Operation Selector Switch
When the selector switch is in the RUN position (see following
example), the sensor will function normally, and all settings
are locked from adjustment. The SET position unlocks the
sensor’s settings, allowing the user to either adjust the sensor
manually, or use the self-teach functionality. When
adjustments are complete, return the switch to the RUN
position (settings become locked). If a manual sensitivity
adjustment is required a user can unlock this setting by
(quickly) switching from RUN to SET to RUN. The sensor will
display a flashing “S” on the LCD display, and the user can
now adjust the sensitivity setting. The sensor will automatically
return to the locked condition 10 seconds after sensitivity
adjustment is complete.
Locking
Two Adjustment Buttons
The red button is used to teach the sensor, change the
frequency and to increase the sensitivity.
The black button is used to change the operating mode,
indication mode and to decrease sensitivity.
Both buttons are inactive in the RUN mode.
Mounting the Sensor
How to Attach Sensor to DIN Rail
Attach front hook of the photoelectric
sensor onto rail (or Mounting bracket)
and press rear end of sensor down
until unit snaps into place.
How to Detach Sensor from DIN Rail
Pushing the sensor unit forward,
pull up on the front of the sensor
until the front hook is detached.
Remove sensor.
Side Mounting Sensor with Bracket
Fasten mounting bracket assembly
using M3 screws. Tightening torque is
0.8Nm max. Attach front hook of the
photoelectric sensor onto mounting
bracket and press rear end of sensor
down until unit snaps into place.

For installation of smaller fiber
optic cables with jacket
diameters of 0.05mm (1.25in)
adaptors are provided for easy
installation.
Wiring the Sensor
Choice of Power Bus, 2m (6.5ft) cable, or 4 pin pico QD
connector are provided for wiring the 45FVL Series sensors.
On the pico QD models Rockwell Automation/Allen-Bradley
recommends the use of the 889 Series cordsets and
patchcords (i.e., 889P–F4AB–2). Standard 2m (6.5ft) cable
lengths are provided with flying leads for hard wiring. Hard
wiring color coding and pin assignment for QD connectors are
as specified below.

The Power Bus option utilizes PB quick disconnect cordsets
which are prewired with up to four conductors. When ganging
sensors with the Power Bus option a three conductor cordset
is wired to one sensor to provide power to all ganged units.
The remaining ganged units use a single conductor cordset
for wiring an output. This option eliminates two conductors per
ganged unit (see below).

Configuring and Using the Sensor
This section will run through the basics on how to operate
your new 45FVL Series sensor. After connecting power, load,
and fiber optic cables the next step is to choose one of two
available options for your Display Mode: Absolute Sensing
Mode or Relative Sensing Mode.
Absolute Sensing Mode measures the absolute value of a
target’s reflected light at that moment represented in a four-
digit value ranging from 0 to 1023. Depending on the
reflectivity of the target 1 of 8 sensitivity level settings (with
1023 bits of resolution) is automatically chosen by the sensor
when target is taught. A “1,” representing the lowest sensitivity
level, would be displayed for a highly reflective target. A “8,”
representing the highest sensitivity, would be displayed for
dull, less reflective targets (see following diagram).
Sensitivity Level (A solute sensing mode)
Incoming Light Level shown in 4 digits
Min = 0 Max = 1023
Relative Sensing Mode monitors and displays the variation
of light received relative to the standard value at which it was
learned. In this mode the sensor measures and learns the
level of light reflected from a target. However, this value is
registered as “0” on the display when target is taught and all
subsequent measurements are relative to that standard value
+/– 1023 bits.
This mode is beneficial in applications to obtain the detailed
light attenuation rate due to soil/damage on the fiber end. See
diagram below.
