) Correction of PID parameters
To optimize the dynamics for every operating point, the PID parameters may be cor-
rected in dependence of speed, temperature and load by means of freely programmable
stability maps.
i) Speed dependent fuel limitation
It is possible to program fuel limitation curves in dependence of speed so that for all
speeds there can be torque reduction as is admissible for the engine or desired by the us-
er.
j) Temperature dependent idling speed and fuel limitation
At low temperatures, the engine can be run at some higher idling speed. With the engine
warming up, idling speed is reduced to its normal value. It is possible to program fuel
limitation curves in dependence of temperature so that for every temperature there will
be torque reduction available as is admissible for the engine or desired by the user.
k) Operating hour meter
The operating hours when the engine is turning (speed is detected) will be added.
l) Failure diagnosis and display
If a sensor or the actuator is at fault, an alarm is issued and there will be a change-over
to emergency operation if so provided or an engine shutdown. Internal errors get detect-
ed also and they will be stored as all other failures. All failures can be read out with an
external hand programmer or with a communication program on a PC or laptop with
communication cable.
m) Communication
An ISO 9141 interface is provided to enable communication with a Heinzmann com-
munication tool.
