2. Description  
CAUTION! - The machine is connected to mains. Only authorised personnel  
may open the cover. Operation without this cover is not allowed.  
This chapter explains the structure and the function of the labeller. The expressions used are  
explained here.  
2.1 Mechanics  
The labeller is available in a right-hand or a left-hand version. The expression right or left is  
related to the direction of product transport.  
The material is unwound from the label roll (3). The maximum diameter of the label roll is 300  
mm. The width of the backing paper is 155mm for a 330 and 230mm for a 430 machine. The  
label roll is guided by a swing away lever (4).  
The dancer arm (011) keeps the material tight and the acceleration forces low. The deviator  
roller (8) allows the use of inside or outside wound label web. The deviator roller (9) guides the  
material to the dispensing edge. Paper brake brush (6) applies a brake force to the label web  
and keeps the label web under a certain tension without disturbing the movement. At the  
dispensing edge (10) the label sensor (15) is mounted. It detects the gap between the labels.  
The sensor includes a light source and a light receiver. The software can adjust the sensitivity.  
With this information, the machine calculates the position of the label. At the dispensing edge  
(10) the label is separated from the backing paper and moved to the product. With a foam roller  
(16) in front of the dispensing edge, the label is applied to the product.  
The deviator rolls (5) guides the backing material to the drive roller (1).  
The drive roller (1) moves the label web according to the adjusted dispensing speed.  
The pressure roll (12) has to be positioned in the centre of the label web, in order to guide the  
web straight on track. By means of the knurled screws, the pressure roller is held in its required  
lateral position on the shaft.  
With its handle the pressure roller (12) will be opened and closed. When inserting the material  
the pressure roller has to be opened.  
The deviator roller (17) guides the backing paper to the rewind mandrel (13). The rewind  
mandrel should always be set to expanded position when mounting a new roll of labels. This  
allows an easy removal of the collected backing material.  
To ensure a reliable run of the label web the guides (18) have to be adjusted according to the  
width of the labels in use.

3. Preparing the machine  
In this chapter you will learn how to install and adjust the labeller. After this step has been  
completed you will be ready to learn how the labeller's parameters can be adjusted to suit your  
particular production requirements.  
3.1 Installation  
3.1.1 Unpacking of the unit  
For removing the unit off the box, don’t hold the machine on the dispensing edge to prevent  
disadjustment off the machine.  
For mounting the machine, a complete system of holding tools is available. Ask your  
representative.  
Take care that the machine is safe and stable mounted.  
There are rotating parts on the machine. Do the necessary actions to prevent that anybody  
can be caught from these parts.  
3.1.2 Connection of the machine  
Before connecting the machine to the mains, check the correct setting of the line voltage. For  
the connection of sensor, applicators e.g. see the chapter connections. Fix all cables to prevent  
accidents and damaging of cables. Have also a look to the EMI chapter for proper machine  
operation.  
For checking of correct operation of sensors, applicators use the check functions SCHK, I_CH  
and O_CH.  
3.1.3 General setting  
Normally the setting is done, but before operation check and note the general dispenser  
configuration: dispenser direction, machine type, applicator mode, and APSF function.  
3.2 Prepare dispensing  
3.2.1 Insert material  
Insert your label material in the machine to follow the instructions in the chapter Operation /  
Threading.

ALS 330/430  
3.2.2 Define label data  
For correct dispenser operation, you have to tell the machine the length of the label and adjust  
the label sensor. Normally this is done automatically. For this follow the instructions in chapter  
Operation / Initialise material.  
There are some reasons the automatic initialisation is not possible:  
1. Using another then the standard optical label sensor  
2. Label material with a low contrast ratio between label and backing paper  
3. Labels with holes inside the label  
In this case, you have to set one or both of the parameter manually.  
Activate the extended standard menu to do the settings by:  
y
Pressing both keys NEXT and PRIOR simultaneously  
Display: CODE

Setting the label length  
Enter the LPIT function by pressing ENTER. Measure the distance from one label edge to  
the edge of the next label. Enter the value in mm by using the function keys. Press ENTER  
to leave the function. See also the information below.  
Change the setting of the label sensor  
If another label sensor then the Wenglor type will be used, call the CONT function and set  
the value to any manual value (e.g. M006.).  
If the contrast ratio is low, follow the instructions to adjust manually contrast.

