cannot be produced without overloading the machine.
9.1.2 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) Observe that a reading appears on the tonnage displays after
the first machine stroke that produced a part.
3) An overload on any channel will be indicated by a flashing
light and/or flashing tonnage reading and will prevent another
stroke. The supervisor should be called and the condition
that caused the overload cleared before pushing the CLEAR key
on the System 1100 and proceeding with production.
4) If the press will not stroke and an error occurs (indicated by
a flashing STOP CIRCUIT indicator light) call the supervisor.
9.2 Comprehensive Load Monitoring
Although monitoring only for machine overload provides great
benefits in machine maintenance and repair costs, using the System
1100 in a more comprehensive load monitoring scheme that
establishes standards and monitors production tonnages more closely
can greatly expand benefits to the user. Both machine and tooling
life can be extended, energy can be conserved, fewer scrap parts
generated, and part quality can be made more consistent by using
the System 1100 to determine and optimize tooling location and
required tonnage in die setting; and by selecting high, low, and
reverse setpoint limits so that changes in tonnage greater than
those due to normal variations in the production process will trip
an alarm and stop the machine from cycling.
A comprehensive load monitoring program requires more knowledge and
interaction with the System 1100 by die setters and operators than
a simple machine overload monitoring program. The following
procedures and information can be useful in establishing a
comprehensive load monitoring program. Of course, the user may
choose to modify or add to the described procedures to suit his
particular needs.
