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. System Operation UM SW50407.05 31
