TAC-7X
MANUAL
NOTE
NOTE
In proper operating order, the Transfer Arm will never
retract with a contact present in the Transfer Tip.
This feature prevents the possibility of dropping a
contact into a already loaded transfer tip.
When the Transfer Arm reaches the vertical position, a limit switch (LS-
1) is engaged and the following events occur:
-Limit Switch sensor (S-2) is turned on
-High pressure is supplied to Slide Cylinder, allowing it to stay
in the full extended position.
-V-3 is deactivated closing funnels
-Escapement Cylinder (EC-1) is activated, allowing a
contact to be advanced from the track assembly to the
drop tube.
If the contact exits the Drop Tube and seats properly in the Transfer Tip,
adequate vacuum will exist to switch on the Transfer Tip Sensor, (S-6).
Supply for Vacuum Sensor switch is provided by Vacuum Generator
(VG-1).
If a contact does not seat properly in the Transfer Tip, the
cycle will terminate until reset.
With S-6 turned on again, V-2 is turned off, allowing the Transfer Arm to
return to the "ready to crimp" position.
The TAC is now ready to have another properly stripped conductor inserted
in the wire funnel and commence another crimping cycle.
