EQ - Triggers the battery charger to complete the equalization process. If an AC source is
connected and the ‘MAXIMUM AC AMPS IN’ switch is in the AC1 position, the equalization process will
begin. If the ‘MAXIMUM AC AMPS IN’ switch is in the AC2 position, the generator will start the
equalization process the next time the generator is automatically started. Once the equalization process
has been completed, the cursor will return to the AUTO position. If you are battery charging - in FLOAT
charge - from the Utility or a manually controlled generator, you may initiate another BULK charge by
moving the cursor through EQ.
Gen failed to
start NO
If YES is displayed, it indicates that the automatic generator start system was not able to successfully
start the generator. The system completes five start cycles and requires that the generator operate for a
minimum of 5 minutes before the starting attempts counter is cleared. To manually clear this error, access
the SET GENERATOR menu item by pressing the green GEN MENU button on the SWRC, then select
OFF and then AUTO or ON using the set points buttons.
Gen stopped due
to V/F NO
If YES is displayed, it indicates that the automatic generator start system was not able to successfully
connect to the generator after it was running. If the generator runs for 10 minutes without operating in the
AC Voltage and Frequency tolerance windows, then the automatic start system stops the generator and
indicates an error condition. To manually clear this error, access the SET GENERATOR menu item by
pressing the green GEN MENU button on the SWRC, then select OFF and then AUTO or ON using the
set points buttons. The acceptable frequency range is 53 to 67 Hertz for 60-Hertz models. The acceptable
AC input voltage window is determined by the INPUT UPPER LIMIT VAC and INPUT LOWER LIMIT
VAC settings. See AC INPUT REQUIREMENTS on page 63 for more information.
Gen max run time
error NO
If YES is displayed, it indicates that the generator ran for a period of time that exceeded the SET MAX RUN
TIME menu item setting under the GEN AUTO START SETUP (12) menu heading. This error indication will
only light to let the user know that the generator ran longer than originally expected. This error LED is an
advisory indication only and will not allow the inverter to stop the generator. To disable the MAX RUN TIME,
set the time to zero. To manually clear this error, access the SET GENERATOR menu item by pressing
the green GEN MENU button on the SWRC, then select OFF and then AUTO or ON using the set points
buttons.
Gen speed error
NO
If YES is displayed, it indicates that the automatic generator start system has detected that the generator
frequency is with in acceptable tolerance, but is not well adjusted. This error condition is an advisory error
only. It will cause the red ERROR LED to blink, but will not cause the automatic generator start system to
shut down the generator.
The ERROR LED can be used to adjust the generator frequency. When the frequency is within 3 hertz of
the nominal value (57 to 63 for 60 Hz units, 47 to 53 for 50 Hz units), the LED will be off. Once outside
this window, the LED will blink slowly. A frequency meter is also provided in the METERS (4) menu
heading to allow a more precise adjustment of the generator. It is able to indicate the frequency of the
generator only after the inverter has been able to synchronize to the generator. The inverter/charger has
synchronized with the generator when the CHARGE (orange) LED - BULK or FLOAT LED on the SWRC
- has turned on. The acceptable frequency range is 53 to 67 Hertz for 60-Hertz models.
