USER MANUAL UE0009 IFM
Function and features
In conjunction with a prismatic reflector or reflective tape the retroreflective sensor detects objects and materials without contact and indicates their presence by a switched signal.
Range (r): see type label (value referred to prismatic reflector with 80mm ).
Electrical connection
Isolate power, then connect the unit (see page 17 or type label).
Core colours: BN = brown, BU = blue.
Output function light-on or dark-on mode depending on the unit (see type label).
Note: insert a miniature fuse according to the technical data sheet.
Recommendation: check the unit for reliable function after a short cirucit.
Installation
LED red
Fix prismatic reflector / reflective tape in desired position. Align the photocell photocell towards the reflector and fasten it to a mounting bracket; the light spot must hit the prismatic reflector.
Maximum range is only possible with precise alignment.
NB: Commissioning
The retro-reflective sensor is supplied ready to operate (plug and play) set at the max. sensing range. This is sufficient if the retro-reflective sensor can operate with maximum excess gain (highest contrast). The following setting procedures should only be necessary in less straightforward applications, for example if partly transparent objects must be detected.
Setting of the sensitivity with stationary objects
| 1 | Activate the programming mode of the unit. Press for about 2s until the LED flashes. |
| The LED starts to flash rapidly. The unit is in the programming mode as soon as the LED flashes slowly |
| 2 | Set the sensitivity with object. Press once. |
| The LED goes out during the first measuring process. As soon as the LED flashes slowly, the unit is in the programming mode again. |
| 3 | Set the sensitivity without object. Press once. |
| The LED goes out during the second measuring process. If the programming was successful, the unit is now in the normal operating mode. |
You can also proceed in reverse order: first setting without the object, then with the object.
If the setting of the sensitivity is not possible (e.g. object signal and background signal are about the same), the LED flashes after step 3 for approx. 2s. The unit then passes into the operating mode with the sensitivity being unchanged.
Setting of the sensitivity with moving objects
| 1 | Activate the programming mode of the unit. Press for about 2s until the red LED flashes. |
| The LED starts to flash rapidly. The unit is in the programming mode as soon as the LED flashes slowly. |
| 2 | During the measurement (approx. 1s) allow at least two objects to move through the sensing area of the lens. Press once. | |
| The LED goes out during the first measuring process. As soon as the LED flashes slowly, the unit is in the programming mode again. | ||
| 3 | During the measurement (approx. 1s) allow at least two objects to move through the sensing area of the lens. Press once. | |
| The LED goes out during the second measuring process. If the programming was successful, the unit is now in the normal operating mode. | ||
If the setting of the sensitivity is not possible (e.g. object signal and background signal are about the same), the 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.
The output of the unit is switched during the whole programming operation!
Setting of the maximum sensitivity
- Go into the programming mode (step 1).
- Align the unit so that no light is reflected.
- Press the setting button twice (see steps 2 and 3).
Locking / Unlocking
| Press for 10s. | The red LED starts to flash rapidly after 2s. After that the LED flashes slowly for approx. 8s. When the LED goes out the unit is locked. |
| Press for 10s. | → | After 10s the LED goes out, locking is cancelled. |
Operation
Check the safe functioning of the diffuse reflection sensor. Display by LED and by the output.
Units with light-on mode (normally closed)
The unit receives light reflected by the prismatic reflector LED is on, output switched: no object detected (certain range).
The unit receives light reflected by the prismatic reflector LED flashes (1 Hz), output switched:, no object detected (uncertain range).
The unit receives no light reflected by the prismatic reflector LED off, output not switched: object detected.
Units with dark-on mode (normally open)
The unit receives no light reflected by the prismatic reflector LED is on, output switched: object present (certain range).
The unit receives very little light reflected by the prismatic reflector LED flashes (1 Hz), output switched: object present (uncertain range).
The unit receives light reflected by the prismatic reflector LED off, output not switched: no object detected.
Maintenance
Keep the lens of the sensor free from soiling. For cleaning do not use any solvents or cleaning agents which could damage the plastic lenses.
