GENERATOR MONITORING
Generator information is shown on the LCD display in a repeating manner while the unit is running in
MANUAL or AUTO mode. Generator information will show the voltage, amperage and frequency of each
phase.
Additional information can be viewed when the unit is MANUAL or AUTO modes. Pressing "PAGE SE-
LECT" then "UP" or "DOWN" on the key pad will display, Alarm Screen, Hour Screen, and Power Detail
Screen displays.
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 5% or less, will not cause any particular
problems. Every effort should be made to distribute the load equally between all lines.
1. PHASE - Indicates generator configuration, 3 phase or single phase.
2. HERTZ - Displays output frequency.
3. NOMINAL VOLTS - Displays generator nominal voltage in current phase switch selection.
4. NOMINAL AMPS - Displays maximum amps in current phase switch selection.
5. GENERATOR OUTPUT VOLTAGE - Line to Line display.
6. AMPS - Displays the AC output amperage produced by the generator.
7. GENERATOR OUTPUT VOLTAGE - Line to Neutral display.

ENGINE MONITORING
Engine information is shown on the LCD display in a repeating manner while the unit is in MANUAL or
AUTO mode. Engine information will show the oil pressure, water temperature, fuel level and battery
voltage.
8. OIL - Displays engine oil pressure. The display registers oil pressure between 0-100 psi. Normal
operating pressure is between 35-80 psi.
9. TEMPERATURE - Displays the temperature of the engine's coolant. If the coolant temperature
exceeds the Max Water Temp the engine will automatically shut down. Zero "0" will be displayed until a
minimum of 100° F is reached.
10. FUEL - Displays the relative fuel level in the fuel tank in percent (50% = 1/2 tank, 75% - 3/4 tank, etc.).
If the fuel level drops below a programmed Fuel Shutdown Percent the engine will automatically shut
down.
11. BATTERY - Displays the engine battery voltage. A normal reading is 13-14V on 12 volt systems and
24-26V on 24 volt systems.
