USER MANUAL OJ5193 IFM

Core colours: BN = brown, BU = blue, BK = black, WH = white. Programming of the output function by push button or programming wire (see page 12). Installation

• In the following sections installation and set-up are described using the example of the type with front lens. The functions of the units with side lens are identical.

teachAlign the photocell and fasten it to a mounting fixture. Mounting of the series OJ51xx The units of the OJ51xx series have two fixing holes on the side for mounting. A mounting fixture is not supplied. Maximum range is only possible with precise alignment. The objects to be detected are to move tranversally to the lens of the unit. In case of other directions of movement it should be tested before whether safe functioning is guaranteed. For demanding applications (small distance between the object and the background) we recommend the following mounting positions:

• In case of shiny background surfaces and less shiny object surfaces the sensor should be mounted vertically to the background surface.

• In case of shiny object surfaces and less shiny background surfaces the sensor should be mounted at an angle of appox. 5 - 10°. ENGLISH

shiny background shiny object approx. 5 - 10°Installation of the supplied mounting fixture Secure the mounting fixture with the screws supplied, then slide the unit into the slot of the fixture until the spring clicks home. To remove the unit press the spring down with a screwdriver and slide the unit out. 10Setting of the sensitivity with stationary objects* You can also proceed in reverse order: first setting without the object, then with the object.

• 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 for the appropriate time to L+ (pin 1 / BN) for PNP units or to L- (pin 3 / BU) for NPN units. Feedback: If set- ting was not successful via the programming wire, the output will switch for 2s. The unit then reverts to the operating mode with the sensitivity unchanged. ENGLISH

Press for about 2s until the red LED flashes. Activate the programming mode of the unit. The red LED goes out; the yellow and green LEDs flash alternately. The unit is in the programming mode.

Setting with object. Press once. The yellow and green LEDs go out for approx. 1s, then flash again alternately.

Press once. The yellow and green LEDs go out for approx. 1s, after approx. 3s the green LED is on. The unit is in the operating mode.

etting without object. The background must be within the maximum range.If the setting of the sensitivity is not possible (e.g. object signal and background signal are about the same), the red LED flashes after step 3 for approx. 2s. 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. Setting of the maximum sensitivity*

• Go into the programming mode (step 1).

• Align the unit so that no light is received by the object or the back- ground (min. distance > max. range).

• Press the setting button twice (see steps 2 and 3).

• The maximum sensitivity can also be set in exactly the same way using the program- ming wire (pin 2 / WH). To activate the functions the programming wire is connected for the appropriate time to L+ (pin 1 / BN) for PNP units or to L- (pin 3 / BU) for NPN units. Electronic lock Activate the lock by connecting the programming wire for about 15s – 20s*. De-activate the lock by connecting the programming wire again for 15s – 20s*.

• 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. Programming the output function*

• The output function can be programmed in exactly the same way using the program- ming wire (pin 2 / WH). To activate the functions the programming wire is connected for the appropriate time to L+ (pin 1 / BN) for PNP units or to L- (pin 3 / BU) for NPN units.

Press for 10s. The red LED starts to flash fast after 2s. Then the yellow and green LEDs flash alternately. After 10s all LEDs go off, the output function has changed from light-on mode to dark-on mode (or vice versa).Operation Check the safe functioning of the unit. Display by LEDs. Maintenance Keep the lens of the sensor free from soiling. ENGLISH
