Cable and Push-Button E-Stop Assembly

Cable-Operated Switch

This switch is a cable-operated and push-button emergency-stop device. At the same time it is used to provide an awareness barrier on exposed machinery, such as conveyors.

This switch enables this system to accommodate cable spans up to 248 feet (75 m).

The switch has a unique cam operation of the contact mechanism to give rapid, positive operation of the contacts. This mechanism also provides a failure to the safe condition if the cable goes slack or is cut, but is immune to nuisance tripping due to machine vibration. Should the cable be pulled, the contacts are opened, isolating machine power, and the latch engages. The machine cannot restart until the hazard has been corrected and the switch is reset. The switch is reset by turning the blue reset dial from the off position to the run position. This switch also incorporates a cable-tension indicator. This indicator assists in installation and maintenance of the switch. A red mushroom-head emergency-stop button is provided on each switch. Optionally available is an indicator light as shown.

Application Diagram

A cable tension kit, which includes thimbles, cable clamps and a turnbuckle, must be used with this switch. This kit includes the components to properly tension the cable. When installing this switch on cable runs over 12 feet, one switch should be installed at both ends of the cable. The cables should be supported by eye bolts every 6 1/2 to 10 feet (2 to 3 m) along its length. They should also be used about one foot from each switch to ensure that all emergency-pull movement is transmitted to both units in a linear fashion. If this assembly is to go around a corner, a free-moving pulley should be used. Please consult the factory if this is required.
