Special conditions
• Before final installation, the operator needs to decide on the
use of the device, either
A) as a device with ‘Ex i’ intrinsically safe type of protection
or
B) as a device with ‘Ex d’ type of protection
and permanently mark the selected type of use on the name
plate. Specific conditions of the surrounding environment,
such as chemical corrosion, must be taken into account when
affixing the permanent mark. Only the manufacturer must
change the selected type of use following a re-examination
• Variants that, according to declarations, also meet the
requirements for the ‘intrinsically safe’ type of protection
may no longer be used as ‘intrinsically safe’ if they have been
previously used as a flameproof type of protection
• Secure cable entries against twisting and loosening by using
a (medium-strength) securing adhesive.
• 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.
• 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.
