Correction of Malfunctions
Malfunctions with Error Codes
The error code of a malfunction is shown on the display.
– Rectify the malfunction (see “Corrective Measure”).
– Afterwards, simultaneously press the centre line mode button 19 and audio signal/volume button 24.
If the malfunction was successfully rectified, the error code indication goes out and automatic levelling will
start (see “Automatic Levelling during Operation”, page40).
If the malfunction persists, have the measuring tool checked by a Bosch customer service agent.
Error Code
Indication
Problem
Corrective Measure
001
The X-axis of the measuring tool is outside of
the self-levelling range of approx. 8.5 %
(5°).
– Reposition the measuring tool along the X-axis.
002
The Y-axis of the measuring tool is outside of
the self-levelling range of approx. 8.5 % (5°).
– Reposition the measuring tool along the Y-axis.
003
(GRL500 HV)
The Z-axis of the measuring tool in vertical
mode is outside of the self-levelling range of
approx. 8.5 % (5°).
– Reposition the measuring tool in vertical mode along the
Z-axis.
004
Measuring tool is at a slant of more than
8.5 % after a position change.
– Reposition the measuring tool.
The slope range of ±8.5 % has been ex-
ceeded in single-axis slope operation.
– Press the slope button 18 or 20 until a slope value of less than
8.5% is shown on the display (see “Slope Setting”, page40).
005
Duration of automatic levelling has been ex-
ceeded. Measuring tool cannot be levelled in.
– Place the measuring tool on a stable surface or mount it in a sta-
ble manner on a tripod. The environment must be vibration-free.
006
The desired slope is not reached in single-
axis slope operation.
– Place the measuring tool on a stable surface or mount it in a sta-
ble manner on a tripod. The environment must be vibration-free.
007
The rotation head of the laser is not rotating. – Simultaneously press the centre line mode button 19 and au-
dio signal/volume button 24.
– Switch the measuring tool off (see “Switching Off”, page38).
– Switch the measuring tool back on.
008
During the search in centre line mode, the la-
ser beam reaches the end of the pivoting
range without finding the reception area of
the laser receiver.
– Check whether the visual contact between measuring tool and
laser receiver has been interrupted and reposition the meas-
uring tool if necessary.
If the error continues to occur, reduce the distance between
measuring tool and laser receiver.
009
External influences (e.g. falls or heavy im-
pacts) are interfering with centre line mode.
– Reposition the measuring tool.
Place the measuring tool on a stable surface or mount it in a sta-
ble manner on a tripod. The environment must be vibration-free.
– Restart the search to find the centre line (see “Centre Line
Mode”, page40).
Ensure that the pivoting range of the laser beam is not interrupt-
ed by persons or other visual obstacles during the search.
If the error continues to occur, reduce the distance between
measuring tool and laser receiver.
020
General error
– Simultaneously press the centre line mode button 19 and au-
dio signal/volume button 24.
– Switch the measuring tool off (see “Switching Off”, page38).
– Switch the measuring tool back on.
033
Ambient light is too bright for the laser
receiver.
– Shade the reception area.
