Output
The programmer displays the throttle max parameter as a percentage of
the active throttle voltage range. The throttle max parameter can be adjusted
from 100% to 60%, in 2% increments. The nominal throttle wiper voltage
range depends on the throttle type selected. See Table 1 (page 10) for the char-
acteristics of your selected throttle type.

Notes: Voltages shown are at the pot wiper relative to B-.
For throttle types 1 and 3, the deadband points are
defined in terms of the nominal 5kΩ pot resistance.
Using a pot of greater or lesser resistance will give
100%
different values for the deadband points.
