1. CHARACTERISTICS

Stop motion control device equipped with the most modern electronics in an industrial metalcase:

- recognizes immediately any thread breakage and loose threads;- signals these defects acoustically and optically;- provides for the machine stop;- signals the recognized faults even with stopped machine.

The ARGUS disposes moreover of some helpful finesses:

- Quartz clock continuing its function even with switched off device, with display of the hour anddate.

- Speed counter (revolutions per minute).- Five stitch counters.- Five revolution counters.- Switch clock for the machine cutoff.- Code protection.- System for the production data collection.

The principle of function of the ARGUS:

Each thread is controlled by an electromechanical contact (switch bar). In case of thread breakage,this one makes contact over the machine mass (contact rail).

At the embroidery machine, all the threads are tensed only during a short moment of the stitchingcycle. The fault interrogation must take place exactly during this period. ARGUS seizes this momentby means of an electronic contact transmitter (sensor).

Should a thread breakage occur, it is evaluated through the central electronics (CONTROLLER)and signalled acoustically and optically by means of the indicating panel (INDICATOR). Eachmachine sector disposes of its own indicating section allowing a quick localization and discovery ofthe broken thread.

ARGUS Page 5


2. PARTS OF THE UNIT

A complete stop motion control unit must be composed of the following equipment:

- Electromechanical contact (contact rail with switch bars):

Each thread is electromechanically controlled by a switch bar.

- Sensor/s:

The sensors transmit the most important data of the embroidery machine to the ARGUS Control-ler. The electronic contact transmitters 1 and 2 must be NPN make contacts. The debouncingtime of sensor 3 to 7 amounts to appro. 5 sec.

For the stop motion function there is required the sensor 1 which is controlled by the top andbottom needle track shaft and which determines the moment of the fault interrogation. Sensor 2is required to compute the card meters and embroidery percentages. Electronic contacttransmitters are usually used for sensor 1 and 2 (needle and drive shaft). No particular demandswith regard to the speed are made on the sensors 3 to 7. Electrical contact transmitters or limitswitches with gold contacts are admissible.

- ARGUS Indicator:

Indicating panel for the optical (LED) and acoustic (loudspeaker) fault signalling.

- ARGUS Controller:

Central device with input keyboard, display elements, power supply and supply terminals.

- Evaluation program:

A computer to collect, read and evaluate the data provided by the ARGUS Controller (from up to30 embroidery machines).


ARGUS Page 6

3. DISPLAY FUNCTIONS

A LED arrow (11) indicates the set function. The desired function can be selected by means of thekey (Ù) (up) or (Ú) (down). The corresponding data appear on the display.

The variable data of the ARGUS (f.ex. hour, date, loudness etc.) are input in accordance with thefollowing scheme:

Adjustment:

Selection of functions: Push the key (Ú) or (Ù). The function indicator isshifted upwards or downwards and the displaychanges.

Modification of the setting: Push the (ENTER) key, the flashing place can bechanged.

Increase the number or ON: by means of the (+) key

Reduce the number or OFF: by means of the (-) key

Selection of next number, counter or test: by means of the key () (right)

Memorize the setting: push the ENTER key.

Setting error: the display flashes and indicates ERROR. The inputcan be repeated.

Input over the computer:

Should the ARGUS be linked within a data network with a central PC, all important settings can beinput over the PC as well.

Code protection:

All the functions can be protected by means of a code against any unintentional or unauthorizedvariation. The input of the code is described in item 3.7. (page 9).

Forgotten code: Should the functions be protected by means of a code and should this code notbe known, then this is equivalent to the loss of a key. Help will be given to youby the company ALGE or by the ALGE agent.Should there be inserted a central PC, an intervention can be made through the PC.

Protection of the settings:

All the settings are preserved even with switched-off ARGUS.

ARGUS Page 7


3.1. FUNCTION 1: Time of day and RPM

Time of day:

The daily hour is indicated in hours and minutes. The setting is required at putting into service aswell as at change between summertime and wintertime. The integrated quartz clock is batterybuffered and maintains its function even with switched-off ARGUS (see also function 12, page 11).With the key "" you can change the starting time form shift 1, 2, 3, and 4.

RPM:

The speed is indicated in rpm. The pulses required for the measurement are provided by the sensor2 (drive shaft). Should the sensor 2 not exist, the ARGUS recognizes its absence and gets thepulses from sensor 1 (needle shaft). This means: no stitches, no display.

Start of a shift:

Display function and changing see point 3.1. "Time of day".

