. Troubleshooting

 

If the product fails in any way, perform the following troubleshooting measures. 

 
 

 

 

Failure phenomenon 

 

Possible causes 

 

Countermeasures 

 

 

 

 

 

Vacuum 

absorption 

failure 

Vacuum is not generated 

 

Clogging by foreign matter or particles 

 

  See (1) and (2) 

Vacuum pressure 
decreased 

 

Supply valve does not 
operate 

Decline  in  the 
power  supply   
voltage 

 

  See (3) and (4) 

 

Electrical  wire   
failure 

 

  See (4) and (5) 

 

The  supply  pre
ssure  exceeds   
the  operating   
pressure  range. 

 

  See (6) 

 

Entry of oil mist 

 

  See (14) 

 

Control failure 

Simultaneous 
energization 

 

  See (7) 

 

Leakage voltage   

  See (8) 

 

Incorrect 

assembly 

during maintenance 

Mounting  failure 
of the gasket 

 

  See (9) 

 

Insufficient supply pressure 

 

  See (6) and (10) 

 

 

 

 

Fluctuation of 

vacuum 

pressure 

Noise  is  generated  intermitt
ently  when  air  is  exhausted
  when  adsorbing    and   
vacuum  pressure  slightly   
fluctuates. 

 

Vibration of fluid when vacuum pressure 
is generated 

 

  See (11) 

 

 

 

 

 

 

Air leakage 

from vacuum 

port 

When  using  the  manifold  ty
pe,  air  flows  from  the  vacu
um  port  of  the  stopped  pro
duct.

 

 

Exhaust air flows to the vacuum port 

 

  See (12) 

 

 

 

 

 

 

Vacuum 

release failure 

Release air is not output 

 

Vacuum release flow adjusting needle is 
fully closed 

 

  See (13) 

 

Release valve does not operate 

 

  See (3), (4), (5), (6) 

and (14) 

Workpiece is not released 
smoothly. 

 

Adhesion of the workpiece and pad 

 

  See (15) 

Control failure 

Simultaneous 
energization 

  See (7) 

 

Leakage voltage   

  See (8) 

 

 

 

 

 

 

 

Operation 

failure of the 

energy saving 

switch 

Vacuum is not held. Supply 
valve chatters.
