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.
