1 Preface
These Operating Instructions contain all aspects relevant to explosion protection for the MT-xx7
devices - device platform MANTA - (SERIES 400 Open HMI - Panel PC´s, SERIES 500 Thin
Clients and SERIES 600 KVM Systems). They also contain information on the connection and
installation (etc.) of these devices.
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 also note that all certificates of the HMI devices
can be found in a separate document (CE_MT-xx7).
You can find this document in the internet at
r-stahl.com or request it from R. STAHL HMI Systems
GmbH.
For more information on the HMIs please also refer to the
Manual (available as online manual on
r-stahl.com ).
2 Device function
The MT-xx7 HMI devices are explosion-protected equipment for installation in hazardous areas
and can be operated in zones 2 and 22 with interfaces for zones 0/1/2 and 20/21/22.
The devices are connected to a communication system via the serial interfaces (RS-232,
Ethernet) located in their connection box at the rear. The connection box also contains the USB
interfaces for the connection of various peripheral devices. Furthermore, the interfaces for
keyboard, mouse, video and audio signals are also located here.
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 of 400 and 500 SERIES 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) platform will
gradually replace all previous processor types in the HMI devices, up from HW Revision
01.01.01. This new processor type processes data four times as fast as the previous
processors.
In addition to the Bay Trail (BT) processor, the Thin Client device MT-577 will be equipped with
an AMD GX processor in 2019, up from HW Revision 01.01.04.
2.3 Activation pressure touchscreen
To prevent damage to the touchscreen, activation pressure on the screen with polyester foil
must be very low (0.1 to max. 1 N) and on the screen with glass surface must be medium (1.8 to
max. 2.5 N) !
