MLV11 Series - Introduction
- Operating mode:
(Only for sensors with light guide
connection MLV11-LL...)
Some of these settings are not avail-
able on through-beam sensors and
are only possible on the receiver:

• Direct detection

Pulse frequency
Emitter disconnection
The emitter is equipped with a test input (switches emitter off).
-Manually(using the membrane keys)
- Automatically (TEACH-IN)
Note:
The sensitivity adjustment (teach in or manually) is maintained even after the oper-
ating voltage is turned off.
Sensitivity / adjustment using the membrane keys
On delivery, the sensitivity of the photoelectric sensor is set to maximum over the
whole operating distance of 0 m ... 15 m. It is possible via the membrane key to
achieve the detection of material with partial optical absorption (detection of partly
transparent or small objects) or to reduce the effective operating distance (improve-
ment of the interference light suppression).
A useful adjustment can be achieved in the 2 m ... 15 m range. In this range, the
automatic adjustment (TEACH-IN) ensures a function with optimum signal reserve.
Manual adjustment
1) Align the emitter and receiver correctly. The light path must be unobstructed.
2) If necessary, simultaneously push the "+" and "-" buttons for 5 seconds until
the green LED flashes once. The sensor is now unlocked.
The light path must be unobstructed!
3) Using the "+" and "-" buttons, the sensitivity of the sensor can be adjusted (the
red LED flashes with each keystroke, the yellow LED indicates the switching
status).
The push buttons feature a repeat function: simply hold down the key for re-
peated actuation. The sensitivity adjustment is maintained even after the op-
erating voltage is turned off.
Note:
If the red LED does not flash when the key is pushed, then the sensor is either
at the end of the adjustable range or the keypad is locked.

EmitterReceiver
Automatic Adjustment (Dynamic Mode for Moving Targets)
1) Align the emitter and receiver correctly. The light path must be unobstructed.
2) If necessary, simultaneously push the "+" and "-" buttons for 5 seconds until
the green LED flashes once. Release the keys briefly. The sensor is now un-
locked.
The light path must be unobstructed!
3) Simultaneously push the "+" and "-" buttons (approx. 2 s) until the green LED
flashes, then release both keys. The sensor is now in the TEACH-IN mode as
indicated by the green LED flashing at 2 Hz.
4) The teaching process has finished when the green LED remains on.

Manual adjustment
1) If necessary, simultaneously push the "+" and "-" buttons for 5 seconds until
the green LED flashes once. The sensor is now unlocked.
2) Place the object to be detected at the desired distance within the sensing
range. Using the "+" and "-" buttons, the sensitivity of the sensor can be ad-
justed (the red LED flashes with each keystroke, the yellow LED indicates the
switching status).
The push buttons feature a repeat function: simply hold down the key for re-
peated actuation.
Note:
If the red LED does not flash when the key is pushed, then either the sensor
is at the end of the adjustable range or the keypad is still locked.

TEACH-IN of moving objects (dynamic TEACH-IN)
1) If necessary, simultaneously push the "+" and "-" buttons for 5 seconds until
the green LED flashes once. The sensor is now unlocked.
2) Simultaneously push the "+" and "-" buttons (approx. 1 s) until the red LED
goes out. The sensor is now in the TEACH-IN mode as indicated by the green
LED flashing at 2 Hz.
Note:
If the red LED does not flash when the key is pushed, then the keypad is still
locked.
3) Move the objects to be detected (one object is sufficient) across the sensing
range at the desired distance. The green LED flashes briefly at a higher fre-
quency (4 Hz).
When the LED flashes again at the initial frequency, with an object within the
detection range, the teaching process has finished .
Note:
The very brief change in flashing frequency is undetectable under certain cir-
cumstances.
4) Press either "+" or "-" key to end the TEACH-IN. The sensor then resumes nor-
mal operation.

TEACH-IN of stationary objects (static TEACH-IN)
1) If necessary, simultaneously push the "+" and "-" buttons for 5 seconds until
the green LED flashes once. The sensor is now unlocked.
2) Place the object to be detected at the desired distance within the sensing
range.
Simultaneously push the "+" and "-" buttons (approx. 1 s) until the red LED
goes out. The sensor is now in the teach mode as indicated by the flashing
green LED.
Note:
If the red LED does not flash when the key is pushed, then the keypad is still
locked.
3) The green LED flashes briefly at a higher frequency (4 Hz). When the LED
flashes again at the initial frequency of 2 Hz, the teaching process has fin-
ished.
4) To end the TEACH-IN process, use either the "+" or the "-" key. The sensor
then resumes normal operation.