3.2.3 Capacitive label sensor  
For transparent labels the standard photo label sensor doesn’t work. In this case, use a  
mechanic or a capacitive label sensor.  
Note: For correct automatic initialisation, the CONT parameter has to be set to a  
manual value, if you using not the standard photo sensor.  
A mechanical sensor is limited in the speed. The bounce at the label edges produces wrong  
signals.  
There is optional a capacitive label sensor available (Leuze GK14/24L).  
Adjustment of the sensor is carried out as follows (Figure 5):  
1. Set sensitivity to maximum by turning the Potentiometer clockwise. Then rotate ½ turn  
anticlockwise.  
2. Remove label material out of sensor.  
3. Perform base adjustment, that both LED “base adjustment” have the same brightness.  
4. Put label with backing paper inside the sensor. Doing this, the LED “switch output” and the  
left LED “base adjustment” are switched off. With backing paper only in the sensor both  
LED are switched on. If the LED are lightning with label inside the sensor, increase  
sensitivity in ¼ turn steps by rotating the sensitivity clockwise.  
5. Check the adjustment over the complete length of label.  
Carry out the above adjustment after mounting, cleaning or increasing sensitivity.

3.3 Label guide  
On some of the axles, they’re guiding clamps. Adjust the clamps near the machine so all have  
the same distance to the front plate (31.5mm). The outer clamps should be mounted that the  
guide but not bend the label material.  
The front of the V-dispensing edge has a rot, which can be adjusted for straighten the material  
guiding. Spend several labels by pressing the dispenser FEED key. If the material guiding is  
running out of the guiding way, adjust the rot by loosing two screws at the dispensing edge.  
With a L-dispensing the adjustment is done by move the tail sheaves behind the dispensing  
edge.  
3.4 Adjust dispense function  
For an operation without any trouble and high label accuracy, tree adjustments are required:  
Label position on the dispensing edge: stop position  
Dispense speed  
Label position on the product  
The adjustment should be done in the same order, because parameter like the stop position  
depends on the setting of the stop position and the dispensing speed.  
3.4.1 Stop position  
The first step is to adjust the stop position. This is the basic adjustment of the dispense  
process. Also in case of problems with the machine check if the stop position is okay.  
Figure 6 Stop position  
The stop position should be adjusted so that the label stops at the dispensing edge up to 3 mm  
behind.  
For a correct operation of the automatic label compensation, they will compensate a missing  
label on the web, first the distance between label sensor and dispensing edge has to be  
defined. Do this by calling the DIST function in the configuration menu. Check the setting by  
removing a label before the label sensor from the web. Give a start signal to the machine by  
triggering the start sensor (not the FEED key) and see if the compensation is done on the right  
position. Do the fine adjustment with the STOD function.

ALS 330/430  
3.4.2 Fixed dispensing speed  
The second step is to adjust the dispense speed. If an APSF sensor is used see 3.4.3.  
If an applicator is used, then the dispense speed has no influence to the dispense process.  
Set POS to the distance between start sensor and dispensing edge. If installed remove the  
roller to press the label onto the product. Now try to dispenser one product. If the label has  
wrinkles reduce the speed VELO. If the product peels out the label, so the stop position of the  
next label is different to the last position increase the speed. Normally your dispense speed  
should be a little bit higher than your product speed.  
3.4.3 Automatic dispensing speed (APSF)  
With a connected rotary encoder, the dispensing speed follows the measured product speed.  
To adjust the speed use the EGRA function located in the extended standard menu. The  
measured speed will be displayed in the VELO function. Do the adjustment in the same way  
described for fixed speed.  
3.4.4 Label position on the product  
At least adjust the position of the label on the product with the POS function or with the STAD  
function, if an applicator is in use.  
3.4.5 Product data bank  
Save your setting in one of the product data banks. If different products and / or labels are in  
use up to nine different combinations could be stored. Define and store the different product  
data. The select the product data bank mode by holding the PRIOR key during power on.  
Switch back to normal mode by holding the NEXT key.

4.3 Initializing new label material  
The machine requires data of the label material in use i.e. label length and opacity of the label  
and backing material. In most cases, those parameters can be scanned during automatic  
initialisation. This is not always possible.  
During initialisation, the machine uses its label sensor to determine where the labels are on the  
label web and the distance between the leading edge of labels (the label pitch) so that they can  
be positioned correctly.  
There are several modes of initialisation:  
y
y
Automatic mode: The machine measure the setting  
Manual mode: The operator measures the label parameter and keys in the values.  
In most cases, initialisation should be executed in fully automatic mode. For fully automatic  
initialisation, the "LPIT" and "CONT" parameters should be set to "AUTO". Initialisation can be  
executed by pressing the <FEED key> whenever the message "INIT" is displayed by the  
machine.  
The message "INIT" is displayed in the following cases:  
a) if the <FEED> key is pressed and held during power up  
b) on return to the standard menu after the "CONT" or "LPIT" parameters have been changed  
to automatic mode  
c) on return to the standard menu after the configuration menu has been used  
d) after clearing the error messages E__0 or E__1 in the standard menu. (If the feed key is  
pressed while another parameter is displayed, the data from the last initialisation is held  
and the first label edge detected is simply moved to the position defined by the "STOD"  
parameter)  
To start initialisations simply press the <FEED> key when "INIT" is displayed.  
The machine will slowly feed the label web while it searches for the gaps between labels and  
measures the label pitch. When the machine has determined this information it will move the

