2 Operational TheoryThe digital printed circuit board (PCB) is a general purpose microcomputer usedto control all functions of the analyzer. The analog input PCB and the analog outputPCB plug directly into connectors located on the digital PCB. In addition to controllingthese analog PCBs, the digital board performs the following functions:1. Processes input from the control panel pushbuttons.2. Provides signals for the selectable alarms.3. Processes serial I/O functions (RS-232 data). The serial interface defaultand programmable parameters are listed in Table 2-2.Table 2-2. Default and Programmable ParametersDefaultsProgrammable Options1200 Baud 1200 Baud8 Bits 5, 6, 7, or 8 BitsNo ParityEven, Odd, or No Parity1 Stop Bit 1 or 2 Stop Bits4. Controls the LCD and the LED displays.LCD: This screen is a dot-matrix display located on the control module ofthe analyzer. It is the user interface for system operations. Itdisplays the menus and command options available for eachfunction.LED: This screen is a 7-segment display located on the front panel of theanalyzer, above the control module. It displays only the oxygenconcentration. It is large and bright to allow the operator to read itat a greater distance. A dimmer switch for this display is located onthe display PCB behind the front panel.The analyzer power supply module is a replaceable assembly containing fourpower supplies and five alarm relays. Electronic circuitry used to drive and interfacethe alarm relays to the output of the microcomputer is also located inside this module.Note: This power supply contains an International Power Entry Module. Thisfeature allows operation on any of four international voltage ranges:100V, 120V, 220V or 240V (50Hz or 60Hz). It also facilitates both NorthAmerican and European fusing arrangements. Programming this moduleis described in the installation section of this manual.2-8TELEDYNE ANALYTICAL INSTRUMENTS
Installation 3InstallationInstallation of the analyzer includes:1. Unpacking the system.2. Recognizing the necessary precautions when installing the system.3. Hooking up the sample/span gas and air supply to appropriate connections.4. Installing the Micro-Fuel Cell sensor(s).5. Hooking up electrical connections.6. Testing the system.3.1 Unpacking the AnalyzerThe analyzer is shipped with all the materials and special items you need to installand prepare the system for operation. Carefully unpack the analyzer and inspect it fordamage. Immediately report any damage to the shipping agent. Remove the packingslip and verify that you have received all the components listed in Table 3-1.Table 3-1.
