Product Usage Instructions

Safety Notes Before using the WMS ultrasonic sensor, please read the operating manual thoroughly. Only qualified personnel should handle connection, installation, and adjustments. The sensor is not a safety component as per the EU Machine Directive and should not be used for personal or machine protection.

Proper Use The WMS ultrasonic sensors are designed for non-contact detection of objects. Follow the control and signal evaluation equipment setup as shown in Fig. 1 below.

Connection and Installation Connect the sensor plug according to the pin assignment and color code provided in Fig. 1. Ensure proper alignment and secure connections.

Operating Range Adjustment The operating range varies based on the model. Consider factors like reflectors and object material that may affect the sensor’s performance. Refer to the technical data for specific operating ranges.

Maintenance Regularly inspect the sensor for any damages or dirt that may affect its performance. Clean the sensor gently with a soft cloth if needed.

Product Description

The WMS sensors require a connection to the customer´s control and signal evaluation equipment.

Safety Notes

• Read the operating manual before starting.
• Connection, installation, and adjustments may only be carried out by qualified staff.
• No safety component per the EU Machine Directive, use in the area of personal and machine protection is not permitted.

The wms sensors indicate a blind zone, in which the distance cannot be measured. The operating range indicates the distance of the sensor that can be applied with normal reflectors with sufficient function reserve. When using good reflectors, such as a calm water surface, the sensor can also be used up to its maximum range. Objects that strongly absorb (e.g. plastic foam) or diffusely reflect sound (e.g. pebble stones) can also reduce the defined operating range.

Proper Use

wms ultrasonic sensors are used for non-contact detection of objects.

Installation

• Mount the sensor at the place of fitting.
• Connect a connection cable to the M12 device plug.
• Connect the sensor to your own control and signal evaluation equipment according to Fig. 1.

Signal input »Transmitter«

A signal on the input makes the WMS sensor emit a sound pulse. For this, an open collector output has to earth the »transmitter« signal input for the time given in the technical data table below.

Signal output »Echo«

The signal output »Echo«subsequently transmits all echo signals received depending on the duration as 1-bit values (echo yes/no).

Frequently Asked Questions (FAQ)

Q: Can the WMS ultrasonic sensor be used for personal safety?
A: No, the sensor is not designed for personal or machine protection according to the EU Machine Directive.

Q: What should I do if the sensor indicates a blind zone?
A: If a blind zone is indicated, consider adjusting the position or angle of the sensor for better detection.

Q: How often should I calibrate the sensor?
A: Calibration frequency may vary based on usage and environmental conditions. It is recommended to calibrate the sensor periodically to ensure accurate readings.
