5.3.9 ALArm coDEs (AL5) 'Control panel internal malfunction'.
If the control panel has an internal malfunction, the display
shows the alarm code “AL5”. In this case the compressor
stops immediately regardless of status and it is not possible to
restart it. the code alarm will flash on the display, the yellow
led and the temperature led will be off. the alarm can be reset
by pushing the 'reset' button only when the problem is
resolved.
5.3.10 ALArm coDEs (AL6) 'Maintenance required'.
When the set maintenance hours have expired, the alarm
code “AL6” appears on the display, this message does not
affect the normal function of the compressor. the alarm code
flashes alternately with the text that normally appears on the
display depending on the function. the flashing continues
when the compressor is “off”. the alarm can be reset by
pushing the 'reset' button only when the maintenance
tasks have been performed.
IMPORTANT: Failure to maintain the compressor as
advised in these instructions will invalidate the warranty.
5.3.11 cHEcKInG Hours of comPrEssor oPErAtIon:
During the normal working of the compressor, regardless of
its status except under alarm condition, or when the display
shows the text “off”, the worked hours (loading hours + idle
running hours) can be displayed when the 'reset' button is
pushed for 4 seconds. subsequent pushes of the button will
cycle the display through four pages of information. the
worked hours are divided between two displays: the first one
shows the hours worked in units of thousands, the second
one the worked hours up to 999 (example: for worked hours
of 24563, the first display is 024, and the second display is
563). If the 'reset' button is pushed again after the second
display of the worked hours, the time (in hours) to
maintenance will appear, also displayed in 2 parts as
explained above, (example: hours to maintenance 1561, first
display is 001 and second display is 561) from this condition,
if the 'reset' button is pushed again, the display returns to
text “off” or the air-end temperature display. If, during the
cycle, the button is not pressed for 10 seconds the display
returns to the original message.

5.5.2. OIL LEvEL check the oil level as indicated in section 7
“compressor maintenance”.
5.5.3. dO NOT START THE COMPRESSOR WITH THE GUARdS

OR ELECTRICALLY POWEREd EQUIPMENT.
5.6. STARTING THE COMPRESSOR.
5.6.1. following a power cut the compressor will start only if the
stArt button is pressed.
Ventilation must occur as illustrated below.
5.6.2. It is of important that the compressor works with all the
panels firmly closed. the failed observance of these
and the following standards may lead to accidents that could
cause personal injury and serious damages to the compressor
or its equipment.
5.6.3. InItIAL stArt uP ProcEDurE
Before initially starting the compressor (or following extended
inoperative periods), start the machine intermittently by
pressing the stArt & stoP buttons on and off for 3 or
4 seconds. After this it is advisable to run the compressor for a
few minutes with the air outlet tap open. Gradually shut-off
the air tap and load to maximum pressure, checking if the
inputs on each phase of the power supply are within the limits
and also if the pressure switch trips. At this stage, when the
max pressure value is achieved, the pressure switch will initiate
idle running for 2 minutes. After this time, if there is no air
consumption, the compressor will stay in the stand-by condition.
Discharge the air from the tank until the starting pressure is
reached (2bar difference compared to maximum pressure).
shut-off the air outlet tap and wait for the pressure switch to
trip, which will shut-on the intake valve and close the internal
discharge.
