Object value "Switch"
on bus voltage recovery
Options:
not write
write with 0
write with 1
With this parameter, the output can be influenced by the value of the Switch
communication object on bus voltage recovery.
The Switch communication object can be written with either a 0 or 1 when
the bus voltage recovers.
The contact position is redefined and reset in dependence on the set device
parameterisation.
not write: The value 0 is written in communication object Switch and
remains so until the communication object is changed via the bus.
The contact position is only re-evaluated at this time.
Note
The reaction on bus voltage failure, recovery and download is to be
monitored.
The Fan Coil Actuator draws the energy for switching the contact from the
bus. After bus voltage is applied, sufficient energy is only available after
about ten seconds in order to switch all contacts simultaneously.
Depending on the set transmission and switching delay after recovery of
bus voltage set in the parameter window General, the individual outputs
will only assume the desired contact position after this time.
If a shorter time is set, the FCA/S will only switch the first contact when
sufficient energy is stored in the actuator, in order to ensure that enough
energy is available to immediately bring all outputs safely to the required
position with a renewed bus voltage failure
Enable function time
Options:
no
yes
yes: An additional parameter window appears in which the staircase
lighting time is programmed.
At the same time the communication object block staircase lighting
is enabled.
