NEW TB-2SRQD Quick Disconnect
Programmable Anti-Tiedown Start Bar
The TB-2SRQD 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, hand sensors and an anti-tiedown control with front panel indicator lights. New feature on this model, our hand sensors can now be installed, up to 12’, away from enclosure. This provides greater flexibility in confined workspaces. When properly installed, the TB-2SRQD meets OSHA requirements covering two-hand controls.
The start bar has a microprocessor and multiple modes of operation that can be programmed to fit various applications. It counts and displays machine cycles on the enclosure display.
Anti-tiedown – requires an operator to have both hands on start switches in order to start machine operation. This minimizes the possibility of the operator starting the machine while his hand is in the work area.
Control Reliability – designed to meet the OSHA classification of “control reliability” as defined in Sec. 1910.217(b)(13).
Redundant Output Contacts – uses double positive guided output relays. Each relay is checked for proper status prior to beginning a machine cycle.
Ergonomic – the angle of the hand sensors coincides with the natural movement of the hands and require no pressure to operate.
Safety – guarded hand switches allows actuation only from the side towards the machine operator.
Operation modes – multiple modes defined by setting options in the setup menu. These include Momentary Output, Maintained Output, Timed Output, Maintained Timed Output, Delayed Timed Output, Maintained Delayed Timed Output and Part-in-Place Mode.
