1. DESIGN AND SELECTION
•
Supply only “compressed air”.
•
For compressed air, always use clean air that does not contain corrosive
gas.
•
Be sure to use non lubricated, filtrated dry air (equivalent to Class 1, 3,
2 – ISO 8571-3).
•
With a thorough understanding of compressed air characteristics, design
a pneumatic circuit.
・
Where instantaneous stop holding at emergency stop is required, the
same function as in the mechanical or hydraulic or electrical units cannot
be expected.
・
There arise pop-up, jet-out and leaking phenomena caused by
compressibility and expansibility, which are air characteristics.
•
Prior to use, always ensure that the product withstands the operating
environment.
・
The product cannot be used in corrosive gas, chemical liquid solvent,
water, water vapour (steam) and ozone atmosphere. When a product is
exposed to water droplets, oil or metallic powder, such as spatters and
chips, be sure to protect it.
・
No product can be used in the explosive gas atmosphere.
•
Always pay extra attention to the electric circuit during emergency stop,
and cylinder operation, etc. during power failure.
•
Attach a “pressure switch” and “residual pressure discharge valve” to
the compressed air inlet of the equipment.
・
The pressure switch controls operation so that it cannot be carried out
where the set pressure is not reached.
The residual pressure discharge valve discharges compressed air
remaining inside the pneumatic circuit, to prevent accidents caused by
pneumatic equipment operation due to residual pressure.
•
If the product is left as it is with the supply pressure when no power is
turned ON, the secondary side pressure may increase up to the supply
pressure.
If any concerns regarding safety; take proper safety measures in the
system; for example, use an extra valve on inlet or outlet.
•
Use the product correctly at the indicated working pressure range.
•
Note the maintenance conditions clearly in the equipment instruction
manual.
・
The functionality of the product may be significantly reduced, depending
on the operating condition, operating environment and maintenance
situation, thereby safety might not be secured. If this maintenance
work is conducted accurately and correctly, it is possible to maintain a
sufficient product functionality and performance.
•
Use a constant voltage power supply.
•
Check the leak current to avoid a malfunction caused by such leakage
from other control equipment.
・
The ER may show malfunction under the influence of leak current when
a programmable controller or the like is used.
In case of 24 V DC:
1.8mA or less
•
The response time is affected by the supply pressure and load capacity.
When stable response time is required, install an extra pressure
regulator before the Electro – Pneumatic pressure regulator Series ER.
