Laser receiver
LR 30
Dimensions (length × width ×
height)
131 × 57 × 29 mm
A) The working range may be reduced by unfavourable environ-
mental conditions (e.g. direct sunlight).
B) Dependent on the distance between the laser receiver and the
rotary laser and on the laser class and laser type of the rotary
laser
C) The reception accuracy may be reduced by unfavourable envir-
onmental conditions (e.g. direct sunlight).
D) Only non-conductive deposits occur, whereby occasional tem-
porary conductivity caused by condensation is expected.
For clear identification of your laser receiver, see the serial number
(10)
on the type plate.
Fitting
Inserting/changing the battery
Alkali-manganese batteries are recommended for the laser
receiver.
Pull the locking mechanism
(11)
of the battery compartment
cover outwards and lift up the battery compartment cover
(9)
. Insert the battery.
Ensure that the polarity is correct.
If the battery becomes weak, an audio signal will sound and
all LEDs will flash. The laser receiver then automatically
switches itself off.
u
Take the battery out of the laser receiver when you
are not using it for a prolonged period of time.
When it
is stored in the laser receiver for longer periods, the bat-
tery can corrode and discharge itself.
Operation
Starting operation
u
Protect the laser receiver against moisture and direct
sunlight.
u
Do not subject the laser receiver to extreme temperat-
ures or variations in temperature.
As an example, do
not leave it in vehicles for longer periods. In case of large
variations in temperature, allow the laser receiver to ad-
just to the ambient temperature before putting it into op-
eration. In case of extreme temperatures or variations in
temperature, the accuracy of the laser receiver can be im-
paired.
Setting up the laser receiver (see figure A)
Place the laser receiver at least
1
m away from the rotary
laser. For rotary lasers with multiple operating modes, select
the horizontal or vertical operation with the highest rota-
tional speed.
Position the laser receiver so that the laser beam can reach
the reception area
(18)
. Align it so that the laser beam runs
straight through the reception area (as shown in the figure).
Switching On and Off
u
A loud audio signal sounds when switching on the
laser receiver. Therefore, keep the laser receiver
away from your ear or other persons when switching it
on.
The loud sound can damage hearing.
To
switch on
the laser receiver, press the on/off but-
ton
(17)
. All LEDs light up briefly and an audio signal
sounds.
Once the laser receiver has been switched on, the audio sig-
nal is switched on and the measuring accuracy is set to "ex-
act".
To
switch off
the laser receiver, press the on/off but-
ton
(17)
again. Before the tool switches off, all the LEDs will
light up briefly.
If no button on the laser receiver is pressed for approx.
6
min and no laser beam reaches the reception area
(18)
for
6
min, the laser receiver will automatically switch itself off to
preserve battery life. Switch-off is indicated by all the LEDs
lighting up briefly.
Selecting the setting of the centre line indicator
You can use the button for adjusting the reception accur-
acy
(16)
to specify the accuracy with which the position of
the laser beam is indicated as "centred" on the reception
area:
–
Reception accuracy "exact":
An audio signal sounds
and the centre line LED
(7)
flashes for confirmation.
–
Reception accuracy "mid-range":
Two audio signals
sound and the LED direction indicators "Laser beam
above centre line"
(8)
and "Laser beam below centre
line"
(6)
flash for confirmation.
Direction Indicators
The position of the laser beam in the reception area
(18)
is
indicated as follows:
– By the direction LEDs "Laser beam above centre line"
(8)
,
"Laser beam below centre line"
(6)
or centre line indic-
ator
(7)
on the front and back of the laser receiver,
– optionally by the audio signal.
Laser receiver too low:
If the laser beam hits the upper half
of the reception area
(18)
, the "Laser beam above centre
line" LED direction indicators
(8)
light up.
If the audio signal is switched on, it will be emitted in a slow
rhythm.
Move the laser receiver upwards in the direction of the ar-
row.
Laser receiver too high:
If the laser beam hits the lower half
of the reception area
(18)
, the "Laser beam below centre
line" LED direction indicators
(6)
light up.
If the audio signal is switched on, it will be emitted as a fast
beeping sound.
Move the laser receiver downwards in the direction of the ar-
row.
Laser receiver centred:
If the laser beam hits the reception
area
(18)
at the height of the centre mark
(15)
, then the
centre line LEDs
(7)
light up.
If the audio signal is switched on, a continuous tone sounds.
Laser Beam Indicator Audio Signal
The position of the laser beam on the reception area
(18)
can also be indicated by an audio signal.
