The reason that the TV Camera's pan motor
would not turn off was that motor relay for "Pan
Right" was stuck closed. Although the relays that
are used for the pan and tilt motors probably have
adequate contact rating for the continuous motor
current (0.25 Amp), they are really too small to handle
the several-amp turn-on surge — especially when
this surge occurs often, as when the motors are
hunting (in a servo loop). The pan motors work all right
now because the wires on the pan-right relay have
been moved over to its unused contacts. If a similar
failure occurs again, a new relay control box should
be built using (six) 5 or 10 amp relays.
