General
The HEINZMANN Digital Governors of the PANDAROS series have been designed as speed
governors for diesel and gas engines with low and medium power. In addition to their primary
purpose of controlling speed, these governors are capable of performing some other tasks and
functions.
The control system consists of the control unit, the actuator, the setpoint adjusters, the sen-
sors, and the connection cables.
The control unit includes the control electronics. At the core of the control unit is a very fast
and powerful 16 bit microprocessor. The actual controller program on which the processor
operates, is permanently stored in a FLASH-EPROM.
The current engine speed is sensed by a magnetic pick-up on the flywheel or a measuring wheel.
One temperature sensor can measure the engine temperature and can cause changings of gov-
ernor parameters or alarm messages.
The speed setpoint, additional sensor inputs and the inputs for the analogue accessory are de-
pending on variations.
In the case of the DC 6-00 variant, which offers the largest functional scope and flexibility,
the user must configure all inputs and outputs themselves.
With regard to the other variants, no additional outputs are provided aside from the error mes-
sage output. In certain cases, the inputs are already specifically pre-configured and all pa-
rameters that are not required for the respective application are omitted so as to maintain a
clearer overview of the controller and to make start-up easier to perform.
With the serial interface ISO 9141 resp. RS 232 is communication to other devices possible.
