System Overview
Major Hardware Components
Power Distribution Panel
A Power Distribution Panel is mounted inside the Process analyzer enclosure on the left side of
enclusore, magnet side. This unit contains all the circuit breakers for the system except the purge
system and interlocks transformer..
The Lab Analyzer Distribution pane l is placed on the front panel and includes also the main power
switch of the analyzer
Interlocks
The purpose of the Interlocks is to completely isolate the any non explosion proof certified equipment
contained NMR system when the system is shut down, either by the purge system or power outage.
Lab Analyzer does not contain an Interlock mechanism
ENCLOSURE ENVIRONMENTAL CONTROLS
The environmental controls for the analyzer enclosure consist primarily of temperature controls, as
described in this section. Purity of the atmosphere within the cabinet is a function of the air supply.
Temperature Controls
As mentioned previously, temperature control of the magnet and its environment are very important
for good performance of the analyzer system. Therefore, separate controls and separate air
conditioners are provided for the two cabinet enclosures, as described below.
Magnet Cabinet
There are 3 air conditioners for both compartments. These solid state air conditioners provide cooling
as well as heat. The air conditioners run continuously — temperature is controlled by an RTD
mounted on the wall of the compartment, which is used as the measurement input to a PID
temperature indicating controller, mounted in the electronics rack in the electronics side of the
enclosure..
The Lab Analyzer is controlling the temperature inside the Magnet enclosure only with a PID loop
based on the heater card. It is not displayed at the Heater Diagnostic tool. The temperature inside the
Lab Analyzer is measured with an external PID thermocouple
The Lab analyzer has only one A\C unit mounted on the left side wall.
