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.
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 interrupti-
on, the time measurement begins again
until deactivation. Check whether motor
can rotate freely. Check whether fan is
propelled backwards by airflow (beha-
viour during rotation by airflow in back-
wards direction).

Mains voltage too low
If the intermediate circuit voltage falls below
the set limit value, the unit is deactivated.
If the mains voltage increases above the
limit value again within 75 sec., the unit
is automatically restarted. If the mains
voltage stays below the limit value for
longer than 75 sec., the unit is deactiva-
ted with an error message

Mains voltage too high
Cause – input voltage too high.
If the mains voltage increases above the set li-
mit value, the motor is deactivated.
If the mains voltage falls below the limit
value again within 75 sec., the unit is au-
tomatically restarted. If the mains voltage
stays above the limit value for longer
than 75 sec., the unit is deactivated with
an error message.

Peak current error
If the motor current (even transient) increases
above a set limit value, the unit is deactivated.
After deactivation, the controller waits for
a period of 5 sec. and then restarts the
unit again. If there are 5 further deactiva-
tions within 60 sec., the unit is deactiva-
ted definitively with an error message. If
60 sec. pass without another deactivati-
on, the counter is reset.
