8-2-2-3-1 Pin assignments
The functions of Connector pin 2 and Connector pin 5 are set in the Pin
Assignment box.
In total, the sensor can be operated with a maximum of three inputs/outputs,
and a maximum of two outputs is possible at the same time.
The functions of the inputs/outputs can be set in the following order:
Connector pin 4 is always defined as Output 1 (OUT1) and cannot be modi-
fied.
Connector pin 2 can be set as Switching output 2 (OUT2), teaching input
(TEACH) for the switching points A and C or as the test input (TEST) or trig-
ger input (TRIG) .
Connector pin 5 can be set as the trigger input (TRIG) , teaching input
(TEACH) for the switching points A to D or as the test input (TEST ).
• Teaching input TEACH
If a signal in the operating voltage range (at least 10 V) is applied to this
input, the switching point A, B, C or D is teached, depending on the set-
tings, and analogously to the Teach buttons
(see Section 8-2-1-1 Teaching
switching points)
.
• Test input TEST
The emitter is deactivated if a signal in the operating voltage range (at
least 10 V) is applied to this input.
If the sensor is in the light-on state, the receiver detects the absence of
the emitted light reflected by the measured object, regardless of the set-
ted switching points.
The output state changes.
This function can be used to test correct functioning of the sensor.
• Trigger input TRIG
If a signal in the operating voltage range is applied to this input, the sen-
sor is requested to start a measurement (object distance).
The sensor rate (response time) can be increased by the trigger func-
tion.
• Switching outputs OUT1 and OUT2
The switching outputs switch when a measured object is detected and in
accordance with the sensor's settings.
