Special operating states
4.6.1
Reaction on bus voltage failure, recovery, download and ETS reset
The device reaction on bus voltage failure, recovery, download and ETS reset can be set in the de-
vice parameters.
NOTICE
If the allocation of the outputs is changed (e.g.
Actuate basic-stage heating via
from
Internal out-
put A (valve)
to
Group object
) when the device is parametrized, a reset must be performed to en-
sure proper functioning of the outputs.
4.6.1.1
Bus voltage failure
Bus voltage failure describes the sudden drop in/failure of the bus voltage, e.g. due to a power fail-
ure.
4.6.1.2
Bus voltage recovery
Bus voltage recovery is the state after bus voltage is restored after failing previously due to a bus
voltage failure.
4.6.1.3
ETS reset
Generally an ETS reset is defined as a reset of the device via ETS. The ETS reset is triggered in
the ETS under the menu item Commissioning with the function
Reset device
. This stops and
restarts the application.
4.6.1.4
Download
Downloading describes loading a modified or updated application into the application with the ETS.
Note
After the application is removed or after an interrupted download, the device no longer functions.
