Pressing the emergency stop / stop button
The emergency stop / stop button on the HMI device is an optional operator control. The
emergency stop / stop button is designed with two circuits and enables a safety-related
emergency stop or stop of the fail-safe automation system.
Whether the emergency stop / stop button has the "emergency stop" or "stop" function
depends on the configuration of the plant and the parameter settings of the HMI device.
If the emergency stop / stop button is configured and wired for the "emergency stop"
function, the emergency stop / stop button lights up as soon as the "emergency stop"
function becomes available.
An emergency stop or stop can only be triggered when the fail-safe HMI device is
attached to a connection box.
Emergency stop / stop button
For a hardwired F-system:
● When a SIRIUS safety relay is used, the emergency stop / stop button meets the
requirements of Safety Category 3 in accordance with EN ISO 13849--1.
● When you unplug the connecting cable from the connection box, the emergency stop
circuit is either opened or automatically bypassed, depending on the connection box
used.
For a PROFIsafe-based F-system: The emergency stop / stop button triggers the configured
function.
● The HMI device is connected to a correctly installed connection box.
● An operator control for the controlled hot restart of the plant is configured.
● For a PROFIsafe-based F-system only: A project for PROFIsafe communication has
started.
