4.3.1 Default Menu

The default menu displays the following data:
SET - The outlet pressure required by the application.
The required outlet pressure can be adjusted up and down using the
and keys respectively.
ACT - Current actual internal / outlet pressure of the generator.
FLOW X / - Indicates the status of the generator outlet valve. "X" - Outlet is closed,
" "- Outlet is open.
100%
Each block represents 20% of the rated capacity of the generator.
During initial start up, or after a massive pressure drop, all five blocks will be shaded indicating that the generator is building up
pressure and not currently on line. When the generator is on-line and delivering gas to the application, the number of blocks shaded
will depend upon the flow required by the application.
Stand by Mode – The flow of hydrogen to the application can be interrupted by switching the
generator into standby mode.
Press and hold to select stand by. The default menu will change to the standby menu
as shown to indicate that the outlet valve is closed and hydrogen is no longer being supplied
to the application.
Note: If the generator is left in stand-by for more than 30 minutes, the hydrogen purge outlet
valve will open and slowly depressurise the generator.
To return to normal operation, press
Note: The generator will run through a start up sequence before hydrogen is supplied to the application.
Reset – Pressing the enter key (middle key) during an error condition will reset the system.
