Translation of the original operating instructions

6. MAINTENANCE, MALFUNCTIONS, POSSIBLE
CAUSES AND REMEDIES

The motor is sealed by ebm-papst. Changes or repairs may be carried
out by ebm-papst only.
The terminal box does not have to be opened for maintenance.
Do not perform any repairs on your device. Return the device to ebm-
papst for repair or replacement.

WARNING
Terminals and connections have voltage even with a
unit that is shut off

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

before opening the device.

CAUTION
If control voltage is applied or a speed setpoint is stored,
the motor automatically restarts, e.g. after a power failure.

Danger of injury
→ Keep out of the danger zone of the device.
→ When working on the device, switch off the mains

supply voltage and secure the latter from being switched on
again.

→ Wait until the device stops.
→ After working on the device, remove any used tools or

other objects from the device.

If the device remains out of use for over four months, we
recommend switching the device on for at least three hours at
full speed to allow any condensate to evaporate and to move
the bearings.

Malfunction/error

Possible cause

Possible remedy

Impeller running
roughly

Imbalance in rotating
parts

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.

Motor does not turn

Mechanical blockage

Switch off, de-
energise, and
remove mechanical
blockage.

Mains supply
voltage faulty

Check mains supply
voltage,
restore power
supply.
Important! The error
message resets
automatically.
The device starts
up again
automatically without
advance warning.

Faulty connection

De-energise, correct
connection, see
connection diagram.

Motor winding broken Replace device
Insufficient cooling

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.
Alternatively, reset
the error message
by applying a control
signal of <0.5 V to
DIN1 or by short
circuiting Din1 to
GND.

Ambient temperature
too high

Reduce the ambient
temperature. 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.
Alternatively, reset
the error message
by applying a control
signal of <0.5 V to
DIN1 or by short
circuiting Din1 to
GND.

Unacceptable
operating point (e.g.
counterpressure is
too high)

Correct the operating
point. 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.
Alternatively, reset
the error message
by applying a control
signal of <0.5 V to
DIN1 or by short
circuiting Din1 to
GND.
