Honeywell AutoSet 1500 User Manual page 52

A nuisance stop occurs when setpoints are so tight that normal variations in tonnage
cause AutoSet Plus to shutdown the press. Our goal is to create setpoints just high
enough, yet tight enough so that nuisance stops will not occur.
A tonnage fault occurs when the tonnage has fluctuated enough to exceed the high
setpoints being used by the load monitor. A fault may be a number of die
malfunctions. To correct the problem, carefully inspect the die area. For your
information, the different tonnage faults are discussed in detail in Chapter 5 .
If the press stopped due to a real fault, do not continue until you have completely
corrected the problem! Failure to do so may result in damage to the press and tooling.
If AutoSet did not shut down the press in Step 1:
If AutoSet shut down the press in Step 1:
IMPORTANT: If you have to keep moving the dial up and AutoSet still keeps
shutting down the press, there may a problem with the die or your setup. Check for
other causes of press stoppage besides nuisance stops.

WARNING
A. Click the dial down to 3 (10%). Start the press. (For continuous
stroke only: if your press produces erratic tonnage at start-up,
reset again after tonnage stabilizes).
B. Run the press beyond the sample period to see if a nuisance stop
occurs. If so, go to step D. If not, set the dial to 2 and run the press.
C. If a nuisance stop occurs at 2, go to Step D. If none occurs, go
down to 1 and run the press. If no nuisance stop occurs now, this
is the right setting for the job. (Note: A "1" setting is the lowest
you can go. A zero setting will not create setpoints).
D. Complete this step only if a nuisance stop occurred in Step B or C. If
so, make sure the press did not stop for some other reason. Then click
the dial up one (from 2 back to 3, for instance). Run the press. If no
nuisance stop occurs now, this is the right setting for the job.
A. First make sure the press stopped because setpoints were too
low. Check for a stuck part, load imbalance, a misfeed, or any
other cause besides a nuisance stop.
B. When you are satisfied the press stopped because setpoints were too
low (a nuisance stop), click the selector up to 5 (20%); then run the
press again. (For continuous stroke only: If your press produces
erratic tonnage at start-up, reset again after tonnage stabilizes).
C. Check for a nuisance stop. If a nuisance stop does not occur now,
this is the right setting for the job.
D. If a nuisance stop still occurs, click the selector up to 6. Run the
press again. Check for a nuisance stop. Continue moving the dial
to a higher percentage until no nuisance stop occurs. This is the
right setting for the job.
