7.4.2.1.2
Selection of actuator device
The following parameters are visible if the
Actuator device
option has been selected in the
Device
function
parameter.
7.4.2.1.2.1
Reaction on bus voltage failure Fan output
This parameter is only visible for:
•
FCC/S 1.1.1.1
•
FCC/S 1.1.2.1
•
FCC/S 1.2.1.1
•
FCC/S 1.2.2.1
•
FCC/S 1.4.1.1
Options:
Unchanged
OFF
The reaction of the fan output on bus voltage failure is specified using this parameter.
•
Unchanged
: The currently applicable fan speed is maintained on bus voltage failure.
•
OFF
: The fan is switched off if there is a bus voltage failure.
7.4.2.1.2.2
Reaction on bus voltage failure Relay output
This parameter is not available for the variant FCC/S 1.4.1.1.
Options:
Unchanged
On
Off
The reaction of the relay output on bus voltage failure is specified using this parameter.
•
Unchanged
: The relay remains in its actual position on bus voltage failure.
•
On
: The relay is switched on if there is a bus voltage failure.
•
Off
: The relay is switched off if there is a bus voltage failure.
7.4.2.1.2.3
Control value after bus voltage recovery
Options:
As before bus voltage failure
Select
The value specified here applies until a new control value has been received via the bus.
•
As before bus voltage failure
: The same control value as before the bus voltage failure applies.
•
Select
: A control value can be specified. This control value applies until a new control value is
calculated/a new control value is received via the bus. The
Control value
dependent parameter
is displayed.
Note
The reaction parameterized here also applies during the sending and switching delay.
After bus voltage recovery it can take up to 2 seconds until the device has started and the out-
puts can be switched/controlled again.
