DISPLAY APPLICATION RATE PERCENT
Normally when driving the application rate can be seen to move up and down, this
is quite normal. To even out these variances a value can be encoded that
represents how much, in percent of the required application rate, the rate
displayed can vary from the required (encoded) rate.
Example:
• The encode rate = 20 t/ha.
• The rate displayed varies from 19 to 21 t/ha.
• The “Display doserate Percent” is encoded to 5%.
• The displayed rate thereafter remains stable at 20 t/ha.
DEADBAND
Under normal working conditions the Teejet500 program will always try and
regulate the distributed slurry in accordance to the current speed, working width
and the requested application rate. The regulation constantly monitors the flow
and will control the outputs accordingly.
This means that the regulation will try and compensate for even the smallest
difference between the wanted and the actual application rate.
Sometimes this is not optimal since this puts unnecessary strain on the hydraulics
that handles the regulation, compared to the effect it has on the actual output.
Entering a Deadband percent value will make the regulation stop when the
measured application rate is within this percent value of the requested application
rate.
Example:
• The encode rate = 20 t/ha.
• The “Deadband” is encoded to 5%.
• The regulation (outputs) stops when the measured application rate is within
19 to 20 t/ha.
PC COMMUNICATION
The Teejet 500 controller is equipped with a serial connection capable of
communicating with a PC. This is used by the Super-User customers to transfer
files between the Teejet 500 Slurry controller and the PC.
File transfers can be used for:
• Transferring new languages.
• Transferring counter data CNTDATA.HTM and CNTDATA.CSV files.
The transfer of data is done with dedicated PC tools. In order to enable the Teejet
500 Slurry controller for PC communication, the controller must be left in this menu
(see below). The PC tools will not be able to communicate with the controller if this
menu is inactive.
