Operating pressure:   

Actuating part: 0.1 

– 1.0MPa   

Braking par t: 0.3 

– 0.5MPa 

Fluid & ambient temperature: 5 to 60

2. 

Use clean air. 

Do  not  use  the  product  with  compressed  air 
includes 

chemicals, 

synthetic 

materials 

(including  organic  solvents),  salinity,  corrosive 
gases,  etc.,  as  this  may  cause  damage  or 
malfunction.

 

Caution

 

1.  Install air filter. 

Install air filter before and in  vicinity of  valve.  The 
filter  should  be  able  to  collect  particles  of  5 
microns  or  smaller.  A  large  quantity  of  drain  may 
cause malfunction of pneumatic components. 

2.  Install after cooler, air dryer, auto drain, etc. 

Compressed 

air 

that 

includes 

excessive 

condensate  may  cause  malfunction  of  valve  and 
other  pneumatic  equipment.  To  prevent  this, 
install after cooler, air dryer, auto  drain, etc. 

 

Pneumatic circuit

 

Warning

 

1. 

Be  certain  to  use  a  pneumatic  circuit  which  will 

apply  balanced  pressure  t o  both  sides  of  t he 
piston  when  in  a  locked  stop.  (Refer  to  Chapter  6 
for recommended pneumatic circuit.)   

      In  order  to  prevent  the  cylinder  lurching  after  a 

locked  stop,  use  a  circuit  which  applies  balanced 
pressure to both sides of the piston when restarting 
or  when  manually  releasing  the  lock,  thereby 
canceling  the  force  generated  by  the  load  in  the 
direction of piston movement.

 

 

2. 

Use  a  solenoid  valve  for  unlocking  which  has  a 

larger  effective  area,  as  a  rule  50%  or  more  of 
the  effective  area  of  the  cylinder  drive  solenoid 
valve.   

          (Refer  to  Chapter  6  for  recommended 

pneumatic components.) 

The  larger  the  effective  area  is,  the  shorter 

the  locking  time  will  be,  and  stopping 
accuracy will be improved. 

 

 

3. 

Place  the  solenoid  for  unlocking  close  to  the 

cylinder,  and  no  farther  than  the  cylinder  drive 
solenoid  valve.   

The  shorter  the  distance  from  the  cylinder,  the 
shorter  the  overrun  amount  will  be,  and  stopping 
accuracy will be improved.   

 

4. 

Allow  at  least  0.5  seconds  from  a  locked  stop 

(intermediate  stop  of  the  cylinder)  until  release  of 
the lock.   

When  the  locked  stop  time  is  too  short,  the 
piston rod may lurch  at a speed  gr eater than the 
control speed of the speed cont roller.   

5. 

When  restarting,  control  the  switching  signal  for 

the unlocking solenoid  valve so that it acts before 
or at the same time as the cylinder drive solenoid 
valve.   

If  the signal  is  delayed,  the  piston  rod  may  lurch  at 
a  speed  greater  than  the  control  speed  of  the 
speed controller.   

 

Installation 

Warning

 

1. 

Connect the slider end and the load  with the lock   

released.

   

2.  Ensure  that  the  equipment  operates  properly 

before the use. 

3. Operation manual

 

Do  not  install  the  products  unless  the  safety 
instruction have  been read and understood. 
Keep  this  operation  manual  on  file  for  future 
reference.  

Caution

 

1.  Maintenance space 

When  installing  the  products,  allow  space  for 
maintenance.  

2.  Do  not  give  strong  impact  and/or  excessive 

moment when work is mounted. 

External force ot her than allowable moment may 

cause  rattle  at  guide  part  and/or  increase  in 
sliding resistance.  

5.   

Be  careful  to  avoid  scratches  or  dents,  etc.  on 

the sliding sections of the slider.
