4.3 Display Variables and Values
See Graphic: wc_gr002944
• Generator Variables
The values shown in the top line of the ECM display are all variables
from the generator side of the machine. They are:
(1) voltage (V)
(2) phase (Ø) (or leg for single phase)
(3) amperage (A)
(4) frequency (Hz)
• Engine Variables
The values shown in the lower line of the ECM display are all variables
from the engine side of the machine. They are:
(5) engine oil pressure (psi)
(6) fuel tank quantity (shown in percentage of capacity)
(7) engine temperature (°F)
(8) battery voltage (V)
• Blinking Values
When a value on the ECM display blinks on and off, it signifies that the
variable (temperature, fuel capacity, etc.) is in a pre-alarm state. For
example, the value for the temperature reading will blink when the
temperature of the generator is below 23°C (74°F). This simply
signifies that the manifold heater (or glow plugs) will be energized to
aid in engine starting. The fuel capacity reading will blink when it is
below 25%. This tells the operator that the generator will be requiring
fuel soon. See Section Additional Variables Monitored by the ECM.
Note: If your generator has a block heater, the temperature reading
should not blink. If it does, check the block heater to make sure it is
functioning properly.
• ND (No Data), 0 (zero), or Blank Values
When a value on the ECM display reads ND, 0 (zero), or is blank, it
signifies that there is no data available for the variable.
