Warning
•
This product is designed for pneumatic devices.
The applicability of pneumatic equipment to the intended system
should be judged by the pneumatic system designer or the personnel
who determined specifications for such system.
•
Since the operating conditions
for the products contained in this instruction are diversified, the
applicability of pneumatic equipment to the intended system should be
determined by the pneumatic system designer or the personnel who
determined specifications for such system. Before making a system,
the system designer should thoroughly examine all specifications for
such a system and also take into consideration the possibility of any
trouble with the equipment.
•
The pneumatic equipment should only be handled by
persons who have sufficient knowledge and rich
experience
Improper handling of compressed air will result in danger. Assembling,
operation and maintenance of machinery using pneumatic equipment
should be performed by persons who have sufficient knowledge and
rich experience.
•
Never operate machinery nor remove the equipment
until safety is assured.
Before checking or servicing machinery and equipment, be sure to
check that steps for prevention of dropping or runaway of the driven
component have been completely taken.
When removing the equipment, make sure that the above-mentioned
safety measures have been done beforehand.
Then turn off air supply and power to the system and purge
compressed air in the system.
When restarting machinery and equipment, check that proper prevention
of malfunction has been provided for and then restart carefully.
•
When using the pneumatic equipment in the following
conditions or environments,
take the proper safety measures and consult Parker before hand.
Manual / Air Saver Unit -
ASV2000, 5000, 13000, 15000 Series
•
Conditions and environments (other than specified) and
outdoor use.
Applications to nuclear power equipment, railroads, aircraft, vehicles,
medical equipment, equipment connected with food and drink,
amusement facilities and safety devices such as emergency
interruption devices, clutch/brake circuits for a press and the likes.
Applications which require extreme safety and will also greatly affect
human and property.
1) After piping to Air Saver Unit and while the supply air is shut off, fully
close the ON time adjustment needle (clockwise rotation) and fully
loosen the OFF time adjustment needle (counter clockwise rotation).
Please use the dots for position indication of ON/OFF adjustment.
2) Turn on air to the supply port, air should pass to the output port
continuously.
3) Slowly loosen the ON time adjustment needle in CCW direction.
A pulsed air blow with short OFF time will start. It is suggested
to stop rotating the ON time adjustment needle at around 3 turns
(for ASV2000), 2 turns (for ASV5000), or 1.5 turns (for ASV13000
&15000) in CCW direction.
4) ASV2000&ASV5000:
Next, adjust the OFF time by slowly tightening the OFF time adjustment
needle in CW direction.
The OFF time of the pulsed air blow will get longer.
It is suggested to stop rotating the OFF time adjustment needle at
around 7 turns (for ASV2000 or 5 turns (for ASV5000).
This should result in about 50%
ON/OFF duty of pulsed air blow at 1.5Hz (ASV2000) or 2Hz(ASV5000).
ASV13000&15000:
Close OFF time adjustment needle fully by screwing the needle in CW
direction. Then, slowly loosen about 2 turns in CCW direction.
This should result in about 1Hz and 50% duty pulsed air blow.
5) Use the procedure of 4) as a starting point, and make the frequency
and duty adjustments required in your application by using the ON time
and OFF time adjustment needles.
6) Fix the adjustment position by tightening lock nuts on adjustment
screws.
Regarding repair and maintenance, please consult Parker.

* Adjust frequency of pulsed air to less than 5Hz (ASV2000&ASV5000),
0.1~1Hz (ASV13000&15000). If frequency of pulsed air is higher than
5 Hz (ASV2000&ASV5000), 1Hz (ASV13000&ASV15000),
operation of the pneumatic circuit (logistic element) may become
unstable.
Attention
•
Be sure to cut air supply to Air Saver Unit when air blow is not used.
Blown air may come out even if the ON/OFF time adjustment needles
are fully tightened.
This unit is not designed to be an "OFF" valve.
