These proximity switches must not be used
in applications where the safety of people is
dependent on their functioning. Terms of deli-
very and rights to change design reserved.
Device mounting
Mounting of the device is most
easily effected by snapping /
onto a top-hat rail (according
to DIN / EN 50022).
Alternatively, fixing can be effect-
ed using M3 screws through the
fixing holes provided.
To remove the device from the
rail, push towards the optical
fiber , and lift .
Fixing the optical fibers
Lift catch .
Insert the optical fibers through
the two holes provided into
the device.
Lower catch .
Important:
When inserting the optical
fibers, the resistance of the
device’s internal O-ring seal
must be overcome.
The optical fibers must be fed
right to the stop without fail.
The optical fibers must not be
crushed.
The sequence (emitter / re-
ceiver) is usually immaterial,
however:
With coaxial optical fibers (LFP-
1003-020), the optical fiber
bundle must be connected
on the receiver side . The
emitter and receiver openings
are marked with arrows on the
housing.

Cutting the optical fibers
Cut synthetic optical fibers to
the desired length. Use only
the cutting tool delivered with
the optical fibers.
A maximum of 3 cuts should be
made per cutting-tool hole.
Separating the optical fibers
Grasp the optical fiber ends
with both hands and pull both
strands apart to a length of
about 50 mm.50 mm.
According to the type (above
all for thin-fiber executions),
prior twisting helps.

diameter.)

Setting of the sensing range (teach) is carried out in one cycle, and can be
manually fine adjusted at any time (using the Adjust function, see below).
Diffuse sensors : Teach only takes place on the background.
The target is not taken into consideration. The device adjusts itself
automatically to approximately 80% of the background distance.
Through-beam sensors : Teach is effected with a target located
in the beam. The device automatically adjusts itself so that appro-
ximately 80% of the darkening created by the target triggers the
switching process.
Diffuse sensors : Remove target, leave or place background in posi-
tion.
Through-beam sensors : Leave or place target in position.
Activate Teach 1 mode by pressing the Mode key twice.
Press / Enter key. Teach successful: The Status LED blinks green for
5 seconds. The device is ready for use.
Setting of the sensing range (teach) is carried out in two cycles, and can be
manually fine adjusted at any time (using the Adjust function, see below).
Diffuse sensors : Teach is effected firstly on the target, then
on the background. The device automatically adjusts itself to a
distance between that of the target and that of the background.
Through-beam sensors : Teach takes place firstly without
the target, then with the target located in the beam. The device
automatically adjusts itself to part of the darkening created by the
target.
Diffuse sensors : Position (or leave) target and background.
Through-beam sensors : Remove target.
Activate Teach 2 mode by pressing the Mode key 3 times.
Press / Enter key, the first cycle begins. Teach successful: The Status
LED lights up green. The device is ready for the second cycle.
Diffuse sensors : Remove target, leave background in position
Through-beam sensors : Position target.
Press / Enter key, the second cycle begins. Teach successful: The
Status LED blinks green for 5 seconds. The device is ready for use.
The detection zone can be set manually, or when set by the teach function,
can be manually fine adjusted. All activated functions (except delay and
stretch) are in operation, and the output switched.
Activate Adjust mode by pressing the Mode key 4 times.
For each press on the / Time key, the current detection zone is increased
by 1 increment.
For each press on the / Enter key, the current detection zone is reduced
by 1 increment.
Return to working mode by pressing the Mode key.
Switching of the output is delayed by the set time. In this way, short-term
disturbances can be suppressed. All activated functions (except delay and
stretch) are in operation, and the output switches.
Activate Delay mode by pressing the Mode key 5 times.
Pressing the / Enter key switches the delay (factory setting: 10 msec)
on or off. The current status is shown by the Status LED (green = Delay
switched on).
Each time the / Time key is pressed, the delay time is increased by 10
msec, up to a maximum of 150 msec.
Return to working mode by pressing the Mode key.
Switching of the output is stretched by the set time. In this way, even short
pulses can be detected. All activated functions (except delay and stretch)
are in operation, and the output switches.
Activate Stretch mode by pressing the Mode key 6 times.
Pressing the / Enter key switches the stretching (factory setting: 10
msec) on or off. The current status is shown by the Status LED (green =
Stretch switched on).
Each time the / Time key is pressed, the stretch time is increased by
10 msec, up to a maximum of 150 msec.
Return to working mode by pressing the Mode key.
Setting of the output function (factory setting Light-ON, i.e. light switching
in operation as diffuse sensor, dark switching as through-beam sensor).
Activate Light-ON mode by pressing the Mode key 7 times. The current
status is shown by the Status LED (Light-ON LED off / Dark-ON
LED on).
Pressing the / Enter key changes the output function.
Return to working mode by pressing the Mode key.
