Cause /
>> Explanation
Motor start error
If a start command is present (enabled and set
value > 0) and the motor does not begin rota-
ting in the right direction within 5 minutes, an
error message is issued.
Mains voltage too low
If the intermediate circuit voltage falls below the
set limit value, the unit is deactivated.
Mains voltage too high
Cause – input voltage too high.
If the mains voltage increases above the set
limit value, the motor is deactivated.
Peak current error
If the motor current (even transient) increases
above a set limit value, the unit is deactivated.
Temperature alarm
The max. permissible internal temperature is
exceeded.

Controller response /
>> Repair
If it is possible to start the motor in the
set rotation direction after the error mes-
sage, the error message disappears.
After an intermediate voltage interruption,
the time measurement begins again until
deactivation. Check whether motor can
rotate freely. Check whether fan is pro-
pelled backwards by airflow (behaviour
during rotation by airflow in backwards
direction).
If the mains voltage increases above the
limit value again within 75 sec., the unit is
automatically restarted. If the mains vol-
tage stays below the limit value for longer
than 75 sec., the unit is deactivated with
an error message.
If the mains voltage falls below the limit
value again within 75 sec., the unit is
automatically restarted. If the mains vol-
tage stays above the limit value for longer
than 75 sec., the unit is deactivated with
an error message.
After deactivation, the controller waits for
a period of 5 sec. and then restarts the
unit again. After 5 deactivations within 60
sec. the unit is deactivated definitively.
Otherwise the counter is reset.
