4.3.2 Conductivity
The conductivity menu gives a graphical indication of the water quality. When all 10 blocks are shaded the water quality is to
specification.
When the number of shaded blocks drops to four, the “Change Water” error message will be displayed, the water bottle indicator will
flash yellow, and an intermittent alarm will sound. Hydrogen will continue to be delivered to the application.
If the water quality degrades to the point at which none of the blocks are shaded, the outlet valve of the generator will close and a
conductivity error will be generated. The water bottle indicator will illuminate yellow and a continuous alarm will sound. Hydrogen will
not be delivered to the application.
Press
to advance to the next menu.
