SLIM - Resolver Based Signature Force Monitor
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.
4-Channel Signature with Critical Curve Monitoring and Enveloping
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
Each of the alarm types listed above can be set as a top or immediate stop within the SLIM. Each channel (corner)
can be enabled or disabled as well (with a master password). The SLIM also provides basic statistics such as:
- Highest Load
- Lowest Load
- Last Alarm
- Last High Alarm
- Last Low Alarm
- Number of Capacity Alarms
- Number of CCM Alarms
- Number of High Alarms
- Number of Low Alarms
- Number of Reverse Alarms
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 starndard
text files.
The SLIM unit also provides a starndard 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. To view more about our networking
packages, click here.
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
