2 Product Description
2.1 Use and Application
The UC***-18GS series ultrasonic sensors use ultrasonic pulses to detect objects. The sensor
emits ultrasound, which is reflected by the object and received again by the sensor. The mea-
sured sound propagation time is used to determine the distance to the object (pulse-echo prin-
ciple). Objects in the following forms can be detected: solid, granular, powder, or liquid. The
color and surface structure of the objects are irrelevant. Gases cannot be detected.
Typically, ultrasonic sensors are used in a wide range of applications including:
•Sag control on packaging and metal processing machines
•To measure diameter of roll material (e.g., film, paper, metal sheet)
•To detect fill levels in tanks and silos
•To avoid collisions with self-propelled or controlled machines
•Height control of booms for sprayers
•To detect containers on refuse collection vehicles
•To detect objects or to measure fill levels on conveyor belts
•To detect pallets on forklifts
•To monitor range on barrier systems
•To detect PCBs when feeding them to SMD placement machines
The standard cylindrical 18GS housing design can be programmed and adapted to various
applications. You can program boundaries, output modes, output types, and sound beam width
via the programming buttons on the sensor or via the convenient O-Link or rDa interfaces.
Convenient programming via the O-Link or rDa interfaces makes setting many other parame-
ters such as filter options, echo suppression, synchronization settings, etc. possible. You there-
fore have various channels and adjustment options available for programming that can be used
individually depending on your application.
Programming of the ultrasonic sensors via O-Link is possible offline using ODD or DTM and
an FTD frame program. You can program it online via a PLC via O-Link master and ODD. Pro-
gramming via the rDA interface is possible using a DTM and an FTD frame program.
The O-Link versions with switching output enable O-Link communication in accordance with
the O-Link standard. The 18GS versions with analog output can be parameterized via their O-
Link interface.
The advantages of the UC***-18GS ultrasonic sensors are:
•Proven cylindrical housing design
•Advanced setting options via programming button on the device
•O-Link 1.1 interface for service and process data, and for parameterization
•Excellent immunity to background noise such as compressed air
•Can be self-synchronized to avoid mutual interference of several adjacently mounted
ultrasonic sensors
•Programmable echo suppression
What Is IO-Link?
O-Link enables seamless communication and digital data transfer from the control panel level
down to the sensor level. The intelligent sensors can be used to their full potential with O-Link,
paving the way for ndustry 4.0 in automation technology. The internationally standardized
interface provides value at all stages, from plant design and installation through to operation
and servicing. This value is achieved by sustained cost reductions and efficiency improve-
ments.

UC***-18GS series
Product Description
Standardized device description files (" ODDs") and parameterization via software tools ensure
convenient configuration and integration of O-Link sensors. ntelligent and transparent param-
eter management increases application flexibility and keeps downtimes to a minimum.
Parameters can be customized quickly and easily, even for complex production and batch
changes. Transparency right through to the sensor gives users access to a comprehensive
range of parameterization options and device diagnostics functions, allowing them to perform
predictive servicing.
The technology offers particular benefits
•n service (troubleshooting, servicing, and device exchange)
• During commissioning (cloning, identification, configuration, and localization)
•And during operation (job changeover, continuous parameter monitoring, and online diag-
nostics)
Device Description File (IODD)
The sensor parameters are different for each device. A standardized description of these
parameters can be found in the O Device Description ( ODD). The ODD can be imported into
various engineering tools from different system providers, providing they support ODD. The
sensor can be configured or diagnosed using the appropriate tool.
ODDs can be integrated in a control environment to allow O-Link devices to be used for O-
Link operation. Both programming and exchanging process data can be performed with a PLC.
The ODD can be imported into a range of engineering tools from various system providers for
programming and diagnostics, provided these tools support ODD
DTM (Device Type Manager)
f a sensor is not used long-term in an O-Link environment, but nevertheless needs to be con-
figured, this can be done easily via a PC with installed FDT frame application (e.g., PACTware)
and with the DTM (Device Type Manager, a kind of "device driver") available for the sensor.
Unlike configuration via the ODD, this method provides extended functions and ensures
improved graphic visualization and convenient operation. Functions such as UC***-18GS
series "echo suppression" can only be configured via the relevant DTM.
Offline Parameterization
For offline parameterization, O-Link devices are already configured before mounting. To do
this, use the Pepperl+Fuchs O-Link USB master.
We recommend using the "PACTware" software as an FDT frame application and user inter-
face. So that it can be used in PACTware, the ODD must first be translated via the " ODD inter-
preter DTM" software. " ODD nterpreter DTM" is used to transform the ODD into a tabular user
interface for parameterization.
The software components required in each case are summarized in the most current version of
the " O-Link Offline Parameterization Tool" software package. The software package and the
documentation on its installation and use can be found online at www.pepperl-fuchs.com.
f you use the " O-Link Offline Parameterization Tool" software package, have active internet
access, and have connected your device via the Pepperl+Fuchs O-Link USB master, the
PACTware will automatically find the right ODD online.
The device description file ( ODD) required for integration in an O-Link system and for parame-
terization and diagnosis is available online. Visit www.pepperl-fuchs.com and navigate to the
relevant product page for the UC***-18GS sensor.
Online Parameterization
When commissioning machines and plants, you must integrate master and O-Link devices into
the appropriate control environment. Depending on the components used, different software is
required.
You can configure and parameterize the devices using an O-Link configuration tool. During
operation, you can check the parameters for the O-Link devices, read, and monitor the status
and diagnostic data. O-Link data is integrated into an application program using function
blocks.

