Special conditions
• Prior to final installation, the operator must decide how the
device is to be used, either:
– as a device with the 'intrinsically safe Ex i' type of
protection or
– as a device with 'Flameproof enclosure Ex d' type of
protection
The operator must permanently mark the selected type of
use on the name plate. Specific ambient conditions, such as
chemical corrosion, must be taken into account when
affixing the permanent mark.
Devices that also meet the requirements for the 'Intrinsic
safety Ex i' type of protection in accordance with a separate
declaration may no longer be operated as intrinsically safe if
they have been previously used in the 'flameproof enclosure
Ex d' type of protection.
• In the case of high torsional forces, the bearing sleeves must
be replaced due to wear on the shaft for the position pickoff
(significant control deviation).
• If the positioner is operated at an ambient temperature
above 60 °C (140 °F) or below −20 °C (−4 °F), make sure to
use cable entries and lines suited for an operating
temperature corresponding to the maximum ambient
temperature increased by 10 K or corresponding to the
minimum ambient temperature, respectively.
• The dimensions of the flameproof joint of this equipment
partly exceed the minimum values required by EN 60079-1 or
IEC 60079-1 and also partly down-scale the maximum
required values therein. All inquiries relating to dimensions
must be directed to the manufacturer
• Screws that comply with the minimum requirements of the
A2-70, A2-80 or 10.12 quality grades must be used to close
the flameproof enclosure.
