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
effected using M3 screws
through the fixing holes 


provided.
Toremove 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:
Wheninserting the optical fibers,
the resistance of the device’s in-
ternal O-ring seal must be over-
come.
The optical fibers must be fed
right to the stop without fail.
The optical fibers must not be
crushed.
The sequence (emitter /
receiver) is usually immaterial,
however:
With coaxial optical fibers, the
optical fiber bundle  must be
connected on the receiver side
. The emitter and receiver
openingsare markedwith arrows
on the housing.

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 approximately 80% of the darkening created by the target
triggers the switching process.


Diffuse sensors : Remove target, leave or place background in
position.
Through-beam sensors : Leave or place target in position.

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.

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.

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.


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.
According to the type (above all
for thin-fiber executions), prior
twisting helps.
Optical fiber mounting
(All diameters refer to the optical
diameter.)
No bending should occur in zone
“A”.
