TROUBLESHOOTING

Before proceeding, depressurize the air tank to zero and disconnect the device
from the mains.
The equipment, in particular the cooling fan, must be kept clean to ensure the long-term
efficiency of the cooler – the cooling fins must be cleaned occasionally to remove any dust.
Troubleshooting can be performed only by qualified personnel.
To follow the rules of personal hygiene for works with contaminated material.To
separate, label, packing and providing for decontamination of contaminated parts
by course of national regulations.
MALFUNCTIONS
Compressor does not
start
Compressor often
switches on

running,
or is running
irregularly
NP-DUO-13_11-2021-MD
POSSIBLE CAUSE
No voltage at the pressure switch
Motor winding failure, damaged
thermal overload protection
Faulty capacitor
Seized piston or other rotating part
Pressure switch does not switch
Air leak in compressed air distribution
system
Leaking non-return valve
Large volume of condensed liquid in
pressure vessel
Low compressor performance
High air usage by device, Leak from
pneumatic distribution system, Low air
pump output
Air pumpmalfunction
Dryer malfunction
Leak from pneumatic distribution system
Worn piston ring
Inlet filter is plugged
Defective solenoid valve
Damaged piston bearing, piston rod,
motor bearing
Loose or cracked spring
No voltage at the suction unit terminals
Other mechanical defect in suction unit
Check voltage in socket
Check the breaker switch - and switch to
the "I" on position
Loose conductor at terminal – tighten
Check the electrical cord – replace
defective cord
Replace motor or windings
Replace capacitor
Replace damaged parts
Check the function of the pressure switch
Check compressed air distribution
system – seal loose joints
Clean non-return valve, replace seals,
replace non-return valve
Drain condensed liquid
Check the time to fill the air tank
Decrease air consumption
Use compressor with higher capacity
Check pneumatic system – seal loose
connections
Clean / replace the pump
Clean / replace the pump
Replace dryer
Check compressed air distribution
system – seal loose joint
Replace worn piston ring
Replace old filter with a new filter
Repair or change the valve or coil
Replace damaged bearing
Replace damaged spring
Check voltage in socket
Check the fuses - replace faulty fuse
Loose terminal - tighten
Check the electrical cord - replace
defective cord
Check for control voltage
Damaged bearing, damaged suction unit
impeller - call a service centre
