Changes:
The digital indicator type D122 can also be manufactured according to the examination
protocol, listed in the associated examination certificate. The change concerns the
enlargement around the types D122.PA.7.0.3K and D122.FF.7.0.3K for the binding to
intrinsically safe field busses Profibus PA respectively FF.H1 as a three channel indicator.
The application of the supplemental types can occur in explosion-threatened areas, which
requires devices of the category 2. By the application in areas of explosion-threatened by
dust, the at most allowed ambient temperature is +65°C.
The information to the allowed ambient temperature is valid consistently accordingly of the
second supplement also for the supplemental types.
The electric data of the second supplement are changed as follows or complemented:
Electric data of the types D122. PA.7.0.0, D122.FF 7.0.0, D122. PA.7.0.3K and
D122.FF.7.0.3K:
