Description of Sensor Parameters
8.2.9
Switch-Off Delay
You can use the "Switch-off delay" parameter to delay the switching output being switched off.
This delay can be helpful if very fast events need to be reliably reported by programmable logic
controllers with slower cycle time. A switch-off delay can also be useful when needing to
ensure a certain over-travel time for components in applications.
The "output logic" parameter determines which signal change is considered as a "switch-off
process."
If the output logic is set to "normally-open," the switch-off delay effects the change of output
state from "Closed" to "Open."
If the output logic is set to "normally-closed," the switch-off delay effects the change of output
state from "Open" to "Closed."

Analog Output
8.3.1
Output Mode
Depending on the intended purpose of the sensor and its associated task, you can use this
parameter to adapt the mode to the analog output. With "Rising ramp," the analog output value
increases with an increasing object distance; with "Falling ramp," the analog output value
reduces with an increasing object distance.
In practice, the "Falling ramp" output mode is usually used to display fill levels in a tank because
a large analog value also corresponds to a large quantity of liquid in the tank.
For other applications in which the distance to the sensor is relevant, the "Rising ramp" output
mode is usually used because a larger analog value also corresponds to a greater distance
from the sensor.
8.3.2
Output Type
You can physically operate the analog output of the sensor either as current or voltage output
and select this via this parameter.
Note!
This parameter influences the response time of the sensor.
