Teaching the environmental conditions

During teaching, the system checks whether the signals of all beams are within a certain corridor.
This means that a teach event generally regulates all beams to the preset function reserve (or sensitivity)
for the current operating range. This ensures that all beams exhibit an identical switching behavior.
NOTICE
Conditions for performing a teach!
 When teaching without preconfigured blanking areas, the light path must always be completely free.
A teaching error will otherwise occur.
 In this case, remove the obstacles and repeat the teach.
 If the light path is partially interrupted by structural elements, the permanently interrupted beams can
be suppressed by means of blanking (
this case.
 To automatically suppress the affected beams during teaching, configure the number of blanking
areas via the configuration software
The configuration can be performed via the respective fieldbus interface (see chapter 9 et seq.)
or via the
You can choose whether the teach values are to be stored permanently or only temporarily (while
the operating voltage is applied). The configuration ex works is for permanent (non-volatile) stor-
age.
A teach event can be performed both directly from process mode as well as from alignment
mode.
NOTICE
Execute teach after changing the beam mode!
 Always perform a teach after changing the beam mode (parallel-/diagonal-/crossed-beam scanning)
as well.
Prerequisites:
• The light curtain must be correctly aligned (see chapter 8.1).
• The bar graph indicator must show a minimum level.
 You can use one of the following teach types:
Teach via receiver control panel (see chapter 8.2.1).
Teach via teach input (see chapter 8.2.2).
Teach via fieldbus interface (IO-Link, see chapter 9; CANopen, see chapter 10).
