| Model TB-2 Start Bar |
| Series Description: The Nolatron TB-2 machine start bar is a complete OSHA compliant ergonomic two hand starting system. It increases productivity while operator fatigue and stress are decreased. It includes a cast aluminum enclosure, guarded hand sensors and an anti-defeat (anti-tie-down) control with front panel indicator lights. When properly installed, the TB-2 start bar meets OSHA requirements of section 1910.217(6) which covers two-hand controls. |
| Series Operation: The start bars internal anti-defeat safety control performs a test prior to each machine cycle. This is done to ensure that the output relays and electronic circuits are functioning properly. The Ready light on the front of the bar will then turn on indicating that the bar is ready to be started. You must concurrently touch both hand senors in order to start the machine cycle. The Output light will then turn on, indicating that the load has energized. If either start sensor is continuously energized (tied down), another machine cycle cannot be started. Momentary Output To begin a machine cycle, both hand sensors must be touched within a window of time.* The load will then energize as long as the hand sensors are held or the optional Reset switch is momentarily opened. The Reset switch must be closed in order for the bar to be ready for the next machine cycle.* This time is factory set at .5 seconds and is adjustable. Maintained Output An optional Hold switch can be wired into the start bar to provide a maintained output. When the Hold switch is closed, the load will stay energized even after the start switches are released. The Hold switch must not close until the machine passes the pinch-point, and it should remain closed for the rest of the machine cycle.If the optional Reset switch is opened at any point during the machine cycle, the outputs will de-energize and the control will reset. Both start switches must be released and the Reset switch must be closed before another machine cycle can be started. |
