Special operating states

4.5.1

Reaction on bus voltage failure/recovery, download and ETS reset

The device's reaction on bus voltage failure/recovery, download and ETS reset can be set in the device
parameters.
CAUTION –
If the allocation of the outputs is changed (e.g. Actuate basic-stage heating via from Internal channel
output (valve) to Group object) when the device is parametrized, the device resets automatically to
ensure the correct function of the outputs.
4.5.1.1

Bus voltage failure

Bus voltage failure describes the sudden drop in/failure of the bus voltage, e.g. due to a power failure.
4.5.1.2

Bus voltage recovery

Bus voltage recovery is the state after bus voltage is restored after failing previously due to a bus voltage
failure.
4.5.1.3

ETS reset

Generally an ETS reset is defined as a reset of the device via ETS. To trigger an ETS reset, go to the ETS
Commissioning menu and select Reset device. This stops and restarts the application.
4.5.1.4

Download

Downloading describes loading a modified or updated application onto the device with ETS.
After the application is uninstalled or after an interrupted download, the device no longer functions.
