Resumen del manual


• For vacuum service (5-10 in Hg), install the restrictor without the blue dot to the EXHAUST port. 2. Connect your sample gas to the SAMPLE IN port. 3. Connect a vent line to EXHAUST OUT port. Teledyne Analytical Instruments Model 3000TA Quickstart Guide 4. If using remote calibration feature: • Connect zero gas to the ZERO IN port. • Connect span gas to the SPAN IN port. 5. Otherwise, calibration gases must be Tee'd into the sample inlet with appropriate valves. 6. Regulate the sample gas pressure between 2 and 50 psig sufficient to keep the front panel flowmeter reading in an acceptable range (0.1 to 2.4 SLPM). For non- pressurized sample or very low pressure, (less than 2 psig) vacuum service plumbing is recommended. 7. If greater sample flow is required for improved response time, install a bypass in the sampling system upstream of the analyzer input. 8. For optional vacuum application where the sample pressure is at atmospheric or very low pressure, the instrument should be fitted with the vacuum service option. This option locates the flow control valve on the exhaust side of the Micro-fuel Cell. Note: Exhaust connections must be consistent with the hazard level of the constituent gases. Check Local, State, and Federal laws, and ensure that the exhaust stream vents to an appropriately controlled area, if required. Electrical Connections CAUTION: READ ALL SAFETY INFORMATION REGARDING ELECTRICAL HAZARDS ASSOCIATIED WITH THIS INSTRUMENT BEFORE MAKING ELECTRICAL CONNECTIONS. CAUTION: POWER IS APPLIED TO THE INSTRUMENT'S CIRCUITRY AS LONG AS THE INSTRUMENT IS CONNECTED TO THE POWER SOURCE. THE RED SWITCH ON THE FRONT PANEL IS FOR SWITCHING POWER ON OR OFF TO THE DISPLAYS AND OUTPUTS ONLY. Teledyne Analytical Instruments Quickstart Guide Trace Oxygen Analyzer • Connect primary input power: Insert the power cord into the power cord receptacle. • Install the fuse: Fuses are not installed at the factory. Be sure to install the proper fuse as part of installation. Place small screwdriver in notch, and pry cover off, as shown. To change between American and European fuses, remove the single retaining screw, flip fuse block over 180 degrees, and replace screw. Replace fuse as shown below and reassemble housing. • Connect Analog Outputs There are four DC output signal connectors with spring terminals on the rear panel where the analog output signals are available. There are two wires per output with the polarity noted. See Section 3.3.2 in the Instruction Manual for detailed descriptions of the analog outputs. • Connect Alarm Relays: Use the three alarm-circuit connector spring terminals on the rear panel for making connections to internal alarm relay contacts. • Connect Digital Remote Cal Inputs: These input terminals accept 0 V (off) or 24 V dc (on) inputs for remote calibration control. • Connect Cal Contact: This relay contact is closed while analyzer is spanning and/or zeroing. Teledyne Analytical Instruments Model 3000TA Quickstart Guide • Connect Range ID Contacts: There are four dedicated Range ID relay contacts on the rear panel. The first three ranges are assigned to relays in ascending order. Range 1 ID— Low range Range 2 ID— Medium range Range 3 ID— High range Range 4 ID—Air Cal Range (25%). • Network I/O: A serial digital input/output for local network protocol. At this printing, this port is not yet functional. It is to be used in future options to the instrument. • Connect the 9-pin D connector to the RS-232 serial port. See Section 3.3.2 in the Instruction Manual for information on setting up serial communication for this instrument. Install the Micro-fuel Cell The Model 3000TA is designed to accept the L2C Micro-fuel Cell or as an option, it can use the B2 series of Micro-fuel Cells by incorporating a spacer adaptor (Teledyne P/N B66378). L2C Micro-fuel Cell 1. Remove power from the instrument. 2. Remove the old sensor (if installed). Discard in accordance with all Federal, State, Local or other regulations which may apply. 3. Purge the analyzer at approximately 1 SCFH flow rate with nitrogen (or applicable sample gas with the sensor holder removed). 4. Remove the new sensor from its double bag storage. 5. Remove the sensor shorting button. 6. Place the sensor inside the cell block. 7. Place the sensor on the sensor holder so that the gold contact plate of the sensor is facing upwards. 8. Install the sensor and sensor holder into the cell block. Teledyne Analytical Instruments Quickstart Guide Trace Oxygen Analyzer 9. With the O-ring in place, align the guide pin with the hole on the cell holder. Then, with the holder, lift cell into the cell block. 10. Push the gate on the cell block down so that the slots on the side of the gate engage the locating screws on the side of the block. This forces the holder into position and forms a gas-tight seal. 11. Purge the system using sample or zero gas. 12. Power the system back up. If the installation is carried out quickly enough, the sensor will reach a ...
