4G 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 Area of correct rope is high enough to permit the stretching black indicator to go outside the correct stretching area, there will be the opening of the safety contacts. Stretching indicator

In the rest position (with rope correctly tightened) the two contacts of contact block 8 are both closed and are activated respectively by actuating or loosening the rope. In order to use this contact block for safety applications is necessary to connect the two contacts in series. For this reason in wiring diagrams the contact block 8 is indicated as 1NC, whereas in travel diagrams are indicated both contacts.

4G 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 Area of correct rope is high enough to permit the stretching black indicator to go outside the correct stretching area, there will be the opening of the safety contacts. Stretching indicator

In the rest position (with rope correctly tightened) the two contacts of contact block 8 are both closed and are activated respectively by actuating or loosening the rope. In order to use this contact block for safety applications is necessary to connect the two contacts in series. For this reason in wiring diagrams the contact block 8 is indicated as 1NC, whereas in travel diagrams are indicated both contacts.
