distribution can be use of different shims or parallels on
dies or different location of shims or parallels from setup to
setup.
If, when the TOTAL tonnage is adjusted to the initial
reference value recorded on the die, a correct part can't be
made, adjust the tonnage slowly upward till a correct part is
produced. Remember, differences in material thickness and
hardness can cause more or less tonnage to be required. A
TOTAL tonnage required to produce a correct part that is
significantly greater than the reference tonnage recorded on
the die may indicate die wear severe enough that die rework
should be scheduled.
Proceed to step four of this procedure after final die
location and tonnage have been set.

Note the tonnage readings on each channel of the System 1100
Tonnage Monitor after making a trial stroke under final setup
conditions. If the tonnages on each channel of the System
1100 fall approximately between the previously determined high
and low setpoint limits, then move the keyswitch from the
BYPASS position to the RUN position for production.
If the tonnage on one or more channel(s) is different than the
reference tonnage recorded on the die for that/those
channel(s), set the high and low setpoints for each channel at
about the same percentage above and below the actual tonnage
readings of each channel as the previously stored setpoints.
The System 1100 can do this automatically through the Auto
Setup function. The keyswitch should be returned to the RUN
position for production.
9.2.2 Sample Operator Instructions
1)
Each time power is first turned on to the machine, observe
that the System 1100 tonnage displays go to zero (0) before
attempting to cycle the machine.
2)
After the first machine stroke, observe that a reading appears
on the tonnage displays.
3)
In the event that a high or low alarm on one or more channels
of the System 1100 stops the machine and prevents another
stroke, the supervisor should be called and the condition that
