Parameters Description
Hysteresis (COV)
This function is not needed for normal operation. It is used mainly
for diagnostics and troubleshooting.
● No COV, send when target position is reached: The current
valve position is only sent after position adjustment.
● At change of x %: The current valve position is sent if different
from the last sent value as of a value of x %. When the de-
fined actuating value is reached, the valve position is sent as
well. This happens even if the change is not reached as of the
last actuating value telegram.
NOTE: When no valve position is sent, the "Actual position" of the
object is not linked with a group address.
Cyclical transmission Defines if and how often the current valve position/actuating value
is transmitted.
● No cyclical transmission: The valve position is not transmitted.
● Every x min: The valve position is transmitted at intervals of x
min.
Minimum repetition time Defines the minimum repetition time interval for sending "Actual
position".
Drive to new valve
position setpoint (COV)
Defines the change of received "Setpoint position" that triggers
valve readjustment.
● Position always accurate: The valve is positioned upon each
actuating value change.
● At change of min. x %: The valve readjusts after actuating
value changes over x %.
Backup timeout Time communication is lost before the actuator enters emergency
mode. This parameter defines if and when reception of "Setpoint
position" via bus is monitored.
● 0 min: No monitoring of actuating values.
● x min: Time after which an actuating value is expected. The
recommended time is twice the expected cycle time.
