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.
