The Lifeline 3 system can be installed along or around awkward machinery such as conveyors and provides a constant-access emergency-stop facility. The Lifeline 3 is the only device of its kind to incorporate the following features in one unit making it the most versatile cable switch on the market. 1. The positive-mode mechanism ensures that the contacts are immediately latched open on actuation and can only be reset by the intentional action of turning the blue reset knob. The design also protects against nuisance tripping and the effects of thermal expansion. 2. The cable-status indicator makes the system easy to set up and maintain for spans up to 30m (98ft). 3. Four sets of contacts are provided: 2 N.C. + 2 N.O., 3 N.C. + 1 N.O., or 4 N.C. contacts. 4. Sealed to IP67 with rugged construction using die-cast alloy and stainless steel to withstand harsh conditions.

Important: It is recommended that the LRTS (Lifeline Rope Tensioning System) should be used with the Lifeline 3 cable rope switch.

The first and last P. Bolt must be located as close as possible to the switch eyelet while maintaining adequate clearance (125mm/5in) from the cable grips to allow free movement. This ensures a straight and efficient pulling action on the switches. 2. Additional P. Bolts, spaced 2-3m (6-9ft) apart, help keep the perpendicular pull force, F, and distance, d, within IEC60947-5-5 specifications of 200N (45lbs) and 400mm (15.75in). 3. We recommend using a switch at both cable ends, especially in applications with long cable runs or cable runs going around bends. This helps ensure that the safety function is fulfilled upon actuation of the cable in any direction. 4. ISO13850 (EN418) requires that the full length of cable to be within view when the reset is turned to the run position or the machine must be inspected over the whole length of the cable, both before and after resetting. 5. On shorter cable runs (max 10m), a Lifeline tensioner spring may be used at one end of the span. The installation must be such that the above requirements can be met. When a spring is used, the last P. Bolt must be located as close as possible to the spring while maintaining adequate clearance (125mm/5in) from the cable grips to allow free movement. This is intended to help to ensure that a pull near the end of the cable will be between P. Bolts. This should result in operation of the switch contacts instead of only the spring moving. 6. Careful attention is required for the design of the installation to ensure that the cable is not likely to become trapped or snagged. This is especially important when using a tensioner spring because a cable snag between the location of the pull and the switch could prevent the actuation of the safety function. 7. It is essential that when the installation is complete, a thorough functional test is made. This should include checking all types and directions of pull over the length of the cable as well as checking for slack-cable tripping. 6-6 Emergency Stop Devices Cable (Rope) Pull Switches Lifeline 3 Approximate Dimensions--mm (inches) Dimensions are not intended to be used for installation purposes. 56 (2.2) 43 (1.69) 10.5 (0.41) 60 (2.36) 204 (8.03) 4 x M5 mounting holes 40 (1.57 30 (1.18) Typical Wiring Diagrams 4 N.C. style 3 N.C. + 1 N.O. style 2 N.C. + 2 N.O. style 41 31 21 11 43 31 21 11 43 33 21 11 42 32 22 12 44 32 22 12 44 34 22 12 4 N.C.
