Translation of the original operating instructions

6. MAINTENANCE, MALFUNCTIONS, POSSIBLE
CAUSES AND REMEDIES

Do not perform any repairs on your device. Send the device to ebm-
papst for repair or replacement.

WARNING
Live terminals and connections even with device
switched off

Electric shock
→ Wait five minutes after disconnecting the voltage at all poles

before opening the device.

CAUTION
If control voltage or a stored speed set value is applied,
the motor will restart automatically, e.g. after a power
failure.

Risk of injury
→ Keep out of the device’s danger zone.
→ When working on the device, switch off the line voltage

and ensure that it cannot be switched back on.

→ Wait until the device comes to a stop.
→ After working on the device, remove any tools or other

objects from the device.

NOTE

If the device is not operated for a lengthy period in installed
condition in a dry environment, it is to be started up and
operated at full speed for one hour at least every four months. If
the device is not operated for a lengthy period in installed
condition in a damp environment (e.g. outdoors), it is to be
started up and operated at full speed for at least two hours once
a month to move the bearings and allow any condensate that
may have ingressed to evaporate.

Malfunction/fault

Possible cause

Possible remedy

Impeller not
running smoothly

Imbalance in rotating
parts

Clean the device;
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.
Attention! The error
message resets
automatically.
Device restarts
automatically without
warning.

Faulty connection

Isolate from supply,
correct connection;
see connection
diagram.

Broken motor winding Replace device

Thermal overload
protector activated

Allow motor to cool
off, locate and rectify
cause of error,
release restart lockout
if necessary

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.
Alternatively, reset
the error message by
applying a control
signal of < 0.5 V to
Din1 or by shorting
Din1 to GND.

Ambient temperature
too high

Reduce the ambient
temperature. 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.
Alternatively, reset
the error message by
applying a control
signal of < 0.5 V to
Din1 or by shorting
Din1 to GND.

Impermissible point of
operation (e.g. back
pressure too high)

Correct the operating
point. 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.
Alternatively, reset
the error message by
applying a control
signal of < 0.5 V to
Din1 or by shorting
Din1 to GND.

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.
