Deadband
Output
The programmer displays the throttle deadband parameter as a percent-
age of the nominal throttle wiper voltage range and is adjustable from 0% to
30%, in 2% increments. The default deadband setting is 10%. The nominal
throttle wiper voltage range depends on the throttle type selected. See Table 1
(page 10) for the characteristics 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.
Throttle Max parameter set at 100%.
