FAILURE POSSIBLE CAUSE REMEDY
None of the compressor
air pumps starts
Problem with electrical power source Main breaker is off
Loss of power
Check mains voltage
Loose terminal in the electrical box - tighten
Check the main power connection - replace if damaged
Failed pressure switch
Inspect the terminals and operation of the pressure
switch - replace if damaged
Some compressor air
pumps do not start
(indicators are on)
Loss of power to motor
Check mains voltage
Check function of contactor and thermal relay - replace
if damaged
Loose terminal on motor terminal strip - tighten
terminals, replace damaged or broken terminals
Motor winding shorted, damaged /open
thermal protection/ high ambient
temperature
Replace the motor / decrease the ambient temperature
Worn piston or other moving component
(mechanical damage to moving
components)
Replace damaged parts
Controller malfunction
Check the functionality of the controller and software –
replace if damaged or reload the program
RUN / STOP indicator
does not light up green
Open connection between controller and
expansion module
Check the connection and replace if damaged
Loss of power
Check mains voltage
Loose terminal in the electrical box - tighten
Check the main power connection - replace if damaged
Problem with electrical power source Main breaker is off
Controller or expansion module
malfunction
Replace the malfunctioning controller or module
Compressor air pumps
switch frequently, even
with no compressed air
demand
Air leak in compressed air distribution
system Check compressed air distribution system – tighten the
leaking connection
Check valve leaking Test check valves and clean – replace if damaged
Solenoid valves leaking after
regeneration
Clean the check valve – replace if damaged
Leak at pressure sensor and safety
valve
Check functionality and clean – replace if damaged
Functionality of certain
compressor air pumps
is reduced, run cycles
are extended
Leak at compressor air pump
Check the compressor air pump for leaks – tighten the
leaking connection
Worn piston rings Replace worn piston
Gasket between cylinder head and
valve plate damaged
Replace the gasket, tighten
Intake filter is plugged Replace old filter with a new filter
Certain compressor air
pumps are noisy
(knocking or metal-on-
metal sounds)
Damaged motor bearing Replace damaged bearing
Damaged piston bearing, piston rod Replace the damaged piston
Failed (cracked) rubber mount spring Replace damaged spring with new spring
High ambient air
temperature when
compressors on top of
Insufficient ventilation in compressor
space
Secure suitable conditions
Compressor air pump, cooler and Replace the defective fan(s)
