Simplifying machine actuation

April 2008 Motion Control & Drives

Banner Engineering has introduced the DUO-TOUCH run bar with self checking touch buttons (STBs) for two-hand control machine actuation. The run bar easily interfaces with DUO-TOUCH SG (second generation) two-hand control modules, SC22-3 safety controllers or other type IIIC control systems to provide convenient and reliable operation. The run bar minimises the possibility of accidental actuation and its ergonomic design reduces hand, wrist and arm stresses associated with repeated switch operation. Two preinstalled STB touch buttons are included to aid set-up and installation.

Packaging is of robust 13-gauge cold-rolled steel construction designed for maximum ergonomics and safety. The self-checking microcontroller-based photoelectric STBs minimise the risk of spurious machine actuation. The buttons are immune to ambient light and EMI interference and high excess gain is provided to cut through heavy contamination. Bright status LEDs indicate power, output and fault conditions. For added convenience and installation flexibility, models with an integrated emergency stop button along with a variety of accessory brackets and telescoping floor-mounted stands are available.

“The new DUO-TOUCH run bar is designed to solve the ergonomic problems associated with mechanical pushbuttons, while simplifying installation,” said Mike Carlson, technical manager for Banner’s safety products. “The system contains two preinstalled STB self-checking touch buttons which require no physical pressure to activate, protecting workers from hand, wrist and arm injuries resulting from stressful manual operation,” Carlson adds.

Designed to comply with ANSI B11.19 and ISO 13851 (EN 574) Type IIIC two-hand control requirements, makes the product a rugged and reliable solution for general initiation of a cycle on a variety of machines, including:

* Punch and power presses.

* Cutting and forming machines.

* Riveting and swaging machines.

* Heat staking machines.

* Table-top robots.

Several features of the run bar make it particularly easy to set up and use, including:

* Minimal risk of accidental machine actuation.

* Convenient and economical safeguards for control system interfaces.

* Ergonomic design for reduced hand, wrist and arm stress.

* Integrated emergency stop button.

* Optional mounting brackets and stands.
