Description
These rope operated safety switches are installed on machines or conveyor belts, to activate the simple stop of the machine on every hand intervention on the rope, from any point. Provided with self-control function, they constantly check their correct working operation, signalling with the opening of the contacts an eventual loosening or breaking of the rope.
Rotating Heads
Removing the four fastening screws, in all switches, it is possible to rotate the head in 90° steps.
Rope regulation point indicator
The switches (head 79 and 80) are provided with a green ring that shows the area of the correct stretching of the rope. The installer has only to stretch the rope until the black indicator will be in the middle of the green area. If a traction (or loosening) of the rope it is high enough to permit the black indicator to go outside the correct stretching area, there will be the opening of the safety contacts.
Adjusting of intervention point
For switches with head 79 and 80: Stretch the rope connected to the switch, until the end of the indicator reaches about the middle of the green ring.
For switches with head 74: stretch the rope connected to the switch till the thimble will be at about 4 mm from the head.
