4.4
Reaction on bus voltage failure, recovery, download and ETS reset
The way in which the device responds on bus voltage failure or recovery, download and ETS reset are de-
scribed below.
Important
For system reasons, the device switches the outputs OFF for about 1 second after bus voltage
recovery, download or ETS reset. The response is the same after overload, short-circuit and supply
voltage recovery.
Switch off is not taken into account in the status objects.
After switch off, the outputs assume the current state.
4.4.1
Bus voltage failure
Fan or switch actuator response to bus voltage failure can be set.
4.4.2
Bus voltage recovery
A fan speed value can be predefined for bus voltage recovery. In
Switch actuator
mode, the commu-
nication object
Switch
can be written with 0, 1 or
not
written.
Status communication objects are sent provided that the option
Only after changing
or
After a change
or request
has been set.
The sent delay is only active at bus voltage recovery!
