BLADE 1-2-3
General
The table below aims at helping the operator
face, identify and solve some diculties
should they arise during the operative life of
the machine.
Problem - Cause - Solution
Below some possible failures are indicated
with their causes and how to identify the
correct solution.
PROBLEM CAUSE SOLUTION
A. Starting
The compressor does not start. The electrical supply is not
sucient and the excessive
voltage drop during the
starting causes release of the
contactor.
Check correct sizing of the
electrical supply.
The line pressure is higher than
Pmax.
Check the line pressure.
The pressure switch reads a
wrong value.
Check proper operation of the
pressure switch.
Contact the nearest authorised
service centre.
B. Pressure
The system pressure does not
reach the required value.
The minimum pressure valve
does not operate properly.
Verify the operation.
Contact the nearest authorized
service center.
Clogged intake lter. Replace the lter (section 7-3).
Higher air demand than
compressor’s maximum
capacity.
Please contact Ing. Enea Mattei
SpA or a distributor to study an
improvement of the plant.
Clogged separating lter. Replace the lter and verify the
causes of clogging.
The system pressure does not
reach the required value and
the anti-condensate valve is
operating.
The unit has not reached the
correct internal temperature
Allow the compressor to run and
build up its internal temperature.
C. Oil
Excessive oil consumption; the
level lowers too quickly; oil is
detected inside the system.
The oil return valve is clogged. Replace the valve and verify the
causes of clogging. ( See
Section 7.03).
Clogged separating lter. Replace the lter and verify the
causes of clogging.
D. Temperature
The compressor stops due to
overheating.
The ambient temperature is too
high for compressor operation.
Verify the cause and eliminate
the problem.
The compressor stops due to
motor overheating.
Excessive working pressure. Check setting and bring it to the
machine’s setting value.
The motor cooling is not
sucient; there is not enough
air or it is too hot.
Verify the ambient conditions.
