Mounting the amplifier
Installing the fiber optics
Open the transparent protective cover.
Push down the lever of the fiber optic clamp to open.
Lead the KF/KFX type fiber optics in completely as far as they will go (ca. 12mm deep) into the fiber optic intake.
When doing so, observe the transmitter/receiver assignment on the amplifier (transmitter at bottom / receiver on top).
Pull up the lever of the fiber optic clamp to close. Check if the clamp is secure by pulling lightly on the fiber optics.
Close the transparent protective cover.

The amplifier is mounted as shown on a TS 35 DIN rail while disconnected from voltage.
Alternatively, the amplifier can also be
mounted without a DIN rail using the
mounting accessory (supplied) and
M3 screws.

Menu-driven sensor setting
The LV462 can be adjusted to meet customer requirements with a simple menu-driven system.
To do this, set the selector switch for the operating mode to position PRG.

Switching output
LO: switching output light switching:
if throughbeam fiber optics are installed, the switching output is active when the
light path is free; if a scanning system is installed, the switching output is active
when an object is detected. The status LED illuminates when the switching output
is active.
DO: switching output dark switching:
the switching behavior is the inversion of the light switching setting.
Control buttons
+and
-
Button +: the value in the display is incremented by 1 digit each time the button is pressed.
Button
- : the value in the display is decremented by 1 digit each time the button is pressed.
Note: If a button is kept pressed, the value in the display is continuously changed
in steps of 10.
Indicator
Transmitting power
the first location on the left of the display indicates the set transmitting power
in operating modes RUN and ADJ
H: standard sending pulse length (setting SP-H)
L: long sending pulse for more range (setting SP-L)
Indicator
Switching threshold
the 3 locations to the right of the screen indicate the set switching threshold in
operating modes RUN and ADJ (value range: 000 … 999).
sepending on the setting LO / DO, the sensor switches when the set switching
threshold value is undershot or overshot.

Only one of the four possible time functions can be activated at any given time. First select the required function and then
assign a delay time to it.

Adjusting the operating range
Menu functions sending pulse length and sending pulse power are used to adjust the range.
Setting in the menu:
SP-L / Po-2 maximum operating/scanning range (extra long range)
SP-L / Po-1 or SP-H / Po-2 medium operating/scanning range (long range)
SP-H / Po-1 minimum operating/scanning range (standard range)
Recommended settings:
Adjusting the switching threshold
To set the switching point, the switching threshold must be set.
To set the switching threshold, set the selector switch for the operating mode to the ADJ position.
The switching output is active when
the switching threshold in the light switching setting (LO) is overshot by the reception signal in the sensor.
the switching threshold in the dark switching setting (LD) is undershot by the reception signal in the sensor.
Setting the switching threshold using the AutoSet function
(based on the example of a scanning system - a throughbeam system is set analogous to this)
Manual adjusting of the switching threshold
If the selector switch for the operating mode is in the ADJ, position, the switching threshold can be set manually.
Button +: The switching threshold in the display is incremented by 1 digit each time the button is pressed.
Button
+ : The switching threshold in the display is decremented by 1 digit each time the button is pressed.
If a button is kept pressed, the value in the display is continuously changed in steps of 10.

Remarks:
The sensor is optimally set when the displayed switching threshold is 50 … 100 digits.
If the displayed value is smaller, reduce the range. If the value shown is near to setting limit 999, then set a higher range.
If, at a displayed value of 999, the status LED is not ON, then the range is too
low.
Check the range setting, reduce the object distance.
If, at a displayed value of 999, the status LED is not OFF, then the range is
too low.
Check the range setting, reduce the object distance.
