Parameters
7.4.2.2.2.5
Reaction on bus voltage recovery Fan output
This parameter only applies to:
•
FCC/S 1.3.1.1
•
FCC/S 1.3.2.1
•
FCC/S 1.5.1.1
•
FCC/S 1.5.2.1
Options:
This parameter is used to specify the fan speed that is to apply after bus voltage recovery.
•
Unchanged: The same fan speed as before bus voltage failure applies. The status of the auto-
matic mode also remains unchanged. The fan follows the valve control value if the automatic
mode is active.
•
Applies control value: The speed is dependent on the valve control value. The automatic mode
is active. If the automatic mode was deactivated before the download, it is activated.
•
33 %: The fan runs with speed 33 % in the manual mode.
•
66 %: The fan runs with speed 66 % in the manual mode.
•
100 %: The fan runs with speed 100 % in the manual mode.
The Applies control value option is only available if it has not been deactivated in the Enable
automatic mode based on control value parameter in the Fan output window.
7.4.2.2.2.6
Control value after ETS download
Options:
This parameter specifies which control value is to apply after a download until the controller has
calculated a new control value.
The value specified here applies until a new control value has been received via the bus.
•
Unchanged: The same control value as before the download applies.
•
Select: A control value can be specified. This control value then applies until a new control
value is calculated/a new control value is received via the bus. The Control value dependent
parameter is displayed.
