RUN operating mode - normal operation
The RUN operating mode is the standard operating mode in which the sensor detects objects; it signals this
according to the set functions. If the selector switch for the operating mode is in the RUN position, no changes
can be made on the device. This setting is thus suitable for protection against unintended operation and
changes to device settings.
PRG operating mode - sensor adjustment
The LV463 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.
The menu consists of 13 successive subfunctions. Rock to right or left to freely navigate through the subfunctions.

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.

The response time is the max. time required by the switching output to
switch to the active state following a signal change at the input.
From this, the switching frequency can be calculated as follows:
Notice: A change to the response time is equivalent to a change to the
signal range.

shows the current signal value.
The gain stage should be selected so that the signal value is approximately
in the middle of the display area.
If Auto GAIn is selected, the device automatically determines the optimum
gain setting during teaching.

To trigger the teach event, see Teaching operating mode.
1-point teach, static: during teaching, the current signal value is accepted
as the new switching threshold. Actuate the rocker push button to make fine
adjustments to the threshold.
2-point teach, static: the switching threshold is calculated at approximate-
ly midway between two signal values, e.g., teach to two different objects or
teach to the same object at two different distances from the probe. Example:
signal value 1 = 100digits, signal value 2 = 400digits
Switching threshold = 280 digits. Actuate the rocker push button to +or
- to make fine adjustments to the threshold.
Dynamic teach: suitable for processes that cannot be stopped for teaching.
When the teach event is started, the sensor begins to scan the signal values.
On the left, red display, the signal values are constantly displayed. At the end
of the teach event, the switching threshold is calculated at approximately
midway between the smallest and largest signal value.

The function is only available during dynamic teaching. If the function is
switched on, the switching threshold is automatically and continuously
optimized by the sensor in such a way that maximum functional reliability is
ensured.
This can be used to compensate for, e.g., soiling or process changes.
Warning message:
thr ALrt: The limit of threshold tracking is reached - the sensor contin-
ues to operate. Cleaning and, if necessary, alignment of the
fiber optics recommended.
Error message:

(pin 2/ws-WH) are connected to one another. The master unit
(defined with the next subfunction) generates a timing signal
that is received by the slave units (defined with the next
subfunction) via the parallel connection. In a fixed time frame,
each slave successively activates its transmitter for a brief
time and supplies a signal value. To avoid mutual interfer-
ence, the transmitter is then again deactivated.

Combining timing functions
Timing functions can only be combined to a limited extent. Impermissible combinations are suppressed from the subfunctions
menu. Here is an overview of the permissible combinations (•):
Teaching operating mode
Set the selector switch for the operating mode to the ADJ position.
Depending on the setting of the Select teach mode subfunction (tch SEL), one of the following teach modes
appears:
Static 1-point teach
Static 2-point teach
Dynamic teach
Teach process
Tip!
For reliable function, the difference between the signal value while an object is present and the signal value with no object should
be at least 10 - 20%. In general: the larger the difference, the more reliable the detection.

Multiplex operation of multiple amplifiers
If multiple light axes are arranged close to each other, mutual interference – made evident by a widely varying display – may occur.
To avoid this undesirable behavior, up to six devices can be operated in multiplex operation. To do this, it is only necessary
to connect the multi funct multifunction inputs (pin 2/ws-WH) of all participating amplifiers – in addition to connecting the voltage
supply and the switching signal.

The master also requires information about the number of units wired in
parallel (number of slaves).
Each slave is also assigned an individual address 1 … 5.
The master generates a timing signal on pin 2 or on cable ws/WH.
Each slave switches on its transmitter for 1ms depending on its address.
In multiplex mode, the cycle time is based on the total number of units:
Cycle time = number of units • 1.5ms + 0.5ms.

The line teach that is executed is determined in the Select teach mode subfunction tch SEL.
Depending on the setting, this may be a static 1-point teach, static 2-point teach or dynamic teach.

Before teaching:
LOW level =
Selector switch Operating mode un-
locked
HIGH level =

locked
Signal change is only necessary if
a HIGH signal is applied before the teach event.
Action starts with the
rising edge:
tTeach = 20 … 80ms
Selector switch Oper-
ating mode locked
The teach event starts with the falling
edge.
1. Static 1-point teach:
The current signal value is accepted as
the teach value with the falling edge.
2. Static 2-point teach:
The current signal value is accepted as
teach value 1 with the falling edge.
3. Dynamic teach:
The sensor begins scanning the signal
values with the falling edge.
Notice: The sensor has no timeout in teach
mode until the next rising edge.
The teach event is concluded with the ris-
ing edge:
1. Static 1-point teach:
No further action.
2. Static 2-point teach:
The current signal value is accepted
as teach value 2 with the rising edge.
3. Dynamic teach:
Scanning of the signal values is con-
cluded with the rising edge.
900ms after the rising edge, the teach
event is concluded and the sensor
resumes normal operation.
If it should again be possible to operate
the operating mode selector switch, a
LOW signal must be applied. The switch
can again be operated 500ms after the
falling edge.
Remarks:
• During the line teach, the
content of the two displays cor-
responds to the description for
manual teach.
• The line teach starts with the
first rising edge on the teach in-
put independent of the position
of the operating mode selector
switch.
