acknowledged (it is to press the MODE/ACK pushbutton).
WARNING
Signal a WARNING. If flashing, the status isn’t already acknowledged (it is
to press the MODE/ACK pushbutton).
GEN-SET VOLTAGE
If ON, the MEASURES display is showing the phase-to-phase genset
voltages.
If flashing it is showing the phase to neutral voltages.
GEN-SET CURRENT
If ON, the MEASURES display is showing the genset phase currents.
MAINS-VOLTAGE
If ON, the MEASURES display is showing the phase-to-phase mains
voltages.
If flashing indicates that the inhibition input (MAINS SIMULATION) is
active.
ACTIVE POWER
If ON, the MEASURES display is showing the genset phase active
powers.
BATT./SPEED/FREQ.
If ON, the MEASURES display is showing the battery voltage (L1), the
engine speed (L2) and the genset frequency (L3).
GEN-SET VOLTAGE
GEN-SET CURRENT
BATT./SPEED/FREQ.
All flashing
The display is showing the phase-to-phase genset voltage (L1), the
genset phase current (L2) and the genset frequency (L3). Every 4
seconds is changed the displayed phase.
TEST
ON or FLASHING: if in TEST mode.
