Operation ILR2250-100

optoNCDT ILR2250

6.5

Triggering

6.5.1

General

The acquisition and output of measured values by the ILR2250 can be controlled using an external electrical trigger sig-
nal or commands. Digital outputs are affected by this. The measured value at the time of the trigger event is output with a
delay,

-

Triggering has no effect on the preselected measuring rate or on the time response, and therefore there are always 4
1 cycle (jitter) between the trigger event (level change) and the start of the output.

-

The

TRIG

input is used as the external trigger input.

-

Factory setting: no triggering, the sensor starts with the measured value output immediately after being switched on.

-

The pulse duration of the “Trigger in” signal is at least 2 ms.

The triggering of the measured value acquisition and output have the same time response.

Switch to the

Settings

>

Trigger

menu and select the desired triggering conditions.

Mode

Pulse / Edge / Software / None

Selection for the desired type of triggering.
Pulse = level triggering, Edge = edge triggering or pure Software
triggering
None: no triggering, continuous measured value output

Level

High / Low

With edge triggering and High: rising edge
With edge triggering and Low: falling edge

Input / Output

Defines type of triggering
Input = data acquisition, output = data output

Number

Value

For edge and software triggering, the number of measured values to
be output must be specified.

The following applies for triggering:

The following are used as triggering conditions:

Level triggering

with high level / low level.

Continuous measured value acquisition/output as long as the
selected level is present. Afterwards, the data acquisition/out-
put stops.
The pulse duration must be at least as long as one cycle.
The subsequent pause must also be at least as long as one
cycle.
