Subject: SecDesMountOutOfRange Error
    It looks like whenever the telescope is sent to zenith (instrument
change), the secondary can't put the D actuator where it wants to.
This isn't a problem if it only happens at an altitude of 90, but
could be if it happens at 85.
    During the afternoon check, see if the error occurs for elevations
less than 90.  Some sequence like 80, 85, 87, 88, 89 should fairly
quickly determine where the actuator position hits the limit.  It
might be good to try both spectro and imager instrument settings.
However it should be fairly insensitive to that change as the
offending actuator is transverse ( it would only be an issue if the
transverse limits were a function of axial position ).

Below are TCC log excerpts showing that each time the error appears
the telescope is at instrument change.
