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
Impeller not Imbalance in rotating
running smoothly parts
Motor not turning Mechanical blockage
Line voltage faulty
Faulty connection
Broken motor winding Replace device
Inadequate cooling

Operating instructions

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.
