Reflex Sensor with Analog Output
1. Proper Use
This wenglor product has to be used according to the following functional principle:
Ultrasonic reflex sensors with analog output can be adjusted using Teach-In, or externally via the IO-Link
interface. Sensors of the type M30×1.5 also feature a four digit 7-segment display.
If several UMF reflex sensors are in operation in the immediate vicinity, you can choose between synchronous
and multiplex mode. In synchronous mode, all synchronized sensors send out ultrasound pulses
simultaneously. As a result, object detection is possible over a wider area.
In multiplex mode, the sensors send their ultrasonic pulses alternately, so that sensors which are mounted
side by side do not interact with each other.
2. Safety Precautions
• This operating instruction is part of the product and must be kept during its entire service life.
• Read this operating instruction carefully before using the product.
• Installation, start-up and maintenance of this product has only to be carried out by trained personnel.
• Tampering with or modifying the product is not permissible.
• Protect the product against contamination during start-up.
• Not a safety component in accordance with the EU Machinery Directive.

The warm-up phase takes approx. 30 minutes. At the beginning of this time, the linearity deviation and the
reproducibility may deviate. During the warm-up phase, the values improve in the form of an exponential
function until the technical data are achieved. The sensor works with an internal temperature compensation
in order to compensate air temperature fluctuations. Via the IO link interface, you can also specify externally
determined temperature values.

10 Mounting instructions
5. Mounting instructions
During mounting and operation of the sensors, the corresponding electrical and mechanical regulations, as
well as safety regulations must be observed. The sensor must be protected from mechanical impact. The
product has to be mounted so that the mounting position can not be changed.
• Make sure that the sensor is mounted in a mechanically secure fashion.
• If the object has smooth surfaces, the angle between the axis of the sound waves and the surface of the
object should be 90° ±3°. The angle can be considerably larger in the case of rough object surfaces.
• The active surface of the sensor may not contact any other machine parts.
NOTE!
Observe the blind spot.
In the area between the sensor’s active surface and the beginning of its working range, cor-
rect functioning of the sensor is not assured. No objects may be located in this area.

Reflex Sensor with Analog Output
5.1 Causes for Triggering Error Indication (LED Plus Button)
• Too little ultrasonic is reflected.
• Very small objects, or objects which do not reflect sound well (sound-absorbing objects), are located
within the working range.
• Incorrect installation
• Object outside of the working range
• Strong sources of ultrasound within the axis of the sound waves
• Strong air turbulence
6. Initial Operation
An IO-Link master with port Class A must be used, as for port Class A pin 5 is not connected.
Connect the sensor to 18…30 V DC.
In order to enter the configuration menu press the Mode key for 5 seconds. By pressing the Mode key again
you change between the submenus.
The display shows the submenu and which setting is activated.
Example:
SL: Submenu: Change Switching Logic
no: Setting: NO
By pressing the Plus key the setting in the respective submenu is changed.
In order to leave the configuration menu, you have to change to the “Display mode (run)” submenu. By
pressing the plus key, you leave the configuration menu. You can directly jump to the display mode from
every submenu by pressing the Mode key for approx. 5 seconds.
Important: In order to prevent a demage of the keys please don't use sharp objects for setting.

7.11 FL (Set Filter)
Depending upon the filter level 0…7 several additional ultrasonic impulses are taken
for measurement. In this way, interference signals can be suppressed. The larger the
selected filter the slower the response time of the sensor in case the measured values
are changed.
NOTE!
The switching frequency reduces the higher the filter is set.

Several sensors send ultrasonic impulses
simultaneously (synchron).
Several sensors send ultrasonic impulses
alternately (cyclic).
In both operating modes the Sensors are connected to each other through pin 5 (T/SY).
Please note: Synchronous and multiplex operation are only possible with sensors of the same type.
Setting Description
0 Normal
The Sensor is in normal mode.
1 Synchron Slave
The Sensor is in synchronous slave mode. It gets simultaneously an impulse
from the Master via Pin 5 to send out an Ultrasonic impulse for capturing a big-
ger detection zone with several sensors.
2 Synchron Master
The Sensor is in synchronous master mode. It sends out impulses automati-
cally to the connected Slaves via Pin 5 (T/SY), in order that they all send out
Ultrasonic impulses (synchronously).
3 Synchron Receiver
The Sensor is in synchronous receiver mode. Via pin 5, the slave receives the
information from the master when the latter transmits ultrasonic signals. The
sensor can only receive ultrasonic impulses does, however, not transmit them.
This can be used to detect objects deflecting the sound of the transmitter so
that the latter can no longer receive reflected sound waves. One or several sen-
sors positioned as synchronous receivers allow for the reception of such sound
waves. Operation as one-way light barrier is possible as well. However here,
the synchronous receiver only displays half the measured value.

19
Reflex Sensor with Analog Output
4 Multiplex Slave
The Sensor is in multiplex slave mode. Via pin 5, the master transmits tempo-
rarily delayed signals to the slaves so that they transmit consecutively clocked
ultrasonic impulses.
5 Multiplex Master
The Sensor is in multiplex master mode. It sends out impulses automatically to
the connected Slaves via Pin 5 (T/SY), in order that they all send out Ultrasonic
impulses one after another.
6 Mute
The Ultrasonic Emitter of the Sensor is switched off. Signals from other sensors
are not accepted either.
7.13 Ad*¹ (Set Multiplex Participants Address)
For each Multiplex Slave Sensor a participants address between 0 and 15 has to be
selected. In this order the Multiplex Slaves are then supplied with impulses by the
Multiplex Master.
*¹ NOTE!
Only possible if the Operating Mode is set to „Multiplex Slave“. View Chapter 7.12
7.14 nr*² (Set Number of Multiplex Participants)
The number of the Slave Sensors that are connected to a Master has to be entered
