Calibrating Mode For The Hidden Functions; Parameters - Valtra 6000 Workshop Manual

34. Autocontrol ---III
Note! Display shows first time and Valmet
name after the current is switched on. When
starting driving the display shows first the
driving speed (if other keys are not pressed).

1. Switch for differential lock: --- rear edge down=manual
--- front edge down=automatic
2. Switch for quick ---shift gear: --- rear edge down=manual
(PS Algorithm)
--- front edge down (A1)=automatic change according to the max. torque
3. Switch for 4WD:
--- front edge down=automatic
The function keys have been presented in the figures on the
next page. Hidden functions of the keys have been marked
with the double boxes. These hidden functions can be acti-
vated with a special function code
The function keys act as number keys when the SET ---key is
pressed.

Calibrating mode for the hidden functions

(this mode is needed when calibrating the quick ---shift gear or
when checking the speed sensors)
Some functions have been hidden from the Operator by a
special code. The calibrating mode is activated as follows:
--- switch on the current and start the engine
--- press the function keys in the following order;
9 ---1 ---0 ---4 ---0 ---9 (do not use the SET ---key, display changes
every time the key is pressed).
Note! Now the quick ---shift gear is ready for calibrating and
the speed sensors can be checked. If the current is switched
off the code must be input again.
--- escaping from this mode is done by switching off the cur-
rent.
AUTO
--- middle position (A2)=automatic change according to the max. effect
--- rear edge down=manual

Parameters

In the factory a parameter file is input with a micro computer
into every AC---III system . The parameter file includes: trans-
mission type, engine type, engaging limits for the diff. lock
and the 4WD and the display language. These functions are
different on different tractors.
PC is connected to the AC---III socket X10C with a middle wire.
In PC there must be a Service Program which sends the para-
meter file into the ECS. See Code 343.
If a fault occurs in the actual parameter file , the ECS replaces
the damaged file automatically with a default parameter file.
The display shows this with text DEFAULT PARA every time
the current is switched on.
The tractor functions properly with the default parameter file,
but as soon as possible the actual parameter file must be input
with a PC into the system.
Micro computer can also be used for detailed fault tracing for
the AC---III system (see Code 342)
