Translation of the original operating instructions
Fig. 1: Example illustrating vibration measurement. The arrangement of
the sensors depends on the device concerned and the installation
situation.
If the device is out of use for some time, e.g. when in storage,
we recommend switching it on for at least two hours to allow
any condensation to evaporate and to move the bearings.
Malfunction/fault
Possible cause
Possible remedy
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
Thermal overload
protector activated
Allow motor to cool
off, locate and rectify
cause of error,
release restart lockout
if necessary
Deficient cooling
Improve cooling. Let
the device cool down.
To reset the error
message, switch off
the line voltage for at
least 25 s and then
switch it on again.
Alternatively, reset
the error message by
applying a control
signal of < 0.5 V to
Din1 or by shorting
Din1 to GND.
Ambient temperature
too high
Reduce the ambient
temperature. Let the
device cool down.
To reset the error
message, switch off
the line voltage for at
least 25 s and then
switch it on again.
Alternatively, reset
the error message by
applying a control
signal of < 0.5 V to
Din1 or by shorting
Din1 to GND.
Impermissible point of
operation (e.g. back
pressure too high)
Correct the operating
point. Let the device
cool down.
To reset the error
message, switch off
the line voltage for at
least 25 s and then
switch it on again.
Alternatively, reset
the error message by
applying a control
signal of < 0.5 V to
Din1 or by shorting
Din1 to GND.
