1. CHARACTERISTICS
Stop motion control device equipped with the most modern electronics in an industrial metal
case:
- 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 and
date.
- 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 stitching
cycle. The fault interrogation must take place exactly during this period. ARGUS seizes this moment
by 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). Each
machine sector disposes of its own indicating section allowing a quick localization and discovery of
the broken thread.

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 debouncing
time 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 and
bottom needle track shaft and which determines the moment of the fault interrogation. Sensor 2
is required to compute the card meters and embroidery percentages. Electronic contact
transmitters are usually used for sensor 1 and 2 (needle and drive shaft). No particular demands
with regard to the speed are made on the sensors 3 to 7. Electrical contact transmitters or limit
switches 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 to
30 embroidery machines).

3. DISPLAY FUNCTIONS
A LED arrow (11) indicates the set function. The desired function can be selected by means of the
key ((cid:217)) (up) or ((cid:218)) (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 the
following scheme:
Adjustment:
Selection of functions: Push the key ((cid:218)) or ((cid:217)). The function indicator is
shifted upwards or downwards and the display
changes.
Modification of the setting: Push the (ENTER) key, the flashing place can be
changed.
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 (<) (left) or (>) (right)
Memorize the setting: push the ENTER key.
Setting error: the display flashes and indicates (cid:147)ERROR(cid:148). The input
can be repeated.
Input over the computer:
Should the ARGUS be linked within a data network with a central PC, all important settings can be
input over the PC as well.
Code protection:
All the functions can be protected by means of a code against any unintentional or unauthorized
variation. 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 not
be known, then this is equivalent to the loss of a key. Help will be given to you
by 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.

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 as
well as at change between summertime and wintertime. The integrated quartz clock is battery
buffered and maintains its function even with switched-off ARGUS (see also function 12, page 11).
With the key "<" and ">" 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 sensor
2 (drive shaft). Should the sensor 2 not exist, the ARGUS recognizes its absence and gets the
pulses 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 internal
quartz 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: 3
Setting range: 0 to 5
Pitch:
The tone height can be changed in order to differentiate the machines. There is available a range
from stage 1 (deepest tone) till stage 9 (highest tone).
Basic setting: 1
Setting range: 1 to 9

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, the
stop function is not activated.
Basic setting: 10
Setting range: 0 to 99
Stop delay:
The command (cid:147)stop the embroidery machine(cid:148) (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: 0
Setting 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 inquiry
time. With the impulse of senor 1 it starts the check time t (fix duration of 80 ms). During this time it
P
makes the inquiry.
Adjustment of sensor 1 see point 9.2.
Example: t = 18 ms (adjusting 6)
A
Evolution: t = 5 ms = decision "still error"
1
t = 25 ms = decision "no error"
2
t = 10 ms = no effect for decision

Page 9
As longer the inquiry time is, as easier it is to detect not clear errors like loose threads. On the other
hand 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 means
that the inquiry time is correct adjusted. If this is not the case increase the inquiry time until the LED
group 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: 2
Setting range: 0 to 4
Note: Long stitches, big bore holes and repeat changes can release fault messages. In order to
suppress them, the fault suppression can be set as follows:
0.............textured yarn and macrame
1.............high speed
2.............standard
3.............colour and repeat change
4.............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 can
be switched off.
The sectors which are not supervised due to the selected Indicator variant are marked by means of
centre 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 the
input 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.

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 a
specific daytime (hours and minutes). If the switch-off time 0.00 is input, no
machine stoppage takes place at a given time.
Machine number: Should the ARGUS be part of a data network, each one receives its own number
between 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 being
memorized 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 is
memorized only until a new shift is selected.
The different shifts or the summation counter can be selected by means of the (cid:147)<(cid:147) and (cid:147)>(cid:148) 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 being
memorized 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 is
preserved only until a new shift is selected.
The different shifts or the summation counter can be selected by means of the (cid:147)<(cid:147) and (cid:147)>(cid:148) key.
3.12. FUNCTION 12: Special functions
1. Call.L: Volume of Call-function
2. Call.D: Duration of Call-function
3. Batt: Switch ON/OFF the clock battery
4. Ind.Set: Setting of the Indicator variants
5. Buf.: Erase memory
6. Full: Warning "memory 90% full" on or off
The input proceedings are a little bit different from the usual ones: After having pushed the (ENTER) key,
the function (cid:147)CALL(cid:148) can be switched on or off by means of the (+) and (-) key. The next special function
is reached by pushing the (>) key.
