with all hints and cautions contained in these instructions, as well as in the instructions of the drive manufacturer.
The MINI-STOP is destined for the sewing industry and for being run in clean and dry rooms. It may not be put into operation
when the machine, in which it is incorporated, does not comply with all regulations and provisions. It is not allowed to use the
drive in outer humid spaces or in spaces with possible explosion risk. It is necessary to observe the hints of the manufacturer
concerning the running, attendance and maintenance. The MINI-STOP works in a safe and dependable way when there are
maintained the hints of the instructions and the purpose of the driver use. These instructions should be carefully read before
unpacking and putting the drive into operation. Before the first putting of the MINI-STOP, its accessories and supplements into
operation, be sure in being acquainted with the hints concerning the assembly, attendance, running and maintenance. All
activities connected with the drive may be carried out only when observing the respective regulations and when respecting the
given safety rules descreibed in the following parts of the indstructions. All persons concerned must be acquainted with these
safety warnings. The inobservance of these hints may cause injuries of persons, damage of objects or breakdowns or damage of
the drive.
It is necessary to observe the regulations concerning accidents, safety and skilled labour being in force in the given country.
The MINI-STOP may be installed and put into operation only by qualified persons. This will reduce to a minimum the consequences
of breakdowns with the possible health injury of persons.
Operations carried out on the machine or on its parts under high voltage are not allowed. Exceptions thereof are regulated by the
EN 500 standard.
Before removing guards, assembling additional devices or accessories, e.g. sensors of the pedal position, photocell etc., the
drive must be disconnected from the mains and the drive must be put ito its idle condition. The operating box may be oppened
only after having run 0 minutes! wing to the risk of burning, fire, electric chock or injury, any reconstructions or eventual
modifications of the MINI-STOP are prohibited. During the running thereof, its guards or protective devices may not be removed.
Before leaving the work place, the mains switch must be out into the OFF condition. When the drive is out of use for some time,
the mains plug is to be disconnected from the mains and the drive must be secured against an accidental switching on.
In the event of having connected additional devices or operational means to the drive, these may be fed only with low voltage
from a safety transformer.
Never operate the drive when the air vents there of are clogged. Be sure in avoiding the presence of dust or fibres therein. Do not
insert and avoid falling of any object, e.g. needles, into these vents. Do not use MINI-STOP when working with aerosols and
sprays or with oxygen. The cautions mentioned in the following parts serve for ensuring further safety.

Setting by means of parameters
Drive memory contains the parameters which enables sewing
system tuning. These parameters have exact meaning and
they are divided into 3 levels. Further parameters which are
available only for operation will be quoted. Each parameter
has its (sequence) number and value.
General procedure by changing parameters of operation level:
-switch the main switch on or finish the seam by pressing the
treadle fully backwards down
-press pushbutton P on the panel V 820
-on the display there is no data shown
-by depressing the pushbutton E several times, set the
required parameter (without having displayed the parameter
number)
-you can change the value using pushbuttons + or -
-by depressing the pushbutton E you will pass in the given
sequence to the following parameter
-by depressing the pushbutton P down you will leave the
mode of changing parameters
ote: .For permanent memory storing of changed pa-
rameter, it is necessary to press treadle forwards
down after changing of parameters.
2.Mode of changing parameters is possible only af-
ter finishing of the seam.
Procedure of changing parameters of the higher level
-depress the pushbutton P on panel and switch on thereafter
the main switch
-on the display there will appear C 0000, the st digit flashes
-using pushbuton 0 ÷ 9 set C 3112 on the display (code
number for possible changing of all drive parameters)
-depress the pushbutton E, on the display will appear F 200
(parameter number 200)
-using pushbutton 0 ÷ 9, set the required parameter number
and depress the pushbutton E
-using pushbutton +, - , set the required parameter value
-depress the pushbutton E (there will appear further param-
eter number in the given sequence) or P (return to the given
sewing mode)
-the termination of changes is to be done in depressing the
pushbutton P (return to the sewing mode)
