7.4.2 Q1 and Q2 / Qa settings
7.4.2.1 Switching point logic
The switching point logic describes the relationship between the output state (active or
inactive) and the potential applied to the digital output (high or low).
Settings (depending on output mode)
•
High-active : The digital output acts as a normally open contact. If the switching
point that has been taught in is undershot, a signal is output.
•
Low-active : The digital output acts as a normally closed contact. If the switching
point that has been taught in is exceeded, a signal is output.

7.4.2.2 Timer mode
Timer mode is used to issue output state changes with a time delay or as a short
switching pulse (
Pulse (one shot) ). The delay time is adjustable.

2
Off : Right after the measured distance has exceeded the specified switching point, the
state of the digital output changes (factory setting).
3
Switch-on delay : The changeover of the digital output from an inactive to an active state is
time-delayed. The changeover from an active to an inactive state is not delayed.
4
Switch-off delay : The changeover of the digital output from an active to an inactive state is
time-delayed. The changeover from an inactive to an active state is not delayed.
5
Switch-on/off delay : Both transitions are time-delayed.
6
Pulse (one shot) : Once the switching condition has been met, the digital output changes
from an inactive to an active state. The output state remains in an active state for a
specified period regardless of how long the switching condition is met. It does not switch
back to an inactive state until this time has elapsed. Any additional changes made to the
switching condition during this period are still not taken into account.
