Starting at the tension springs, the pull rope is led\r\nthrough the eyebolts and hooked at both sides of the red tripping\r\nlever of the switch with turnbuckles. The pull rope is tensioned\r\nwith the turnbuckles in such a way that equal forces act on both\r\nsides of the tripping lever and it is found in the vertical operating\r\nposition. The tension of the rope has to be strong enough to actuate\r\nthe switch if the rope breaks.\r\nThe pull rope switch has to be positioned in the middle between\r\nthe two fixed points. The maximum distance between the fixed\r\npoints should not exceed approximately 100m. The choice of the\r\ndistance between the eyebolts is dependent on the ambient temperature\r\nrange and the length of the pull rope. A value of approximately\r\n2.5 m is recommended. The actuating travel of the tension\r\nsprings must be limited.\r\n\r\nThe function of the emergency stop system shall be checked in\r\nregular intervals of about 2 to 3 month.
