To view the various AC currents, press the
I
button successively. The values are expressed in true root mean square Amps. Depending on the
client's needs (type of electrical installation), several screens are possible:
 3 phase with neutral (3ph+N)
 3 phase without neutral (3ph)
 2 phase (2ph+N)
 1 phase (1ph+N)
Note: one of the four choices above has been factory programmed as per the client's specification.

To view the generating set frequency and number of running hours, press the
F/
button. Values are expressed in Hertz (Hz) and in hours res-
pectively.
The minutes are counted from 0 to 59 minutes; on the 60th minute, the number of hours is incremen-
ted and the number of minutes goes to 0.
Example of "overview" screen showing frequency and number of generator running hours and minutes.
Note: a maximum of 32767 running hours can be displayed. The display is in whole hours.
