PC-Tool User Manual
for Damper and Valve Actuators
VAV 4 +/- 6 V When this function is selected, the actuator is parameterized as a VAV
actuator and can therefore be controlled by the VAV controllers VR.. .
Note:
When VAV (6 ± 4 V) is selected, the values for minimum, maximum,
intermediate value, running time and angle of rotation/stroke are reset to
the default values.
4–20 mA (Direct current)
Fixed operating range DC 4–20 mA
Note:
This selection is only available for certain drives (e.g. "SunYeh")
mA variable (Direct current)
The values for start and stop are specified in the actuator and cannot be
changed with the PC-Tool.
Note:
This selection is only available for certain drives (e.g. "Butterfly
Actuators")
Feedback U5 (only active when the actuator address is set to PP)
Damper position,
2–10 V
DC voltage measurement signal, fixed range
Damper position,
0.5–10 V
DC voltage measurement signal, fixed range
Damper position,
variable
DC voltage measurement signal
Start 0.5...8.0 V / Stop 2.5 ... 10.0 V
Range between start and stop at least 2 V
Damper position,
4–20 mA
Direct current measurement signal, fixed range
... Certain actuators can define further feedbacks, which you cannot
change, however.
U5 scaling (only with "New Generation" actuator, MFT or MP types)
Start Position in percent, corresponds to the start value of the feedback signal
Stop Position in percent which corresponds to the stop value of the feedback
signal
Angle of rotation (for full-rotation actuators)
Stroke (for linear actuators)
Min Programmed lower limit of the range
Mid Mid-position of range
Max Programmed lower limit of the range
