4.7. Faults
Six "major" faults can be displayed on the GNM 100
The faults are displayed in code on the two display lines and the red signal light lights up.
The only way to reset the faults is to turn off the module for a minimum of 30 seconds and to put it on
again by means of the push button (7).
