Parameter window A: General

Type of valve drive
Options:
This parameter defines the additional functions of the electrothermal valve drive output.
Note
De-energised closed valve drives (N.C. = normally closed)
If no current flows in the valve drive, the valve is closed. If current flows in the valve drive, the valve
opens.
De-energised opened valve drives (N.O. = normally opened)
If no current flows in the valve drive, the valve opens. If current flows in the valve drive, the valve then
closes.
Reaction after bus voltage recovery
Options:
This parameter determines the response of the output at bus voltage recovery.

unchanged: The last control value received before bus voltage failure is set. This also applies if a
function with a higher priority, e.g. Block, was active before bus voltage failure. If a value for control
in % at bus voltage failure is predefined, this will be reactivated at bus voltage recovery.

select: The following parameter appears:
