Operating instructions

K3G400-PA27-62

Translation of the original operating instructions

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.

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.
