Red signals mean one or more metrology signals may have gone too low and homing carts is necessary. The METDATA function on the ople gui can be used to sample the metrology signal and may show noise spikes that can be disruptive to the smooth cart motion. | + | * Are the carts behaving or are there vibrations or jumps of 100 or more microns every 3-6 seconds?

+ | ===== Can't find the star ===== | ||
+ | |||
+ | Sometimes the star does not appear on the ACQ camera and there are many reasons why this can happen. Here are some of those reasons. | ||
+ | |||
+ | * Did the telescope actually slew? If the powers are off or the scope is disabled, it will not slew. | ||
+ | * Did the telescope disable after slewing? Check the dome gui to see if it says it has disabled. Enable to get it going again. | ||
+ | * Are the M1 and M3 covers open? Check with the Telescope monitor or spycam 2 to see if the covers opened. | ||
+ | * Did the dome rotate with the scope? Check with Spycam 1 to see if it is blocking the telescope. Use Autodome On to get it in line with the telescope. | ||
+ | * Is the ACQ camera showing a live view. Hit ACQ or reopen to see a live view. If the server has quit, bootlaunch on the appropriate computer to restart the ACQ server. Sockman will tell which computer the server runs on. Should be wfs computer at each scope. | ||
+ | * Is the ACQ exposure appropriate for the star magnitude? Turn it up as needed to show the star. | ||
+ | * Has the default flat or last flat been loaded after a slew? A bad DM will distort dim stars and they will not be visible. | ||
+ | * Is the star too low or obstructed by a tree or dome? W1 and S2 have trees nearby that can obscure the star below 40 degrees. Refer to the horizon maps to see if they are the cause. | ||
+ | * E1 does not track past 218 degrees azimuth. The finder camera may be needed to find the star again. It will be off in azimuth, but should still show in the finder. | ||

When the communications are good, each active cart will be displayed in the ople server or ople gui status tab as before. At times, an ople computer can lose communications or a server can crash and the server or comms needs to be restarted. |

- | Have the powers been turned on to the drives? Are the scopes disabled? The usual state of the telescopes is disabled until enabled. This is due to the stall function of the scopes which eventually disables the scopes when they are stowed. Enable the scopes by hitting [ENABLE] on the dome gui, the telescope gui control tab, or the bottom of the obsgtk. If a scope disables itself during a slew, it may be just an overcautious stall function or the slew gains may be too high or low. Check the gains and if they are OK, Hit ENABLE and the scope should continue to slew. If it disables again without moving, there may be something wrong at the scope, ie. a hatch left open, a ladder not put away, a tool on the floor, or something else physically impeding the motion of the scope. You will need to go to the dome to see what it is. The computer in the dome will give you control of the scope to turn it away from the problem. | + | Have the powers been turned on to the drives?

Sometimes the dome guis get hung up and can cause erratic motion or no motion of the scopes. Check them for current times and continuous updates of numbers. If they are not updating, try to REOPEN them first. If that does not work, close the gui and open a new one. If a new one does not open, the dome server may be dead or Sockman lost track of it.

+ | ==== The Telescope won't track ==== | ||
+ | |||
+ | If a bright star is manually found and not slewed to by number, (usually after the scope has gotten lost), the telescope will not track as it does not know it has gone to a star. When you init the EL and AZ position of the scope to the star's position, you must enable the tracking by going to the dome gui, selecting the RA/DEC tab and hitting the [GO RA/DEC] button. The scope will track, but the pointing model may still be off. Try slewing to the same star and initing on it after it is locked in Tiptilt. This can be done in the dome with the computer at the telescope. | ||

The HUT servers control functions such as beacon and dichroic movements, heater and dehumidifier usage, and various AO functions. An observer may find that the obsgtk is no longer controlling the beacon LED's, beacon flat or dichroic alignments. This happens on occasion with E2 and other scopes. The HUT server may be the cause if it has quit or lost connection or the AOB may be at fault. To see if it is the server, open the HUT gui for the desired telescope from the CHARA menu. If the alignments can be changed from the gui, then the HUT server is ok. You can use the hut gui to continue observing. If the hut gui gives move error messages, cycle the power on the AOB and open a new hut server to restore the connection to the obsgtk. On the POWER gui, turn off the power to the AOB for the offending telescope and turn it back on. Stop the hut server by logging into the appropriate telescope computer and identifying the PID with the bootlaunch_master command and killing the process with the kill -9 #### command. Start the new server via the bootlaunch_master command. Hit REOPEN on the obsgtk to reopen the connection to the HUT server and hit reopen on Cosmic Debris as well. | The HUT servers control functions such as beacon and dichroic movements, heater and dehumidifier usage, and various AO functions.

If the cart has no issue, it will arrive at the target position of 0m and the home switch at the same time. The X in the OPLE server under the HM will indicate it has stopped on the home switch. If a cart does not reach the home switch when it returns to position 0m, it was lost and likely the cause of the difficulty in finding fringes. The X does not guarantee the cart has retained its home position. This home position can be checked by using the CHECK button on the ople gui or by typing the command |

+ | ==== Metrology ==== | ||
+ | |||
+ | * Good metrology signals are important to the proper positioning of the carts. Monitor the signal strength by running [RUN MULTIPLE] on the Metrology Monitor. Place the windows above the TV windows for each scope you are using. They should show white sine waves that are around the height of the window. Erratic, fluctuating waves indicate self-interference or a weak signal. This may cause the carts to lose their place as the signal strength falls too low. Red waves indicate that some displayed signal has gone too low and the carts will all need to be homed. A careful adjustment of the MET2 mirror can sometimes bring the signal back. Do not adjust the MET1 mirror | ||
+ | |||
+ | Steps for adjusting MET2: | ||
+ | |||
+ | - Looking at the met signal while the cart is at the back. | ||
+ | - Peak so that the beam is aligned as well as possible. Does not need to be perfect but not loose. | ||
+ | - All beams have a signal between 1-2 volts while at the back. Sometimes the signal strength can change for no apparent reasons. | ||
+ | - Using steps of 50, try moving 3 times in one direction. After each step, wait 5 seconds or so for things to update. If nothing then try the other way. | ||
+ | - Return to starting position. | ||
+ | - Repeat for the other axis. | ||

+ | |||
+ | To minimize heat sources in the lab, the power for the apwheels is turned off. If you need to use aperture wheels during the night, the operator will need to plug the power into the outlet next to the metrology table (see photo below). If there are any communication issues after plugging in the power, try restarting the server using bootlaunch on ctrscrut. It's probably a good idea to home the apwheels after turning on the power. | ||
