TIC LEXION 500 Electric System
03/05 Lex-e-21b 21b-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.
When activating the automatic cutterbar function on machines equipped
with CEBIS, the automatic reel controller module (A16) ensures actuation
of the reel height whereas the VARIO module (A27) is responsible for
adjusting the cutting table and the reel horizontally. In this process, the
settings in the terminal (A30) are compared to the actual values of the
sensors (B39/B40/B70) and/or of the potentiometers (R11/R12/R30).
The limit switch (Z64) ensures that the reel will never collide vertically with
the cutting table and/or will not lower onto the knife. On the V-belt spring
tensioner, the limit switch (Z64) avoids that the rape position is selected
when the V-belt is installed.
