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 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.

Install the Micro-fuel Cell

The Model 3000TA-XL-EU can be equipped with either the standard B-2CXL Micro-fuel

Cell or as an option, Teledyne’s Insta Trace cell.

B-2CXL Micro-fuel Cell

To install this cell:

1. Remove power to the instrument.

2. Open the front panel door.

3. With one hand placed underneath the cell

block ready to catch the Micro-Fuel cell, lift

up on the stainless steel gate in front of the

cell block. This releases the cell and cell

holder from the block. The cell and holder will

fall out in your hand.

CAUTION: THE CELL IS SHIPPED SEPARATELY

INSIDE TWO BAGS FILLED WITH

OXYGEN-FREE INERT GAS. USE

CARE TO AVOID EXPOSING THE

CELLTO AIR FOR ANY LONGER THEN

NECESSARY TO INSTALL THE ITEM.

Insta-Trace Micro-fuel Cell

Note: The Insta Trace Micro-fuel Cell has a short recovery time after ambient air

exposure, however minimizing this exposure still reduces the recovery time

necessary.

CAUTION: DO NOT TOUCH THE SENSING SURFACE OF THE CELL. IT IS COVERED

WITH A DELICATE TEFLON MEMBRANE THAT CAN LEAK WHEN

PUNCTURED.

Model 3000 TA-XL-EU Quickstart Guide

Teledyne Analytical Instruments 7

1. Place the cell on the holder with the screen side facing down.

Note: There is a small location hole drilled in the holder. This hole mates with a guide

pin on the bottom rear of the cell block. The hole in the cell block holder must

align with the guide pin on the cell block.

2. Remove power from the instrument.

3. Remove the old sensor (if installed). Discard in accordance with all Federal, State,

Local or other regulations which may apply.

4. Purge the analyzer at approximately 1 SCFH flow rate with nitrogen (or applicable

sample gas with the sensor holder removed).

5. Remove the new sensor from its double bag

storage.

6. Remove the sensor shorting button.

7. Place the sensor inside the cell block.

8. Hold the sensor up into the block while

positioning the cap under the sensor.

Vigorously push the cell holder with the

sensor into the cell block, thus puncturing

the protective film/seal cover.

9. 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.

10. Purge the system using sample or zero gas.

11. Power the system back up.

The Insta Trace sensor will typically reach a stable low value within 30 minutes or less after

installation.
