Tx/Rx power
The structure of the configuration in the receiver control panel menu is as follows:
Select Main Settings > Sensitivity Setting > Function Reserve > Tx/Rx Power
For the receiving sensitivity (Rx), enter a value between 1 (lowest sensitivity) and 22 (highest sensi
-
tivity).
• Select maximum sensitivity for high beam penetration capacity.
At maximum sensitivity, the light curtain may still be able to detect objects if a transparent medium
allows almost no energy to pass through.
• If the receiver is set to an extremely high sensitivity, the light curtain switches even with extremely
small objects which cause only very slight damping. In this case, the light curtain becomes e.g. more
sensitive to dust if a low function reserve is set.
• Higher sensitivity of the receiver also means higher measurement value noise. The measurement
value noise alone may cause pseudo switching of the light curtain if the hysteresis is set too low.
For the transmitting power (Tx), enter a value between 3% (lowest transmitting power) and 100% (high
-
est transmitting power).
For the switching threshold, enter a value between 10% (lowest sensitivity) and 98% (highest sensi
-
tivity). Factory setting: 75%
For the hysteresis, enter a value for the reactivation threshold after switching (5% … 80%). This
smooths any bounce around a limit value.
Example: Switching threshold: 75%; hysteresis: 10%. The light curtain switches off when 65% of the
light quantity configured using the transmitting power reaches the receiver. The light curtain switches
on again when 75% of the light quantity configured using the transmitting power reaches the receiver.
NOTICE
Switching the function reserve!
If the function reserve is switched to
High

Medium
,
Low
or
Transparent
, the switching threshold and
hysteresis are reset to a specific factory setting.

NOTICE
Determine and note down the Tx/Rx setting!
Determine by trial and error the
Tx/Rx power
settings with which the desired switching behavior is best
reached in your application.
Note down your
Tx/Rx power
settings so that you can restore the settings if necessary.
