This Quickstart Guide should be used in conjunction with the Instruction Manual that shipped with your instrument. Only necessary features to get you operational are discussed in this guide. Many of the advanced features of this analyzer are not described here so you should refer to the Instruction Manual to get the most from your analyzer Front Panel (Operator Interface) Take a minute to familiarize yourself with the analyzer’s interface. The standard 3000TAEU is housed in a rugged metal case with all controls and displays accessible from the front panel. The operator interface consists of thirteen buttons for operating the analyzer, a digital meter, an alphanumeric display, and a window for viewing the sample flowmeter. Teledyne Analytical Instruments Quickstart Guide Trace Oxygen Analyzer Function Keys: Six touch-sensitive membrane switches are used to change the specific function performed by the analyzer: • Analyze Perform analysis for oxygen content of a sample gas. • System Perform system-related tasks (described in detail in chapter 4, Operation.). • Span Span calibrate the analyzer. • Zero Zero calibrate the analyzer. • Alarms Set the alarm setpoints and attributes. • Range Set up the 3 user definable ranges for the instrument. Data Entry Keys: Six touch-sensitive membrane switches are used to input data to the instrument via the alphanumeric VFD display: • Left & Right Arrows Select between functions currently displayed on the VFD screen. • Up & Down Arrows Increment or decrement values of functions currently displayed. • Enter Advances VFD display to the next screen in a series or returns to the Analyze screen if none remain. • Escape Backs VFD display to the previous screen in a series or returns to the Analyze screen if none remain. Digital Meter Display: The meter display is a Light Emitting Diode (LED) device that produces large, bright, 7-segment numbers that are legible in any lighting. It produces a continuous readout from 0-10,000 ppm and then switches to a continuous percent readout from 1-25%. Alphanumeric Interface Screen The VFD screen displays values, options, and messages for immediate feedback. Set Flow: Needle valve used to adjust flow of gas sample Flowmeter: Monitors the flow of gas past the sensor. Readout is 0.2 to 2.4 SLPM of nitrogen. Standby Button: The Standby turns off the display and outputs, but circuitry is still operating. Access Door: For access to the Micro-fuel Cell,the front panel swings open when the latch in the upper right corner of the panel is pressed all the way in. Teledyne Analytical Instruments Model 3000 TA-XL-E-XL-EU Quickstart Guide Rear Panel (Equipment Interface) At the rear panel you make the gas and electrical connections to the instrument. • Power Connection: Universal AC power source. • Gas Inlet and Outlet: One inlet and one exhaust out. • RS-232 Port : Serial digital concentration signal output and control input. • Equipment Interface Connector: Interconnections for analyzer functions including: • Analog Outputs: 0–1 VDC oxygen concentration plus 0-1 VDC range ID, and isolated 4–20 mA DC oxygen concentration plus 4-20 mA DC range ID. • Alarm Connections: 2 concentration alarms and 1 system alarm. • Remote Probe: Used in the 3000TA -EU for controlling external solenoid valves only. • Remote Span/Zero: Digital inputs allow external control of analyzer calibration. • Calibration Contact : To notify external equipment that instrument is being calibrated and readings are not monitoring sample. • Range ID Contacts: Four separate, dedicated, range relay contacts. Low, Medium, High, Cal. • Network I/O: Serial digital communications for local network access. For future expansion. Not implemented at this printing. Teledyne Analytical Instruments Quickstart Guide Trace Oxygen Analyzer SETUP AND INSTALL Mount the Analyzer The Model 3000TA -EU is for indoor use in a general purpose area. It is NOT for hazardous environments of any type. It is designed for flush panel mounting. Use the four mounting holes— one in each corner of the rigid frame to panel mount the instrument. Make Gas Connections Note: Do not remove plastic caps on VCR fittings, unless you are ready to make connections. The analyzer is equipped with 1/4 inch tube fittings, and 6 mm adapters are supplied for metric system installations. 1. Connect your sample gas to the SAMPLE IN port. 2. Connect a vent line to EXHAUST OUT port. 3. Calibration gases should be tee'd into the sample inlet with appropriate valves. 4. Regulate the sample gas pressure between 2 and 50 psig sufficient to keep the front panel flowmeter reading in an acceptable range (0.5 to 2.0 SLPM). For non- pressurized sample or very low pressure, (less than 2 psig) vacuum service plumbing is recommended. 5. If greater sample flow is required for improved response time, install a bypass in the sampling system upstream of the analyzer input. 6. For optional vacuum application where the sample pressure is at atmospheric or very low p...
