8.2.6
Switching Hysteresis
You can use this parameter to set the hysteresis for switch points 1 and 2. You can choose
between three settings (low, medium, high). "Low" corresponds to a hysteresis of 1 % of the
measured distance value, "medium" to 2 % and "high" to 5 %. In any case, the hysteresis is
always at least 1 mm in size.
8.2.7
Switch-On Delay
You can use the "Switch-on delay" parameter to delay the switching output being switched on
in order to stabilize the output signal and suppress short switching pulses resulting from poten-
tial interference.
The "output logic" parameter determines which signal change is considered as a "switch-on
process."
If the output logic is set to "normally-open," the switch-on delay effects the change of output
state from "Open" to "Closed."
If the output logic is set to "normally-closed," the switch-on delay effects the change of output
state from "Closed" to "Open."
Note
An offset value of at least 10 % of the reflector distance is typically recommended to prevent
impact of temperature fluctuations, in outdoor applications too.
Note
The "Switching hysteresis" parameter is not relevant if output mode is set to "Hysteresis mode"
and is hidden in the DTM.