first label edge found during the initialisation process to the position that has been adjusted with  
the "STOD" parameter. After initialisation has been completed successfully, "ON" is displayed.  
Initialisation can only take place in the standard menu; it is not required in the product menu  
since all label data is already stored in the machine's memory. After a E__0 or E__1 message  
has been cleared whilst in the product menu the first label edge detected at the next press of  
the <FEED> key will be moved to the position defined by the "STOD" value stored in the  
machine's memory.  
However, when changing to a new product bank or changing label rolls the FEED key should  
be pressed once so that the label sensor can find the next leading label edge and move it to the  
correct dispense position previously defined by the STOD parameter

If you do not press a panel key while turning on the machine the same menu is active that has  
been used before the machine was switched off.  
4.4.2 Missing label function and web breaks  
The missing label function stops the label web in the correct position even when a label is  
missing from the label web. If there are more than 3 missing labels from the web then the  
machine will stop and give the correct message E_1.  
If the label web has broken or come to an end then the machine will no longer be able to find  
the next leading label edge and so after more than 3 signals from the product sensor the error  
message E_1 will also be generated.

A new initialisation of material is necessary. Pressing the FEED key will start the initialisation.  
Label position ____________________________________________________POS  
The position of the label can be changed by the parameter POS while the machine is in  
operation. The display is presented in 1/10 mm and means the distance between product  
sensor and labelling position of the product. The display value 0500 would mean 50.0 mm. By  
pressing the key PRIOR the value is increased, i.e. the label is put on later. By pressing the key  
NEXT FUNCTION the value is decreased and the label is put on earlier.  
The labelling position is also changed by variation of the product speed. In this case first control  
you product speed and the dispense speed VELO. Only if both speed matches adjust the  
position with the POS function.

Stop position ___________________________________________________ STOD  
The stopping position (STOD) defines the position where the label stops after it has passed the  
label sensor. The value represents 1/10 mm. In the example 0160 has to be adjusted by  
pressing the FUNCTION keys. If an increased value is chosen, the label is advanced further, in  
case of decreased values the position is closer to the label sensor.  
Figure 16 Stop position  
Dispense speed __________________________________________________VELO  
The speed value VELO displays the dispensing speed in 0.1 m/min. The product conveyor  
speed has to be constant to assure accurate labelling. A change of the product speed causes a  
different position of the label on the product. In case of inaccurate labelling, it should be  
verified, if the speed of the dispenser and your product match together. This is done  
automatically if the optional automatic speed follower (APSF) is installed.  
If the machine is equipped with an applicator, two parameters in the standard menu can be  
changed. The delay time which specifies the moment when the applicator must put the label  
onto the product and the blow time - how long the applying of the label should take.  
Start delay_______________________________________________________STAD  
By the aid of the parameter STAD the period of time between the recognition by the product  
sensor and the dispensing of the label onto the product is determined. The time units are ms,  
the time is adjusted by the keys FUNCTION.

ALS 330/430  
Blow on time ___________________________________________________ BLOW  
The labelling time BLOW indicates, for how long the applicator should apply the label onto the  
product. This time is displayed in ms also. BLOW is equivalent to APT2, which is found in the  
extended menu.  
Product menu____________________________________________________ PD0n  
This menu can be used for storing data for different labels and products. 15 different sets of  
product data can be programmed.  
If you want to switch to another product, select the respective product number by pressing  
NEXT and PRIOR, then press ENTER. Now the new product data are activated.  
To change the labelling parameters you can call the extended menu. After leaving this menu,  
your product data will be automatically updated.  
The labeller carries out the labelling of your products completely automatically.  
Check now and then:  
if there is still enough labelling material on the unwind roll  
if an error has been displayed and the machine no longer effects labelling  
if the label is placed correctly onto the product. If this is not the case, correct the respective  
parameter in the standard menu.  
Control is even simpler if you use an OD-control. The OD-sensor measures the diameter of the  
material roll and indicates a warning message W__5 as the label roll diameter gets too small,  
i.e. there are only a few labels left on the label roll. To the warning output, you may connect an  
alarm indicator, an optical or acoustic signal can be triggered.  
4.5 Maintenance  
The machine can be easily maintained and has only a few wear parts. If you change the  
material, note if any glue or waste labels are stuck on the rolls or dispensing edge. In this case  
you have to clean the respective parts. The machine has to be cleaned at least once a week.  
Glue and waste labels have to be removed from the rollers, the dispensing edge, the material  
brush, and possibly from the applicator. All rollers have to be cleaned from any grease. We will  
supply a special cleaning set for this. The material label sensor has to be cleaned from dust  
regularly. The material brush should be turned around whenever the material is changed. Any  
glue has to be removed from the brush. If there is a soft roller at the dispensing edge for  
applying the label to the product, check if the roller is damaged or dirty. Replace it if necessary.  
The unwind has to operate in such a way, that the dancer arm does not bounce to its end  
position. If this is not the case, the friction mechanism has to check.  
If the backing paper is not wound up accurately, the belts have to be tightened.  
Check the electrical connections, especially the mains cable for unreliable connection.

