Zero sequence detection
The zero sequence detection monitoring device can be used to monitor whether both switches
of a safe input slave are open. The device switches to the ON state when the value 0000 is
continuously transmitted by the safe slave.
Application icons
The safe monitoring devices generally differ from one another only in type, e.g. double channel
dependent. From an application perspective, a device of the same type can be used both as a
safety guard as well as for two-handed operation.
Described in the following are the safe monitoring devices organised according to type. In the
icon library, you must first select the application icon for the desired device and then select the
respective type in the input mask.
To the left of the application icon in the configuration window, the type icon (double channel
forced, double channel dependent, double channel independent, etc.) is displayed for all safe
monitoring devices in order to clearly represent the configuration with a practical perspective.
The input mask of the application icons offers all device options, even if e.g. a local acknow-
ledgement for a two-handed operation does not make much sense.
Device options
Many monitoring devices also possess, in addition to their safe switching behaviour, options
which can be used to realise more complex applications. These include:
Startup test
The startup test is used, for example, when the proper function of a safety guard is to be in-
spected prior to starting the machine. In this case, the startup test requires that the guard be
opened and closed again before the machine is started. Only then can the machine be started.
Notice
The use of a zero sequence detection device for safe switching tasks is not permitted!
