5.10.2 Procedure of programming electric tachometer/speedometer AR70.3813
Indicator programming procedure:
- remove the control panel cover;
- press the button 1 (Figure 5.10.1) of the panel, this will switch the
tachometer/speedometer display to the mode of tractor unit parameter readout;
- repeatedly pressing the panel button 1 cycles through the programmed parameters “Z”,
“R”, “D”, “T” and then again “Z”;
- to enter the required value for the selected parameter, press the panel button 2 (Figure
5.10.1), this will cyclically change the fixed values of the parameters “Z”, “D”. For the parameter
“R”, the value is changed from 400 to 950 in 5 mm increments;
- using the panel button 2, select the required value of the selected parameter;
- pressing the panel button 1 again will switch to the next parameter.
- the programming mode is exited automatically if the buttons 1 or 2 are not pressed for 7.0
s. At that, the new programmed parameter values are fixed and will be used by the
tachometer/speedometer to display information.
Table below lists programmable parameter values of the tachometer/speedometer
