Safety Function Definition

The safety function is an uncontrolled stop. The uncontrolled stop is
executed by removing the ArmorStart safety controller output voltage
in response to a DeviceNet Safety network command.

Limitations of the Safety-Related Parts

The user must provide other components to implement the overall
machine stop function. Example components are the DeviceNet
safety network, a safety PLC, and a safety input module.

Detection of the contactor state is provided so that a Category 4
architecture can be implemented for the overall machine stop
function. The user must provide a safety PLC and program to process
the “SM” feedback as required by Category 4. See configuration of
safety I/O module and Safety PLC Program.
