WARNING: Not a Safeguarding Device An Emergency Stop Device is not considered a safeguarding device because it requires an overt action by an individual to stop machine motion or hazards. A safeguarding device limits or eliminates an individual s exposure to a hazard without action by the individual or others. Because an individual must actuate the device for it to function, these devices do not fit the definition of a safeguarding device and cannot be substituted for required safeguarding. Refer to the relevant standards to determine those requirements. Overview Models RP-LS42F-xxLE are rope pull (cable pull) emergency stop switches in compact, limit switch style housings made of high impact thermoplast. When used with steel wire rope, they can provide continual access along the span for emergency stop actuation. Red PVC-covered 3 mm diameter wire rope is recommended (see Rope Pull Hardware on page 11). The rope pull system is the switch(es), the rope, supporting hardware, tensioning springs/hardware, and anchor points. When the rope is properly tensioned, the red arrows are centered in the tension indicator window, the safety contacts at terminals 21/22 and 41/42 are closed, and the monitoring contacts at terminals 13/14 and 33/34 are opened (see Tensioning the Rope). The safety contacts open when there is a cable-pull or cable-break situation, and remain open until the built-in reset button is manually reset (see Figure 2 on page 1). The safety contacts can be interfaced in either a single-channel or dual-channel method (see Hookup on page 7). Terminals 13/14 and 33/34 are for non-safety monitoring purposes only. Emergency Stop Considerations ANSI NFPA 79, ANSI B11.19, IEC/EN 60204-1, and ISO 13850 specify emergency stop requirements for rope (cable) pull installations, including the following: Be located where emergency shutdown is required Be continuously operable, easily visible, and readily accessible. Do not mute or bypass Provide constant tension of the rope or cable pull The rope or cable pull, as well as any flags or markers, must be colored RED The rope or cable pull must have the capability to react to a force in any direction. This may require a spring at the anchor point or an opposing rope pull switch The switch must have: A self-latching function that requires a manual reset after actuation Have direct opening operation Detect a slack condition or a break of the rope or cable WARNING: Emergency Stop Functions Do not mute or bypass any Emergency Stop device. ANSI B11.19, ANSI NFPA79 and IEC/EN 60204-1 require that the Emergency Stop function remain active at all times. 2 www.bannerengineering.com - tel: 763-544-3164 P/N 181295 Rev. A
