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 three 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
Inadequate cooling

Improve cooling.
Allow the device to
cool down.

Ambient temperature
too high

Reduce the ambient
temperature. Allow
the device to cool
down.

Impermissible
operating point (e.g.
back pressure too
high)

Correct the operating
point. Allow the
device to cool down.

In the event of further malfunctions, contact ebm-papst.

6.1 Warning/status codes

The LED on the electronics housing shows the motor status with various
colors and flash codes. The flash codes have a frequency of 2 Hz.
Each flash code is followed by a pause lasting 3 seconds. The following
colors are used: Green: no warning or fault. Orange: There is a warning.
No user intervention is required for warnings. Red: There is at least one
error. See the following table. If there are multiple simultaneous errors,
their associated flash codes are displayed in succession. If there are
simultaneous warnings and errors, only the errors are displayed.
