2. Operation
All functions of the TAC are initiated, terminated, controlled and
operated both pneumatically and electrically. After the TAC has
been set up properly, only two functions are operator-adjustable:
The amplitude of the feeder-bowl vibrations and, if a feature of this
particular TAC, the selected "G" dimension. All other functions are
machine controlled.
Interlocks are provided in the Control System to prevent any out-of
sequence event from occurring. System design is such that if the indenter
does not crimp completely, the device will not permit that particular
contact from exiting the crimper without performing a reset. If a contact
does not seat properly in the transfer tip the equipment will disengage. All
events occur automatically, except the insertion and extraction of the
conductor, which is operator performed.
The crimp cycle initiation occurs when a properly stripped conductor is
inserted into the contact to be crimped, and depressed. Depressing the
contact with the conductor inserted triggers the TAC; when the crimp is
completed the operator withdraws the conductor with the contact now
attached; the TAC re-cycles and places another contact in proper position;
the operator inserts another properly stripped wire into the contact,
depresses it slightly, and the cycle repeats.
Figure 1-2 shows the funnel through which the operator inserts the
conductor into the contact. In most cases the arbor cover plate is
chemically treated a dull black color in order that operators may more
easily recognize a flayed or skewed conductor strand prior to insertion.
TAC's equipped with funnels eliminate eye-hand coordination fatigue as
the operator need not visually affirm each conductor strand is inserted into
the contact. The funnel design assures all conductor strands, even if not
twisted together, will enter the contact so long as they are not bent back
when inserted into the funnel. TAC's eliminate all eye-hand-foot
coordination fatigue and timing techniques, as there are no foot-switches.
