Operating instructions

K3G280-PR04-I2

Translation of the original operating instructions

Faulty connection

De-energise, correct
connection, see
connection diagram.

Thermal overload
protector responded

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

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.

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 Vibration test

Checking the fan for mechanical vibrations based on ISO 14694.
Recommendation: every 6 months. Maximum vibration severity is 3.5
mm/s measured at the motor’s fastening diameter on the motor support
plate towards and perpendicular to the motor’s axis of rotation.

Fig. 1: Example showing vibration measurement. Positioning of the
sensors will vary depending on the device and the circumstances of
installation.

6.2 Cleaning

NOTE
Damage to the device during cleaning

Malfunction possible
→ Do not use a high-pressure cleaner to clean the device.# Do

not use any acid, alkali or solvent-based cleaning agents.

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

6.3 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 or
replace impeller

Condensate
discharge holes
for clogging, as
necessary

Visual inspection At least every

6 months

Open bore holes

Abnormal
bearing noise

acoustic

At least every
6 months

Replace device

Vibration test

Vibration meter,
ramp-up or
ramp-down
measurement

Recommended
every 6 months

Clean and
rebalance
impeller,
replace if
necessary
