Section 1 Introduction<br />

The 5100-10 <strong>Automatic</strong> Setup Module allows the <strong>OmniLink</strong> <strong>II</strong> <strong>Press</strong> <strong>Automation</strong> <strong>Control</strong> to<br />

automatically adjust press shut height, counterbalance air pressure and cushion air pressure when<br />

jobs are recalled from memory. It consists of a base 5100-10 microprocessor board that<br />

connects to the <strong>OmniLink</strong> <strong>II</strong> <strong>Press</strong> <strong>Automation</strong> <strong>Control</strong> system, and additional boards that may<br />

be mounted on the base board to provide pressure or shut height adjustment functions. Each<br />

5100-10 module can control; one slide adjust system and two air systems, four air systems, or<br />

two slide adjust systems. Up to four 5000-10 <strong>Automatic</strong> Setup Modules can be connected to an<br />

<strong>OmniLink</strong> <strong>II</strong> <strong>Press</strong> <strong>Automation</strong> <strong>Control</strong> System.<br />

Section 1.1 Counterbalance <strong>Control</strong><br />

The proper setup of the air counterbalance system in a press is often thought of as a relatively<br />

unimportant detail. In fact, the counterbalance performs a very critical function. By countering<br />

the weight of the slide and its associated tooling a properly adjusted counterbalance:<br />

‚ Takes up bearing clearances before the die closes at the bottom of the stroke, reducing<br />

bearing load and impact.<br />

‚ Helps reduce gear tooth impact in geared machines by maintaining drive edge gear tooth<br />

contact in the press downstroke.<br />

‚ Decreases the downstroke stopping time of the press since less load is seen by the brake in<br />

the downstroke.<br />

‚ Enhances safety by reducing the possibility that the slide will free fall, if the brake is released<br />

and the clutch is not engaged.<br />

‚ Causes less total energy to be used by the press.<br />

‚ Increases drive motor life by reducing peak motor currents.<br />

None of the foregoing advantages will be realized if the counterbalance pressure is set too low.<br />

But a counterbalance pressure that is set too high is also detrimental to the press, causing<br />

excessive clutch wear and loss of flywheel energy in the downstroke before the dies contact<br />

material.<br />

By setting the pressure automatically when a job is recalled, the <strong>OmniLink</strong> <strong>II</strong> <strong>Press</strong> <strong>Automation</strong><br />

<strong>Control</strong> <strong>Automatic</strong> Setup module assures that the pressure is correct for the tooling used. This<br />

not only reduces machine maintenance, but also increases safety and speeds up job setup<br />

tremendously. In addition, the <strong>Automatic</strong> Setup module sets the correct pressure for each die,<br />

rather than an approximate pressure for a range of die weights from tables provided with<br />

manually adjustable counterbalance systems.<br />
