5.4.1.2 MLT 1, external installation and 1/2-19" Housing
MLT 1 analyzer module housing is available for platform mounting (built-in into a NGA platform)
or for external installation (type A).
The analyzer variation MLT 1 configured as tabletop analyzer (type T) provide a handle attached
to a front panel frame. The instrument is intended for horizontal or slightly angular (utilizing the
handle as support) orientation during operation.
Without front panel frame and handle the analyzers may be mounted into a rack (rack mount
version, type R). Four screws located at the front panel are used to fix the analyzer in the rack.
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.
