at least 2 seconds to operate the
device. The button can be electrically
disabled to prevent accidental opera­tion.

IGSU 14D Ultrasonic label fork

IGSU 14D standard functions

During operation the sensor is always in this function. The sensor detects label gaps with high precision and speed. This is indi­cated by the yellow LED and the switching output.

Indicators:

ON LED - green Constantly ON when operating voltage is applied.

Indicates the switching signal.

OUT LED - yellow

LED is ON if the sensor detects label gaps.
The display is independent of the output setting.

WARN LED - con­tinuous red light

WARN LED ­flashing red

OFF: error-free operation.
ON: teaching error caused by unfavorable label material,
ALC function outside of the control window.

Short-circuit at the switching output and/or warning output.
All outputs are switched to tri-state until the
error is rectified.

ALC function (auto level control):

In each teach event, the current signal values in the sensor are digitally determined, resulting in the optimum switching threshold
being calculated for maximum function reserve. All values are saved and are non-volatile, retaining their validity as long as the
dynamic parameters of the system remain unchanged and the material is not changed.

Signal changes can result each time the roll is changed, even with labels that are apparently the same. This is caused, for exam­ple, by material variations (material thickness, homogeneity, etc.) which affect the acoustic impedance of the system. Even
changes of the dynamic parameters (e.g. tape tension, middle position, jitter, etc.) can have a negative affect on the function
reserve of the sensor.

The ALC function now automatically corrects the switching threshold in such a way that the maximum function reserve is always
available during operation - the sensor works absolutely reliably and free of errors.

Note

When changing to another type of label, a new adjustment must generally be carried out by carrying out a new
teach-in event.

Warning output

The warning output is activated if the red LED on the device is illuminated. This is the case for the following states:

 Teaching error (see description)
 "ALC function faulty" error (control limit reached: clean device, align and reteach)

easy Teach while the label tape is passing through

Preparation: Insert label tape into the sensor.

 Press the teach button until green and yellow LEDs flash synchronously
 Release teach button.
 Advance the label tape through the sensor at a max. speed of 50 m/min. The

sensor indicates the tape transport by faster simultaneous flashing of the green
and yellow LED.

 Ready.

If sufficient teach values are determined, the sensor automatically terminates the teach
event and goes into standard mode. The transport of the label tape can be stopped
immediately. The number of labels to be transported is always based on the material
combination: from experience, the value is between 2 and 10 labels.

If the teach event is faulty (e.g. unfavorable material combination, uneven transport, jit­tering during transport), the red LED illuminates and the warning output is activated.
Repeat teach event. If the fault cannot be rectified, the label material cannot be detected
with the IGSU 14C.

Static teach on the label carrier without transport

Preparation: depending on the label size, pull off one or more labels from the carrier and
transport the blank area into the sensor.

 Press the teach button until green and yellow LEDs flash alternately
 Release teach button.
 Briefly press the button again to end the teach event

With this teach event, a one-point calibration is performed on the blank carrier. This pro­cess is particularly advantageous because there is no loss of labels during the teach.

Note

With the easy Teach process, a two-point calibration is performed which, with respect to detection reliability,
is generally to be preferred over the static teach.

easyTune – Manual fine tuning of the switching threshold

With homogeneous label material, the signal in the gap between two labels is
much larger compared to the signal on the label. For the taught switching thresh­old, there is a high function reserve in both the gap as well as on the label, and
the sensor functions reliably.

To achieve a better function reserve, it can be advantageous to change the
taught switching threshold, especially for inhomogeneous label material. Used
for this purpose is the easyTune function, which is similar in principle to a poten-
tiometer. The switching threshold can be adjusted by pressing the button quickly
or for a longer period of time.

Pressing the teach button quickly (2ms … 200 ms) reduces the switching
threshold slightly; pressing the button for a longer period of time

(200ms … 2s) increases the switching threshold slightly. The change resulting
from each press of the button is small. The button may need to be pressed sev­eral times in order to achieve a stable operating point. The sensor confirms each
press of the button with short or long flash of the green LED. If the upper or lower
end of the adjustment range is reached, the green and yellow LEDs flash at a
considerably faster frequency and the red LED is illuminated for one second.

Please note:
easyTune deactivates the ALC function!

Observation Change to the switching threshold Measure

After teaching, the yellow LED and the switching output flicker if the label is moved
through the sensor, i.e., the function reserve on the label ( (C ) in the example) is too
low.

In rare cases, a highly inhomogeneous carrier tape can affect the functional reliabil­ity. The yellow LED and the switching output flicker if the blank carrier tape is moved
through the sensor without labels, i.e., the function reserve on the carrier is insuffi­cient.

Decrease

Repeatedly press the teach button for a lon­ger period of time until the sensor detects

the moving label stably and without interrup­tion.

Repeatedly press the teach button quickly
until the sensor detects the moving carrier
tape without labels stably and without flick­ering.

Notices for integrating the sensor in a control concept

If the sensor is taught externally via a control, it may be necessary to receive acknowledgment from the sensor with respect to
its current teach state. Use the following chart for this purpose:

Operating mode Reaction from sensor

Dispensing mode Dynamic output signal: alternates between gap and label
Teach Static output signal: the state prior to the teach event is frozen (output in tri-state)
Teach OK Output signal is dynamic again—warning output not active
Teach faulty Output signal is dynamic again—warning output active; repeat teach event if necessary

Locking the teach button via the teach input

A static high signal ( 4 ms) at the teach input locks the teach button on the
device if required, such that no manual operation is possible (e.g., protec­tion from erroneous operation or manipulation).

If the teach input is not connected or if there is a static low signal, the button
is unlocked and can be operated freely.

The extended carriage (part no. 50114056)

The carriage can be shortened at any point.

Alternatively, the sensor can also be delivered in the ver­sion with factory-mounted carriage (see order guide).

IGSU 14D

Tape guide

The correct transport of the label tape is decisive for the
switching accuracy and the operational safety of the sen­sor.

To achieve an optimum result, a tape guide was devel­oped for the sensor.

Adjusting the tape holder:

If correctly adjusted, the tape more or less follows the
contour of the carriage and the label tape slides over the
lower fork of the forked sensor (see also figure "Marking
on the sensor" on page 2).

We recommend the use of forked sensors with factory­mounted tape guide (see order guide).
