ASIMON V3 - Configuration software for AS-Interface safety monitor
Programming and Operating Manual, Edition 09/2008, GWA 4NEB 333 1558 02 DS 02 75
Description
The zero sequence detection monitoring device can be used to monitor whether both swit-
ches of a safe input slave are open. It is used to perform operational switching tasks. The de-
vice switches to the ON state when the value 0000 is continuously transmitted by the safe
slave. With zero sequence detection, safe input slaves which are included at a different point
in the configuration can also be monitored. And vice versa, the address selected for zero se-
quence detection for monitoring devices remains available.

Notice
In the event of a defect or error, e.g. insufficient voltage at the slave, the ON state can also be
achieved when both switches are closed. For this reason, it is not permitted to use a zero
sequence detection device for safe switching tasks!
Example: Zero sequence detection device
0020 INDEX: 32 = "Name"
