Mechan ControlsSafeline 4 Rope Pull Safety Switch

The stainless steel Safeline 4 cable/push button operated pull rope safety switch from Mechan Controls can be installed where no physical guard is present, such as with conveyer belts. The pull rope safety switch can provide constant emergency stop access. The switch is made from 316 stainless steel and is suitable for use in areas with hygiene requirements, external use, and use in situations where a level of corrision proofness is required.

Seperate tensioner kit needed!

1. The blue reset knob must be intentionally turned in order to reset the contacts, which are automatically locked open upon actuation thanks to the positive mode mechanism. Additionally, the design guards against the effects of thermal expansion and annoyance tripping.
2. To enable E-Stop access, the device has an optional mushroom head emergency stop button.
3. For spans up to 75 metres, the system is simple to set up and maintain thanks to the cable status indicators.
4. There are four contact sets available: 3NC + 1NO or 2 N.C. + 2 N.O.
5. Built tough with 316 stainless steel and sealed to IP69K to endure challenging circumstances.
6. Windows for tension indicators on both sides of the lid, to make tensioning easier.

Conform to ISO13850(EN 418) and IEC60947-5-5. Safety related data: SIL3, PLe, CAT4 (all only if connected to a safety relay or safety PLC) en IP69K.

Use:

By pre-tensioning the rope and using a tensioner/gripper device that clamps the rope and then hooks to the switch eyebolts, the SL4 switch is made operational. By looking at the tension indicators on both sides of the housing, one may determine the correct tension. The machine/safety relay is now ready to operate. After the switch contact blocks have been tensioned, they can be set to the operational condition (safety contacts closed, auxiliary contacts open) by setting the blue switch to the "run" position. When the rope breaks (tension loss) or the red E-stop is pulled or pressed, the auxiliary connections close and the safety contacts open. After being mechanically latched, the SL4 can only be put back into operating condition by flipping the blue rest switch to the "run" position, in accordance with ISO13850 (EN418).