5. Menu structure  
The touch panel keys or the optional interface can change labeller parameters. The last  
entered parameters are the actual ones the machine works with. Programming via the interface  
is described in chapter Serial interface.  
There are 2 levels for parameter adjustments. The first one is for parameter selection. With the  
keys FUNCTION a parameter is selected. By pressing the keys ENTER the second level can  
be reached. Pressing the keys FUNCTION can change the parameter values. By pressing  
ENTER you quit the parameter adjustment and the next menu point is shown. For some  
functions the change of values is effected immediately, for others when leaving the menu point.  
Details in the menu functions.  
There are 4 different menu structures:  
Standard menu  
This menu is used for normal operation. The most important parameters for the production  
can be changed here. The adjustments are lost after turning off the machine.  
Extended standard menu  
This menu offers additional parameters and functions to those in the standard menu. Any  
adjustments made in the extended menu are stored on quitting the menu and are  
maintained even if the machine is then turned off.  
Product menu  
If data banks are stored in the extended menu, the product menu can be activated. In this  
menu, programmed data banks only can be selected. Changing parameters in this menu is  
not possible. When storing data in a new data bank, the current adjustments are saved to  
the new product data bank. You may change data values of a stored data bank by loading  
the data from the extended standard menu, modifying them and resaving them in a data  
bank.  
Configuration menu  
In this menu, you configure the machine according to your applications. Additionally you  
have access to service test functions. This menu is mainly dedicated to service technicians.  
All current parameter settings are stored on quitting the configuration menu and are  
maintained if the machine is then turned off.

Stop position ___________________________________________________ STOD  
Function: Stop position of the label at the dispensing edge.  
Available: Always  
Range: 0.0 .... 200.0 mm  
Product length ___________________________________________________PRDL  
Function: The product length avoids multi labelling in case of difficult products. Normally it is set  
to AUTO. This means that the product length is set to the label length.  
After the product sensor has detected the edge of the product all signals that might be triggered  
while the product is passing the product sensor are inhibited. This function can be helpful in  
cases where the product is transparent or has several detection marks or edges. Such a case  
is shown below.  
The product sensor supplies several signals while the product passes the product sensor. If the  
PRDL is not adjusted according to the dimension of the actual product the warning W_0 may  
be given of false multiple product detection signals. The defined product length suppresses all  
signals after the first product sensor signal has been received.  
By pressing the keys FUNCTION the parameter PRDL is selected. The data input is selected  
by pressing the key ENTER.  
If an applicator is fitted to the labeller, the product length is not defined as a distance but as the  
time that the product needs to pass the product sensor. The time is adjustable between 5 and  
9999 ms.

Only available if applicator is used.  
Range: 1 to 9999 ms  
Dispensing speed ________________________________________________VELO  
Function: The labelling speed may be adjusted with the parameter VELO. Values between 0.2

speed.  
When an applicator is fitted to the machine, this parameter defines how fast the label will be  
dispensed on to the applicator.  
EGRA value check________________________________________________ STST  
Use this function to adjust the EGRA value. If the drive-roller speed is higher than that of the  
conveyor then increase the EGRA value, if it is lower decrease the EGRA value so that the  
conveyor speed and drive-roller speed match.  
Slew speed _____________________________________________________ SLEW  
Function: For some situations the labeller can run with a different, higher speed. This occurs  
during compensation of a missing label on the web, positioning the label at the dispensing  
edge during initialisation or after pressing the feed button if the APSF-mode is selected. The  
resulting speed depends on the selection (FAST or SLOW) and the APSF-mode.

