Percent Oxygen Analyzer Installation
Teledyne Analytical Instruments 17
For special applications, the type of External Probe unit supplied
may vary depending on the specific process. With these systems,
specific installation and interconnect information is given in a separate
probe manual or in an addendum to this manual depending on the model
External Probe used. The addendum will reference the specific Outline
and Interconnection Drawings in the Drawings section of this manual,
and provides any other appropriate information.
For special applications the oxygen sensor may also be of a
different type than the standard E-2 sensor. If this is the case, the
pertinent cell specifications will be given in the addendum.
3.2.3 Installing the Oxygen Sensor
The oxygen sensor is included as a separate item. It must be
installed prior to instrument use. The standard instrument is shipped
with an E-2 oxygen sensor. Some units on special request are fitted with
the optional C-5 or C-5F oxygen sensor. The installation procedure is
different for these cells. See Section 5.2.4.
Once the cell is expended, or if the instrument has been idle for a
lengthy period, the oxygen sensor will need to be replaced.
To install or replace the oxygen sensor, follow the procedures in
Chapter 5, Maintenance.
3.3 Electrical Connections
Figure 3-1 shows the two alternate Model 3290 rear panels. The
difference between them is the power connections. The first illustration
shows the AC powered version, and the second illustration shows the
DC powered version. Both versions have identical connections for the
External Probe, the alarms, and for both digital and analog concentration
outputs. For detailed pinouts, see the wiring/interconnection drawings in
the Drawings section at the rear of this manual.
Primary Input Power (AC version): The power cord receptacle,
fuse block and Power switch are located in the same assembly. A 6-foot
(1.83 meter), standard AC power cord is supplied with the Control Unit.
Insert the female plug end of the power cord into the power cord
receptacle.
The universal power supply allows direct connection to any 100-
240 VAC, 50/60 Hz power source. The fuse block, to the right of the
