Dig Mode
When the machine is not being used as a crane, it may be permitted for the system to operate in DIG
mode. In DIG mode all overload warnings and motion cut on overload is turned
OFF
, and no protection
against overload will be present. The blue light on the roof will be turned off, and where red / white
indicator lamps are present the white lamp will switch
OFF
and the red lamp will switch
ON
. The data log
will record the use of DIG mode. In order to use DIG mode, the foreman key switch must be in the
unlocked
position.
To engage DIG mode, press the
[MENU]
button, and press the
[DIG IS OFF]
button. DIG mode will then be
turned on. The main screen will indicate that DIG mode is engaged by turning the DIG mode indicator to
green
(item 3 on page 5)
, a yellow circle with an alarm symbol with a cross will be shown next to the
logging symbol top right of the screen and
LOGGING DIG MODE
will flash in the status bar
(item 8 on
page 5)
.
To turn DIG mode off and return to LIFT mode, press the
[MENU]
button and then press the
[DIG RAIL
MODE]
button at the top right of the screen.
Backward Stability
The RCI system will monitor the state of the machine to prevent the machine falling over backwards
when working on a cant. With a reduced load on the hook and when working on a cant of more than
50mm with the turret facing up the cant, the RCI may restrict the movement of the stub boom back.
When the maximum boom angle is achieved in a potentially backwardly unstable condition the stub
boom lift function will be motion cut and a
“
backward stability
”
message will be shown. If the boom is far
enough back to trigger a backwardly unstable condition and the machine is slewed towards a potentially
backwardly unstable condition, the
“
backward stability
”
message will be shown and the slew function
will be cut to prevent the machine reaching a backwardly unstable position. To rotate the turret further,
lower the stub boom until the message disappears and slew function is restored.
Height Limits
In order to set a height limit, the foreman key switch must be in the
unlocked
position.
To set a height limit, press the
[MENU]
button and then press the
[HEIGHT LIMIT is off]
button.
The system will ask if you wish to Enter a height limit. To enter a height limit (in meters) press
[YES]
.
To capture a height limit from the excavator current boom position, press
[NO]
and you will be prompted
to move the excavator to the desired height limit and press
[YES]
. A height limit will be set that
corresponds with the highest point of the excavator at the moment it was set. Once set, the RCI will
monitor all booms against the set height limit, and will motion cut any hydraulic service that will cause a
boom to move through a set height limit. Services that cause machine movement away from the height
limit will always be allowed.
To turn off a set height limit press
[MENU]
and the
[HEIGHT LIMIT IS ON]
.
The height limit will be turned off.
