Adjustment Guide
The environments in which
capacitive sensors are
in stall ed can often be
un
stable as regards to tem-
perature, humi dity ,
object distance and industrial (noise)
inter ference. Because of
this, Carlo Ga vazzi offers
as standard features in all
TRIP LESHIELD™ capacitive sensors a user-friendly
sensitivity adjustment instead
of a fixed sensing range.
Likewise, these sensors
provide an extend ed sensing range to accommodate

The functions described in the Teach-in
guide can be set up by means of the teach-in
wire.
It is possible to teach-in several sensors at
the same time by connecting the WH-wires
in parallel to the common ”BU -” supply.

Installation Hints
Capacitive sensors have
a unique ability to detect
al most any material in
li quid or solid form. Capaci tive sensors are able to
detect me tallic as well as
non-metallic ob jects. However, their traditional use is
for non-metallic materials
such as:
• Plastics Industry
Resins, regrinds or mould-
ed products.
• Chemical Industry
Cleansers, fertilizers, liquid
soaps, corrosives and
pe t ro chemicals.
• Wood Industry
Saw dust, paper products,
door and window
frames.
• Ceramics & Glass
Industry

Teach functions
Normal operation, optimized switching point
1. Mount the sensor in the application without the target
present. Yellow LED is not important and green LED
is ON.
2. Press the button for 3 seconds until both LEDs
are flashing simultaneously.
(The background is stored)
3. Place the target in the detection zone.
4. Press the button once and the sensor is ready to
operate (green LED ON, yellow LED ON)
(The second switch point is stored).
If the target is too close to the background, the
sen
background and the LEDs will alternate 3 times.
For maximum sensing distance (default setting)
1. Mount the sensor in the application without the target
present. Yellow LED is not important and green LED is
ON.
2. Press the button for 3 seconds until both LEDs
are flashing simultaneously.
(The background information is stored)
3. Press the button a second time and the sensor is
ready to operate (green LED ON, yellow LED ON)
(The sensor is set up with the maximum sensing
distance that is not influenced by the background).
sor will perceive both background and object as
For dynamic set-up (running process)
1. Line up the sensor at the target. Green LED is ON,
status on the yellow LED is not important.
2. Press the button for 3 seconds until both LEDs are
flashing simultaneously.
3. Press and hold the button a second time for at least
one second (both LEDs are flashing simultaneously
and fast) and keep the button pressed for at least one
process cycle. Release the button and the sensor is
ready to operate (the switch point is stored into the
sensor and is optimized respecting both background
and target information).
A more precise setting is possible if several process
cycles are analysed.
For make or break set-up (N.O. or N.C.)
1. Press the button for 10 seconds, until the green LED
flashes.
2. While the green LED flashes, the output is inverted
each time the button is pressed. Yellow LED indicates
N.O. function selected.
If the button is not pressed within the next 16
seconds, the current output is stored.
Factory settings
Press the button for 16 sec.