3.2. FUNCTION 2: Date

The display shows: Year, month and day (e.g. 93-07-11). The date is provided by the internalquartz clock (see also function 12, page 11).

3.3. FUNCTION 3: Sound volume (L) and pitch (H)

Sound volume:

Loudness from 0 to 5, with 0 meaning the switched-off condition and 5 the maximum loudness.

Basic setting: 3Setting range: 0 to 5

Pitch:

The tone height can be changed in order to differentiate the machines. There is available a rangefrom stage 1 (deepest tone) till stage 9 (highest tone).

Basic setting: 1Setting range: 1 to 9


ARGUS Page 8

3.4. FUNCTION 4: Fault stop and stop delay

Fault stop:Indicates the number of faults to precede a machine stoppage. If the fault stoppage 0 is input, thestop function is not activated.Basic setting: 10Setting range: 0 to 99

Stop delay:The command stop the embroidery machine (stop relay) is released only after the stoppage delay.The stoppage delay of modern embroidery machines is 0. In the event of older types without ma-chine brake it must be set in a way to let the needles have already left the fabric.Basic setting: 0Setting range: 0 to 99 (corresponding to 0 to 792 ms)

3.5. FUNCTION 5: Inquiry time and error suppression

Inquiry time:

This is the time, that the thread contact must be without contact in order to have a error free inquirytime. With the impulse of senor 1 it starts the check time t

P (fix duration of 80 ms). During this time it

makes the inquiry.

Adjustment of sensor 1 see point 9.2.

Example: tA = 18 ms (adjusting 6)

Evolution: t1

= 5 ms = decision "still error"t

2= 25 ms = decision "no error"

t3 = 10 ms = no effect for decision

ARGUS Page 9


As longer the inquiry time is, as easier it is to detect not clear errors like loose threads. On the otherhand there is a very short time for the tensed threads when the machine is running fast (high rpm).

Correct setting:Simulate a error. If the signalisation (LED indicator or speaker) is rytmic with every stitch, it meansthat the inquiry time is correct adjusted. If this is not the case increase the inquiry time until the LEDgroup shows the error regular.

Basic setting: 4 (= 9 ms)Setting range: 1 (= 3 ms) 3 (= 6 ms) 5 (= 12 ms)

2 (= 4 ms) 4 (= 9 ms) 6 (= 18 ms)

Error suppression:

Indicates how many of the recognized faults are suppressed before there takes place an acoustic(loudspeaker) or optical (indicator) warning. The setting is made as at function 1.Basic setting: 2Setting range: 0 to 4

Note: Long stitches, big bore holes and repeat changes can release fault messages. In order tosuppress them, the fault suppression can be set as follows:

0 ............. textured yarn and macrame1 ............. high speed2 ............. standard3 ............. colour and repeat change4 ............. silks and tulle fabrics

Attention: The shuttle display might go lost in case of a high setting !

3.6. FUNCTION 6: Sector selection

The sectors are indicated on the display (2). Those sectors where no embroidery takes place canbe switched off.The sectors which are not supervised due to the selected Indicator variant are marked by means ofcentre lines.Basic setting: all sectors ON

3.7. FUNCTION 7: Code

The ARGUS is supplied by ALGE with deactivated code protection (C=000000). In order to protect theinput values against any unauthorized manipulation, any code composed of 6 digits can be input.Basic setting: C=000000 (code protection deactivated)Setting range: C=000000 until C=999999.


ARGUS Page 10

3.8. FUNCTION 8: Switch-off time and machine number

Switch-off time: A switch-off time can be input in order to have the machine switched off at aspecific daytime (hours and minutes). If the switch-off time 0.00 is input, nomachine stoppage takes place at a given time.

Machine number: Should the ARGUS be part of a data network, each one receives its own numberbetween 1 and 30.

Basic setting: 0 (no communication with the PC)Setting range: 0 to 30

3.9. FUNCTION 9: Design number

For the statistic evaluation by the PC, a number (max. 8 digits) can be assigned to the embroidery design.

3.10. FUNCTION 10: Stitch counter

Sensor 1 (needle shaft) supplies the pulses to be counted.The 1st counter is a summation counter (8 digits) without reset possibility with its content beingmemorized even after having switched off the ARGUS.The counters 2,3,4 and 5 (6 digits) are assigned to the corresponding shifts. The counter content ismemorized only until a new shift is selected.The different shifts or the summation counter can be selected by means of the key.

