Generator Monitoring - Generac Power Systems MOBILEPOWER MMG130D Operating Manual

• "FAULT RESET" Button: Press this button to clear the fault from the LCD window after the fault has been
corrected. Press "FAULT RESET" and "ENTER" to clear the John Deere ECU Alarm List Codes.
3. The Liquid Crystal Display (LCD)
• This window will toggle between the generator display screen and the engine display screen upon startup
of the unit. By viewing these screens, the operator will be able to monitor both the engine and generator
status while the unit is running.
4. The "DIAGNOSTICS" Keypad
• "" Scroll-Up Button: Press this button to scroll-up within the LCD window.
• "" Scroll-Down Button: Press this button to scroll-down within the LCD window.
• "PAGE SELECT" Button: Pressing this button will select the next display screen.
• "ENTER" Button: Pressing this button will place you inside the particular display to review the generator's
pre-programmed setpoints or parameters.
5. The "STATUS" Light Emitting Diodes (LED's)
• These six LED's will illuminate to display the current operational status of the generator;
○ "ALARM/FAULT": Indicates active or inactive alarms, but not reset shutdown alarms.
○ "WARNING": Indicates an active or inactive alarm, or a warning alarm that has not been reset.
○ "READY/MANUAL": Indicates the controller is ready to start and in the Manual mode.
○ "READY/AUTO": Indicates the unit is in the "AUTO" mode and ready for the remote start signal.
○ "RUNNING": Indicates the unit is running.
○ "SUPPLYING LOAD": Indicates a load is being applied to the generator.

GENERATOR MONITORING

Generator information is shown on the Liquid Crystal Display (LCD) window in a toggling manner with the engine
information after the first 60 seconds of operation, then every five seconds. The generator display screen will show
frequency, nominal voltage, nominal amperage, line to neutral voltage, line to line voltage and amperage.
Note: When loading the generator, it is important to observe the amperage to determine the load balance on each
line of the generator. Minor load unbalances, usually 10% or less, will not cause any particular problems. Every effort
should be made to distribute the load equally between all lines.
• Hertz: Displays output frequency.
• NomVolt: Displays nominal voltage
• NomAmps: Displays nominal amperage
• Generator Output Voltage: Displays line to neutral, single phase (1Ø).
• Generator Output Voltage: Displays line to line, 3 phase (3Ø).
• Amps: Displays the AC output amperage produced by the generator.
