The SLIM is a resolver-based tonnage signature interface module that provides force measurement and signature analysis for critical force applications up to 800 spm.

The SLIM unit is designed and configurable for single action, double action and transfer presses.

Signature analysis can be used in determining the amount of force exerted throughout the press stroke. This can be especially useful in determining if the amount of stress on the press is happening too early in the stroke. It is important to know what tonnage is being developed and where in the press stroke it occurs.

Every press manufacturer provides a press-rated tonnage curve and motion diagram, which can be uploaded into our SLIM monitor. This curve is then plotted against the actual tonnage signature and can be viewed through the user interface software, SlimWare.

The SLIM's onboard memory allows for operators/setup personnel to retrieve the last 25 signatures. Along with signatures, setpoints can be saved and loaded with each job. These setpoints include:

  • Capacity
  • CCM (Critical Curve Monitoring)
  • High Setpoint
  • Low Setpoint
  • High Enveloping (5-Zones)
  • Low Enveloping (5-Zones)
  • Reverse Setpoint

The SLIM can also interface with a wide variety of equipment ranging from the most sophisticated Allen-Bradley & Siemens programmable logic controllers (PLCs) through the use of OPC server/client tags, to standard personal computers (PCs) through the use of standard text files.

The SLIM unit also provides a standard option of data-logging. This option saves any alarm, setpoint or configuration change to a text file along with a timestamp and user ID. This can provide a detailed history of any alarms or changes made to the SLIM unit.

For a more detailed alarm history, our PressNet and MaxNet networking packages allow for detailed reporting by time, press, user and types of alarms.

The SLIM unit comes standard with the user interface software, SlimWare. This software can be installed on any desktop/industrial PC with the following operating systems:

  • Microsoft Windows 2000
  • Microsoft Windows XP
  • Microsoft Windows XP Embedded
  • Microsoft Windows Vista
  • Microsoft Windows 7
