3.2.17 Control, Lot control
Entry:
Lot...; Control...
Lot change control functions only D if the machine is switched ON;
D if the section lock* is not activated on any of the winding units; and
The control is structured in such fashion that sensible dia-logs only can be called in any lot status.
For documentation of each change of lot status an entry is made in the message listing (Entry: Data display...; Mes-sages...).
Prior to entries be sure the correct group had been selected!
Prior to lot start, double-check, and modify if re-quired, all entries on the Informator, and all settings on the machine!

Selection of the group/lot.Note:
Further information related to ”Lot, Group memory”.
Lot name
Customer’s description of the selected group/lot.
Lot No.
Customer-established code of the selected group/lot.
Winding unit range
This entry influences the currently running lot, pro-duction losses will occur in case of false entries.
Range of winding units to be processing the group selected in menu ”Lot...; Preparation..” with the defined values.
This range can be changed, i.e. increased or reduced, while the lot is being processed (ref. to next page).

Change of winding unit range
This entry influences the currently running lot, pro-duction losses will occur in case of false entries.
The working range for the lot can be changed, i.e. in-creased or reduced, while the lot is being processed.
Only an increase or reduction of the range is possible:
D Range increase
The newly defined winding units must not belong to an other lot (Group in production or in lot change).
Enter the new (enlarged) range under
➀
.With a time delay the new winding units are incorpo-rated in the winding unit range.
D Range reduction
Initially execute the entry under “Reduce”
➁
.Enter the new (reduced) winding unit range under
➀
.After the entry of “Reduce: IMMEDIATE”: All removed winding units will react as described under ”Instant (Im-mediate) lot end <>”.
After the entry of “Reduce FULL PACKAGES”: All re-moved winding units will react as described under “Lot end with full packages <>”.
During the time of change menu items

are displayed.The display may appear after a delay.

Status
Status of the selected group/lot:
DEFINED = Ready for production PRODUCTION = Lot in production LOT CHANGE = Status during lot change.
No. of packages until lot end
This entry influences the currently running lot, pro-duction losses will occur in case of false entries.
Entry of No. of packages to be produced until automatic lot end is initiated:
D This entry is valid instantly, and it can be made at any time while a lot is in production.
D Entry 0 = unlimited, i.e. this lot is to be composed of an indefinite No. of packages.
D When increasing the No., e.g., from 500 to 750 pack-ages, packages already produced are counted-in.
D When changing the No., e.g., from 0 (indefinite) to 500 packages, packages already produced are not counted-in.
➀
Display: No. of packages already produced.At the approach of lot end the winding units of the group stop, one-by-one, will full packages, similar to ”Lot end with full packages”.
In this status, when changing to ”0”, production is restored on all winding units. Winding units already stopped wait for manual restart.

Lot start <>
After the user has completed
D entry of the lot parameters, according to lot records, into the group memory (memories), or
D copying of the parameters from an other group, or D copying from a PC-Card,
the lot can be started:
D Select the group memory ¡ ... ¥ to be started.
D Define the range of winding units to be producing using the parameters of the group (→ previous page ”Winding unit range”).
D Actuate key ”Lot start <>“ and then ”O.K.”.
Prior to lot start:
D The Informator transmits the data to the winding units, to enable them to produce using the described values.
D The lot status changes from ”DEFINED” to ”PRODUC-TION”.
D The winding units perform one cycle, in order to cor-rectly place the lower end.
D If no upper end is available, the winding units, with yel-low light ON, wait for manual start-up.
D Production can begin.

Immediate lot end <>
This entry influences the currently running lot, pro-duction losses will occur in case of false entries.
D The staus of the group/lot changes to ”Lot change” (LOT CHANGE).
D Production of this lot is aborted instantly, the winding units are vacated.
D The winding units assume ”Yellow light flashing” mode (the packages are of inferior quality, because neither yarn length nor package diameter is completed), they stop with all yarn ends cut.
D After (manual) package doffing the winding units are locked and will not start again.
D When all packages are doffed the lot is accounted for au-tomatically.
D The group/lot changes to status ”Defined”.
D If ”WITH” (→ 3.5.15) had been entered in lot change re-port, print-out of the lot change report takes place.
Lot end with full packages <>
This entry influences the currently running lot, pro-duction losses will occur in case of false entries.
D The status of the group/lot changes to lot change with full packages (LOT CHANGE).
D All winding units of the group assume lot change mode, and countinue winding until the next doffing cycle is re-quired; i.e., on each winding unit the package being wound is completed.
D When the packages is full, each winding unit stops, with yellow lights ON.
D The doffer doffs the package, yet fails to place an empty cone/sleeve into the cradle.
With activated quality control packages of inferior qual-ity are not doffed, such winding units stop with FLASH-ING yellow light.
D As all packages are doffed by the doffer, the lot is com-pleted, automatic accounting takes place.
D The group/lot changes to status ”DEFINED”.
D If ”WITH” (→ 3.5.15) had been entered in lot change re-port, print-out of the lot change report takes place.

Lot end, Accounting
This entry influences the currently running lot, pro-duction losses will occur in case of false entries.
This entry is possible only if the lot change had been initi-ated through ”Lot end with full packages”, or through ”Im-mediate lot end”.
Note:
This entry is necessary only if, e.g., the lot change has not been completed due to failure of a winding unit to report package doffing to the Informator (e.g. a winding unit has been removed from the machine).
D Entry ”Lot end, accounting” terminates the lot change..
D Depending on previous entry, lot end/accounting takes place similar to ”Lot end with full packages” or ”Instant lot end”.
Reduce
Information concerning the entry “Reduce” see “Change of winding unit range” under: Range reduction.
The entry applies only to the winding units taken out for ,Range reduction’!
FULL PACKAGES = Winding unit stop takes place with full packages.
IMMEDIATE = Instant stop of the winding units.
Package cone change at lot end
This entry controls the change of cones/sleeves at lot end.
WITHOUT = At lot end no empty cone/sleeve is inserted into the package cradle.

In this menu the control values of menu “Setup“ (Lot ...;
setup ...) of one group can be copied to an other group.
During this procedure, the control values D within the Informator,
D from Informator to a PC-Card (→ 3.1.17), or D from a PC-Card to the Informator
can be copied.
Consequently, with the PC-Card copying of the control val-ues of one group from machine to machine is also possible.
Opening the menu window places the groups already stored on display. The first group is selected.
Special symbol boxes:
➀
Key “Internal memory“: The groups stored in the In-formator are displayed.➁
Key “PC-Card“: The groups stored on the PC-Card are displayed.➂
Key “Copying“: For entry copy from ... to.➃
Key “Clearing“: For clearing the selected group.➄
Keys “Cursor up, Cursor down“: One line up or down in the display.➅
Keys “Leafing“: Leaf one page forward or backward.Possible only if more groups are stored than can be shown in one window.
