Function description for the variants
LineStrong1
LineStrong1 is a compact and small, yet robust switch that can handle wires up to 30 meters on a single
switch (50 meters on two switches).
When someone pulls the wire of Linestrong1 or if the wire is broken, the switch goes to a safe state, e.g. the
machine is emergency-stopped. After a emergency stop the LineStrong1 needs to be reset to be able to run
again and this is made on the local reset button. LineStrong1 is equipped with an indication of how taut the
wire is, which make the installation or adjustment easy.
The LineStrong1 is made of a rugged die cast housing with a rating of IP67.
A positive forced connection provides a forced disconnect of the safety contacts when the wire is being
pulled or broken. The design of the LineStrong1 ensures that the contacts will not fail or be held in a
normally closed position, due to failure of the spring mechanism or that welding/sticking of the contacts
can occur. The LineStrong1 switch has 2NC and 2NO contacts.
We recommend installing the eye bolts across the whole length of the rope between the switches at min.
2.5 m to max. 3 m. If this cannot be achieved, please see “Distance between eyebolts”.
