Operating instructions
6. MAINTENANCE, MALFUNCTIONS, POSSIBLE
CAUSES AND REMEDIES
Do not perform any repairs on your device. Send the device to Systemair
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 danger zone.
→ When working on the device, switch off the line voltage
and ensure that it cannot be switched back on.
→ After working on the device, remove any tools or other
objects from the device.
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, apply control
signal.
Faulty connection Isolate from supply,
correct connection;
see connection
diagram.
Motor/electronics
overtemperature
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.
Ambient temperature
too high
Reduce the ambient
temperature.
Reset by reducing
control input to 0.
Impermissible point of
operation
Correct the operating
point. Let the device
cool down.
In the event of further malfunctions, contact Systemair.
6.1 Cleaning
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
6.2 Safety inspection
NOTE
High-voltage test
The integrated EMC filter has Y capacitors. The tripping current
is exceeded when AC testing voltage is applied.
→ Test the device with DC voltage when you perform the
legally required high-voltage test. The voltage to be used
corresponds to the peak value of the AC voltage required by
the standard.
