6 COMPRESSOR MAINTENANCE
Anomalies
The machine stops, as the oil
alarm has triggered (red
LED).
Cause
Excessive temperature of air/
oil mix outlet from the screw
(105 °C).
Solution
Check the oil level. Check if the radiator is
clean. Check if the dust removal pre-filter is
clean. Check the ambient temperature and
the minimum distance of the compressor
from the walls in the room. Check if the
mobile soundproof panels are firmly secured
in place (pressurisation of the ventilation
air).
Ambient temperature too high, air discharge
channels too narrow or too long. Check oil
level and if the type of oil is correct. Check
if the oil filter is clogged.
To start the machine again, open the front
panel of the compressor, press the reset
key on the right side of the electrical system
(see button 1 point 5.2.2) and the RESET
key of the board, then press START.
6.1.11 Cleaning the dissipator (only for version SD)
Dust transported by the cooling air may settle on the fins of the dissipator. If the dissipator is not cleaned
regularly, the drive may encounter alarms and faults due to overheating. In “normal” surroundings, the
dissipator must be cleaned and inspected on a yearly basis, but more often in dusty surroundings.
Clean the dissipator as follows:
Remove the cooling fan.
Blow DRY compressed air from the bottom upwards and simultaneously use a vacuum cleaner on the air
outlet to clean away the dust.
Cover any equipment nearby with sheets to protect them against the
dust expelled.
Re-install the cooling fan.
6.2 Diagnosing the alarm status/inconveniences-faults
Before doing any job on the compressor ensure that:
• The main ON/OFF switch is turned Off (position “0”)
• The electric compressor switch is disabled in position “0”
• The compressor is shut-off from the compressed air system
• The compressor and the internal pneumatic circuit are completely de-pressurised
If you are unable to rectify the anomaly encountered on your compressor contact your nearest Authorised
service Centre.
