Troubleshooting
GENERAL
As mentioned in the section dedicated to protections,
the command and control board controls the smooth
operation of the compressor.
It is possible that, due to the incorrect use of the
machine, or incorrect maintenance or unforeseen
conditions, etc., malfunctions occur and that only their
effects are indicated.
The table below aims at helping the operator solve
some difficulties should they arise while indicating their
possible causes.
pRObLEM - CAUSE - SOLUTION
Below some possible failures are indicated with their
causes and how to identify the correct solution.
PROBLEM
CAUSE
SOLUTION
A. Start
Maestro
XB
works, start is allowed
but the star/triangle admission
commutation or start Inverter does
not take function correctly.
The power supply line is insufficient
and the excessive drop of voltage
following the start provokes the
contactors or the Inverter safety relay
(
i
version) to be released.
Check for the correct size of the supply
line. Please refer to the
“Installation,
Use and Maintenance Manual”
in
Section 5.
Contact the nearest
authorized service center.
Maestro
XB
works, it enables the start,
but the compressor does not start.
Pressure inside the compressor is
higher than the maximum tolerated
value for the start: or for an abnormal
return of the network air, or because
the pressure transducer reads an
incorrect value.
Check the inner pressure on the
pressure gauge of the separator and
compare it with the value given by
Maestro
XB
. Verify the correct operation
of the pressure detection system:
transducer, collector and switching
solenoid valves. Contact the nearest
authorized service center.
The hour programming has been
enabled.
The compressor runs within a network
with other compressors.
B. Pressure
The network pressure does not reach
the required value.
The servo valve has not been correctly
gauged.
Verify the setting. Contact the nearest
authorized service center.
The unload solenoid valve is blocked
in the open position.
Replace the solenoid valve. Contact
the nearest authorized service center.
The minimum pressure valve does not
function correctly.
Verify the operation.
Contact the nearest authorized service
center.
Suction filter clogged.
Replace the filter. Please refer to the
“Installation, Use and Maintenance
Manual”
, Section 9.
Request for air greater than the
compressor maximum capacity.
Please refer to the Sales Organization
of Ing. Enea Mattei S.p.A. to study
equipment improvement.
The inner pressure exceeds the set
value.
The servo valve has not been gauged
correctly and/or the setting of the
maximum pressure value in the [USER
MENU] menu is incorrect.
Verify both the servo valve and
the correct setting of operating
parameters. Please refer to the
“Installation, Use and Maintenance
Manual”
, Section 6 and 8.
