PROJECT: Rollover 3B, 4B Equipment Upgrade

CLIENT CHALLENGE:

The client was burdened with antiquated hard wired relay control systems. Each one used 120 digital inputs and
outputs to control rotating heavy steel wheels.

TRI-STAR AUTOMATION SOLUTION:

The extreme weight of the massive steel wheels being controlled, and the subsequent high inertia they exerted on the
drive motors, required us to specify and implement new variable frequency drives with dynamic braking to increase
both speed and braking abilities. Each hard wired relay control system was replaced with a fully integrated PLC system
complete with HMI screen display with set points alarms and diagnostics.

                    To minimize impact on
                    production, the entire changeover
                    was completed in a single
                    weekend through the utilization
                    of around the clock shifts.
