microsonic zws-15 Ultrasonic Proximity Switch with One Switching Output
Product Information
The Zws sensor is an ultrasonic proximity switch with one switching output. It is available in different models – zws-15/CD/QS, zws-24/CD/QS, zws-25/CD/QS, zws-35/CD/QS, andzws-70/CD/QS; and zws-15/CE/QS, zws-24/CE/QS, zws-25/CE/QS, zws-35/CE/QS, and zws-70/CE/QS. The sensor offers a non-contact measurement of the distance to an object which must be positioned within the sensor’s detection zone. The switching output is set in dependence of the adjusted detect distance. Via the push-button, the detect distance and operating mode can be adjusted (Teach-in). Two LEDs indicate the operation and the state of the switching output.
Product Usage Instructions
-
Read the operation manual prior to start-up.
-
Connection, installation, and adjustment works may only be carried out by expert personnel.
-
Use the sensor only for its intended purpose – non-contact detection of objects.
-
Set sensor parameters via the Teach-in procedure as per Diagram 1.
-
Factory settings:
- Operation with one switching point
- Switching output on NOC
- Switching point at an operating range
-
Three operating modes are available for the switching output:
-
Operation with one switching point – The switching output is
set if the object falls below the set switching point. -
Window mode – The switching output is set if the object is
within the set window limits. -
Two-way reflective barrier – The switching output is set if
there is no object between the sensor and the reflector.
-
-
Further settings:
- Set switching outputs
- Set window mode
- Set a two-way reflective barrier
- Set NOC/NCC and twin mode 1)
- Enable/disable the Teach-in push-button
- Reset to factory setting
- Switch off
-
To update firmware, press the push-button for about 3 s until LEDs flash simultaneously.
-
To change the output characteristic, press the push-button for about 1 s.
-
To switch on, press and hold the push-button, then switch on the operating voltage. Keep the push-button pressed for about 3 s until both LEDs flash simultaneously.
Product Description
The zws sensor offers a non-contact measurement of the distance to an object which must be positioned within the sensor’s detection zone. The switching output is set in dependence of the adjusted detect distance. Via the push- button, the detect distance and operating mode can be adjusted (Teach-in). Two LEDs indicate operation and the state of the switching output.
Safety Notes
- Read the operation manual prior to start-up.
- Connection, installation and adjustment works may only be carried out by expert personnel.
- No safety component in accordance with the EU Machine Directive, use in the area of personal and machine protection not permitted.
Use for intended purpose only
zws ultrasonic sensors are used for non-contact detection of objects.
Installation
-
Mount the sensor at the installation site with the aid of the enclosed mounting plate (see Fig. 1).
Maximum torque of attachment screw: 0,5 N
-
Connect a connection cable to the M8 device plug.
-
Avoid mechanical load on the connector. Start-Up
-
Connect the power supply.
-
Carry out the adjustment in accordance with Diagram 1.
Factory Setting
zws sensors are delivered with the following settings:
- Operation with one switching point
- Switching output on NOC
- Switching point at an operating range
Operating modes
Three operating modes are available for the switching output:
- Operation with one switching point
- The switching output is set if the object falls below the set switching point.
Window mode
- The switching output is set if the object is within the set window limits.
Two-way reflective barrier
The switching output is set if there is no object between the sensor and the
reflector.
Checking operating mode
In normal operating mode shortly press the push button.
The green LED stops shining for one second, then it will show the current operating mode:
- 1x flashing = operation with one switching point
- 2x flashing = window mode
- 3x flashing = reflective barrier
After a break of 3 s the green LED shows the output function:
- 1x flashing = NOC
- 2x flashing = NCC
- 3x flashing = NOC (twin)
- 4x flashing = NCC (twin)
Mutual Influencing and Synchronization
If two or more sensors are mounted too close to one another and the minimum assembly distances (see Fig. 3) between the sensors are not reached they can influence one another. There are two methods available to avoid this.
-
If only two sensors are operating, the twin mode can be selected at one of the two sensors via the sensor setting »Set NOC/NCC and twin mode«. The other sensor stays at
the standard NOC/NCC setting. For the sensor in twin mode, the response delay is slightly increased und therefore the switching frequency is reduced. -
If more than two sensors are operating close to one another, the sensors can be synchronized by the accessory SyncBox2.
Maintenance
microsonic sensors are maintenance-free.
In case of excess caked-on dirt we recommend cleaning the white sensor
surface.
Technical Data
Notes
- The zws sensor has a blind zone, within which distance measurements are not possible.
- The sensor has no temperature compensation.
- In the normal operating mode, an illuminated yellow LED signals the switching output is switched through.
- In the »Set switching point – method A« Teach-in procedure the actual distance to the object is taught to the sensor as the switching point. If the object moves towards the sensor (e.g. with level control) then the taught distance is the level at which the sensor has to switch the output.
- If the object to be scanned moves into the detection area from the side, the »Set switching point +8 % –method B« Teach-in procedureshould be used. In this way the switching distance is set 8 % furtherthan the actual measured distanceto the object. This ensures a reliable switching distance even if theheight of the objects varies slightly,see Fig. 4.
- In the »Two-way reflective barrier« operating mode, the object has to be within the range of 0 to 85 % of the set distance.
- If the push-button is not pressed for 8 minutes during the Teach-in setting, the settings made until now are deleted.
- This operation manual applies to zws sensors from firmware version V3. The firmware version can be checked via Teach-in procedure »Set NOC/NCC and twin mode«. If the yellow LED flashes, this zws sensor has firmware V3 or higher.
