Warning
Accidental activation of actuators!
An incorrect status of the valves and outputs can lead to dangerous situations!
• Make sure that valves and outputs are put into a safe state when malfunctions oc-
cur.
• Check within the framework of your EMERGENCY OFF concept and the fail-safe set-
ting to ascertain the measures necessary for putting your machine or system into a
safe state.
Note
Take into account valve behaviour as part of the EMERGENCY OFF concept or of the
fail-safe setting!
If the outputs are reset when the controller stops or in case of network interruption,
telegram failure or a terminal malfunction, the valves will behave as follows:
– Monostable valves will move to their normal position
– Bistable valves remain in the current position
– Mid-position valves will move to their neutral position (pressurised, exhausted or
closed, depending on valve type)
