Preface
These Operating Instructions contain all aspects relevant to explosion protection for the
ET-xx6-A-* HMI devices (SERIES 300 Operator Interfaces
– EAGLE, SERIES 400 Open HMI –
Panel PC´s and SERIES 500 Thin Clients). They also contain information on the connection and
installation of these devices.
These Operating Instructions contain a joint description of all three product lines: Operator
Interfaces, Panel PC´s and Thin Clients. Any differences between the three product lines will be
explicitly mentioned and dealt with. As a rule, though, the information contained in these
Operating Instructions applies to all models of the ET-xx6-A-* series.
The ET-xx6-A-* HMI devices with display sizes of 26 cm / 10.4", 38 cm / 15" and 48 cm / 19" will
be available in Hardware Revision 3.
All data relevant to explosion protection from the EC-type examination
certificate were copied into these operating instructions.
For the correct operation of all associated components please note,
in addition to these operating instructions, all other operating
instructions enclosed in this delivery as well as the operating
instructions of the additional equipment to be connected !
Please note that all certificates of the HMI devices can be
found in a separate document (CE_ET-xx6-A).
You can find this document in the internet at
or request it from R. STAHL HMI Systems
GmbH.

Device function
The ET-xx6-A-* HMI devices are explosion-proof equipment for installation in hazardous areas
and can be installed in zones 1, 2, 21 and 22 according to ATEX directive.
All devices have a modular structure, which makes changes and maintenance easy. They can be
integrated into control cabinets or panels, etc.
2.1
Image sticking
Continuous displaying fixed pattern may include image sticking. It’s recommended to use screen
saver or moving content periodically if fixed pattern is displayed on the screen.
2.2
Processor types
All devices are fitted with modern, powerful processors. Depending on the type of application,
different processor types are used for the HMI devices (see Technical Data).
Starting in 2016, a new Intel® Atom™ processor type of the Bay Trail (BT / BS) platform will
gradually replace all previous processor types in the HMI devices. This new processor type
processes data four times as fast as the previous processors.
2.3
Activation pressure touchscreen
To prevent damage to the touchscreen, activation pressure on the screen must be very low (0.1
to max. 1 N).
