Disconnecting the automatic dump function
(ADO)
In certain cases the automatic dump function
must be disconnected. The most common case is
before operating a separate stabiliser control
valve (which is not equipped with spool sensors)
To disconnect the automatic dump function:
1. Press the Button
①
.
The LED
②
is lit constantly when automat-
ic dump function is disconnected.
2. Press the Button
①
again.
The automatic dump function is now con-
nected again.
When the power is switched on, the automatic
dump function is always connected.
ASC Automatic Speed Control
The ASC function automatically provides the
extra power by reducing the speed smoothly,
when working close to the rated capacity. When
the load decreases, normal speed is restored.
ADC Automatic Duty Control
The purpose of the ADC function is to increase
the lifting capacity by 10%.
The first boom pressure sensors indicate if there
is a positive or negative pressure on the first
boom.
Normal capacity
• If the first boom is pressed down, the sensors
indicate a negative pressure and the lifting
capacity is normal during the complete lifting
cycle.
Increased capacity (ADC mode)
• ADC lamps light up.
If the sensors indicate a positive pressure, the
lifting capacity is increased during the com-
plete lifting cycle.
