10.3.2.2. Oven Heaters AC Power Configuration

The two main heaters for the convection oven area of the M300EU are AC heaters. A jumper, located in line on the power connection between the relay PCA and the heaters, set the heaters in one of two configurations:

•In parallel for 115 VAC operation, or;

•In series for 230 VAC operation.

Sample gas flows within the Nafion tubes while water vapor absorbs into the tubular membrane walls and is removed. Moisture permeating the tubing is carried away by a dry purge gas within the shell that flows countercurrent to the sample gas Aout 10.3. ELECTRONIC OPERATION10.3.1.
