Operating instructions
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
Allow motor to cool
protector activated
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
Reduce the ambient
too high
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
Correct the operating
operation (e.g. back
point. Let the device
pressure too high)
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.
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.
