replace it if imbalance
persists after cleaning.
Make sure no
weight clips are
removed during
cleaning.
Motor not turning
Mechanical blockage
Switch off, isolate
from supply and
remove mechanical
blockage.
Line voltage faulty
Check line voltage,
restore power
supply, apply control
signal.
Faulty connection
Isolate from supply,
correct connection;
see connection
diagram.
Motor/electronics
overtemperature
Deficient cooling
Improve cooling. Let
the device cool down.
To reset the error
message, switch off
the line voltage for at
least 25 s and then
switch it on again.
Thermal overload
protector activated
Allow motor to cool
off, locate and rectify
cause of error,
release restart lockout
if necessary
Ambient temperature
too high
Reduce the ambient
temperature.
Reset by reducing
control input to 0.
Impermissible point of
operation
Correct the operating
point. Let the device
cool down.
In the event of further malfunctions, contact ebm-papst.
6.1 Vibration testing
Checking of fan for mechanical vibration based on ISO 14694.
Recommendation: Every 6 months. Max. vibration severity is 3.5 mm/
s, measured at the motor fastening diameter on the motor support plate in
the direction of the motor axis of rotation and perpendicular to this.
Fig. 1: Example illustrating vibration measurement. The arrangement of
the sensors depends on the device concerned and the installation
situation.
6.2 Cleaning
To ensure a long service life, check the fans regularly for proper
operation and soiling. The frequency of checking is to be adapted
accordingly depending on the degree of soiling.
DANGER
Risk of injury from rotating fan.
→ Only clean when not in motion. Do not disconnect the fan
from the power supply, just switch it off via the control input.
This will prevent start-up of the fan.
;
Dirt deposits on the motor housing can cause overheating of the motor.
;
Soiling of the impeller can cause vibration that will shorten the service
life of the fan.
;
Severe vibration can destroy the fan.
;
In such cases, switch off the fan immediately and clean it.
;
The preferred method of cleaning is dry cleaning, e.g. using
compressed air.
;
Do not use aggressive cleaning agents!
NOTE
Damage to the device during cleaning
Malfunction possible
→ Do not clean the device using a high-pressure cleaner.# Do
not use acid, alkali or solvent-based cleaning agents.
→ Do not use any pointed or sharp-edged objects for
cleaning.
;
Completely remove any cleaning agents used.
;
If severe corrosion is visible on load-bearing or rotating parts, switch
off the device immediately and replace it.
;
Repair of load-bearing or rotating parts is not permitted!
;
Operate the fan for 2 hours at maximum speed so that any water that
has ingressed can evaporate.
;
If cleaning does not eliminate vibrations, the fan may need to be
rebalanced. To have it rebalanced, contact ebm-papst.
;
The fan is equipped with maintenance-free ball bearings. The lifetime
lubrication of the ball bearings is designed for a service life of 40,000
hours.
