Cleaning
Do not use any cleaning solution to clean the Gateway
enclosure or cover. Clean with a damp cloth or sponge.
The Gateway contains electronic circuitry. Use extra cau-
tion not to drip water inside the Gateway. If water or other
liquid enters the Gateway, disconnect power until com-
pletely dry.
Connection Details
Light Emitting Diodes (LEDs)
There are two LEDs at the front on the enclosure:
•Red LED: Represents system power.
– If red LED is on, Gateway is powered.
– If red LED is off, Gateway is not powered.
•Green LED: Represents RS-485 (only) communi-
cation status.
– If green LED is blinking, RS-485 communication
is working properly. The blinking rate will be 0.25
seconds on and 0.25 seconds off (2 Hz).
– If green LED is off, RS-485 communication is not
working properly or RS-485 interface is not con-
nected.
Connecting to the Gateway
The Gateway can be accessed via Ethernet.
Ethernet Connection
1. To connect via Ethernet, the Ethernet IP Address is
required. This information can be accessed via the
Power Zone 410’s Display. See Technical Manual
Power Zone Controller for further details.
NOTE: The IP address and subnet mask on your PC's
Ethernet port must be set to a fixed IP address in the
same subnet range as the IP address of the Gateway.
2. Connect Ethernet cable from the Gateway to the
PC.
3. Open a web browser (Google Chrome™ preferred)
and enter the Ethernet IP address in the top bar of
the browser. After a few minutes, the web browser
should display the Generac app.

Home Screen Bargraphs
See Figure 3-6. The center of the screen contains data in
the form of bargraphs. The color of the bar changes to
yellow once the measurement triggers a warning (either
high or low). The color of the bar changes to red once the
measurement triggers an alarm. If a measured value
exceeds the bargraph range, the bargraph is outlined in
red.
Figure 3-6. Bargraph
Alarm Ribbon
See Figure 3-7. This area is hidden when there are no
alarms or warnings. If an alarm or warning condition
occurs, a “Ribbon” will be drawn across the lower portion
of the screen showing the condition. Select the icon that
appears to initiate a different action for each icon, as
shown below.
NOTE: The “Check Engine” icon is displayed only for
emissions related Diagnostic Trouble Codes (DTCs).
Normally, these DTCs cannot be cleared manually. They
will clear when the system has met the required condi-
tions for the required length of time or number of run
cycles.

Date/Time
See Figure 3-11. The system date and time can be set
from the (E) Setup icon (on the bottom banner). Navigate
to Setup → Calendar → Date/Time.
Changing the date/time on the Gateway means a change
to the “System Time” and this will eventually change all
other connected equipment (displays and modules) in the
system. This will affect timestamps of data and execution
of calendar based commands.
The default time setting shown on the Gateway is set via
the date format setting on the controller built-in display.

Alarms and Warnings
The Alarms and Warnings screen displays only active
and present alarms and warnings.
A Warning (A) is considered active when the condition for
the warning is present. A Warning is low severity and
does not need to be acknowledged.
An Alarm (B) is considered active when an alarm condi-
tion is or was present, but the alarm has not yet been
acknowledged. An Alarm is high severity and must be
acknowledged. The generator will not operate when an
Alarm is present.
The list of active alarms and warnings is organized into
sections with controller alarms and warnings appearing
at the top of the list followed by alarms and warnings for
each transfer switch on the RS485 bus connected to the
Gateway AUX 485 port. Each section is preceded by a
row of orange text that describes the device that gener-
ated the alarm and a “Reset” button that can be used to
reset the alarms on that device. If the conditions for an
alarm or warning are still present, they will reappear as
new.
NOTE: Resetting controller alarms can result in the
generator starting if all other start conditions are active.
Alarms and Warnings are displayed with their respective
icons to the left followed by the word “Alarm” or “Warning”
followed by text describing the alarm.
The System Detail menu provides access to the Alarm
logs, 410 controller Run logs and Maintenance logs, TX
alarm and event logs, contact information, and system
notes and maintenance notes.

Alarm, Warning, Run, and Maintenance Logs
See Figure 3-23. The Alarm, Run, and Maintenance Log
screens show a chronological list of alarm, run and main-
tenance logs. See PZ 410 Controller Technical Manual
for list of possible alarms and warnings. Each alarm entry
is date and time stamped and shows the alarm text and
e-code of the parameter at the time it occurred. The list
filters to show alarms, warnings, run stop/starts, and
maintenance items. The list is paginated and up to 1,000
entries for each log type can be stored.
The log exports to USB devices connected to the USB
port of the Gateway or to the default download location of
