Safety notes

Read the operating instructions before starting operation.
Connection, assembly, and settings only by competent technicians.
Protect the device against moisture and soiling when operating.
No safety component in accordance with EU machine guidelines.

Risk group 1

UV-light emitted from this product.
Do not stare at operating lamp.

Correct use

The luminescence sensor LUT9 is an optoelectronic sensor and is used for optical, non-contact detection of fluorescent test objects.

Starting operation

Starting operation - Part 1
Starting operation - Part 2

Equipment plug horizontally (H) and vertically (V) adjustable.
Connect and secure cable receptacle tension-free. The following apply for connection in B: brn = brown, blk = black, blu = blu, wht = white, gra = grey. Outputs: Q_PNP , Q_NPN or Q_A = analog output or C / Q = IO link.
Connect the sensor according to the B connection chart.
Mount sensor with mounting holes to a suitable fixture and align it. Pay attention to sensing range for this (see the technical data at the end of these operating instructions and the chart, x = sensing range, y = relative sensitivity, SW = switching threshold).
Align the horizontal and vertical movements of the test object using correspondingly long markings.
Connect sensor to operating voltage (see nameplate).
The first LED of the bar chart lights up.
Manufacturer's setting: max. sensitivity, bright switchover.
Teach-in function:
Set selector knob to "TEACH". Set bright and dark switchover via Teach-in sequence. The yellow switch-output diode lights up when a luminescent test object is detected.
1. First Teach-in operation:
  Move luminescent mark or background into the light spot. Press the Teach-in button. The transmitting light, the bar graph and the switch-output diode flash slowly.
2. Second Teach-in operation:
  Move luminescent mark or background into the light spot. Press the Teach-in button. The bar graph glows continuously. If the transmitting light and the switch-output diode flash, the difference in luminescence between mark and background was too low.
  Bar graph:
  Quality of Teach-in. The more LEDs light up, the better the Teach-in operation. If the sensor is manually adjusted, no prediction of detection reliability is possible.
3. 1 LED lights up:
  Unreliable teach-in. Stabilisation of operation: observe quality of luminescence and sensing distance. Readjust or clean sensor or carry out fine adjustment manually.
4. 2–4 LEDs light up:
  Teach-in sufficient, sufficient luminescence or difference present.
5. > 4 LEDs light up:
  Reliable teach-in
Manual fine adjustment, increase or decrease sensitivity:
Turn selector knob to "+" or "–" and press Teach-in button.
The bar chart indicates sensitivity.
To trigger switching operation, output Q changes status if the necessary intensity of luminescence is too high or too low. 2 x press is equivalent to shifting one segment. The maximum degree of sensitivity is achieved at 10 sec. Lock the Teach-in button with "RUN" to prevent it being pressed accidentally. The bar graph indicates the intensity of luminescence.
Set evaluation mode:
Set selector knob to "MODE" and press Teach-in button.
HR = high-resolution mode for low intensity of luminescence and long response time.
S = standard mode for standard applications.
HS = high-speed mode for high intensity of luminescence and short response time.
The luminescence intensity is displayed in evaluation mode.
Selector switches one position forward for each press of the button. The last setting is saved.
Setting delay in switch-off:
Turn selector knob to "TIMER" and press Teach-in button. The bar graph indicates the time-step set. Selector switches one position forward for each press of the button. The last setting is saved.
Lens replacement:
The screwed-in lens can be replaced by another lens. Sensing distances: 10 / 20 / 50 / 90 mm.
Reset:
Set selector knob to "MODE" and press Teach-in button > 5 sec.

Maintenance

SICK sensors are maintenance-free.
We recommend doing the following regularly:

clean the external lens surfaces
check the screw connections and plug-in connections. No modifications may be made to devices.
