Emergency stop, stop
The operator presses the emergency stop / stop button to activate either an emergency stop
or a stop.
●
The emergency stop is an emergency action that is intended to stop a process or
movement entailing danger. All machines that are assigned to the trigger are immediately
brought to a safe state via the emergency stop.
●
The emergency stop / stop button of the HMI device brings about a safety-related stop of
the plant or machine in accordance with EN 60204-1, Section 9.2.5.3.
Whether the emergency stop / stop button causes an "emergency stop" or "stop" function
must be decided upon and configured on the basis of the risk analysis.
Safety-related operating mode
In fail-safe mode, you can use the HMI device in combination with a connection box in one of
the following operating modes:
●
Stop button evaluated by safety relay
The signals of the safety-related operator controls are wired to a safety relay. If you press
the emergency stop / stop button, the plant typically responds with a stop.
The emergency stop / stop button does not light up.
In this operating mode, the emergency stop / stop button is called the stop button.
●
E-stop button evaluated by safety relay
The signals of the safety-related operator controls are wired to a safety relay. When you
press the emergency stop / stop button, the plant responds with an emergency stop.
The emergency stop / stop button lights up when active.
In this operating mode, the emergency stop / stop button is called the emergency stop
button.
Emergency stop / stop bypass
The emergency stop / stop bypass is a function of the connection box advanced for
hardwired F-systems.
The function ensures that no stop or emergency stop will be triggered in the plant when
reconnecting the Mobile Panel to another connection box.
