unit management software is loaded. It displays a live readout of the kW meter, percent of load used (gauge), selected
phase, volts and amps being produced by the generator, and the fuel level with time until empty. The controller will
automatically return to this screen from any other screen after a period of inactivity.

Engine Screen
The Engine screen displays the oil pressure, coolant temperature and battery voltage on three main gauges. Below
the gauges is an hour gauge displaying the total run time on the engine. At the bottom of the screen, this screen
also displays maintenance alarm status with the time remaining (black text) or the time past (red text) a scheduled
maintenance tasks, along with the description of the maintenance procedure and the action that will take place when
the timer trips the alarm.

Note: If the measured value is outside the range of a gauge, the needle will not be displayed. The digital value below
the gauge will still show the measured value.
• Oil Press: Displays engine oil pressure. Current coolant temperature is displayed directly below the gauge
at all times. The gauge registers oil pressure between 0-100 psi (0-689 kPa). Normal operating pressure is
between 35-80 psi (241-552 kPa).
• Coolant Temp: Displays engine coolant temperature. Current coolant temperature is displayed directly
below the gauge at all times. The gauge displays coolant temperature between 150°-250°F (66°-121°C).
Normal operating temperature of the unit is between 180°-200°F (82°-93°C) with an average ambient air
temperature of 70°F (21°C).
