After the start-up phase, a virtually constant bearing
temperature (T) is set, approximately three hours following
activation of the fan and with maximum permissible speed.
The normal bearing temperature during operation of the fan
is within a range of +55 … +80 °C, regardless of bearing size
and bearing lubrication.
Limit values for “pre-alarm” and “disconnection”:
Pre-alarm at
T > 80 °C
Disconnection at
T > 100 °C
NOTICE!
After initial activation of the fan, the bearing
temperature for grease-lubricated bearings can rise
above the limit value for “pre-alarm”. When the
excess grease has been exuded, the bearing
temperature must return to normal operating
temperature within the range of +55 … +80 °C.
