Frequency converter
This short section gives you the key information about the
operation of the frequency converter. (For more information
see the detailed and enclosed manual of the converter
manufacturer)
The frequency converter allows continuous operation of
the motor, thus enabling production of compressed air to be
adjusted according to need.
The rotational speed varies between just over 30 and 100% of
the compressor motor speed.
The frequency converter is configured and parameterized at
the factory.
Should an error occur, the compressor is switched off and the
message “Error Converter” appears on the display of the
RENNERtronic control system. Also observe the fault
messages on the display of the frequency converter. Check the
causes and measures in the corresponding chapter of the
operating instructions of the frequency inverter (see addendum
to the operating instructions for compressors with frequency
converter)
CAUTION
Make sure that the air circulation is not restricted or blocked in
any way. A sufficient clearance area must be provided between
the ventilation grid and the walls of the room.
