Updated Control Unit

With Micro Tools becoming the norm in many industries rather than the exception, Allora International has found an increasing need for tool monitoring capable of reliably detecting these extremely delicate tools.

When the SCU-100 Sensor Control Unit and TCU-250 Teach Control Unit were originally designed, they were very capable of monitoring small tools. With the addition of a CFR-300, it is possible to re-purpose an older SCU-100 Sensor Control Unit or TCU-250 Teach Control Unit for Micro Tool detection; however, this requires adding another component to the system.

With that in mind, Allora International revised the SCU-100 Sensor Control Unit and TCU-250 Teach Control Unit to include built-in Micro Tool monitoring capability. These updated Control Units are flexible enough to delicately monitor Micro Tools, yet fast enough to keep up with the latest high speed machines. The key to this flexibility is the addition of two new rotary dip-switches which allow for 15 different Cycle Time and 15 different Contact Force settings. These switches replace the three TIME dip-switches and the one HI/LO dip-switch found in previous revisions.

Another feature that has been added to the revised SCU-100 Sensor Control Unit and TCU-250 Teach Control Unit is a separate System Fault LED. With previous Control Units, a simultaneous Ok and Fault LED illumination indicated a System Fault. The revised SCU-100 Sensor Control Unit and TCU-250 Teach Control Unit have a separate red LED which flashes to indicate a System Fault. The separation of this function greatly simplifies troubleshooting.

All other features of the SCU-100 Sensor Control Unit and TCU-250 Teach Control Unit remain intact - as does the enclosure and all wiring/pin-outs. Furthermore, the revised the SCU-100 Sensor Control Unit and TCU-250 Teach Control Unit are fully retrofittable with previous PCS-100 and PCS-250 Positive Contact Sensors, meaning no new hardware (Sensor/Mounting/Cable) is necessary to take advantage of these new features.

As with previous revisions, Allora International ships each SCU-100 Sensor Control Unit and TCU-250 Teach Control Unit with factory default settings which are appropriate for the vast majority of applications. As a result, if Micro Tool detection is not required you likely can use the Control Unit right out of the box, without changing or adjusting anything. The flexibility of the newly increased number of Cycle Time and Contact Force adjustments, means that should the application change, the capability will already be built-in and easy to configure.
