Action : Cut the cooling pipes and have the electronics inserting a PT100 in a pipe in each motor. Action Log : 2/6/03 2:58:18 PM gandreon Action on hold since it appears that these motors may require some cooling. Responsible : Engineering Dep.(Mechanics) Status : New Deadline : Deadline Status : Not Assigned ________________________________________________________________________________ Telescope : ESO NTT Create-date : 12/19/02 3:50:03 PM Problem Short Description : Temperature in ALT motors needs to be monitored. Action : Please provide the reading of th temperature of the four motors in the same panel used for the AZ ones. Action Log : 3/21/03 9:39:28 AM jguzman Please, provide more input about hardware implementation. For AZ motors, there were installed PT-100 inside them in order to read the temperatures from a PULPO unit, which is connected to LCU via RS-232. Please ask electronics about feasibility to install PT-100 inside the motors and include them in the discussion about implementation of the action point. 3/27/03 2:58:33 PM gandreon Subject to feasibility of previous item. 4/7/03 6:23:34 PM gandreon GIH: A serious concerns regarding the PULPO capacity to read the temperatures was presented. Actually PULPOs can read 6 sensors, 4 are in use with the Azimuth motors, so if one day this is required for the ALT motors we are short in number of sensor readings. On the other hand there are no spare PULPOs and it is urgently need one for FEROS. If this is the case it is recomended to change the temperature reading system to another than PULPO and to leave this one for other purposes. 4/8/03 3:42:11 PM gandreon The possibility of using the VLT Temperature Monitoring System shall be investigated. 4/17/03 10:07:42 AM fgutierr VLT development platforms supports several TYPES OF hardware devices to read temperatures. For few points the ADAM solution is appropiated (2*4 channels + Spare ~US$ 2196). For 20 points the Aligent Data aquisition seems more appopiated. 4/22/03 2:33:26 PM gandreon List of temperatures to be monitored and their location is needed to proceed.

Action : Insulate dewar. Troubleshoot the problem. Action Log : 1/9/03 2:17:18 PM gandreon Free time to work on this CCD is required for this and the O ring change. 1/30/03 2:27:14 PM gandreon A insulating flange has to be prepared by mechanics. 2/20/03 2:00:44 PM gandreon Dewar is now insulated but fringes are still present. Under monitoring by E. Pompei. 2/27/03 2:05:06 PM gandreon Problem will be tackled after the dewar replacement. 3/27/03 2:53:13 PM gandreon Some improvements have been detected after intervention with ground connections. To be continued once the dewar is changed. 4/7/03 6:24:51 PM gandreon GIH: EPO informed that actually the situation is critical, because on top of the noisy behaviour it is unstable. An urgent action is required. 4/15/03 2:28:50 PM gandreon Interference source traced to camera and shutter control. They are being insulated to eliminate the interference. 5/6/03 3:55:13 PM gandreon This action proved to be counterproductive ad it will be reversed. Responsible : Engineering Dep.(Instrum.)

Considering that the whole DSS-1 is ~85Gb, it is now feasible to have it entirely on-line locally on one disk. The work requested can be split in several consecutive phases: - install a local copy of DSS-1 with a web-tool similar to http://archive.eso.org/dss/dss - provide a configuration to point skycat to that local server - investigate the possibility to have DSS-2 on-line locally (volume eqv to 70DVDs). Action Log : 10/31/02 2:05:02 PM gandreon Since meli is not under our control a PC with Linux will be purchased and installed. DSS-1 will be first installed but the system will be configured to handle DSS-2. 11/21/02 2:57:01 PM gandreon Computer order has been placed. 12/19/02 4:06:07 PM gandreon Discs order prepared. 1/9/03 2:21:03 PM gandreon PC arrived.
