Enable limitations
Option: No
Yes

Yes : Four communication objects, Limitation x , (x = 1...4), are enabled for limitation of the fan speed.
Speed ranges (limitations) are defined for the fan with the speed limitation function which may not be
over/undershot.
Important
The parameterized start-up behavior which is a technical characteristic of the fan has a higher priority
than a limitation, i.e. if a limitation is activated in fan speed 2 and start-up behavior is parameterized with
fan speed 3, the following behavior will result: The fan is in the OFF state and receives a control signal
for fan speed 1. First it goes to speed 3 (start-up speed), then 2, which is specified via the limitation.
Due to the limitation, the actual required fan speed 1 will not be reached.
The sequence of the displayed parameters corresponds with their priorities, i.e. the parameter with the
highest priority has limitation 1 followed by limitations 2, 3 and 4.
When you exit automatic mode, e.g. by a manual action, the
limitations 1…4 remain.
The following points apply for limitations:

The limitation need not necessarily apply to one fan speed only. It can also encompass another range
of the fan speeds, i.e. only certain fan speeds can be set if the limitation is active. In this way, a limited
control is also possible.

The limitation is activated when a telegram with the value 1 is received on the limitation communica-
tion object, and is lifted when the same object receives a telegram with the value 0. A manual action
ends automatic operation.

If a limitation is activated, the device switches to the parameterized fan speed regardless of the control
value. If another fan speed or a speed outside the "limitation range" is set when the limitation is acti-
vated, then the required speed or the limit speed of the range is set.

After limitations are switched off, fan speed is recalculated and executed. This means that during limi-
tation the actuator operates normally in the background, the outputs are not changed and implementa-
tion only occurs once limitation ends.
Each of the four limitations used to limit the fan speeds has the same parameters. They are prioritized ac-
cording to the listed sequence. The highest priority is assigned to limitation 1 and the lowest to limitation 4.
