22.2.  Check of product operation 

  Check  air  pump  condition 

–  the 

aggregates 

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 
aggregates 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. 

22.3.  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. 

22.4.  Inspection of electrical 

connections 

 

Risk of electric shock. 

Inspect  the  product’s  electrical 
connections  when  the  mains 
are disconnected.

 

  Check  the  mechanical  operation  of 

main circuit breaker FA13. 

  Check  the  power  cord,  conductors 

connected to the X1 terminal strip and 
the  main  circuit  breaker  FA13  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  FA1-6,  contactors 
KM1-6,  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. 

22.5.  Condenste drain 

 

A  wet  floor  resulting  from 
overflow from the vessel poses 
a slip hazard. 

Regularly 

empty 

the 

condensate collection vessel.

 

 

Switch  off  the  compressor 
every time before emptying the 
vessel!