3.11. FUNCTION 11: Revolution counter

This function is available only if sensor 2 (drive shaft) is existing.The 1st counter is a summation counter of 8 digits without reset possibility, with its content beingmemorized even after having switched off the ARGUS.The counters 2,3,4 and 5 (6 digits) are assigned to the corresponding shifts. The counter content ispreserved only until a new shift is selected.The different shifts or the summation counter can be selected by means of the key.

4. PRODUCTION DATA

4.1. Machine statistics:

The machine standstill reasons are set by means of the keyboard of the ARGUS (A - F) or auto-matically detected by the sensors (G - K). The machine standstill duration is registered by theARGUS and provided with the date and hour.

The standstill reason A must always be used for mounting of the fabric, the remaining reasons (B - F)are optionally available.

Together with the standstill reason A or in the event of a shift or design change, there is memorized,besides the time, also the sum of the stitches and revolutions.

A number of revolutions of less than 40 rpm is considered as machine standstill.

The data are preserved even after having switched off the ARGUS. For establishing any machinestatistics, these data can be transmitted over a serial interface (RS 485) to a central PC for evaluation.

4.2. Input of shifts:

In order to be able to assign the resulting data to the right working shift, this one must be selected withthe shift start.

Selection of the shift by key (1) to (4) (red dot flashes)Memorizing of the shift by (QUIT.) key (red dot flashes continuously.

4.3. Input of standstill reasons:

The standstill reasons can be input only if the machine is not running.

The keys A to F are used for the input of the standstill reasons. The key A must always be used formounting of the fabric, the remaining reasons (B - F) are optionally available.

Input of the standstill reason:- Input of the standstill reason (key A to F) (with the possibility to input several reasons simultaneously).- LED of the selected standstill reason flashes.- Memorize the standstill reason by means of (QUIT.) key.- LED of the selected standstill reason lights up.

Cancellation of the selected standstill reasons:- Together with the machine start, all the standstill reasons are automatically cancelled.

Cancellation of the standstill reason before the machine continues to run (manually):- Push the key of the standstill reason to be cancelled.

The LED must light already. Several standstill reasons can be cancelled simultaneously.- The LED of the selected standstill reason flashes.- Memorize the standstill reason end by means of the (QUIT.) key.- The LED of the selected standstill reason is extinguished.

Sector selection: Setting: all sectors ONInquiry time: Setting: 4 (details: see page 8, item 3.5.)Error suppression: Setting: 2 (details: see page 9, item 3.5.)Fault stop: Setting: 0Stop delay: Setting: 0sound volume: Setting: 1

The setting of the remaining values has no influence on the basic functions of the ARGUS as stopmotion device.

9.2. Setting of sensor 1:

Sensor 1 is an electronic contact transmitter (NPN, Open Collector) for release of the switch bars,inquiry and registration of the stitches. The switch ring is preferably mounted at the top needle shaft.The distance between the front side of the contact transmitter and of the metal switch ring is notallowed to exceed 1 mm.

Fine setting: In the absence of a thread breakage, the LED groups must be dark if the machine isrunning. Otherwise, the switch ring must be adjusted in small steps until no more fault signallingtakes place.

Important: In the daily work in an embroidery enterprise the eccentric adjustments are very oftenadapted to the merchandise without considering the switching point of sensor 1.The result: A bad function or failure of the stop motion control unit.

9.3. Setting of sensor 2:

Sensor 2 is an electronic contact transmitter for registration of the total revolutions. The timing of theswitching point is unimportant. The distance between the front side of the contact transmitter and ofthe metal switch ring is not allowed to exceed 1 mm.

9.4. Advises concerning the switch bar,inquiry time and fault suppression:

- The higher the speed of a machine, the greater is the risk of mechanic vibrations. In the event ofthread breakage, these vibrations prevent the switch bar from having a good contact, this meansthat it is continuously thrown up a bit. Examinations with the oscilloscope at difficult machineshave shown that due to extreme vibrations quite no more fault signals are available. This meansthat setting a long time of inquiry increases the security of the inquiry. The quicker a machineruns, the shorter is the time of the tensed threads. This means: Do not select a maximumsetting, but an optimum setting.

- A further effect prevents the troublefree function of the stop motion device: If the switch bar issharply thrown up shortly before the fault inquiry takes place, it happenssometimes that despite the thread tension its energy is sufficient to give a short contact. Practi-cally this results in a restless signalling with the displays shortly lighting up even in the absenceof any fault. ARGUS offers the possibility to suppress these malfunctions (high fault suppres-sion), but as shuttle faults are appearing sporadically, these are suppressed as well. A repair isensured only by calming the switch bars by means of a good thread guidance and switch barswith limited lifting.

