Description of function:
Cutting table adjustment
When the road travel circuit is unlocked, the switches of the external
operation for the VARIO cutting table (U15/U16) and the VARIO module
(A27) are supplied with power.
By operating the switches (U15/U16) the power is passed directly to the
corresponding solenoid coils (Y79/Y80).
When the VARIO cutting table is operated using the multifunction handle,
the solenoid coils (Y79/Y80) are actuated via the relays K9/K10.
During operation in automatic mode (VARIO automatic mode ON), the
VARIO module (A27) controls the solenoid coils (Y79/Y80) according to
the values programmed in the terminal (A30).
The master valve (Y77) is actuated via the diode PCB (DO) in parallel
with one of the solenoid coils (Y79/Y80) because these functions require
that pressure is built up in the system.
On the V-belt spring tensioner, the limit switch (Z65) avoids that the rape
position is selected when the grain V-belt is installed.
Important! Any cutting table adjustment requires the switch of the
cutting table lock (U17) to be in ON position.
Folding the cutterbar The cutterbar can only be folded when the limit switches (Z14) are closed.
To do so, the reel must be pulled back all the way and the lock must be
released.
The master valve (Y77) is actuated via the diode PCB (DO) in parallel
with one of the solenoid coils (Y65/Y66) because these functions require
that pressure is built up in the system.
