Note
Shutdown auxiliary equipment
If auxiliary equipment is also to be shut down using the "Prewarning time expired" signal, which
acknowledges the shutdown process, then using a normal PLC timer and the signal "PLC user
program signal", a monitoring function can be installed in the basic PLC program. If the auxiliary
equipment has still not been run down after the PLC timer has expired, then the energy-saving
state can be exited again using the "PLC user program signal".

Function
This signal is set by the basic PLC program (FB15) if the timer has expired and the pre‐
warning is output on the HMI.
This signal is set by the basic PLC program (FB15) if, after the prewarning limit has been
reached, also the prewarning time of the corresponding energy profile has expired. This
means that this signal is equivalent to the information "Energy-saving state active".
Directly activate energy-saving profile
Set time to prewarning limit
Directly activate energy-saving profile
Master computer prohibits energy-saving state
PLC user program signal prohibits energy-saving state
