3.2. Tooling Adjustment
Two setscrews are provided at each side of the ram
head (at the top of the module) for adjustment
purposes. The front setscrews allow adjustment of
the hexagonal crimper. The rear setscrews allow
adjustment of the contact inserter and secondary
strain relief. If the contacts have the proper crimp
height, the secondary strain relief will have the proper
height, as well (by construction).
If adjustment is required to obtain proper crimp
height, refer to Figure 3 and the applicable application
specification, and proceed as follows:

5. Check that the two single–wire terminations on
the limit switch to the left of the tester cable
(viewing from the rear of the module) are firmly
connected to the limit switch at the top–most and
bottom–most terminals (normally–closed position).
Verify that the green wire of the tester cable is
connected to the terminator and to a suitable
ground on an AC outlet. Refer to Figure 2.
6. Position the module so that the T–slot at the top
will slide onto the arm of the terminator so that the
module rests on the base plate of the terminator.
Tighten the screws at the bottom front of the
module, securing the module to the base plate.
7. Re–connect the air supply to the terminator
(regulated air supply range of 551 to 689 kPa
[80 to 100 psi] at 0.47 liters/sec [1.0 scfm]).
8. Re–install the plastic guard onto the module.
Run samples according to 409–10010 to inspect
the crimp height of each modular plug. If
necessary adjust the crimp height as described in
Paragraph 3.1.
NOTE
1. Remove the module from the terminator by
reversing the installation instructions provided in
Paragraph 3.1.
2. Place the module on a horizontal, flat surface.
3. Check the clearance between the hexagonal
crimper legs and the hexagonal anvil with a piece
of thin paper. Clearance must be within the
dimensions given in Figure 3. If adjustment is
required, slightly loosen the the socket head cap
screws at the front of the ram and the front locking
setscrews at the front of the ram head. Then rotate
the front setscrews to adjust the hexagonal
crimper.

Normally the module is adjusted prior to
shipment, and little or no adjustment will be
required by the customer. However, if wearable
parts are replaced, a small amount of adjustment
may be required.

4. If the contact crimp height is still not correct,
loosen the rear locking setscrews at the rear of the
ram head. Make sure that the rear locking
setscrews are loosened. Rotate the rear setscrews
to adjust the crimp height (simultaneously adjusting
the secondary strain relief). Rotate the screws
clockwise to move the contact inserter downward.
NOTE
5. After adjustment has been performed, push the
three parts at each side of the ram to the
upper–most position, and tighten the socket head
cap screws at the front of the ram. Re–position the
ram on the module. Then re–install the module on
the terminator as described in Paragraph 3.1.
6. If the hexagonal anvil has been moved or
replaced, it may require some “in–out” adjustment
as follows:

a. Remove the ram.
b. Loosen the button head cap screw on the
hexagonal anvil. See Figure 4.
A 360-degree rotation of the front setscrews
makes a difference of approximately 0.8 [.032].
A 360-degree rotation of the rear setscrews
makes a difference of approximately 0.8 [.032].
