Operating instructions

D3G250-ED01-71

Translation of the original operating instructions

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,
apply control signal.

Faulty connection

De-energise, correct
connection, see
connection diagram.

Overtemperature of
electronics/motor

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.

Thermal overload
protector responded

Allow motor to cool
off, locate and rectify
cause of error, if
necessary cancel
restart lock-out

Ambient temperature
too high

Reduce the ambient
temperature.
Reset by reducing
control input to 0.

Unacceptable
operating point

Correct the operating
point. Let the device
cool down.

If you have any other problems, contact ebm-papst.

6.1 Cleaning

To ensure a long service life, the fans have to be regularly checked for
proper operation and degree of soiling. The frequency of the checks is to
be adapted to the occurrence 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 could lead to overheating of the
motor.

;

Dirt on the impeller can cause vibration which would shorten the
service life of the fan.

;

Severe vibration could destroy the fan.

;

In such cases immediately switch off and clean the fan.

;

The preferred method of cleaning is dry cleaning, e.g. using
compressed air.

;

Use is never to be made of corrosive cleaning agents!

NOTE
Damage to the device during cleaning

Malfunction possible

→ Do not clean the device using a water jet or high-pressure

cleaner.

→ Do not use any acid, alkali or solvent-basedcleaning

agents.

→ Do not use any pointed or sharp-edged objects for cleaning

;

Completely remove any cleaning agents used.

;

Immediately switch off and replace the device if severe corrosion is
apparent at load-bearing or rotating parts.

;

Repairs to load-bearing or rotating parts are not permissible!

;

Operate the fan for 2 hours at maximum speed to permit the
evaporation of any water which may have ingressed.

;

If cleaning does not eliminate vibration, the fan may have to be re-
balanced. In such cases please contact ebm-papst.

;

The fan is provided with maintenance-free ball bearings. The lifetime
lubrication of the ball bearings is designed for a service life of 40,000
hours.

;

Please contact ebm-papst if bearing replacement is required after this
period.

;

Adapt the maintenance intervals to the dust pollution occurring.

6.2 Safety test

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.

What has to
be tested?

How to test?

Frequency

Which
measure?

Check the
protective
casing against
accidental
contact for
damage and to
ensure that it is
intact

Visual inspection At least every

6 months

Repair or
replacement of
the device

Check the
device for
damage to
blades and
housing

Visual inspection At least every

6 months

Replacement of
the device

Mounting the
connection lines

Visual inspection At least every

6 months

Fasten

Mounting of
protective earth
connection

Visual inspection At least every

6 months

Fasten

Check the
insulation of the
wires for damage

Visual inspection At least every

6 months

Replace wires

Impeller for
wear/deposits/
corrosion and
damage

Visual inspection At least every

6 months

Clean impeller
or replace device

Abnormal
bearing noise

acoustic

At least every
6 months
