COUNTING SYSTEM
The rewind machine incorporates a bi-directional dual
preset counter. This permits the operator to set sepa-
rate deceleration (Preset A) and stop (Preset B) points.
The counting system can be operated in either the pho-
toelectric counting mode or the length counting mode.
In the length counting mode, the counter is driven by
means of two magnetically operated proximity switches
located in the table top beneath the counter drive roll.
A magnet in the lower end of the counter drive roll op-
erates the proximity switches. The combined signals
from each proximity switch allow the counter to auto-
matically count up or down depending on the direction
of rotation of the counter drive roll. This is primarily
used when pulling defective material backwards off the
rewind roll. Be sure the web is held against the counter
drive roll when it is pulled backwards. When counting
photoelectrically, the operator must place the COUNT
UP/COUNT DOWN switch in the “COUNT DOWN” posi-
tion before pulling the labels backwards. The switch
must be returned to the “COUNT UP” position before
moving the labels forward again. The MANUALLY IN-
CREMENT COUNTER pushbutton will illuminate when
the COUNT UP/COUNT DOWN switch is in the “COUNT
DOWN” position in order to remind the operator that
the counter is set for counting backwards and that the
switch must be placed in the “COUNT UP” position be-
fore resuming operation.
PROGRAMMING DECELERATION AND STOP
POINTS
To set the final count, press the PRE B button on the
counter once. In approximately two seconds the current
value will be displayed. To change the value, simply
press the button under the digit that you wish to
change. Each time the button is pressed, the digit will
increment by one. When the desired value has been set,
push ENTER once to store the value into memory. To set
the count at which you wish the machine to go into the
deceleration mode, push PRE A and follow the same
procedure as described above. If you do not wish to
have a deceleration period, simply set the final count
Preset B as normal and set Preset A to any number
larger than Preset B.
NOTE
All Rewind Machines are equipped with an electronic
programmable counter. This counter is quite sophisti-
cated and is capable of performing certain functions not
applicable to our usage. While programming the coun-
ter, you will notice “LoC” will appear. This is to let you
know the manufacturer has programmed the counter to
deny access to the functions not required for our
application.
While it is possible for the counter program to become
scrambled (possibly due to line noise, electrical storms,
etc.), it is important to note that this will disable the
counter from performing as it should. In order to cor-
rect the situation, the counter will need to be re-pro-
grammed. For your convenience, we have provided re-
programming instructions located in the final section of
this manual in the event that this occurs
DETERMINING PRESET B (STOP POINT)
LENGTH MODE COUNTING
The counter registers one count per ten inches of web
travel when using the standard ten inch circumference
counter drive roll. This makes it easy to calculate the
appropriate number to enter into the counter in order
to wind a roll of a given number of labels. The number is
calculated as follows:
𝐂𝐨𝐮𝐧𝐭 =
(𝑵𝒐. 𝒐𝒇 𝒅𝒆𝒔𝒊𝒓𝒆𝒅 𝒍𝒂𝒃𝒆𝒍𝒔)(𝒓𝒆𝒑𝒆𝒂𝒕 𝒍𝒆𝒏𝒈𝒕𝒉)
𝟏𝟎
EXAMPLE: To wind a roll of 1000 labels of 3 inch repeat
length, the number 300 would be entered as the final
count (Preset B).
𝐂𝐨𝐮𝐧𝐭 =
(𝟏𝟎𝟎𝟎)(𝟑)
𝟏𝟎
= 𝟑𝟎𝟎
LABEL COUNTING MODE
Every label is counted as it passes through the scanner.
No calculations are required. Set Preset B to the desired
total label count.
DETERMINING PRESET A (DECELERATION COUNT
SETTING)
The point at which deceleration should begin depends
on many factors (rewind speed, finished roll diameter,
etc.). Therefore you probably will need to test your de-
celeration count setting each time you rewind a new
type of label. The desired technique is to have the ma-
chine stop shortly after it decelerates fully and has sta-
bilized at the lower speed. For the first attempt try a
setting that is 150 counts less than the final count. This
means that the counter will begin to decelerate the
machine 150 counts (15M) before the end of the roll.
EXAMPLE: If the final count (Preset B) is 750, then the
deceleration count (Preset A) should be set at 600.
