18.2. Check of product operation
•
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.
•
Visually inspect fan operation
– the
fans must be operating when the air
pumps are running. 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 at the
display
– the ambient temperature
must be below the temperature limit
(40°C). Cool the space if the
temperature is high.
•
Check for alarm conditions on the
display
– troubleshoot and remedy all
alarms.
18.3. Check the compressed air
connections for leaks and inspect
the equipment
Leak testing
•
Check the compressor's compressed
air lines for leaks during operation
–
pressure supplied by the compressor.
•
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.
•
Fan operation check
– the fans must
be running during the defined
compressor work cycles.
•
Check the filter condition
– clean dirty
filters or replace with new filters.
•
Check the solenoid valves in the valve
module.
•
Check the operation of the automatic
condensate drain.
•
Call in service personnel if a
malfunction is suspected.
18.4. Inspection of electrical
connections
Risk of electric shock.
Inspect the product’s electrical
connections when the mains are
disconnected.
•
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 threaded
conductor terminals are tight (on
motor circuit breakers Q1-9, circuit
protection devices F1-3, contactors
Q11-19, etc.). Tighten all loose
terminals 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
conductors in the
switchboard, 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)
(in the pressure vessel).
18.5. Condensate drain
A wet floor resulting from
overflow from the vessel poses a
slip hazard.
