2.15 Complex electronic control system
2.15.1 General information on complex electronic control system functions
Complex electronic control system (CECS) on tractors “BELARUS-2122.6” is designed
for carrying out the following functions:
- indication of the GB engaged gear and control of the mode for GB gear switching;
- rear and front power take-off control;
- control of front driving axle drive;
- control of rear axle differential lock;
- control of switching GB reduction unit passes, indication of GB reduction unit opera-
tion;
- warning on accident conditions of the transmission hydraulic system and HLL, trou-
bleshooting of emergency on-board circuit voltage;
- troubleshooting of failures in electronic control systems for RPTO, FPTO, FDAD, rear
axle DL, control for gear switching, GB reduction unit.
The layout of CECS controls, indicators and annunciators is shown in figure 2.15.1.
Confirmation of setting drives operation modes from buttons is accompanied by short-
time actuation of audible warning device.
When switching on marker lights, light intensity of CECS indicators and annunciators
decreases.
ATTENTION: PILOT LAMPS-ANNUNCIATORS GET SWITCHED ON AND OFF
SIMULTANEOUSLY WITH CHANGES IN THE STATE OF SYSTEM SENSORS!
