Hi! Cliff.
Thanks for the message I'll investigate further, however the manufacturers
did lead me to believe that when the motor reaches the end stop it then will
only motor back with the reversed current. This seemed to me to indicate
that the stop was a limiting switch and the problem was at the motor. I have
a panel mounted trim switch AND a stick top switch with an automatic
changeover relay deck, both supplied by the motor suppliers.... Menzimer.
Regards
Bob H G-PTAG
