10.4 Connection of external emergency stop
About emergency stop connections
An external emergency stop can be connected either directly to the panel board
in the IRC5 controller or to the safety PLC that communicates the emergency stop
to the safety controller.
CAUTION
A safety stop from the safety PLC will always trigger a protective stop on the
superior stop input (SS) of the IRC5 panel board.
A safety stop from the safety PLC will not affect external units that may be
connected to the automatic stop input (AS), general stop input (GS), or the
emergency stop input (ES) of the IRC5 panel board. For example: external
emergency stop buttons, light curtains, door breakers, etc.
The safety circuit is separated from stops triggered by external units and stops
triggered by the safety unit or safety PLC. This means that a safety stop on the
panel board that is generated by external units will by default not generate a stop
on the safety unit or a connected safety PLC. The stop can be read by the safety
unit and reported to the safety PLC using predefined global signals.
Connecting emergency stop to panel board
If the external emergency stop is connected to the panel board, it is connected in
serial with the local emergency stop on the same circuit.
