TIC LEXION Montana 570-520 Electric System
03/05 Lex-e-20s 20s-3
Description of function:
1/2
Raise / lower front
attachment
When the road travel circuit is unlocked, relays K5 and K6 are supplied
with power by relay K49. The pushbuttons (S38a and S38b) have different
pressure stages. When actuating the pushbutton slightly to the first stage,
earth is connected as a signal to the AUTOCONTOUR module (A8). The
module (A8) actuates the respective solenoid coils (Y85 or Y86) in a
modulated way – Slowly raise/lower function.
When pressing the pushbuttons (S38a or S38b) to the second stage, the
corresponding relays K5 and K6 are actuated and consequently also the
respective solenoid coils (Y85 or Y86) – Quickly raise/lower function.
The master valve (Y77) is actuated via the diode PCB (DO) in parallel
with the front attachment raise solenoid coil (Y85) because this function
requires that pressure is built up in the system.
During automatic cutterbar guiding, the AUTOCONTOUR module (A8)
actuates the corresponding solenoid coils until the set values and actual
values of the corresponding sensors match – Circuit diagram 24a.
Cross levelling When the road travel circuit is unlocked, relays K7 and K8 are supplied
with power by relay K49. By actuating the function pre-selection switch
(S69) to the cross levelling position, the respective relay K5 or K6 and
consequently the corresponding solenoid coil (Y67/Y68) is actuated as a
function of switch (S46).
The AUTOCONTOUR module (A8) also receives the signal from the
manual lateral control in parallel with the lateral control solenoid coils
(Y67/Y68). The master valve (Y77) is now actuated via the diode PCB
(DO) by the AUTOCONTOUR module (A8) because this function requires
that pressure is built up in the system.
During automatic cutterbar guiding, the AUTOCONTOUR module (A8)
actuates the corresponding solenoid coils until the set values and actual
values of the corresponding sensors match.
Note: The switch provided at the bottom side of the multi-function handle
controls both the VARIO cutting table adjustment (S45) and
the manual cutterbar cross levelling (S46), depending on
the function pre-selection switch (S69).
MONTANA cross levelling Note: On MONTANA machines, the swing angle and the cutting
angle can be varied by adjusting the front attachment frame,
in addition to the CAC function – see circuit diagram 41s
and 41t.
