When AutoSet displays a high setpoints fault
When the actual "LOAD" tonnage exceeds the "SETPOINT" tonnage on one or both
inputs, an overload condition exists. AutoSet will open the output relay. The "LOAD"
display for the overloaded input will flash, and "HI" will flash on the one or both of the
setpoints displays, depending upon which strain links affected. See Figure 5-1.

Check to see why AutoSet stopped the press. Is it due to a problem in the die, such as
stuck part, variation in shut height, drastic change in material thickness, etc.? If so,
correct the problem immediately.
Or is it due to a nuisance stop because the high setpoints are too tight? Then see
"Creating setpoints for the job" to change the high tolerance percent.
AutoSet is cleared by holding the reset button down for less than two seconds. The
displays will stop flashing, and the overload values remain on the "LOAD" displays until
the next stroke, or until power has been turned off.
Remember that holding the reset button for more than two seconds signals AutoSet to
recalculate setpoints. Therefore, when clearing an overload condition, press and release
the button quickly (less than two seconds). This will clear the overload, but
will not
signal AutoSet to recalculate setpoints.
Note:
Data Instruments recommends you connect AutoSet to the top stop circuit (not E-
Stop circuit) of the press.This is so the press will not stick on bottom if an
overload occurs.
Remember that top stop circuits are active only in continuous (automatic)
operations on most press controls. If overload protection is required during inch
or single stroke mode, you may have to install an additional relay so AutoSet will
stop the press.
