuing the observation.

Solution 2: Initialize MOS sequencer remotely

1. Quite CD as shown above.
2. Log into FOCAS2 with falcon account, and type "mos.java /dev/cua/10".
3. Type "CR" and send <ENTER> on the mos.java program.
• If "CC" message is returned, it is OK.
• In case of no response, go to the solution 3 below.
  
4. Issue "recover" command in the mos.java program.
• It will take ~5 minutes. (This is similar to issuing MOS init from the UI.)
  
5. Quit the mos.java program by typing "exit".
   
6. Press "CD" button on the FALCONMENU to restart CD.
6. Be sure to initialize MOS by "Init" before continuing the observation.

Solution 3: Initialize MOS sequencer locally

1. Cycle the MOS breaker (turn it off and on. Take some time.) in the power distribution box of FOCAS in the dome.
2. When necessary, move the telescope to zenith to access the power distribution box.
3. Follow the solution 2 above to start mos.java to recover it.
6. Press "CD" button on the FALCONMENU to restart CD.
6. Be sure to initialize MOS by "Init" before continuing the observation.
