Warning
Accidental activation of actuators!
Incorrect statuses of valves and outputs can lead to dan-
gerous situations!
•
Make sure that valves and outputs are put in a safe state
when malfunctions occur.
•
In the context of your EMERGENCY STOP concept
and fail-state settings, check what measures are neces-
sary in order to put your machine/system in a safe state.
Typical safety measures required to put system in safe
state:
– Switch off the load voltage for the valves and output
modules in the secondary circuit of the power unit
– Switch off the compressed air supply to the valve termin-
al
Due to energy stored in the input circuitry of valve termin-
als, valves may display a delayed response when the load
voltage is switched off.
Take this situation into account, for example by:
– using an input signal in the controller to check whether
the load voltage has been switched off
– blocking the valve switching signal by locking the output
signal with the “load voltage” input signal
