Functional principle

An ultrasonic transmitter in the lower
tine of the fork beams a fast se­quence of pulses through the back­ing material. The sound pulses cause
the backing material to vibration, so
that a greatly attenuated sound save
is beamed from the opposite side.
The receiver in the upper tine of the
fork receives and evaluates this
sound wave.
The backing material transmits a dif­ferent signal level from the level with
label or from a splice. The difference
between the backing material and
backing with label or the web mate­rial and splice can be very subtle. To
ensure reliable detection, the esf-1
sensor must therefore initially learn
the signal level for the backing or
web material.
The esf-1 sensor can be used as a la­bel sensor or a splice sensor.
With its three Teach-in methods, the
esf-1 sensor can optimally be ad­justed to any task configuration.
With QuickTeach, there is also a sim­plified Teach-in procedure available.

Ultrasonic-Sensors

Product description

■ Assured detection of labels made
of paper, metal or (transparent)
plastic.

■ Detection of splices of paperwebs,
plastic webs or metal webs.

■ Detection of materials with
weights from <20 g/m2 to >>400
g/m2; sheet metals and plastic
films up to 0,2 mm thickness.

■ 3 Teach-in methods + QuickTeach.

■ Parameterisable with LinkControl.

■ Response time of 300 µs until la-

bel/splice is detected.

■ Two fork depths of 67 mm and
150 mm.

Safety tips

■ Read instruction manual before
commissioning.

■ Connection, installation and ad­justment may only be carried out
by trained technicians.

■ Not a safety component as de­fined by the EU Machinery Directi­ve.

Installation

 Install the esf-1 in such a way that

the tine with the button is on top.
This installation orientation per­mits you to keep the measuring
track optimally clean.

 Connect the connection line with

the 4-pin M8 connector as shown
in Fig 1, and that with the 5-pin
M12 connector as shown in Fig. 2.

Commissioning

 Turn the power supply to the esf-1

on.

Teach-in with push-button
and control input

The Teach-in process can optionally
be carried out with the button on
the top tine of the fork or with the
Teach-in input on pin 5 on the M12
connector or pin 2 on the M8 con­nector.

Pointer

■ The Teach-in/Com control input is
parallel with the push-button.

■ +UB connected to the control in-
put correponds to a key press.

Standard Teach-in

There are 3 Teach-in methods avail­able:

■ Dynamic Teach-in of label

■ Separate Teach-in for backing ma-

terial and labels

■ Splice sensor

QuickTeach

With QuickTeach, you have a simpli­fied Teach-in process that you have
to activate once before initial com­missioning.

Pointer

■ To use QuickTeach, you have to
decide whether the sensor will act
as a label or a splice detector.

■ Once QuickTeach is activated, you
can't switch between NCC/NOC
any more.

■ The QuickTeach functionality is
available for sensors with lot num­bers > 12xxxxx.

 Insert the web material into the

fork and carry out one of the three
standard Teach-in methods or
QuickTeach.

Working

The esf-1 continually performs meas­urements and sets the switched out­puts based on its results.

Factory setting

The esf-1 sensors have the following
settings configured at the factory:

esf-1/CF

■ Label/splice output F on NOC.

■ QuickTeach is deactivated.

esf-1/CDF and esf-1/15/CDF

■ Label/splice output F on NOC.

■ Output D2 on web break display.

■ Output web break on NOC.

■ QuickTeach is deactivated.

Synchronisation

If multiple esf-1 sensors are operated
in tight quarters, they can influence
one another. To avoid this, the esf-1
sensors can be synchronised. To do
this, all Teach-in/com control inputs
are connected together (see Figs. 1
and 2 for the connector pinouts).

Pointer

■ A Teach-in using the control input
can also be carried out with syn­chronisation active.

Parameterisation with Link­Control

The esf-1 can be extensively parame­terised with LinkControl. To do this,
you need the optionally available
LCA-2 LinkControl adapter and the
LinkControl software for Windows©.

Use in LinkControl

 Install the LinkControl software

onto your PC.
Connect the LinkControl adapter
to your PC using the USB cable.

 Connect esf-1 to the LCA-2 as

shown in the table in Fig. 4.

 Connect the cable for the power

supply to the LCA-2 on the other
side of the T plug.

 Start the LinkControl software and

follow the instructions on the
screen.

Fig. 4: Connection of esf-1 to the LCA-2

You can change the following set­tings:

■ NOC/NCC function of the
switched outputs.

■ Switched output function D.

There is also a graphical representa­tion of the measured values avail­able.

Maintenance

The esf-1 is maintenance-free. For
significant deposits of dirt, we rec­ommend carefully blowing out the
measuring track with clean, oil-free
compressed air.
