Installation for safety applications:

Use only switches marked with the symbol next to the product code. Always connect the safety circuit to the NC contacts (normally closed

contacts: 11-12, 21-22 or 31-32) as required by EN ISO 14119, paragraph 5.4 for specific interlock applications and EN ISO 13849-2 tables D3

(well-tried components) and D.8 (fault exclusions) for safety applications in general. Actuate the switch at least up to the positive opening

travel shown in the travel diagrams on page 228. Actuate the switch at least with the positive opening force, reported in brackets below each

article, next to the actuating force value.

The majority of switches can be equipped with a reset device (option W3) which enables the simultaneous actuation of actuator and contact block. The device is a module that is mounted between the body and the head of the switch that can be rotated independently from the head. The reset device has the following advantages:

•can be integrated into the majority of standard actuator heads;

•contact blocks with snap action are no more necessary because the tripping movement is executed by the reset device itself;

•can be rotated independently from the head ensuring maximum flexibility during installation;

•can be delivered with two different actuating forces: standard and increased for vibration applications;

•mechanical endurance: 1 million operating cycles.
