6.3 Dynamic Teach – with Running Conveyor Belt
The sensor is taught in such that, depending on the application, minimal thresholds can be set in order to
detect smallest possible parts by means of this process. With running conveyor belt, the sensor is set to a
signal analysis phase which lasts for 10 seconds. The application-specific receive signals are analyzed by the
sensor during this time, on the basis of which the switching threshold is calculated. And thus application-spe-
cific receive signals do not result in erroneous sensors switching.
• Install the sensor in accordance with the mounting instructions.
• Align the sensor to the reflector.
• Press and hold the teach-in key until switching status indicator A1 starts blinking rapidly (4 Hz) after five
seconds.
• Release the teach-in key.
• Recording is started during which the LED continues to blink at a rate of 4 Hz.
• The sensor analyzes the receive signals for 10 seconds, on the basis of which it calculates a precise
switching threshold that’s matched to the application.
• The calculated switching threshold is taught in and the LED for A1 blinks twice in order to confirm suc-
cessful teach-in. If teach-in has not been successful, LED A1 blinks 4 times. If this is the case, the proce-
dure must be repeated.
NOTE!
If the sensor is used at a very small distance above a conveyor belt, it’s advisable to acti-
vate the belt during the recording phase. Height fluctuations, impacts, belt seams etc. are
analyzed as a result and made use of when calculating the switching threshold. Erroneous
switching due to the conveyor belt can be avoided in this way.
7. Maintenance Instructions
NOTE!
• This wenglor sensor is maintenance-free.
• Cleaning and inspection of the plug connections at regular intervals are advisable.
• Do not clean the sensor with solvents or cleansers which could damage the product.
• The product must be protected against contamination during initial start-up.
8. Proper Disposal
