2017/017 Handling error message “Low int. pressure”
When the generator is started, the internal pressure of 11 bar needs to be built up. This pressure is monitored by a sensor on the dryer module. If the rate of increase is not within the tolerance as set in the firmware, the H2 production will be stopped and the error message “Low int. pressure” is shown.
There are 4 major sources for this problem:
defective Gas Liquid Separator
leak in the cell
defective dryer module
major leak in tubing & fittings
