4.3 Operating
mode:
“Switch actuator”
4.3.1 Parameter
window:
“General”
General settings can be carried out in this parameter window such as the
reaction during/after bus voltage failure and the status response function.
Parameter: “Status response of switching state”
The object “Status switch” is enabled with this parameter. It is used to
indicate the current switching state on the bus.
Parameter: “Status response inverted”
This parameter is visible if the
“Status response of switching state”
is carried
out. If “yes” is entered here, the status response object sends a “1” when the
relay contact is open and a “0” when the relay contact is closed. This can be
advisable for example when the output is operated as a normally closed
contact so that the telegram value “1” is received as a status response after
an ON command.
Parameter: “Sending after bus voltage recovery”
This parameter is visible if the
“Status response of switching state”
is carried
out. It can be set whether the switching state is updated on the bus after a
bus voltage recovery. The update is carried out in connection with the
transmission delay of the Room Controller.
Parameter: “Reaction on bus voltage failure”
The output can adopt a defined state on bus voltage failure via this
parameter.
It can be set in the parameter whether the output switches “ON” or “OFF”.
The contact position can also remain unchanged in the setting “unchanged”
(internal function is retained). In this case, the output can still be operated
e.g. via push buttons which are connected to binary inputs of the same
device.
Parameter: “Reaction on bus voltage recovery”
With this parameter, the output can be switched “ON” or “OFF” on recovery
of the bus voltage. In the setting “unchanged”, the state of the output does
not change.
On bus voltage recovery, the output is set once the parameterised
initialisation time of the Room Controller has elapsed.