- Moreover a regular care of the contact bars is necessary in order to prevent high transitionresistance and shunts.

Important: What is omitted in the range of the switch bar cannot be made good even by the mostrefined electronics.

10. MAINTENANCE

Only the switch bars and contact rails require a certain degreeof maintenance.

- Weekly: Blow out the switch bars and contact rails by means of compressed air.

- In case of need: A light oiling of the switch bar pivot with a light machine oil.

- In case of need (after 10 years at the earliest):Exchange of the TK-RAM (with integrated battery and clock) if after havingswitched on the supply voltage the clock shows zero.(Exchange: see page 33, point 12).

11. TROUBLE SHOOTING

Malfunctions of the ARGUS stop motion control unit will be very rare if the following preconditions arefulfilled:

- Execution of the maintenance work in regular intervals as prescribed.

- Correct setting of the Controller and sensor 1.

On the basis of long years of observation on former stop motion control units, malfunctions shouldappear as follows:

40 % switch bars35 % wrong setting of sensor 1 5 % wrong setting of the inquiry time 5 % wrong setting of other functions

10 % installation 5 % ARGUS Controller and Indicator

11.1. Some causes of gross faults of the unit:

- Controller display and green Indicator LEDs do not light:

Possible causes:o No voltage at Controller connecting terminalso Line fuse F4 in the Controller is defectiveo Secondary fuse F5 in the Controller is defective

- The green LEDs at the Indicator do not light, the Controller display is O.K.:

Possible causes:o The numbered cable from the Controller to the Indicator is interrupted at wire 1 or 5.o The mentioned cable is connected incorrectly.

- The Controller display does not light, the green LEDs at the Indicator do light:

Possible causes:o The 14-pole belt cable of the terminal print is not plugged at the main print.o The 40-pole belt cable of the terminal print is not plugged at the main print.

- The keys do not function correctly:

Possible causes:o The belt cable of the keyboard is not plugged at the main print or plugged out-of-line.

11.2. Some causes of hidden faults:

Too many fault messages:

- Sensor 1 is incorrectly set.- The switch bars are badly aligned.- Bad needles- Bad shuttles- Insufficient thread braking- Long stitches- Insufficient tension (silk)- Distorsed threads- Soiling- Sector cable has short to ground- Fault suppression too low (see page 9)- Inquiry time too high (see page 8)

Insufficient fault messages:

- Too strong machine vibration- Soiling- Tottering contacts at the contact point of a

sector cable- Interrupted sector cable- Tottering contact at bonding clip- Fault suppression too high (see page 9)- Inquiry time too low (see page 8)- Indicator variant wrongly set- Sector selection wrongly set- Axle of switch bars need to be oiled

11.3. Test with regard to reduced insulating resistance of the bars:

By pushing the (T) key, the sensibility of the ARGUS is increased by the factor 2 for the duration of 30seconds. During these 30 seconds, the key (built-in LED) is lighting. Should the rail be soiled, i.e. anelectrically conducting dirt layer has formed between bar pivot and contact rail (machine mass), therespective sectors will show a fault. Should there exist between bar pivot and bar or between bar andrail a layer which is electrically non-conducting, this fact cannot be recognized by the ARGUS.

The test can be interrupted by means of pushing again the (T) key.

11.4. Trouble shooting by means of the test program:

The test program is started as described on page 12, item 3.13.

1. Test PrOG: Indicates the program version, without giving evidence however on thegood function.

2. Test TON-TEST: No song is emitted.

Possible causes:o The numbered cable from the Controller to the Indicator is interrupted at wire 6 or 7.o The above cable is connected incorrectly.o The loudspeaker is defective.

3. Test LED-TEST: Not all of the display segments or not all of the LEDs are lighting.

Possible causes:

15.Test RESET: Should the reset not be executed automatically, the main print is defective

11.5. Function check of sensor 3 to 7:

A closed contact is signalled by the corresponding LED at the Controller. The debouncing timeamounts to appr. 5 seconds.

11.6. Function check of the switch bars (divided into sectors):

With running machine, simulate an error in the desired sector. The corresponding LED group mustrespond by flashing.

11.7. Auxiliary Indicator at the Controller:

For the purpose of locating the defects or in the event of a failure of the Indicator print, the displaySECTOR provides an independent fault message. Together with the acoustic fault message anemergency service is still possible.

11.8. Indicator does not display:

Iti is possible that the indicator has 380 V instead of 220 V.
