Working With Automatic Levelling - CST/BERGER LM800 Serie Manual Original

Working with Automatic Levelling

LM800GR
After switching on, the measuring tool automatically
detects the horizontal or vertical position. To change
between the horizontal and vertical position, switch
the measuring tool off, reposition it and switch on
again.
Note: Working with automatic levelling is only possi-
ble when the measuring tool is in the horizontal posi-
tion.
After switching on, the measuring tool checks if it was
set up in horizontal or vertical position. In horizontal
position, it automatically compensates irregularities
within the self-levelling range of ± 5°.
When the measuring tool is inclined by more than 5°
after switching on or after a position change, levelling
is no longer possible. In this case, the rotor is stopped
and the laser is switched off. When the grade along-
side the Y-axis is too large, the shock-warning indica-
tor 9 lights up and the indicator for working without
automatic levelling 7 flashes. When the grade along-
side the X-axis is too large, the shock-warning indica-
tor 9 flashes and the indicator for working without
automatic levelling 7 lights up.
In this case, switch the measuring tool off, re-align it
and switch the measuring tool on again. If the measur-
ing tool is not re-positioned, it is automatically
switched off after 2 minutes.
When the measuring tool is levelled in, it continuously
checks the horizontal position. Automatic re-levelling
takes place after position changes. If the measuring
tool can not be re-levelled after 3 seconds, the rotor is
stopped during the levelling procedure to avoid faulty
measurements, and the laser flashes. The shock-
warning function remains active.
LM800DP
After switching on, the measuring tool automatically
detects the horizontal or vertical position. To change
between the horizontal and vertical position, switch
the measuring tool off, reposition it and switch on
again.
After switching on, the measuring tool checks the hori-
zontal and vertical position, and automatically compen-
sates irregularities within the self-levelling range of ± 5°.
When the measuring tool is inclined by more than 5°
after switching on or after a position change, levelling
is no longer possible. In this case, the rotor is stopped
and the laser is switched off. When the grade along-
side the Y-axis is too large, the shock-warning indica-
tor 9 lights up and the indicator for working without
automatic levelling 7 flashes. When the grade along-
side the X-axis is too large, the shock-warning indica-
tor 9 flashes and the indicator for working without
automatic levelling 7 lights up.

In this case, switch the measuring tool off, re-align it
and switch the measuring tool on again. If the measur-
ing tool is not re-positioned, it is automatically
switched off after 2 minutes.
When the measuring tool is levelled in, it continuously
checks the horizontal and vertical position. Automatic
re-levelling takes place after position changes. If the
measuring tool cannot be re-levelled after 3 seconds,
the rotor is stopped during the levelling procedure to
avoid faulty measurements, and the laser flashes. The
shock-warning function remains active.
Shock-warning Function
The measuring tool has a shock-warning function;
after position changes or shock to the measuring tool,
or in case of ground vibrations, it keeps the measuring
tool from levelling in at changed heights, and thus pre-
vents vertical errors.
LM800GR: As the shock-warning function is con-
nected to the automatic levelling, this function is only
active when the measuring tool is in the horizontal
position (independent of the shock-warning indicator
9 being lit).
LM800DP: The shock-warning function is active both
in horizontal and vertical position of the measuring
tool.
When factory set, the shock-warning function is acti-
vated after switching on the measuring tool (shock-
warning indicator 9 lit). The shock warning is activated
approx. 60 s after switching on the measuring tool or
switching on the shock-warning function.
When the levelling-accuracy range is exceeded after
a position change of the measuring tool or when
heavy ground vibrations are detected, the shock-
warning function is actuated:
The rotation is stopped, the laser and the shock-warn-
ing indicator 9 flash. The current operating mode is
stored.
After the shock warning has actuated, press the
shock-warning button 10. The shock-warning function
is restarted and the measuring tool starts the levelling.
As soon as the measuring tool is levelled in, it starts in
the stored operating mode. Now, check the height of
the laser beam with a reference point and correct the
height, if required.
To switch off the shock-warning function, press
shock-warning button 10 once, or, when the shock
warning has actuated (shock-warning indicator 9
flashing red), press it twice. When the shock warning
is shut off, the shock-warning indicator 9 goes out.
The shock-warning function can also be set in such a
manner that it is not automatically switched on when
switching on the measuring tool. Switching on the
function at a later point of time is of course possible.
