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. If the wrong
transfer tip is installed, the system will produce error message. 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.