Electronic gear ratio adjustment ___________________________________ EGRA  
The parameter EGRA appears in the extended menu only after the APSF function has been  
switched on.  
The range of the EGRA parameter is 100 to 500, representing from 1 to 5 encoder pulses per  
millimetre of conveyor movement. The full EGRA range can be used up to 30 m/min conveyor  
speed.  
With an applicator there is no realistic limit to the conveyor speed and at very high-speeds an  
EGRA value at the lower end of the range should be used.  
Dwell time_______________________________________________________ APT1  
Function: Only used when an EP- applicator is necessary. It defines for how long the pneumatic  
cylinder is switched on.  
Available only with applicator.

Blow on time_____________________________________________________ APT2  
Function: Only used when an applicator is necessary. It defines for how long the label is blown  
onto the product.  
Available only with applicator.  
Range: 1 ... 7500 ms  
Restart delay ____________________________________________________ APT3  
Function: This parameter defines the time for a next label dispense after the applicator cycling  
is completed.  
Available only with applicator.  
Range: 0 ... 5000 ms  
Time constant compensation_______________________________________ APT4  
Used to control the labelling position when using an applicator in conjunction with APSF.  
The parameter APT4 is set to the time that the label takes to reach the product from the start of  
the applicator cycle. For blow applicators this will probably be less than 25 ms, for EP (air-  
cylinder) applicators the time will be much more - possible 60 ms to 100 ms depending on the  
length of the air cylinder.  
To calculate the correct value proceed as follows:  
Set APT4 to 1. Run the conveyor at a fairly low speed such as 10 m/min and note the label  
position on the product. Now run the conveyor at a much higher speed such as 25 m/min and  
note how far the label position has shifted back.  
Use the following formula to calculate the correct value for APT4...  
(LABEL SHIFT (mm) x 60) / (Vhigh - Vlow) = APT4  
Vhigh represents the higher conveyor speed used (in m/min)  
Vlow represents the lower conveyor speed used (in m/min)  
eg. If the shift is 3mm and the conveyor speeds 10 m/min and 25 m/min are used the correct  
value for APT4 is:  
(3 x 60) / (25 - 10) = 180 / 15 = 12  
The calculated value should then be tested by running the conveyor at a high and a low speed  
and checking that the placement position does not change. If the label position moves back  
slightly at higher speed then increase APT4 a little, if it moves forward at higher speed then  
decrease APT4 a little.  
Note: The EGRA parameter must be set correctly as well as the APT4 parameter  
for correct label positioning on the product.

5.3 Product menu  
If parameters have to be changed because of different products and labels, the product menu  
can be used. The machine offers a data bank in which 14 sets of data can be stored.  
If you want to switch to a particular product, select one of the product numbers by pressing  
NEXT or PRIOR and confirm with ENTER .The new parameters are valid now.  
After switching to a new product bank the machine assumes the label roll has been changed or  
that a parameter such as STOD is different and so requires an initialisation of the label position  
at the dispensing edge. This is done by pressing the FEED key after loading a new product  
bank at which time the machine will move the first detected label edge to the dispense position.  
Note: If the FEED key is not pressed after loading a new product bank the first  
detected label edge will be moved to the dispense position at the first signal from  
the product sensor!  
Note: The function FACT available in the configuration menu clears all the product  
banks.

6.2 Menu functions  
The menu functions are explained in detail here.  
Permanent test___________________________________________________DTST  
The permanent test makes a test run without using labels. In the display the numbers of  
dispense cycles is shown (see description LABC). Immediately after starting the function, the  
machine runs in a self-test. The test run works with all adjusted parameters. The test can be  
stopped by pressing the key ENTER.  
Polarity of the product sensor ______________________________________ P_S_  
The machine requires a start signal for each product to be labelled. After the start delay (STAD)  
the labelling starts. The signal is usually created by a light sensor at the conveyor. A PLC can  
also supply this signal. The light sensor supplies a signal when the light beam is interrupted by  
the product. By means of the function P_S_ it will be selected whether the leading edge or the  
trailing edge of the product should trigger the signal.  
Usually the trailing edge of a product is used. Reasons for detecting the leading edge can be:  
-
shape of product (your should avoid detecting a radius or a declined edge)  
In case of using other than the standard product sensor’s, the meaning of the display can be  
reversed. The adjustment you need you may change with the keys NEXT or PRIOR.  
Factory adjustment: LEDG  
Machine type ___________________________________________________ MACH  
The software is identical for several different machines. Choice the correct type.  
Dispensing direction ______________________________________________ MDIR  
The machine is available in a right and left-hand version. In the right hand version the product  
transport is from left to right when you look to the front of the machine. The adjustment is done  
in the factory and should not be changed.  
Factory adjustment: RIGHT  
Handling of missing label _________________________________________ MLAB  
There are several condition the dispenser is not able to dispense a product:  
y
y
y
the distance between products is too close  
an additional printer is not fast enough

