APPENDIX A: FEATURES & FUNCTIONS
Temperature extreme data storage
The maximum and minimum temperatures read at the heatsink at any time
during powering of the controller are stored in the controller's memory. These
values (which can be accessed via the programmer's Test Menu) are cleared each
time the controller's diagnostic history file is cleared. Each time the controller's
power is cycled, the initially recorded maximum and minimum temperatures will
be accurate only to within 10°C.
Throttle map
The throttle map (duty factor as a function of throttle position) is adjustable, so
that you can provide the proper feel for the many types of vehicles that use the
1214-/15-/19-8 controller. The throttle map parameter is called "ramp shape";
see the entry under Ramp shape for more information.
Throttle response
The dynamic throttle response (duty factor as a function of time) is shaped by the
acceleration rate setting. Dynamic throttle response is linear. The newest throttle
input is mapped to the throttle map, and the controller then automatically
accelerates (or decelerates) through a straight line until the new throttle demand
is obtained.
Throttle types
The 1214-/15-/19-8 controller accepts a variety of throttle inputs, through
various combinations of its four throttle input pins. The most commonly used
throttles (5kΩ–0 and 0–5kΩ pots, 3-wire pots, 0–5V, 0–10V, and the Curtis
ET-XXX electronic throttle) can be hooked up simply by selecting the appropri-
ate throttle type in the handheld programmer's Program Menu. Additional
throttle types can also be accommodated; please contact the Curtis office nearest
you.
Throttle full range produces 0–100% duty factor at the controller output
(unless limited by other conditions). Throttle fault detect is performed on the
throttle input signals and virtually eliminates the possibility of runaway opera-
tion. Adjustments and settings are independent of throttle type. However,
throttle fault conditions will vary by throttle type.
