6-4 emergency stop devices cable (rope) pull switches lifeline 3 description the lifeline 3 is a cable (rope) operated emergency stop device designed to meet the stringent re quirements of en 418 (safety of machinery?emergency stop equipment). 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. features ? switches up to 30m (98ft) span ? universal mounting and operation ? switch lockout on cable pulled and cable slack ? cable-status indicator on switch lid ? industry standard fixing centres to din/en 50041 ? quick disconnect styles available. typical applications specifications standards en 418, iso 13850, isotr 12100, iec 60947-5-1, iec 60947-5-5 approvals ce marked for all applicable directives, culus and tuv safety contact 2 n.c. or 3 n.c. or 4 n.c. direct opening action designation/utilization cat. a600/ac-15 (ue) (ie) n600/dc-13 (ue) (ie) 600v 500v 240v 120v 1.2a 1.4a 3a 6a 600v 500v 250v 125v 0.4a 0.55a 1.1a 2.2a thermal current (lth) 10 a minimum current 5 v 5 ma safety contact gap >2 x 2mm (0.078in) rtd. impulse withstand volta ge (uimp) 2500 v pollution degree 3 max. actuation frequency 1 cycle/s case material heavy-duty die-cast aluminium alloy (lm24) eye nut material stainless steel indicator material glass filled nylon protection ip67 conduit entry 1 x 1/2in npt, 1 x m20, quick- disconnect style operating temperature -25c to +80c (-13f to +176f) operation force <125n (28.1lb) (300mm deflection) tensioning force to run position 103n (23.17lb) typical tensioning force to lockout 188n (42.3lb) typical max. cable span between switches 30m (98.42ft) fixing (mounting holes) 4 x m5 mounting any position mechanical life 1,000,000 weight 610g (1.34lb) colour yellow body, blue reset button important : it is recommended that the lrts (lifeline rope tensioning system) should be used with the lifeline 3 cable rope switch.

6-6 emergency stop devices cable (rope) pull switches lifeline 3 application detailsmm (inches) notes: 1. the first and last p. b o l t 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 st raight and efficient pulling action on the switches. 2. additional p. b o l t s, 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 be nds. 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 with in 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 suc h that the above requirements can be met. when a spring is used, the last p. b o l t 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. b o l t s. 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 p revent the actuation of the safety function. 7. it is essential that when the installation is complete, a thorou gh 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. lifeline 3 cable grips polypropylene-covered steel cable tensioner p. b o l t s tension indicator reset knob lifeline 3 tensioner spring tension indicator wall 125 (5) 2-3m (6-9ft) d f 2-3m (6-9ft) 125 (5) 30m (98ft) 12 2 1 3 4 2 125 (5) 2-3m (6-9ft) d f 2-3m (6-9ft) 125 (5) 10m (32ft) 12 2 5 2 1 6
