Checking it out. Mon May 29 16:45:37 GMT 2000 PICS End Patrol **PICS PROBLEM**: Mon May 29 16:46:03 GMT 2000 Stopping PICS. Repaired gearbox is a lot quieter but sems to be turning a lot slower than I recall. Patrol Optics status is timing out a lot and stopping at the wrong stations, occasionally stopping between stations. Checking out movement using handheld terminal upstairs. Mon May 29 18:13:42 GMT 2000 PICS Start Patrol **PICS PROBLEM**: Mon May 29 18:14:43 GMT 2000 Fixed occulting wheel. There was too much grease in the gearbox. Motor was turning very slow, overloading supply. Wheel was timing out. Cleaned out some of the grease and thinned it a little with WD-40. Motor sped up significantly, power supply not strained, and mechanism drive no longer timing out. Now having problem with the objective wheel not finding the correct position and timing out. Checking that out. **PICS PROBLEM**: Mon May 29 19:02:09 GMT 2000 Timing the objective wheel is proving to be very difficult due to locations of set screws. MCC may need a reset, handheld terminal indicating that status may be aligned but the driver is still timing out. WEATHER COMMENT: Mon May 29 19:05:04 GMT 2000 In cirrus.

The encoder must be aligned 180 degrees out of phase--maybe to make the setscrew more accessible-- and the program has been modified to correct for the anomaly. COMMENT: Mon May 29 19:27:04 GMT 2000 reconfiguring dome shutter.

Now PICS is working.

Stopping MKIV and resetting KCC. WEATHER COMMENT: Mon May 29 20:31:02 GMT 2000 Cirrus clear for now. Mon May 29 20:31:37 GMT 2000 MKIV Start Patrol **PICS PROBLEM**: Mon May 29 20:32:00 GMT 2000 Occulting wheel motor sounds OK. I hear some clunking in the Geneva, still.
