TIC LEXION 500 Electric System
03/05 Lex-e-21c 21c-3
Description of function:
Reel adjustment When the road travel circuit is unlocked, the relays K1, K2, K3, and K4
are supplied with voltage on pin 30 and pin 86. The corresponding
pushbutton (S37a/b/c/d) controls the relay K1, K2, K3 or K4 and thus the
respective solenoid coil (Y22/Y23/Y24/25).
The master valve (Y77) is also actuated via the diode PCB (DO) in
parallel with one of the solenoid coils (Y22/Y24/25) because this function
requires that pressure is built up in the system.
If the automatic cutterbar system is activated on machines equipped with
CEBIS, the automatic reel controller module (A16) ensures actuation of
the solenoid coils (Y22/Y23) and control of the master valve (Y77). In the
process, the setting for the reel height in the terminal (A30) is compared
to the actual value of the sensor (B39) (see also diagram 24).
Important! An automatic function for horizontal reel adjustment is
available only for VARIO cutterbars (see also diagram 21b).
Important! The cutterbar can be folded only after the reel rear end
position limit switch (Z14) has been actuated – circuit
diagram 23a.
