AS-Interface position switches

Overview

 

Application

 

 

Position switch with separate actuator

 

 

The position switches with separate actuator are used in appli-

 

 

cations in which the position of doors, covers or guards has to

 

 

be monitored for safety reasons.

 

 

The position switch can only be switched using the associated

 

 

coded actuator. It is not possible to bypass it manually or using

 

 

a tool.

 

 

Position switch with tumbler

 

 

The position switches with tumblers are special safety devices

 

 

that prevent the inadvertent or intentional opening of protective

 

 

doors, guards or other covers when a dangerous state exists,

 

 

e.g. for coastdown movements of the switched-off machine.

The safety switch with tumbler has two main tasks:

Enabling the machine when the protective device is closed and locked

Disabling the machine when the protective device is open

The position switch can only be switched using the associated coded actuator. It is not possible to bypass it manually or using a tool.

It is also possible now to directly connect SIGUARD position

switches via the standard AS-Interface with safety-oriented com- munication. In this case, the safety functions no longer have to be conventionally wired up.

Position switches convert the mechanical positions of moving machine components into electrical signals.
