The values assigned to the rating zones are not intended to
serve as acceptance values. The acceptance values have to
be specified between the machine manufacturer and the
customer. The values should serve as guidelines to avoid
major errors or unrealistic requirements.
The above shown warning and disconnecting values regarding
the working temperature are maximum values. They are
related to an ambient temperature of 40°C and an altitude of
installation of up to 1000 m asl. Under special circumstances
these values can be exceeded, if the preceding agreement
of the manufacturer is obtained.
Evaluation criteria regarding vibrations according to German
standard DIN ISO 10816/3.
If the vibration values level out between warning and disconnecting
and if the fan is carefully observed, the operating of
the fan can be continued until a proper point of time is defined,
so the process can be shut down in a controlled way.
Possible damages of the fan can not be excluded � if required,