With this function, you can decide how to react:  
NONE  
WARN  
ERR1  
ERR2  
Do nothing. The unlabeled product will be detected later in the line.  
Set the warning output and displays W__0. The production continued.  
Set the error output to stop the production line immediately and display E_10.  
The first unlabeled product generates the warning. Two unlabeled products in a  
sequence set the error.  
ERR3  
The error condition will be set at 3 unlabeled products.  
Automatic product speed follower_________________________APSF  
Under parameter APSF the automatic product speed follower function can be activated (ON /  
OFF). The APSF sensor is fitted to the conveyor and supplies signals that represent the speed  
of the conveyor. The installation of the sensor and the adjustment of the parameter have been  
carried out according to your application and should not be changed.  
The compensation steps for the current conveyor speed are constantly recalculated rather than  
just when the product-sensor is triggered. This means that a change in conveyor speed  
between the time that the product is detected and the time it reached the dispense position has  
no effect on labelling placement accuracy.  
There is no optimum EGRA setting. The compensation steps are calculated using the current  
EGRA setting rather than using fixed compensation step values for a predetermined EGRA  
setting and so any EGRA value works just as well.  
At slow speeds the label dispense speed matches the conveyor speed exactly regardless of the  
EGRA setting. For instance if the dispenser needs to make 1.236 steps per encoder pulse then  
at the first four encoder pulses the dispenser will make one step but will then have fallen  
4x0.236=0.944 steps behind. On the fifth encoder pulse the dispenser will make two steps and  
so be (5x0.236)-1=0.18 steps behind. The dispenser will always be less than one step behind.  
The dispenser thus always dispenses the correct amount of label in regard to the product  
movement even when the conveyor is starting from rest or coming to rest.  
Type of applicator ________________________________________________APPL  
In most cases, the label is dispensed directly onto the product. If this is not possible, an  
applicator has to be used. We offer a number of different applicators. In this function, the  
installed applicator has to be defined. You may select the applicator type you have ordered for  
your application (display shows 'ASA`,`EP`, RVEP or another applicator). In case of direct  
dispensing the function direct dispense has to be chosen:  
Display shows 'DIR'.  
The adjustment is done in the factory and should not be changed.  
RVEP (ReVerse EP) operates as an EP applicator except that once the label has been  
dispensed onto the applicator the applicator cylinder is extended to wait for the next product to  
arrive. This provides more accurate labelling than with EP applicators because variation in the  
time it takes for the cylinder to extend does not affect the labelling position.

Adjustment resetting______________________________________________FACT  
This menu point sets all parameters back to the factory values. All parameters will be reset, so  
please note all your adjustments before. When you call this function the display shows 'NO`.  
After you have left by pressing the key ENTER there is no change.  
When you change with the key NEXT to YES and press ENTER all parameters are reset to  
default values.  
Note: This function also clears all product banks.  
Interface baud rate_______________________________________________ BAUD  
With this function the baud rate of the interface will be adjusted. This is an option of the  
machine. If you do not have this option, the parameter has to be set to 'NONE` to protect the  
interface and to avoid errors. The following baud rates are adjustable: 150, 300, 600, 2400,  
4800, 9600 and 19200 baud. When calling the function FACT this parameter will be set to  
`NONE`. When the machine is delivered with the interface the baud rate is set to 9600. Select  
your baud rate by pressing the key NEXT or PRIOR . With the key ENTER the adjustment is  
stored.  
Factory adjustment: NONE  
Parity bit ________________________________________________________ PARI  
The function is only visible if a baudrate is selected. The parity bit is necessary to check the  
data transfer. In case of wrong data transfer an error message will be given. The adjustment of  
both machines has to be identical. Usually the transfer is made without parity bit.  
Possible adjustments:  
'NO`:  
Not sending or receiving a parity bit  
`EVEN`: produce a parity bit so that an equal number of `1` signals is created  
`ODD`: produce a parity bit so that an odd number of '1' signals is created.  
`0PRT`: The parity bit is always 0  
By pressing the key NEXT or PRIOR the adjustment is selected and by pressing the key  
ENTER the function is finished.  
Factory adjustment: NO  
Number of stop bits_______________________________________________ SBIT  
The function is only visible if a baudrate is selected. This parameter defines the number of stop  
bits. By pressing the key function you can select between `1BIT` or `2BIT`. By pressing the key  
ENTER this function will be left.  
Factory adjustment: 1BIT

