Mobile Generator ECM Background Information
wc_tx000713gb.fm 27
The ECM displays the AC configuration as determined by
the position of the voltage selector switch (VSS).
The ECM displays this screen to let the operator know
that the alternator protection system has been enabled.
The ECM displays the line-to-line voltage. (This screen is
shown for 3-phase VSS positions only.)
At this point, the ECM displays the run screen and the
values for the main generator variables: voltage, phase*
(leg), amperage, hertz (For generators with engines that
include ECUs, the Hz reading will be 60.0. For all others
the reading will be 61.5.) The ECM will also display the
values for the main engine variables: oil pressure, fuel
tank quantity, engine temperature, and battery voltage.
*Note: The ECM display scrolls through each phase (P1,
P2, P3) if in the 3-phase mode, or L1, L3, and L1 + L3 if
in the single-phase mode.
