3 Startup
3.1 "Establishing Communications " Message
NOTICE
Once the battery is connected to the generator set and any display button is
pressed, the local display shows an "establishing communications"
message for approximately 5 seconds. (This may take longer if the signal
integrity is poor between the control and display due to a bad wire or
Electro-Magnetic Interference [EMI].) Once communication is established,
the display shows the HOME screen.
The “establishing communications” message will also be displayed
whenever the control is brought out of “sleep” mode by pressing any button
on the display. Sleep mode is entered after 30 minutes without utility or
generator set power to preserve battery energy since the battery charger will
not have AC power. The 30-minute timer is reset with any button press on
the display.
3.2 "Clock Setup" Screen
NOTICE
The Clock needs to be reset whenever the battery power is lost or
disconnected, or the control has entered “sleep” mode. Sleep mode is
entered after 30 minutes without utility or generator set power to preserve
battery energy since the battery charger will not have AC power. The 30-
minute timer is reset with any button press on the display.
NOTICE
The optional Remote Monitoring System (RMS) uses the generator set's
clock. The clock must be set accurately for the RMS to function properly.
To set up the generator set clock for the current date and time:
1. From the Main screen, select Menu.
2. Use the arrow keys to highlight Clock. Select the Enter key.
3. Use the arrow keys to set the time and date.