5 Sensor Programming via the Programming Button
Basic information about programming
n terms of factory settings, the sensor can only be programmed during the first 5 minutes after
switching on. This time is extended during the actual programming process. The option of pro-
gramming the sensor is revoked if no programming activities take place for 5 minutes. After this,
programming is no longer possible until the sensor is switched off and on again.
When configuring sensors via the O-Link, you can use the DTM to adjust the programming
button’s locking logic. This is done in the "Sensor configuration" menu option, "Local controls"
tab.
When actively communicating via the O-Link interface of the sensor, it is not possible to use
the programming button to program.
The programming activities can be canceled at any time without changing the sensor settings.
To do so, press and hold the programming button for 10 seconds.
Programming via the programming button can take place in the stand-alone mode of a sensor
or also in the synchronized sensor group of several sensors (only for automatic common mode
and multiplex mode). When programming in the synchronized sensor group, there may be a
delay to starting the programming routine, depending on when the sensor in question is next in
line. For the duration of the programming process, the other sensors in the sensor group go into
standby mode (green LED is flashing). Then synchronization mode continues to operate as
normal.
5.1 Programming Switch Points / Limits
ote
Depending on the sensor type, you can program the switch points (SP1, SP2) for sensors with
switching output and program the limits (SP1, SP2) for sensors with analog output using
programming buttons T1 and T2.
Depending on the output, the following programming buttons are used for programming:
•Switching output 1 via programming button T1
•Switching output 2 via programming button T2 (only with UC*-18GS-2EP* sensors)
•Analog output via programming button T2 (only with UC*-18GS- UEP* sensors)
The programming sequence for SP1 and SP2 are identical in both cases and are therefore
described consecutively below. You must carry out the two programming steps separately for
each switching output / analog output. To ease understanding, the programming button is only
called T below.

Figure 5.1
Programming Switch Point 1 / ear Limit (SP1)
f the object is detected correctly during the programming process, the yellow LED flashes
slowly. f no object is detected, the yellow LED flashes at a higher frequency. A flashing red LED
during or when completing the programming process indicates unreliable object detection. n
this case, correct the alignment of the object during the programming process until the yellow
LED flashes. Only then will the settings be transferred to the sensor memory.
1. Position the object at the site of the required switch point / the required near limit.
2. Press and hold the T programming button for two seconds (yellow LED flashes)
3. Briefly press the T programming button (green LED flashes 3 times as confirmation). The
sensor returns to normal operation.
Programming Switch Point 2 / Far Limit (SP2)
1. Position the object at the site of the required switch point / required far limit.
2. Press and hold the T programming button for two seconds (yellow LED flashes)
3. Press and hold the T programming button for two seconds (green LED flashes 3 times as
confirmation). The sensor returns to normal operation.

5.2 Programming Sensor Operating Modes for Switching Output
The sensor features a 3-stage process for programming the sensor operating modes. n this
programming routine you can program as follows:
•A) Output mode
•B) Output logic
•C) Sound beam width
The programming sequence for switching output 1 and switching output 2 are identical and are
therefore described consecutively below. You must perform the programming steps separately
for each switching output. However, the width of the sound beam is generally set only once for
the sensor. You can set the sound beam width while programming switching output 1. To ease
understanding, the programming button is only called T below.
These stages of the process are programmed in succession. To switch from one programming
step to the next, press and hold the programming button for two seconds.
The following graphic illustrates the programming routine:

Sensor Programming via the Programming Button
The red LED is now flashing. The number of flashing pulses indicates the currently pro-
grammed sound beam width:
1x: narrow
2x: medium
3x: wide
The sound beam width is generally set only once for the sensor.
1. Briefly press the programming button to navigate through the sound beam widths in
succession. Use this method to choose the required sound beam width.
2. Press and hold the programming button for two seconds to save all performed settings and to
return to normal operation.
5.3 Programming the Sensor Operating Modes for Analog Output
The sensor features a 3-stage process for programming the sensor operating modes. n this
programming routine you can program as follows:
•A) Output mode
•B) Output type
•C) Sound beam width
These stages of the process are programmed in succession. To switch from one programming
step to the next, press and hold the T2 programming button for two seconds.
To ease understanding, the programming button is only called T below.
The following graphic illustrates the programming routine:
