NOTICE
Improper assembly of manifolds to traditional flange can damage SuperModule
For safe assembly of manifold to traditional flange, bolts must break back plane of flange web (also called bolt
hole) but must not contact sensor module housing.
SuperModule and electronics housing must have equivalent approval labeling in order to maintain hazardous
location approvals.
When upgrading, verify SuperModule and electronics housing certifications are equivalent. Differences in
temperature class ratings may exist, in which case the complete assembly takes the lowest of the individual
component temperature classes (for example, a T4/T5 rated electronics housing assembled to a T4 rated
SuperModule is a T4 rated transmitter.)
Severe changes in the electrical loop may inhibit HART
Therefore, Emerson cannot absolutely warrant or guarantee that the correct failure alarm level (
can be read by the host system at the time of annunciation.
