Product Information

Analogue Output
The Nero sensor is a non-contact measurement device used to detect the distance of an object within its detection zone. The device comes in various models, including nero-15/CI, nero-25/CI, nero-35/CI, nero-100/CI, nero-15/WK/CI, nero-25/WK/CI, nero-35/WK/CI, and nero-100/WK/CI. It also includes models with a CU suffix, which indicates a different housing material. The device has one analogue output that produces a distance- proportional signal that can be adjusted using the Teach-in procedure. The device includes two LEDs that indicate operation and the state of the analogue output.

Safety Instructions
Before starting up the device, read the operating manual carefully. Only qualified personnel should carry out connection, installation, and adjustments. The device is not a safety component and should not be used for personal and machine protection. Use the device only for its intended purpose.

Product Usage Instructions

To use the Nero sensor:

1. Connect the M12 device plug according to the pin assignment shown in Fig. 1.
2. Ensure that the minimum assembly distances shown in Fig. 2 are not fallen below when using two or more sensors to avoid mutual interference.
3. Use the Teach-in procedure to adjust the window limits and characteristic curve of the analogue output. Refer to Diagram 1 for instructions on setting sensor parameters via Teach-in.
4. In normal operating mode, an illuminated yellow LED signals that an object is within the adjusted window limits.
5. Note that the device has a blind zone within which distance measurement is not possible.
6. If excess caked-on dirt accumulates on the white sensor surface, clean it as recommended.

Product Description

The Nero sensor offers a non-contact measurement of the distance to an object that has to be positioned within the sensor’s detection zone. Depending on the settings window limits, a dis-tance-proportional analogue signal is an output.

The window limits of the analogue output and its characteristic can be adjusted with the Teach-in procedure. Two LEDs indicate the operation and the state of the analogue output.

Safety instructions

• Read the operating manual prior to start-up.
• Connection, installation, and ad- adjustments may only be carried out by qualified staff.
• No safety component in accordance with the EU Machine Directive, use in the area of per-sonal and machine protection not permitted.

Use for intended purpose only
Nero ultrasonic sensors are used for non-contact detection of objects.

Installation

• Mount the sensor at the place of the fitting.
• Connect a connection cable to the M12 device plug, see Fig. 1.

The assembly distances shown in Fig. 2 for two or more sensors should not be fallen below in order to avoid mutual interference.

Start-up

• Connect the power supply.
• Carry out sensor adjustment in accordance with Diagram 1.

Factory setting

Nero sensors are delivered factory-made with the following settings:

• The rising analogue characteristic curve between the blind zone and the operating range
• »Teach-in« active

Maintenance

microscopic sensors are maintenance-free. In case of excess caked-on dirt, we recommend cleaning the white sensor surface.

Notes

• The sensors of the Nero family have a blind zone, within which a dis-tance measurement is not possible.
• In normal operating mode, an illuminated yellow LED signals the object is within the adjusted win-dow limits.
• The sensor can be reset to its factory setting (see »Further settings«, Diagram 1).
