2.16.4 Flow restriction

The electronic system controlling the hydraulic distributor EHS sections performs a
function of "flow restriction" to drive coupled agricultural implements operating with less oil
flow. The set-up function of "flow restriction" provides for more precise and smooth control
at the given rates. At the standard mode oil flow value can be changed from 0 to 80 l/min
per each section, with the function of "flow restriction" turned on the oil flow value can
changed from 0 to 60 l/min.
To activate this function the IEP 34 (figure 2.2.1) has got four buttons 2 (figure
2.16.7), turning on "flow restriction" for each hydraulic distributor section.
Working order with the function of "flow restriction" is the following:
- pressing buttons 2, turning on "flow restriction", select required sections of the hy-
draulic distributor EHS, for which it is needed to restrict the flow. After the buttons 2 have
been pressed, the annunciators 1 of the corresponding sections of the hydraulic distributor
EHS light up;
- control the selected sections by means of the joysticks taking into account the cur-
rent "flow restriction";
- the function of "flow restriction" is turned off by repeated pressing the button 2 of
the corresponding sections, after that all annunciators 1 go out.
1 – annunciators of "flow restriction" activation for the hydraulic distributor section; 2
– buttons to activate "flow restriction" for the hydraulic distributor section.

the hydraulic distributor EHS sections.
