Part number code
ALC (Auto Level Control) function ((I)GS63B/….3…)
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 permanently saved, 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 (transmission factor, homogeneity …) or changes of the dynamic system parameters (e.g. tape tension, middle position
of the labels, jitter, etc.) that can have a negative affect on the function reserve of the sensor.
With the ALC function, the sensor 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.
The teach event only needs to be repeated if the sensor does not switch following a change of material.

Sensor adjustment via potentiometer for GS 63B
Note: A removable operating button is plugged on the potentiometer in ex works. The setting of the fork
photoelectric sensor can thereby be performed manually and without the need for a tool. If this is not
desired, the operating button can be pulled off – a screwdriver is then necessary for making adjustments.
The following description applies to a fork photoelectric sensor with switching signal in the label gap
(GS 63B/6…). For device versions with switching signal on the label (GS 63B/6D…), the LED indicators
are inverted.
Preparation: Remove one or more labels from the base material and advance this blank area into the sen-
sor.
- If the yellow OUT LED does not switch on when the blank area is encountered, increase the sensi-
tivity by turning the potentiometer clockwise until the yellow OUT LED switches on.
- Starting from this setting, turn the potentiometer clockwise another approx. one half turn.
- Now advance the label tape so that a label is in the sensor.
- If set correctly, the yellow OUT LED must now switch off. Reduce the sensitivity by turning counter-
clockwise if the LED remains on.
- Finished: if set correctly, the LED changes between gap and label.

Standard function for (I)GS 63B
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:
Operation:
The teach button must be pressed for at least 2 seconds to operate the device. The button can be electrically disabled to prevent acci-
dental operation.
Sensor adjustment (teach-in) via teach button for (I)GS 63B
For optimum adaptation to various labels, the fork photoelectric sensor features two different sensitivities. The standard sensitivity
(2 … 7s) functions with very many labels and is always the first choice.
Only in the event of faulty switching on the label, e.g., with slightly transparent (translucent) or strongly inhomogeneous label materials,
is teaching on level 2 "Sensitive" (7 … 12s) recommended.
The teach-in can always be performed dynamically while label tape is passing through or, if the label tape cannot be transported, statically.
Preparation for dynamic teach-in:
Insert label tape into the sensor.
Preparation for static teach-in:
Remove one or more labels from the base material and advance this blank area into the sensor
Press the teach button until green and yellow LEDs flash simultaneously.
Release teach button.
During the teach event, the switching output is frozen in the most recently valid state prior to teaching.
Dynamic teach-in:
Advance the label tape at a maximum speed of 20m/min through the sensor so that at least 3 … 7 labels pass through the
sensor.
Static teach-in:
Blank area remains at the same position in the sensor.
Press the button briefly once more to terminate the teach event, the sensor goes into standard mode.
If the teach event is faulty (e.g. transmission with insufficiently thick base material), the red LED illuminates, the green and yellow LEDs
flash rapidly and the warning output is activated. For error acknowledgment, briefly press the teach button and repeat the teach event. If
the fault cannot be rectified, the label material cannot be detected with the (I)GS 63B.
Adjusting the switching behavior of the switching output
(signal in the label gap/on the label)
Press teach button until only the green LED flashes with 3 Hz.
Release the teach button - the green LED continues to flash, the yellow LED alternates slowly between ON and OFF.
Yellow LED ON = output switches in the label gap
Yellow LED OFF = output switches on the label.
If the button is pressed again while the LED is ON, the device switches in the label gap. For control purposes, the switching
behavior is displayed as long as the button is pressed. If the output is to switch on the label, the button must be pressed while
the LED is OFF.
Ready.
ON LED - green Constantly ON when operating voltage is applied.
OUT LED - yellow Indicates the switching signal. LED is ON if the sensor detects label gaps.
The display is independent of the output setting.
WARN LED - red Is OFF if operation is error-free. If the "Control limit reached" message appears or if the last
teach event was faulty, the red LED illuminates.

Sensor adjustment (teach-in) via teach input for (I)GS 63B
The following description applies to PNP switching logic!
The device setting is stored in a fail-safe way. A reconfiguration following power failure or switch-off is thus not required.
Line teach while label tape is passing through
Preparation: Insert the label tape in the correct position in the sensor (align the middle of the tape to the sensor marking).
The red LED illuminates and the warning output is activated if a teaching error occurs (e.g. the label cannot be reliably detected due to
insufficient signals).
Regardless of the state, the green LED is on when the teach event is terminated, the yellow LED indicates the current switching state.
Line teach if the label tape cannot be advanced (static teach)
Preparation: Remove one or more labels from the base material and place this blank area in the sensor. The label tape must now not be
advanced further.
The process is identical to the line teach with moving label tape.

Storing teach values in the sensor
It is possible to store or retrieve up to 30 different teach values. In this way, various label materials can be processed without the operator
needing to perform a teach event. If this function is desired, static interlocking of the teach button is recommended so that no operation
of the device can occur.
The event starts with the execution of the line teach (see description on page 6). The teach value ascertained in this way remains in sensor
memory and is then stored in one of 30 possible storage places using the process described in the following.
Flow chart: First perform line teach, then store teach value.
Storing teach values
Reading out teach values
Locking the teach button via the teach input
(I)GS 63B
A static high signal on the teach input locks the teach button on the device so that
no manual operation is possible (e.g. protection against 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.
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:

Mechanical accessories
Flat mounting device – for mounting compatibility with GS 06 fork photoelectric sensors
High mounting device – for uniform tape height with (I)GSU 14 ultrasonic fork sensors
Clamp – for installation in a groove directly at the dispensing edge
Maintenance information
The (I)GS 63B fork photoelectric sensor is largely maintenance free. Depending on the environmental conditions and the used materials,
it may be necessary from time to time to clean the transparent parts in the lower and upper fork of the fork photoelectric sensor. We rec-
ommend using a soft, moist cloth for this purpose. To protect the surface, cleaning agents containing solvents should not be used for
transparent parts.
Environmental durability
The used materials feature very good resistance to weak acids and bases as well as to UV exposure. Contact with organic solvents is
possible only to a limited extent and only for short times. Resistance to chemicals should be examined on a case by case basis.
Mounting device BT-GS6X.L (part no. 50114381),
flat design, especially for mounting compatibility with
our GS 06 fork photoelectric sensors.
Mounting device BT-GS6X.H (part no. 50123869),
high design, especially if it is desired that the tape
pass through at a uniform height between our
(I)GSU 14 and the GS 63B.
The BT-GS6X.DT clamp (part no. 50128583) is re-
quired for fastening the sensor at an arbitrary posi-
tion in a groove. Connect clamp to sensor as shown
and secure at the desired position by uniformly
screwing in the stud screws.
