5. INTEGRATED PROTECTIVE FEATURES
The integrated protective functions cause the motor to switch off
automatically in the event of the faults described in the table.
Fault
Rotor position detection error
Blocked rotor
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
Impeller not
Imbalance in rotating
running smoothly
parts
Motor not turning
Mechanical blockage
Line voltage faulty
Faulty connection
Operating instructions
Safety feature description/
function
An automatic restart follows.
; After the blockage is
removed, the motor restarts
automatically.
Possible remedy
Clean the device;
replace it if imbalance
persists after cleaning.
Make sure no
weight clips are
removed during
cleaning.
Switch off, isolate
from supply and
remove mechanical
blockage.
Check line voltage,
restore power
supply, apply control
signal.
Isolate from supply,
correct connection;
see connection
diagram.
Deficient cooling
Motor/electronics
overtemperature
Ambient temperature
too high
Impermissible point of
operation
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.
What to check How to check How often

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.
Reduce the ambient
temperature.
Reset by reducing
control input to 0.
Correct the operating
point. Let the device
cool down.
