Teledyne 3190 Electrical Connections, Installing the Micro-Fuel Cell / Cell Block Orientation

Trace Oxygen Analyzer Installation 3

For special applications the Micro-Fuel Cell may also be of a different type than the standard A-2C, B-2C or Z-2C unit. If this is the case, the pertinent cell specifications will be given in the addendum.

3.2.3Installing the Micro-Fuel Cell / Cell Block Orientation

A Micro-Fuel Cell is included as a separate item. It must be installed prior to instrument use.

Also, once it is expended, or if the instrument has been idle for a lengthy period, the Micro-Fuel Cell will need to be replaced.

Important Installation Note!

During the Installation and/or Replacement of the MFC, Membrane surface MUST ALLWAYS FACE DOWNWARD, and the Contact side of the Membrane, MUST be placed FIRST into Analysis Unit.

The reason for proper Installation/Replacement is, if any bubble that develops as the electrolyte dries out will be directed by the gravity away from the membrane.

To install or replace the Micro-Fuel Cell, follow the procedures in

Chapter 5, Maintenance.

3.3Electrical Connections

Figure 3-1 shows the two alternate Model 3190 rear panels. The first illustration shows the AC powered version, and the second illustration shows the DC powered version. The difference between them is the power connec- tions. Both versions have identical connections for the External Probe, the alarms, and for the digital and analog concentration outputs. For detailed pinouts, see the wiring/interconnection drawings in the Drawings section at the rear of this manual.
