18.2. Functionality check

Check air pump condition – the air
pumps should be operating normally
without excessive vibration or noise.
Troubleshoot any problem or call in
service personnel if trouble is detected.

Check fan operation (visually) – the fans
must be running per the description of
their function. Troubleshoot any problem
or call in service personnel if trouble is
detected.

Check to ensure the power cord, the
cable for the pressure sensor on the air
tank and the connecting compressed air
hoses
are undamaged. Replace
damaged components or call in service
personnel.

Check the ambient temperature on the
display – the ambient temperature must
be below the temperature limit (40
o
C).
Cool the space if the temperature is
high.

Check for alarm conditions on the
display – troubleshoot and remedy all
alarms.
18.3. Leak check compressed air
connections and inspect the
equipment
Leak testing:

Leak test the compressor’s compressed
air lines when running – when the
compressor is delivering pressure (not
during regeneration blowdown).

Use a leak analyser or soapy water to
check all joints and connections for
leaks. Tighten or reseal the connection
where leaks are found
.
Inspecting the equipment:

Check the condition of the compressor
air pump for normal operation and noise
levels.

Check the operation of fans.

Check the condition of filters.

Check the condition of the air pump
itself:
- contamination in the crankcase and
play in the crankshaft

Replace any parts as needed.
18.4. Inspection of electrical
connections
Inspect the product’s electrical
connections when the mains are
disconnected!
Inspection

Check the mechanical function of the
main switch Q10 and the START-STOP
buttons, S1 and S2.

Check the power cord, conductors
connected to the X1 terminal strip and
the main switch to ensure they are
undamaged. Inspect to ensure the
connection terminals are properly
supported to relieve tension.

Check to ensure all screw terminals on
all conductors are tight (motor circuit
breakers Q1 to Q6, mains circuit
breakers F1 to F3, contactors Q11 to
Q16 and Q20 to Q21, etc.) Tighten all
loose conductors with a screwdriver.

Visually inspect the connection of
individual cables to the terminal strip X1
(spring clips) and the LOGO! control
system (screw terminals).

Inspect all screw terminals for the
protective green and yellow PE
grounding conductor in the electrical
box, the motor section, the cooling unit
and the pressure vessel. Tighten any
loose terminals.

Inspect the connector X50 (dryer and
cooler) and the pressure sensor (B1) (on
the pressure vessel).
18.5. Air pumps intake filter set
replacement
(Fig. 18)
The filters installed in the
compressor air pump crankcases
must be replaced during regular
operation of the compressor.
