Tracking stuck ON

Wednesday, June 1, 2016 12:45 PM

Problem(s) Encountered:

The ''track'' switch on the front panel does not seem to work.  Whenever the ''drives'' switch is on, the telescope tracks no matter what position the track switch is set to.  So there was no impact on observing, but when parking the telescope at the zenith it is necessary to turn off the drives switch in order to suspend tracking.


Solutions:

This has been seen previously as well.  It is a state that hangs in the TCS PC.  The solution is to reboot the TCS computer (making sure to note the focus position, reset the track rate to 15.06 and reset telescope encoders by the tilt sensors).  

Computer reboot and everything should be ready to go again tonight.
