SYMPTOM

PROBABLE  CAUSE

SOLUTION

Piston  suddenly  floating  or 
descend.

Piston  and  Cylinder 
contaminated.

Disassemble  P/C  module  to 
cleaning.

Piston  does  not  rotate.

1.  Piston  position  is  fully   
floating  or  in  the  bottom.

2.  Motor  trouble  or 
disconnected  belt.

1.  Pressurized  or  reduce  pressure 
to  make  correct  piston  position.

2.  Replace  motor  or  belt.

Piston  dropped  very 
quickly.

Internal  or  external  leaks.

Find  the  leaks  point  then  tighten 
or  change  the  fitting  to  remove 
the  leaks.

Piston  does  not  float.

Damaged  Pressure 
generator/controller  O-ring. 

Replace  Pressure 
generator/controller  O-ring.

3.  Trouble  Shooting

3.1.  Overview

PDPG  has  precision  machining  technology  and  high  electronic  engineering  technology 

therefore,  it  need  to  handle  carefully. 

Parts  of  the  defect  and  the  damage  can  lead  to  unexpected  and  dangerous  results. 

User  needs  to  get  training  from  who  is  well-acquainted  with  operation  of  PDPG 

system.
