REMOTE FUNCTION AND PUSH-BUTTON BLOCKING
Using the REMOTE input, it is possible to perform the same SET check outside the sensor.
When the REMOTE wire is connected to +Vdc, it is as if the SET push-button was pressed.
Upon sensor switch-on, if the REMOTE wire is connected to +VDC, the block function is activated so
the SET push-button is no longer active.
To disable push-button block, switch sensor off and back on with the REMOTE wire disconnected or
connected to 0 V.
After push-button block, it is possible to program the device using the REMOTE input.
EARTH CONNECTION
You can connect to the earth in the following ways:
1. SR23 M8 conn. & Cable: by the M5 threaded hole on the body (preferential).
2. SR23 M8 conn.: by the use of a shielded cable with the shield connected to earth; use a shielded
cable with the shield connected to the threaded nut on the cable.
3. SR23 cable: by the connection of the cable shield itself.

The device is factory-set with output active on support-label (background).
This setting can be changed as described below.
DYNAMIC acquisition:
A) Insert labels into sensor slot.
B) Press SET push-button for 1 second until the READY green LED switches OFF.
If the OUT yellow LED is ON, it will turn off together with the READY green LED.
C) Release SET push-button.
At this stage, switching output is frozen on the last valid status before acquisition.
D) The READY green LED blinks slowly, thereby indicating acquisition in progress.
E) Slide the labels through the sensor, at a maximum speed of 20 m/min (30 cm/s), until at least 3...8
labels get through the sensor.
F) Briefly press SET push-button to end acquisition stage: 3 blinks of the READY green LED indicate
correct acquisition.
10 ... 30 VDC;
In case of unsuccessful acquisition, the READY green LED blinks quickly.
If this is the case, briefly press SET push-button to go back to the beginning of acquisition stage and

repeat the process.
If error persists, label-to-background contrast might be not sufficient to obtain a correct acquisition

result.
STATIC acquisition:
10... 30 VDC
A) Place the object to detect (the support or the label) into the sensor slot.
100 mA max.
If necessary, remove one or more labels to help positioning on the support.
B) Press SET push-button for 3 seconds until the OUT yellow LED blinks.
≤ 0.2µF
When you press SET, if the OUT yellow LED is on, it will turn off in 1 second.
2 V max.
At this stage, switching output is frozen on the last valid status before acquisition.
C) Release SET push-button; the sensor acquires the target.
40 µs max.
The OUT yellow LED blinks slowly.
12 kHz max.
D) Place the object to ignore (the support or the label) into the sensor slot.
E) Briefly press SET push-button; the sensor acquires the target: 3 blinks of the READY green LED
indicate correct acquisition.
SET push-button
In case of unsuccessful acquisition, the READY green LED blinks quickly.
If this is the case, briefly press SET push-button to go back to the beginning of acquisition stage and
-20 ... 55°C
repeat the process.
-20 ... 70°C If error persists, label-to-background contrast might be not sufficient to obtain a correct acquisition
result.
Reversing Output status:
A) Press SET push-button for 7 seconds until both READY green LED and OUT yellow LED blink at
the same time.
at least 12.7 mm
B) Release SET push-button.
Output status is now reversed compared to previous conditions.
This setting is saved to the device.
Restoring the device factory settings:
A) Press SET push-button for 12 seconds until both READY green LED and OUT yellow LED blink
quickly.
5 mm
B) Release SET push-button.
50 mm
The device factory settings are now restored.
Output short-circuit warning:
Zinc alloy In case of short-circuit of the PNP or NPN output, the READY green LED and OUT yellow LED blink
