Planning of the ETH Electro Cylinder for EX-Environment

The internal end stops of the electro cylinder may under no circumstances be
accessed during operation. The internal end positions may only be accessed by
the cylinder in setup mode and only for determining the end positions resp. for
relubrication with a low force of a few N (torque limitation if possible below 10 %)
and very slowly (max. 2 % of the nominal speed).
The lifetime of the electro cylinder depends strongly on the degree of power
exploitation and on impermissible operating states occurring - even if only for a
short time.
Depending on the operating conditions (rotation speed, load, etc.) increased
surface temperature in the area of the drive may occur. When touching it during
operation slight injuries from burning may occur. Don't touch the product during
operation. At maintenance, service and repair always take care that the product is
cooled off before starting work.

1.
Operator
Check der Basic conditions for ATEX
Please check by means of this document whether the basic
conditions for the use of the ETH Electro Cylinder in explosive
environment are possible.
ETH ATEX: Basic conditions for the
use, chapter 1 to 3
Part No.: 192-550006

Planning of the ETH - Electro Cylinder
Please plan and design the ETH - Electro Cylinder for your
application by means of the ETH product catalogue
ETH Product Catalogue
Part No.: 192-550003
3.
Operator
Check the heating of the ETH Electro Cylinder
Determine your ATEX application data and check by means of the
Force Velocity Diagram (ETH032, ETH050 and ETH080 only) if
the heating of the selected ETH Electro Cylinder is within the
accepted range of the required data application (if so, continue
with 5.) For ETH100 and ETH125 an application specific approval
is necessary (continue with 4.2)

Operator
Adaption of the ETH Electro Cylinder or of the application
data
In case the heating of the selected ETH with the required
application data is outside the permitted area you can continue as
follows:
4.1
Operator
- Select larger ETH Electro Cylinder (size of cylinder, Pitch),
- Reduce the application data (Force, Speed or Duty cycle)
or
4.2
Parker / User
- Ask for a application specific release
5.
Operator
Ordering the ETH Electro Cylinder with ATEX Option
If the heating of the ETH Electro Cylinder is within the permissible
are of the F-v-Diagram (a) or if an application specific release (b)
from Parker Hannifin is necessary, the selected ETH can be used
within the ATEX application described.
a) standard ATEX Cylinder, A No.: 000
b) application specific ATEX release, A-No.:xxx
