The Near, Software, and Hardware rows display the current status of each limit -- either "clear" or "TRIPPED". "Near" limits are simply warnings that a particular limit is being approached, and do not affect telescope motion.

A tripped "Software" limit disables telescope tracking and autodome. The telescope can be driven out of a software limit by entering a new (and acceptable) telescope position in the Main Window and pushing the "Move to Target" button, or by manually slewing out of the limit.

"Hardware" limits are rarely tripped, as the software limits generally disables motion before the hardware limit is reached. However, it is possible in some cases for the telescope to coast past a software limit and trip a hardware limit. When this occurs, it is necessary to manually slew the telescope out of the limit using the paddle on the dome floor.

Note that there is no hardware zenith limit, and that the "near" and "software" zenith limits simply warn that the telescope is approaching or within the zone around zenith where the telescope is partly occulted by the dome. Telescope motion is not affected.

Limit status, zenith warnings, and approximate percentage of zenith occultation are displayed in both the Direct Imaging Main Window and the Spectroscopy Main Window.
