Overview
The Model RSB Cable-Operated Safety Stop Control, like the Model RS Pull Cord Safety Stop Switch, provides both immediate machinery shutdown and sends a signal to an alarm when its cable is pulled due to an operational issue or by an endangered worker. Its advantage over the Model RS is that it also incorporates a built-in broken cable detector. The RSB Safety Stop Switch is ANSI-recommended for the safe operation of conveyors, production lines, elevator equipment, assembly lines, material handling systems, cranes, and similar equipment where systems, machinery, or employee protection is required. Note: most states require this type of safety control on conveyors.
NEED TO KNOW
The RSB Control is designed so that a maximum of 100' (30m) of cable can be used on each side of the switch. A single control, therefore, covers a maximum of 200' of conveyor belt or other machinery. The RSB Control can be actuated via a cable pull from either direction, in other words, the switch is “double-ended”. Pull cable is required on EACH side of RSB unit (+/- 5 ft). The Model RSB has extension springs, attached to opposite ends of the pull cable, which maintain the cable under constant tension. The RSB Safety Control is mounted centrally between the end springs so that temperature changes, which cause cable length changes, are canceled out. The application’s electrical characteristics determine the type of microswitches to be specified in the unit. Environmental considerations determine if the RSB Switch needs to be explosion-proof or requires an available epoxy coating.
Our galvanized aircraft cable with either vinyl or nylon coating should be used with the Control to assure proper actuation with no stretching. The cable should be supported by eyebolts every 8 to 10' (3m). These supports ensure that the weight of the cable alone will not actuate the Control. An optional red incandescent light (standard or LED) is available for dark or remote locations.
An optional red incandescent light (standard or LED) is available to aid in identification of actuated units.
For ease of installation, we offer the RS-K Mount Kit that includes all components and correct quantities for the proper installation of one RSB Control.
