21 Reflex Sensor with Analog Output
8. External Teach-In
Before a external Teach-In process the desired Teach-In Mode has to be set at the Sensor one time in
advance (view Chapter 7.5).
8.1 External Foreground Teach-In
Align the Sensor to the object.
Connect the Teach input to 18…30 V DC for approx. 5 sec. until PLU flashes. In the next step, disconnect the
voltage supply from the Teach input until SPU flashes.
Connect the Teach-In Input approx. 1sec. to 18…30 V DC.
The display doesn't change from Distance Value to SP U any more.

Point is teached.
8.2 External Window Teach-In
Align the Sensor to the object.
Position the object at the front point (SP 1) of the Teach-In Window.
Connect the Teach input to 18…30 V DC for approx. 5 sec. until PLF flashes. In the next step, disconnect the
voltage supply from the Teach input until SP1 flashes.
The display does no longer change between distance value and SP 1.
Connect the Teach input to 18…30 V DC for approx. 1 sec.

Point (SP 1) is teached

SP 2 blinks
Position the object at the rear point (SP 2) of the Teach-In Window.
Connect the Teach-In Input for approx. 1 sec. to 18…30 V DC.
The display doesn't change from Distance Value to SP 2 any more.

Point is teached. (SP 2)
9. Locking
If the Teach-In Input is permanentely connected to 18...30 V DC, the sensor is locked and protected against
unintended adjustments. The sensor must be switched off when voltage is applied to the teach-in input.
Otherwise sensor locking is not activated.