or 8 data bit protocols.  
Factory adjustment: 8BIT  
Recycle (simulates max labels/min) ________________________________ RECY  
The Auto-recycle function, is used to determine the maximum possible cycle rate with the  
current parameter settings.  
It will cycle through applicator cycles automatically by internally generating a product-start the  
instant a cycle has been completed and displays the average cycle rate per minute in the  
display. It also operates with no applicator selected by dispensing labels at the maximum  
possible rate. The maximum labelling rate for different values of PDT can be determined using  
the RECY function without having to physically connect the printer.  
Distance sensor to dispensing edge _________________________________ DIST  
This function defines the distance between the material label sensor and the dispensing edge.  
This value is shown in steps of 0.1 mm (e.g. 0456 means 45.6 mm). The measured value can  
be adjusted by pressing the key FUNCTION.  
If the DIST value has been adjusted correctly the first leading label edge detected at  
initialisation will be moved exactly to the dispensing edge, as long as STOD is set to 0.0 (mm).  
This parameter is important for the missing label compensation. If it is not correctly adjusted a  
missing label on the material roll, will not be compensated correctly and the product will not be  
labelled.  
Value range: 10.0 .... 999.9 mm  
Label counter ___________________________________________________ LABC  
Each dispensed label increases the counter by 1. The capacity of the counter is for  
999 999 999. The total number can be seen in 3 sections, press the keys FUNCTION as  
described down below:  
Mnnn Knnn .nnn

where M represents millions  
K represents thousands  
.represents units  
On entering the "LABC" parameter the units are displayed. By using the arrow keys can then  
be used to change between the millions, thousands and units displays.  
By pressing NEXT and PRIOR at the same time the counter is set to 0. By pressing the key  
ENTER the function will be left.

7. Serial interface  
The machine has a serial interface according to the standard RS232C. Via this interface  
parameters can be adjusted. All received commands are tested for syntax and legal value  
range.  
Invalid commands and parameters are ignored. An error message is not given in this case.  
All commands received over the serial interface are tested for syntax and range; invalid  
commands and out of range parameter values are ignored. A warning message is not given in  
these cases. However in the case of framing, parity or overrun errors the warning "W__3" is  
generated.  
The commands are made up of sequences of ASCII characters. Each command starts with "#"  
and "!" followed by a 4 character code. The reception of the "#" character indicates the start of  
a new command to the machine.  
The codes are similar to the parameter names shown in the display.

8. Connections and signals  
This machine has a number of inputs to connect sensor’s and a control. Outputs are available  
for applicators, a printer and other purposes.  
8.1 Output signals  
This machine has eight outputs, which switch the output from open circuit to + 24V. The  
maximum current must not exceed 500 mA. The four signals for error messages, machine  
ready, low material and warnings are available for other machines in the process or additional  
alarm signals. For connecting an applicator three signals are available and one additional for  
the printer.  
The output signals are available at terminal connector CN33 on the main board. The wiring of  
the terminal is shown otherwise.  
8.1.1 Error and warning output  
The outputs for errors and warnings are available on the terminal CN33 and optional on the I/O  
plug. The signals are switched active (+24V) if an error or warning occurs. When the error or  
warning is erased, the signal becomes passive again.  
8.1.2 Printer output  
This machine can be connected to a printer. To use the printer the PDT parameter should be  
adjusted.  
A new label cannot be dispensed until the printer dwell time set in PDT is over.  
8.1.3 OD-Control output  
This output is switched active (+24V) if the OD-Control input is switched active during  
dispensing.  
8.1.4 Ready output  
This output shows when the machine is ready for labelling. This output is switched inactive if  
there is:  
an error message appears in the display  
the mains supply voltage has fallen below specification  
the machine requires initialisation  
in OFF condition.

8.2 Applicator modes  
The machine is able to dispense the label direct on the passing product. There is also the  
possibility to drive without any external control a wide range of applicators.  
8.2.1 Signals for direct dispense  
For direct dispensing the airstream signal can be used to control a pneumatic driven dispensing  
edge. The start of the airstream signal (= motor run signal) could be behind the start of the  
dispense motor, adjusted with the function APT3. The signal is switched inactive, when the  
label dispense has been completed. Also the stop could be adjusted with the function ASTP to  
switch inactive before or behind the dispense motor stop.

8.2.2 Control signals for the ASA applicator  
For controlling an air stream applicator the signals air- stream and blow on are necessary. The  
time period APT2 defines how long the blow on signal is active. After labelling the product and  
the time period of APT3 a new label will be dispensed on to the applicator. After that the  
machine is ready for a new labelling.  
All errors are given after 5 seconds!

8.2.3 Signals for the EP applicator  
For controlling the applicator the signals air stream, cylinder valve and blow on are necessary.  
After a product signal has occurred the labelling cylinder valve is switched active after the delay  
STAD. However if at this time the applicator is not in the home position then error message  
E__2 is generated. After the delay time APT1 the blow on valve is switched active for the time  
APT2.  
When APT2 is completed both the labelling cylinder valve and the blow on valve signals are  
switched inactive. If the control does not read the home position in the time given - 3* (APT1+  
APT2) - than the error message E__2 is generated.

