the period in which the vibration level has been exceed-

The sensor alarm signal (exceeded vibration level)
must always stop the blower. This can be done directly

It is possible to lower the alarm level by correcting the
% value. The alarm icon will then move to the selected
% value. It is necessary to log in as Admin to change
the % value.
If the blower stops due to too high vibration level, the
operator´s panel error icon will change from black to
flashing red. By pressing the icon, the field to the right
of "Vibration error" will turn red, to show the cause of
the error.
It is not recommended to set the % value higher than
80%, as the blower will stop when the alarm level
reaches 100% for 10 seconds.
