Remarks
Intended use:
The ultrasonic label forks are
ultrasonic sensors for contactless detection of the gap
between two consecutive
labels on a carrier tape.
Operate in accordance with
intended use!
This product is not a safety sensor
and is not intended as personnel
protection.
The product may only be put into
operation by competent persons.
Only use the product in accor-
dance with the intended use.
To achieve high repeat-
ability, the label tape must
be slightly under tension.
Align the label tape
according to the sensor's
marker "Label center position" (see also marking on
sensor).
The label material used
determines the achievable
precision and the reliability
of gap detection!
Light switching: signal in
the label gap.
Dark switching: signal on
the label.

GSU 14D Ultrasonic label fork
Standard function
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. LED is ON if the sen-
OUT LED - yellow
WAR N LED - continuous red
light
WAR N LED - flashing red
sor detects label gaps. The display is independent
of the output setting.
OFF: error-free operation.
ON: teaching error caused by unfavorable label
material.
Short-circuit at the switching output.
The output is switched to tri-state until the error is
rectified.
Sensor adjustment (teach-in) via teach button
Teach while label tape is passing through (dynamic)
Preparation: Insert label tape into the sensor.
Press the teach button until green and yellow LEDs flash simultaneously
Release teach button.
Advance the label tape through the sensor.
Press the button briefly once more to terminate the teach event, the sensor goes
into standard mode.
3 … 7 label gaps should be advanced through the sensor in order to achieve stable
switching points.
If the teach event is faulty (e.g. unfavorable material combination, uneven transport, jittering during transport), the red LED illuminates. Repeat the teach event. If the fault cannot
be rectified, the label material cannot be detected with the GSU 14D.

After switching on the
supply voltage and after
the delay before start-up
has concluded
(≤ 300ms), the teach
button on the device can
be operated.
The red LED illuminates if a teaching error occurs (e.g. the label cannot be reliably detected due to insufficient signals).
Regardless of the state, the green LED illuminates upon conclusion of the teach event; the yellow LED indicates the current
switching state.
High level on the teach-in input triggers the teach event.
Advance 3 … 7 labels through the sensor.
Sensor remains in teach as long as the high signal is ap-
plied.
At the same time the teach button is disabled with the first
rising edge (0 -> 1).
Attention: The button remains disabled as long as voltage is supplied to the sensor
(until the sensor is switched off).
The edge transition (1 -> 0) terminates the teach
event. The sensor is in normal operation again.
The button remains disabled until the sensor is
switched off.
A rising edge triggers a
new teach event.
The button remains disabled until the sensor is
switched off.
t
Locking the teach button via the teach input
The teach button is disabled with the first rising edge (0 -> 1) on the teach
input.
Attention: The button remains disabled until the sensor is switched free of
voltage (disabled).
