Note
Check within the framework of your EMERGENCY STOP
circuit, to ascertain the measures necessary for putting
your machine/system into a safe state in the event of an
EMERGENCY STOP.
Switching off the load voltage for the valves and output
modules in the secondary circuit of the power unit.
Switching off the compressed air supply for the valve
terminal.
Due to energy stored in the input circuitry of valve ter
minals, there may be a delayed reaction of the valves when
the load voltage is switched off.
Take this into consideration, e.g. as follows:
by using an input signal in the controller for checking
whether the load voltage has been switched off.
by blocking the control signal for the valves by locking
the output signal with the input signal Load voltage".
