microsonic IO-Link Ultrasonic Proximity Switch

Product Information

The Ultrasonic Proximity Switch is a sensor that detects objects without any physical contact. The product has one analogue output,one switching output, and IO-Link capability. The lpc+ sensor is IO-Link-capable in accordance with IO-Link specification V1.1 and supports Smart Sensor Profile like Digital Measuring Sensor. The product can be monitored and parameterized via IO-Link.

product Safety Instructions

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

product Proper Use

The Ultrasonic Proximity Switch is used for the non-contact detection of objects.

Pin Assignment and Connection
The Ultrasonic Proximity Switch comes with an M12 device plug. The pin assignment with view of sensor plug, IO-Link notation, and color coding of the microsonic connection cables can be seen in Fig. 1.

product Operating Modes

Three operating modes are available for the switching output:

• Operation with one switching point: The switching output is set when the object falls below the set switching point.
• Window mode: The switching output is set when the object is outside the window limits.
• Two-way reflective barrier: The switching output is set when the object is between sensor and fixed reflector.

Teach-in Procedure
The Teach-in procedure is used to set sensor parameters. The steps for each operating mode are as follows:

Switching Point Operation

1. Place object at position 1.
2. Connect Com for about 3 s to +UB, until both LEDs flash simultaneously. Both LEDs: flash alternately.
3. Place object at position 2. Both LEDs: flash alternately.
4. Connect Com for about 1 s to +UB.

Window Mode

1. Place object at position 1.
2. Set window mode to 92%.
3. Place object at position 2.
4. Connect Com for about 3 s to +UB, until both LEDs flash alternately.
5. Connect Com for about 1 s to +UB.

Two-way Reflective Barrier

1. Place the object at position 1.
2. Place the reflector at position 1.
3. Connect Com for about 3 s to +UB, until both LEDs flash alternately.
4. Connect Com for about 10 s to +UB, until both LEDs stop flashing.

Output Characteristics
The Ultrasonic Proximity Switch has a rising analogue characteristic and window limits for the analog output. To change the output characteristic, connect Com for about 1 s to +UB and wait for 10 s.

Product Description

The lpc+ 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 conditional upon the adjusted switching distance. A distance- proportional analogue signalis output depending on the set window limits. Via the Teach-in procedure, the detect distance and operating mode can be adjusted. The states of the switching and analogue output are each indicated by two LEDs (green/yellow).

IO-Link
The lpc+ sensor is IO-Link-capable in accordance with IO-Link specification V1.1 and supports Smart Sensor Profile like Digital Measuring Sensor. The sensor can be monitored and parameterized via IO-Link.

Safety instructions

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

Proper Use

lpc+ 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, see Fig. 1.
• Fig. 1: Pin assignment with view onto sensor plug, IO-Link notation and colour coding of the microsonic connection cables

Start-up

• Connect the power supply.
• Set the parameters of the sensor by using the Teach-in procedure, see Diagram 1.

Factory Settings

• Switching point operation
• Switching output on NOC
• Switching distance at operating range
• Rising analogue characteristic
• Window limits for the analogue output at maximum value of the blind zone and the operating range
• Input Com set to »Teach-in + Sync«
• Filter at F01
• Filter strength at P00

Operating modes

Three operating modes are available for the switching output:

• Operation with one switching point
  The switching output is set when the object falls below the set switching point.

• Window mode
  The switching output is set when the object is outside the window limits.

• Two-way reflective barrier
  The switching output is set when the object is between sensor and fixed reflector.

Technical Data

Synchronization
If the assembly distance of multiple sensors falls below the values shown in Fig. 2, internal synchronization should be used (»Teach-in + sync« must be switched on, see Diagram 1). For this purpose set the switching and analogue outputs of all sensors in ac-cordance with Diagram 1. Finally interconnect each pin 5 of the sensors to be synchronized.

Maintenance

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

Notes

• Pin 5 (Com) of the sensor may only be connected during Teach-in procedures or for synchronization.
• The sensors of the lpc+ family have a blind zone, within which a distance measurement is not possible.
• The lpc+ sensors are equipped with an internal temperature compensation. Due to the sensor’s self-heating, the temperature compensation reaches its optimal working point after approx. 120 seconds of operation.
• In the normal operating mode, an illuminated yellow LED D2 signals that the related switching output is set.
• In the normal operating mode, an illuminated yellow LED D1 signals that the object is within the analog window limits.
• In IO-Link mode, the green LED D2 flashes.
• In the »Two-way reflective barrier« operating mode, the object has to be within the range of 0 to 92 % of the set distance.
• In the »Set switching point – method A« Teach-in procedure the actual distance to the object is taught to the sensor as the detect 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, see Fig. 3.
• If the object to be scanned moves into the detection area from the side, the »Set switching point +8 % – method B« Teach-in procedure should be used. In this way the switching distance is set 8 % further than the actual measured distance to the object. This ensures a reliable switching behavior even if the height of the objects varies slightly, see Fig. 3.
• The sensor can be reset to its factory setting (see »Further settings«).
• The lpc+ sensor can be blocked against changes in the sensor via function »Switch on or off Teach-in + sync«, see Diagram 1.
• Using the LinkControl adapter LCA-2 (optional accessory) and the LinkControl software for Windows®, all Teach-in and additional sensor parameter can be optionally adjusted.
