This system manual applies to the following Fuchs GmbH equipment:
2.1.1
AS-i Safety Monitor for 2 AS-i circuits
The AS-i Safety Monitor in a stainless steel enclosure is an E-STOP switching de-
vice which monitors safety configured slaves and correct function of the network.
The safety unit provides 4 inputs which can be defined as either EDM or as
START inputs.
The unit features two hierarchically equal AS-i circuits and four output switching
elements (two safety relays and two semiconductor outputs).
Features:
•
Greater computing power to allow more function modules
•
Graphical display for better diagnostics
•
Optional storing of configuration data on an interchangeable memory card.
•
EDM & START inputs can be defined freely

Brief description
The Actuator-Sensor-Interface (AS-i) has been established as a system for net-
working primarily binary sensors and actuators on the lowest level of the automa-
tion hierarchy. The large number of installed systems, ease of use and reliable
operating behavior make AS-i also ideal for machine safety applications.
