operation. Taking delivery by the Purchaser does not release the Supplier from
his guarantee obligation.
IX. Guarantee
(1) In case of faults which are not covered by the Performance
Guarantee specified under para (2) of this article, KKA undertakes to remedy any
defect resulting from faulty design, materials or workmanship either by
repairing the defective part free of charge or by replacing it by a new one
which is delivered ex works. Upon replacement, the defective part shall again
become the property of KKA
KKA's liability is limited to defects which occur within 6 months
after first commissioning of the supplied equipment, with notice being given by
the Purchaser immediately after the defect appeared. If plant operation is
interrupted for reasons for which KKA is liable, the guarantee period of those
parts which caused the stoppage shall be extended accordingly by the shut-down
period.
For repaired or replaced parts KKA shall assume liability to the
same extent as for the originally supplied equipment, however not longer than 3
months after expiration of the guarantee period of the originally supplied
equipment.
(2) KKA shall be liable for non-performance of guaranteed
performance and consumption data only in so far as non-performance is verifiably
attributable to KKA, any required reconditioning work shall then be made by KKA
free of charge. Upon satisfactory guarantee tests or, if such guarantee tests
are not made, after acceptance of the equipment by the Purchaser, all KKA
liabilities concerning performance and consumption data are fulfilled.
(3) If KKA fails to remedy a defect as defined in art. IX para (1)
or (2) within a reasonable period of time, or if the reconditioning work does
not bring about the desired result, the Purchaser is entitled to a reasonable
price reduction accordingly.
(4) If shipment, erection, commissioning, guarantee tests or
acceptance of the plant are delayed for reasons for which KKA is not liable,
KKA's liabilities according to para (1) or (2) expire 12 months after
notification of readiness of shipment, at the latest.
(5) KKA's liabilities only cover faults which occur under the
contractually defined operating conditions while the equipment is being
correctly used and which are directly attributable to causes dating back to the
period before passing of risk.
Any defects which are attributable to chemical or electrical
effects, normal wear, improper arrangement or bad plant maintenance by the
Purchaser, or attributable to non-compliance with the operating instructions are
not covered by KKA's liabilities.
(6) The Purchaser shall schedule a reasonable period of time which
allows the Supplier to repair the defective parts or to replace them
respectively. KKA shall be released from all liabilities if the Purchaser does
not allow a sufficient period of time.

(8) In the event that KKA shall supply drawings or other documents
or data for work which shall be carried out on the part of the Purchaser, KKA
shall be liable for such services only in so far as a special remuneration was
paid for these services. If such a remuneration is paid, KKA guarantees correct
and faultless performance according to the state of the art and that the
eventually agreed performance and consumption data are reached.
KKA's liability is limited to free-of-charge engineering services
which are required to remedy eventual defects which occurred within 6 months
after first plant commissioning and not later than 12 months after having
rendered the respective services with notification being given by the Purchaser.

full or in part, the Purchaser is entitled to terminate the Contract in case of
complete impossibility, whereas in case of partial impossibility the Purchaser
is entitled to an appropriate price reduction. In case of termination of the
Contract by the Purchaser, KKA is entitled to an adequate compensation for the
services and work carried out so far.
If impossibility of performance occurs during a delay in
acceptance or for reasons for which the Purchaser is liable, the Purchaser shall
pay the contract price less the expenditures saved by KKA due to impossibility
of performance.
(2) KKA is entitled to terminate the Contract on the grounds of
unforeseen circumstances as defined in art. IV, para (4) which render contract
performance completely or partly impossible. KKA is then entitled to a
compensation covering the expenditures and services rendered so far.

Profile monitor / data viewing screen
MC 68 K02.K1
DESCRIPTION:
Various data presentations are displayed on the monitor, in combination with a
scanning measuring sensor. Different screen displays can be selected as required
by the application.
The programme for the monitor screen display is stored on EPROM. When the unit
is switched on, the programme is immediately loaded and started by means of an
autostart command.
After interrogation of the parameters preset on the measurement system, both the
horizontal and vertical scales for the profile representation are computed and
displayed correspondingly. The utilization of the viewing screen is thereby
optimized; that is, for a shorter traversal path of the measuring sensor the
horizontal scale is spread; the vertical scale is likewise spread for smaller
tolerance values.
The profile is displayed in the form of a histogramme. The bars are drawn during
the scan; hence, the actual value is indicated immediately after computation of
the measured values. The position of measurement is indicated by a mark which is
displayed in synchronism with the motion of the measuring head.
If the measured values exceed the preset tolerance limits, the bars which lie
outside the tolerance range are identified by a different colour. Thus, an
inadmissible deviation is easily recognizable even from a greater distance.
In addition to the histogramme bars, further information is presented
graphically and numerically; this information is described by means of the
following figures.

