Application interface outline
Accelerator input selection
Accelerator sensors are available in three types: standard (analog voltage), backup (analog voltage) and
CAN communication (communication command) types. See
. Using accelerator sensor setting
flags allows combined use of these sensors.
In standard mapping (1), the main accelerator sensor is solely used. In generator standard mapping (O),
selecting a contact input can switch the engine speed without the use of accelerator sensors.
In option 2 mapping (2), a higher speed setting is selected from the main accelerator sensor input and the
backup sensor input. If one of the two sensors fails, the other is used to control the engine speed.
In option 3 mapping (3), the engine target speed is commanded via CAN communication.
In option 4 mapping (4), the engine target speed is commanded via CAN communication, and if CAN
communication fails, the main accelerator sensor input is used for engine speed control.
When an accelerator sensor failure is detected while the engine is running, a value immediately before the
failure is used for engine speed control. Otherwise, the engine runs at a speed (1500 min
-1
by default)
determined by the accelerator sensor failure flag.
The accelerator position sensor input (APS: E35) and the backup analog sensor input (REAN: E37) can be
flagged so that the corresponding sensor types are changed. See
. These inputs have been
flagged so that accelerator sensor signals (flag setting: 1) and foot pedal signals per SAE J1843 (flag
setting: 2 - 4) can be applied.
When these inputs are open, they must be flagged to 0 to disable sensor failure detection.
The backup analog sensor input (REAN: E37) will be able to connect to an atmospheric pressure sensor
(flag setting: 5). (Highland compensation feature pending).
