All components of analyzers or analyzer modules are incorporated into a 1/1 19" housing.
The housings are available as rack mounting (R) or as table-top (T) versions. For analyzer modules
there is mounted a blind plate instead of an operation front panel.
These analyzers need DC 24 V power supply utilizing an external power supply unit. They provide
a three pole power input connector located at the rear panel.
It is recommended to use original Emerson Process Management power
supply units and supply cords. If a supplement is used take care of correct
pin assignment, as given on the analyzer´s rear panel!
The analyzers do not provide a power switch and are operable when con-
nected to power.
For analyzer module (A) [external installation or platform mounting] it is
not allowed to supply the module from front and rear simultaneously !
For external installation connections on frontside absolutely have to closed
with the blind plate delivered from our factory to be in agreement with the
CE conformity.!
Output signals and data are accessible at the rear panel via submin-d connectors. Depending on
analzyer variation not all signals are available. For information about pin-assignments see section
21.
