DIGITAL BOARD (A32) CALIBRATION
The digital board (Figure 5-10) contains three resis-
tors that are used to calibrate the digital board for
different generator set models. One of these resis-
tors may need to be removed in order to calibrate/
initialize the PowerCommand control to the genera-
tor set model. Table 5-3 provides the necessary in-
formation to determine which resistor that may
need to be cut to select the desired generator set
model.
After the appropriate resistor selection is made, the
PowerCommand control must be re-initialized. Re-
fer to Initial Start Setup Menu in this section to initial-
ize the PowerCommand control. When the initial
setup save button is pushed, the PowerCommand
control will compare the calibration selection (cut
resistor) to the initial setup and perform one of the
following:
1. If the model numbers corresponding to the cut
resistor and the initial setup are compatible, ac-
cording to Table 5-3, the calibration is vali-
dated. The control will store the appropriate in-
formation based on calibration and initial setup
data in EEProm. The initial setup is now com-
plete and the control can start the engine.
2. If the model number corresponding to the cut
resistor and the initial setup are not compatible
the control will display the fault “INVALID SET-
UP” (fault code 401). No initial setup data is
saved and the control will not leave the initial
setup menu until this fault condition is cor-
rected.
3. If the control senses that more than one resis-
tor has been cut, the control will display the
fault “INVALID CAL” (fault code 402). No initial
setup data is saved and the control will not
leave the initial setup menu until this fault con-
dition is corrected.