8.3.1 Product sensor  
The product sensor starts the labelling. The source of the signal could be a optical sensor, a  
switch or a signal from a PLC. The time between start signal and start of dispensing (adjusted  
with POS) should be as small as possible. This means that an optical sensor should be placed  
10 to 20 mm before the dispensing edge. The minimum distance is necessary for the internal  
speed compensation.  
The machine is supplied as standard with one socket for connecting the product sensor. You  
may either use a NPN or PNP type sensor output.

8.3.3 APSF sensor  
For the APSF function (Automatic speed follower) a rotary encoder has to be installed. For  
optimum labelling accuracy the rotary encoder should be selected so that it produces one pulse  
for every 0.125 mm of product movement. The connection of the encoder should be done with  
a shielded cable. For correct operation the rise and fall time of the encoder signal should be  
1 µs.

8.4 EMI  
To protect the machines against electrical noise and to protect production of electrical noise  
you have to follow this rules:  
Rule 1  
All metallic parts must have a good and plane contact (no lacquer, aluminium oxide is an  
isolator). Use scratch washers.  
Rule 2  
Signal lines (Data- , communication- and control cable) has to separated to power cables. The  
minimum distance is 50 cm (20 cm inside a cabinet).  
Rule 3  
All signal lines should be lead in the machine or cabinet only on one side.  
Rule 4  
Unshielded cables must be twisted (both poles).  
Rule 5  
On all inductive components (relays, valves) must be directly connected a clamp circuit (diode,  
MOV).  
Rule 6  
All signal lines must be shielded. The shield must have a good earth connection on both sides.  
For the connection use metallic clamps. Don’t use a soldered wire for this connection.  
In case of different earth potential on both cable sides install parallel a cable of at minimum 10  
mm2.  
Rule 7  
The shield of analogue cable (Video etc) should be shielded only on one side. Normally there is  
no such cable with labelling machines.  
Rule 8  
Line filter has to be mounted directly on the cable entry.  
Rule 9  
Cables should not fly in the air. Lead all cables nearby metallic, grounded parts. Ground  
unused cables and wires in a cable at minimum on one side, better on both.  
Rule 10  
Cables should not be longer as necessary.

9. Errors and warnings  
The software checks during the labelling permanently, if the machine runs under normal  
operation. If labelling is not possible, the display shows a message e.g. E__0.  
If the labelling can be continued, but a problem has occurred or may occur, the display shows a  
warning e.g. W__1.  
By pressing the key ENTER the message will be erased.  
In case of an error or warning message the relevant output is switched. The signal can be used  
for interconnection with an external machine control.  
Via the serial interface the errors and warnings can be called.  
If an error cannot be erased, please call your local service technician.  
9.1 Dispenser error messages  
In case of an error message the relevant output is switched. The signal can be used for  
interconnection with an external machine control.  
STO! Power-fail message  
The message STO! appears in the display as the machine is switched off or if the mains supply  
voltage has fallen below specification.  
The message STO! (store) indicates that the machine has stored some parameters internally  
as a power fail condition was detected. The error output is switched active and the ready output  
inactive simultaneously with STO! appearing in the display.  
If the mains supply voltage only experiences a drop in level and then returns to a correct level  
then the ready output is restored to its previous condition but the message STO! will remain in  
the display to indicate that there has been a problem with the mains supply.

10.1.1 Application specification  
The labeller is designed and built for automatic applies of self-adhesive labels.  
10.1.2 APSF- Sensor Specification (Optional function)  
The resolution of the sensor should be selected in a way, that for 0.15mm product travel a  
sensor pulse will be generated. Using a different resolution gives loose in label accuracy or  
limits the highest dispensing speed.  
It is possible to use one common sensor for several dispensers. In this case the sensor is  
supplied from one machine or the several supply voltages switched parallel are separated with  
diodes.  
Supply voltage:  
Output current:  
Signal rise and fall time:  
Max frequency:  
Signal ratio:  
24 V DC  
20mA for each dispenser  
each 1µs  
20 kHz  
1:1 +- 12,5 %  
Connection:  
Only shielded cable. The shield has to be grounded on both sides.

10.2 Performance charts  
The following charts show the maximal theoretically labels per minute rate. Tolerances in  
product speed, label and product dimensions reduce the label rate. The charts are valid for  
direct dispensing (without applicator and printer). For critical applications, performance test  
should be done first. The charts are valid for software version V4.0.
