3 Functions and features
The through-beam sensor detects objects and materials without contact and
indicates their presence by a switching signal.
Range: → type label.

* In the following sections installation and setup are described using the example of the type
with front lens. The functions of the units with side lens are identical.
Secure the receiver (OJELxx) to a bracket.►
Align the transmitter (OJSLxx) to the receiver and secure it in the same way.►
Maximum range is only possible with precise alignment.
Mount the unit so that the mounting position cannot change (avoid high►
vibrations!).
Laser units with a very small light spot diameter are highly focussed; the
slightest change in the mounting position will result in misalignment.
The optical position of the laser beam may deviate slightly from the mechanical
axis. Therefore we recommend using the fine adjustment units E21225 (front lens)
or E21226 (side lens) when mounting the laser units.

6 Setup
The through-beam sensor is supplied ready to operate (plug & play) set at the
max. sensing range. This is sufficient if the through-beam sensor can operate with
maximum excess gain. The following setting procedures should only be necessary
in less straight-forward applications, for example if partly transparent objects must
be detected.

7 Settings
7.1 Setting of the sensitivity with stationary objects*
1
Go into the programming mode of the unit.
Press for about 2 s►
until the red LED flashes.
The red LED goes out; the yellow and green LEDs flash alternately.>
The unit is in the programming mode.>
2
Set the sensitivity with object.
Press once.►
The yellow and green LEDs go out for approx. 1 s, then flash again alternately.>
3
Set the sensitivity without object.
Press once.►
The yellow and green LEDs go out for approx. 1 s.>
After approx. 3 s the green LED is on.>
The unit is in the operating mode.>
Setting steps 2 and 3 can also be carried out in reverse order.
* The sensitivity can also be set in exactly the same way using the programming wire (pin 2 /
WH). To activate the functions the programming wire is connected to L+ (pin 1 / BN) for PNP
units or to L- (pin 3 / BU) for NPN units for the appropriate time. Feedback: If setting was not
successful via the programming wire, the output will switch for 2 s. The unit then passes into
the operating mode with the sensitivity being unchanged.

UK
If the setting of the sensitivity is not possible (e.g. object signal and back-
ground signal are about the same), the red LED flashes after step 3 for ap-
prox. 2 s. The unit then passes into the operating mode with the sensitivity
being unchanged.
If the setting button is not activated for 15 minutes during the programming
process, the unit passes automatically into the operating mode with the
sensitivity being unchanged.
7.2 Setting of the sensitivity with moving objects*
1
Go into the programming mode of the unit.
Press for about 2 s►
until the red LED flashes.
The red LED goes out; the yellow and green LEDs flash alternately.>
The unit is in the programming mode.>
2
Allow objects to pass through the detection area during the measurement (about►
1 s) (number of the objects between min. 8 Hz and max. switching frequency).
Press once.►
The yellow and green LEDs go out for approx. 1 s, then flash again alternately.>
3
Allow objects to pass through the detection area during the measurement (about►
1 s) (number of the objects between min. 8 Hz and max. switching frequency).
Press once.►
The yellow and green LEDs go out for approx. 1 s., after approx. 3 s the green>
LED is on.
The unit is in the operating mode.>

* The sensitivity can also be set in exactly the same way using the programming wire (pin 2 /
WH). To activate the functions the programming wire is connected to L+ (pin 1 / BN) for PNP
units or to L- (pin 3 / BU) for NPN units for the appropriate time. Feedback: If setting was not
successful via the programming wire, the output will switch for 2 s. The unit then passes into
the operating mode with the sensitivity being unchanged.
If the setting of the sensitivity is not possible (e.g. object signal and back-
ground signal are about the same), the red LED flashes after step 3 for ap-
prox. 2 s. The unit then passes into the operating mode with the sensitivity
being unchanged.
If the setting button is not activated for 15 minutes during the programming
process, the unit passes automatically into the operating mode with the
sensitivity being unchanged.
7.3 Setting of the maximum sensitivity*
Go into the programming mode of the unit (→ step 1).►
Interrupt the light beam.►
Press the setting button twice (→ steps 2 and 3).►
* The maximum sensitivity can also be set in exactly the same way using the programming
wire (pin 2 / WH). To activate the functions the programming wire is connected to L+ (pin 1 /
BN) for PNP units or to L- (pin 3 / BU) for NPN units for the appropriate time.
7.4 Electronic lock
Activate the lock by connecting the programming wire for about 15 s -20 s*.
Deactivate the lock by connecting the programming wire again for 15 s - 20 s*.
* To activate the functions the programming wire (pin 2 / WH) is connected to L+ (pin 1 / BN)
for PNP units or to L- (pin 3 / BU) for NPN units for the appropriate time.
7.5 Programming the output function*
Press for 10 s.►
The red LED starts to flash fast after 2 s.>
Then the yellow and green LEDs flash>
alternately.
After 10 s all LEDs go off, the output func->
tion has changed from light-on mode to
dark-on mode (or vice versa).
* The output function can be programmed in exactly the same way using the programming
wire (Pin 2 /WH). To activate the functions the programming wire is connected to L+ (pin 1 /
BN) for PNP units or to L- (pin 3 / BU) for NPN units for the appropriate time.

8 Operation
Check whether the unit operates correctly.►
Display by LEDs.>
Green LED on Unit is ready for operation.
Yellow LED on Output is switched.
Red LED on Error in object detection, e.g. maladjustment, soiling of the lenses
LEDs yellow + red
Flash alternately, 2 Hz: output short-circuited.
Flash alternately, 1 Hz: internal fault.
(output is not switched).
9 Maintenance, repair and disposal
Keep the lenses of the sensor free from soiling.►
For cleaning do not use any solvents or cleaning agents which could damage►
the plastic lenses.
Do not try to open the module enclosure. There are no user - serviceable►
components inside.
