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.
Please contact our technical service for the list of approved products.

Description
Rotating headsRemoving the four fastening screws, in all switches, it is possible to rotate the head in 90° steps.
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.

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 dia-grams are indicated both contacts.

In the diagram, the suggested max. rope lengths with regard to changes of temperature (thermal differential) to which the switch is expected to be exposed in the working area are indicated.For instance, for an example C installation which expects a thermal differential of 30°C, a max rope length of 10 meters is suggested.
Adjusting of intervention point
For switches with head 79 and 80: Stretch the rope connected to the switch, until the end of the indicator (1)
reaches about the middle of the green ring (2).
For switches with head 74: stretch the rope connected to the switch till the thimble will be at about 4 mm from
the head.
