6.4.2.5
“Off” output function
The “Off” output function is only accessible if the “Advanced” user level is activated.
In the “Off” output function, output 2 does not have any function and is therefore
deactivated.
6.4.3
Switching mode for Q
2
(“ModeQ
2
”)
If the output function for Q
2
(“Function Q
2
/Q
a
”) is set to “Switching”, the following
switching modes are available:
■
Distance to object or single switching point (“DtO (1point)”)
■
Switching window (“Window”)
■
Object between sensor and background (“ObSB (Background)”)
■
Shape comparison (“Shape”, Advanced user level only)
■
Fault output (“Alarm”, Advanced user level only)
■
Signal level warning (“SLWarning”, Advanced user level only)
Since this and its function, apart from the designation (Q
2
instead of Q
1
) are absolutely
identical to the switching modes for Q
1
, the following chapters do not provide a new
description. For more details about the switching modes and operating examples for
output Q
2
, refer to the
chapter.
6.4.4
Analog mode for Q
a
(„ModeQ
a
“)
In the factory settings of DT50-2 Pro, output 2 is operated in the “Distance” analog
mode. If the “4-20 mA” or “0-10 V” output function has been selected and the
Advanced user level has been activated, you can choose between “Distance” (
"“Distance” analog mode", page 49
see "“Shape comparison” (“Shape”)
) for the analog mode or the measured value to be output.
6.4.4.1
“Distance” analog mode
6.4.4.1.1
Description
In the “Distance” analog mode, the measured distance value is output as a linearly
proportional current or voltage signal, according to the selected setting for the output
function. Depending on the setting, the analog output behavior for this can be “rising”
or “falling”.
