to eliminate rotating members inside the synchronizer, especially on fast machines.

Just fit the synchronizer to the shaft. No mechanical adjustment is required, as the setting of the “0” reference and the stopping
positions of the machine will be accomplished afterwards in the configuration phase (see Timing paragraph page 11).

(only one detection per revolution is necessary).
The proximity sensor must not be further than 1,5 mm (1/16 in) from the hand-wheel.

When the MT800 console is not available, the motor being installed must already be fully set-up, so that only the “0” reference
position must be defined. This can be achieved through the following procedure:

SOCKET PANELS
Easily interchangeable, their aim is to adapt Argo to the different types of connectors on sewing machines of different brands

proper wiring harnesses (available as accessories).

nd to special connectors, it is advised to use the panels of the CZ class (CZ0, CZ1, CZ2, CZ3,

Choose them when Sewing Programs and photocell are not used.
Three outputs are available on the CZ0 panel: presser foot lifter, thread trimmer (or chain suction on over-lock machines), threa
wiper (or tension release, or needle cooling (running signal)). One input for the emergency stop and one duplicate for the
synchronizer are also available besides the standard ones for the synchronizer, the console and the keyboard.
Five outputs are available on the CZ1 panel: presser foot lifter, thread trimmer (or chain suction on over-lock machines), tensio
release (or needle cooling (running signal)), thread wiper, reverse feed (back-tack) or upper thread trimmer. Besides the standard
inputs (synchronizer, console and keyboard), one input is available for the emergency stop, one duplicate for manual back-tack,
one duplicate for the synchronizer and one input for the safety switch to control the release of the thread trimmer (fitted to many
chain-stitch machines). The CZ1 panel, used with the MT600 console, allows the execution of programmed back-tacks.

CZ2 SOCKET PANEL
It allows a more comprehensive use of Argo: Sewing Programs can be written and executed by using the MT800 console (using a
photocell if needed); production data can be collected. Sewing Programs can be transferred to or copied from other sewing
machines or personal computers.
Five outputs are available on the CZ2 panel: presser foot lifter, thread trimmer (or chain suction on over-lock machines), tensio
release (or needle cooling (running signal)), thread wiper, reverse feed (back-tack) or upper thread trimmer. Besides the standard
inputs (synchronizer, console, keyboard, photocell and remote treadle), four inputs are available: for the emergency stop, for the
safety switch to control the release of the thread trimmer (fitted to many chain-stitch machines), one duplicate for the synchronizer,
one duplicate for the photocell and one duplicate for manual back-tack.

CZ3 AND CZ4 SOCKET PANELS
They have been developed to connect and control external devices used in automatic sewing systems (besides all possible devices
available on the machine).
Besides the features already available on the CZ2 panel, they offer the possibility of connecting up to twelve programmable
out
puts (to be divided among external devices and those on the machine) and nine inputs, one of which is analog (it reads levels
between 0 and 5 volts). They integrate the five standard inputs (remote control treadle, photocell, keyboard, synchronizer, safety
switch).
On the CZ3 panel only eight outputs are available, three of which to be assigned to external devices.
On the CZ4 panel there are twelve outputs that can be freel
y assigned to machine devices or external ones.

This socket panel has the same features of CZ4 socket panel plus it has the possibility to be conn ected to one or more external

THE MT800 CONSOLE
This console is the most powerful instrument to access the functions available with ARGO; through it, it is possible to intervene at
any level and on each aspect of the application. It is used by installers, maintenance personnel and by users.
Through the use of the MT800 console, installers define their application precisely and in details, adjust the parameters of the

INSTALLATION SETUP
On the MT800 programming console, at every position of the cursor corresponds a message displayed in the bottom line that will
help you through the programming. Basically, to program Argo, you simply follow the instruction s in the messag e line until the
motor is fully configured.
There are three diffe rent ways to

TRANSFER OF THE SETUP THROUGH THE KK195 MEMORY
By means of a KK195 memory chip it is possible to copy the configuration from an already installed machine and transfer it to a
machine of the same type. When required, at this moment it is also possible to transfer all the Sewing Programs.
To transfer a machine configuration from an external KK195 memory chip to the motor:

since it left the factory; the total time the motor has been running (in hours and minutes) since it left the factory; percentage of
running time versus motor-on time. The column in the middle shows respectively: the total time the motor h a s been turned on (in
