Home switch mount was again bent out of shape. I took it apart and straightened the mount post. Took microswitch apart and checked it out. NC and NO were actuating OK. Reassembled the switch and mount and adjusted the actuator. Dome is still running in the wrong direction to home itself. Checking further. ___end___ WEATHER COMMENT: Sun Oct 28 19:43:04 GMT 2007 In scattered cirrus ___end___ **PSPT PROBLEM**: Sun Oct 28 19:56:36 GMT 2007 There are two mechanical relays in the dome rotator box. Top one is for RUN on/off. Bottom one is for DIRECTION cw/ccw. RUN turns on each time dome is rotated. DIR turns on when CCW (dome goto decreasing number) is requested. DIR does not actuate when CW (dome goto increasing number) is requested. Mechanical relays function normally when manual switch is actuated, both CW and CCW. Computer control bypasses the manual switch and goes thru a pair (L & R--RUN and DIR) of SSRs. Checked the control voltages to each SSR and found there wa no change in voltage to the DIR SSR when CCW was requested--there should be for CCW and there shouldn't be for CW. Disassembled Jones connector to the box that provides the DIR control from the computer and found the red wire to pin 2 broken. (Pins 1 & 2 are DIR, pins 3 & 4 are RUN). Resoldered the wire, reassembled connector and tested dome rotator. Rotation in both directions now work correctly. Dome rotator still has a problem of jumping the track near the HOME azimuth. This causes the dome to rotate to an incorrect azimuth after homing itself. Encoder counts the requested steps but the dome doesn't actually rotate that number of steps due to the skipping. Attempting to adjust that problem. ___end___ **PSPT PROBLEM**: Sun Oct 28 21:06:38 GMT 2007 Marked off track sectors where dome rotator motor/drive was jumping. Lifted the track a little with crowbar in those sectors. Tested--drive ran smoothely over the sectors. Reassembled everything that was taken apart earlier. ___end___ PSPT COMMENT: Sun Oct 28 21:09:00 GMT 2007 Starting up --- everybody is behaving! ___end___ PSPT COMMENT: Sun Oct 28 21:10:52 GMT 2007 Observing.
