In the APCC documentation the following warning appears frequently:
"The Meridian Limits, are primarily tracking limits in the west,
and counterweight-up slewing guides for APCC's advanced
slew logic in the east. They will NOT prevent you from
slewing into your pier with an incorrect slew, or from running
into the pier with direction buttons."
So I get that using the direction buttons can run the telescope into the pier. However, if the meridian limits are set up correctly, what else constitutes an "incorrect" slew?
