6.1 Vibration test

Checking the fan for mechanical vibrations based on ISO 14694.
Recommendation: every 6 months. Maximum vibration severity is 3.5
mm/s measured at the motor's fastening diameter on the motor support
plate towards and perpendicular to the motor's axis of rotation.

Operating instructions
Clean the device; if
imbalance is still
evident after cleaning,
replace the device.
If you have
attached any weight
clips during cleaning,
make sure to remove
them afterwards.
Switch off, de-
energise, and
remove mechanical
blockage.
Check mains supply

connection diagram.

6.2 Cleaning

Improve cooling. Let
the device cool down.
To reset the error
message, switch off
the mains supply
voltage for a min. of
25 s and switch it on
again.
Allow motor to cool

6.3 Safety test

off, locate and rectify
cause of error, if
necessary cancel
restart lock-out
Reduce the ambient
temperature.
Reset by reducing
control input to 0.
Correct the operating
point. Let the device
cool down.
What has to
be tested?
Check the
protective
casing against
accidental
contact for
damage and to
ensure that it is
intact
Check the
device for
damage to
blades and
housing
Mounting the
connection lines
Check the
insulation of the
wires for damage
NOTE
Damage to the device during cleaning
Malfunction possible
→ Do not use a high-pressure cleaner to clean the device.# Do
not use any acid, alkali or solvent-based cleaning agents.
→ Do not use any pointed or sharp-edged objects for cleaning
NOTE
High-voltage test
The integrated EMC filter contains Y capacitors. Therefore, the
trigger current is exceeded when AC testing voltage is applied.
→ Test the device with DC voltage when you carry out the
high-voltage test required by law. The voltage to be used
corresponds to the peak value of the AC voltage required by
the standard.
