Troubleshooting

8.1.

Alarms

The generator informs about a malfunction or the necessity of intervention in
two different ways: warning or error .

WARNING

It indicates a condition that may require the intervention of the operator, but gas
production is not shut down. 
In WARNING status:

• an acoustic signal is emitted;
• the following page is displayed

ERROR

It indicates a condition that prevents continuation of gas generation. The gen-
erator shuts down production and depressurizes the generation module.
In ERROR status:

• an acoustic signal is emitted;
• the LED on the front panel is intermittent red;
• the following page is displayed
