Table 6-2. Setpoint Faults: Possible Causes
Setpoint Fault
Type
Possible Cause(s)
Repeatability Change in the die due to:
Slug stacking
Misfeed
End of stock
Broken punch
Change in material thickness or hardness
High
Material feed problems
Double parts in the die
Tool wear
Loss of lubrication
For presses with column-mounted strain links, high tonnage readings could
indicate galled leader pins or bushings.
If the press is running without tooling, high tonnage readings may
indicate improper lubrication or loss of lubrication in the gibbs or bearings.
Low
End of stock
Broken punch
Reverse Refer to Table 6-1.
120% of Press
Capacity
Refer to Table 6-1. Also check the following:
Foreign objects (e.g., wrench) in the die
Electrical noise in the strain link cables, which can cause false signals
If only one input is overloaded, try moving the tooling/die
away from that input to distribute the load more evenly.
Offset Errors
AutoSetPAC displays an offset error when one or more strain links transmit a signal that is either too
high or too low for the load analyzer to interpret accurately. Offset errors occur when a strain link
loosens, is damaged, or otherwise fails.
To correct the problem:
•
Check wiring of the strain link(s) on the affected channel(s). Rewire if necessary.
•
Check mounting of the strain link. If the strain link has loosened, remount the strain link.
•
If neither of these solutions fixes the problem, the strain link may be damaged and should be
replaced.
If you remount or replace a strain link, you must rezero the strain link (refer to
Zeroing Strain Links
,
page 73). When replacing a strain link, you do not have to recalibrate AutoSetPAC unless you move
the strain link to a different location.
