Voltages Resistances and Tolerances
Introduction
Launch Issue
Voltages Resistances and Tolerances
For AC power specifications, refer to GP 17 Electrical Power Requirements.
DC Voltage Levels and Tolerances
DC voltages should be measured between an available test point and a machine ground.
Table 1 shows the range of the common voltages.
Non-standard voltage levels will be quoted on the relevant wiring diagram or BSD. All other
voltage levels are plus or minus 10%.
Resistance Tolerances
All resistance measurement tolerances are plus or minus 10%, unless otherwise stated in the
procedure.
DC Signal Nomenclature
Figure 1 shows the signal nomenclature used in the BSDs.
Figure 1 Signal nomenclature
Table 2 shows the signal tolerances.
Non standard signal tolerances will be quoted on the relevant circuit diagram.
NOTE: The logic level shown with the signal name will be the actual signal as measured with a
service meter. This will not necessarily be the same as the logic state shown on the diagnostic
screen.
Table 1 DC voltage levels
Nominal Voltage Voltage Tolerance Range
0V 0.00 to 0.10V
+3.3V standby +3.23V to +3.43V
+3.3V +3.23V to +3.43V
+5V and +5V standby +4.75V to +5.25V
+12V +11.4V to +12.6V
+24V +23.28V to +25.73V