This screen display includes the elapsed time counter with three different
ranges. The following times are indicated:
1. Total elapsed operating time
2. Time elapsed during automatic operation, for which at least one control
loop must be in automatic mode.
3. Time elapsed during manual operation
Moreover, various parameters which are largely independent of the product, that
is, which remain constant despite different products, can be set on this
display. The following parameters are indicated for the present measuring and
control system:
[code basic settings]
The code number must be entered in this line; only with correct entry of the
code number, a change in the basic settings is possible.
[time (hhmm)]
The current time is entered in hours and minutes.
[date (ttmmjjjj]
The current time is entered as day, month, and year.
[start of shift in minutes after 0 o'clock]
The beginning of the shift is entered for the shift after 0 hours - as a rule,
the beginning of the morning shift.
[length of shift in minutes (greater than 60 minutes)]
The duration of the shift including breaks is entered.
[print error messages (0/1)]
After occurrence of a fault, the message is printed in clear text immediately
upon entry of [1]
[(print roll profile (0/1)]
After the roll change signal, the profile of the last roll is printed upon entry
of <1>
[print shift record (0/1)]
Upon entry of [1], the record is printed after pressing of the [shift
changeover] key. If the associated parameters for the shift beginning and
duration have been preset, the record is printed automatically at the end of
the shift.
[print order record (01)]
Upon entry of [1], the record is printed either by pressing of the [order
changeover] key or by changing of the order number.
[print roll record (0/1)]
Upon entry of [1], the roll record is printed automatically after 200 individual
rolls.
Attention!
After printing, all records and the roll profile screen display are reset and
restarted.
[optimize set value]
The factor X is entered for optimizing the set value. In the case of positive
factors, optimizing is performed at the positive tolerance limit. For a factor
of 0, no optimization is performed.
The following applies for positive factors: Wo = W + OT - (2S * [X])
The following applies for negative factors:
Wo = W - UT + (2S * [X])
Wo denotes the optimized set value
W denotes the set value
UT denoted the lower tolerance limit
OT denotes the upper tolerance limit
[X] denotes the absolute value of the factor
S denotes the standard deviation of the last
single profile.

All existing product numbers under which the corresponding product parameters
and data records have been stored in the memory are listed. The battery-backed
data memory has a capacity of about 200 product data records for standard
systems. The memory capacity depends on the length of the product data records
(the number of lines in a data record) and may therefore be smaller with
comprehensive systems.

This screen display also includes relevant,client-specific product parameters
for reasons associated with measurements or as desired. These parameters can be
stored under a freely selectable product number in the battery-backed data
memory and are thus available at any time.
The display is conveniently subdivided into two columns.
1. [actual] column
The values of the instantaneously valid data record are indicated here.
2. [next] column
The next data record is presented here. This data record can be entered
or transferred either by means of the keyboard or, as an extension, from a
host computer system through an interface RS 232.
The entries for the product and order numbers may consist of a maximum of 15
alphanumeric characters; all other entries may comprise a maximum of 15 numeric
digits The corresponding line is selected for the entry by pressing the cursor
keys, and the line is displayed in blue. Every entry must be terminated by
pressing the [Enter] key.
ATTENTION!
After completion of the entries, the product number
must be reentered before storing of the product data
record in the memory or
transfer from the [next] column to the [actual] column. For
reasons of security, this number is deleted during alterations in a
data record, in order to avoid possible errors
in storing the data record, for
example, overwriting of a data
record which is still valid.

The record includes all individual rolls manufactured under the specified order
number, together with the associated quality data.
Individual rolls whose quality data cannot satisfy the desired quality criteria
are deleted from this record and documented in a rejection list.
Individual rolls are eliminated in the following manner:
1. The corresponding individual roll is selected by means of the cursor keys.
(The line is emphasized in colour).
2. After pressing of the [Enter] key, the data on this roll are deleted from
