1TRS CHAPTER 1 GENERAL INFORMATION
1 General information
1.1 Introduction
This manual provides information on operating the computer control panel on the TRS
console. It includes instructions on how to make a grading program and how to verify
it. After that, the bunching station and the transport-part of the machine are explained.
Included in the manual is also a checklist of possible problems that the users
themselves can often solve and an overview of the machine maintenance.
Appendix 1 and 2 give a short overview of all setting-screens (menu's) and the last
page gives an index of the page numbers of all discussed menu's in this manual.
1.2 The TRS system
The TRS as a whole is a flexible, low-noise system consisting of the sorting computer,
the transport system and the bunching stations.
All bunching stations are virtually the same and are very easy to set for the length of
the roses to be bunched. If one station is malfunctioning, it is very simple to continue
with another.
Also it is possible to use multiple bunching stations for the same rose length when
there are many of them. This way, the machine (and workers) is equally employed.
This will significantly increase the production capacity.
By means of the 'flexible bunch setting' on the TRS, the machine can handle virtually
every variety, both those with large blooms and those with small blooms. Switching
from one sort to the other is done in no time at all.
The length measurement is done centrally by multiple electronic sensors and is very
reliable. With help of special DSP techniques, an image is made of every rose passing
by. In this image the stem will be found to determine the length and the thickness of
the rose.
The sensors continuously provide an optimal image. Possible filthiness will be
detected and excluded for the length measurement
The borders for the different length ranges (sorts) can freely be set with centimetre
intervals, which provides the facility for sorting 'intermediate sizes'.
Also the thickness of the rose will be measured accurately and can be used to
determine the final length class of the rose.
New is the maturity option. Here a camera monitors the bloom-bud accurately and
with this information the rose can be sorted on bud-quality (raw/ripe/color).

2TRS CHAPTER 2 OPERATING THE COMPUTER
2 Operating the computer
2.1 General
The control panel consists of a screen with four lines and 40 characters on every line.
The keys are distributed as follows:
-four function keys (A, B, C and D)
-four cursor keys
-10 numerical keys
-ESC (Escape)
-(Enter)
Figure 2.1.1 contains a graphical representation of the control panel.
Figure 2.1.1, The control panel.
The LC (liquid crystal) display is backlit (i.e. `illuminated from behind') to improve the
visibility of the characters on the display. If the machine has been switched off for a
certain period and the control panel has not been in use, this light will switch off
automatically.

3TRS CHAPTER 2 OPERATING THE COMPUTER
2.2 Menu
2.2.1 Using the menu system
When the computer is switched on, an information screen appears with data on the
sorter (see figure 2.2.1.1).
A W E T A - H O L L A N D
PROG 01 99 %FULL 00:00 HOUR
WHITE SUCC 6000 PIECES/h 000000 BUNDLS
A=INFO B=CHECK C=PROGR D=PRODUCTION
Figure 2.2.1.1, The information screen after switching the computer on.
This information screen provides a summary of the sorting results. The data refers to
the following:
A W E T A - H O L L A N D : Name of the dealer.
PROG 01 : Number of the program being used to sort.
WHITE SUCC : Name of the program.
99 % FULL : Percentage of filled forks on the machine.
6000 PIECES/h: Actual number of sorted roses per hour.
00:00 HOUR : Daytotal number of sorting hours (work time).
000000 BUNDLS : Daytotal number of sorted bundles.
The work time to make the bundles can directly be seen by looking at the daytotal
data.
The bottom line displays the options that are available by pressing the function keys:
-A = Information (requests information about the sorter or bunching stations)
-B = Verify (verifies operation of the sorter parts and bunching
stations)
-C = Program (setting length/thickness/rpb and program selection)
-D = Production (how much has already been sorted?, print if required)
Pressing these function keys leads immediately to separate main menus. In this main
menu an overview of further options will be found.

4TRS CHAPTER 2 OPERATING THE COMPUTER
By pressing a function key it is possible to choose between any of four different
menus. Pressing the <A>, for example, will display the menu shown in figure 2.2.1.2:
[A] 1 GRADER 4 VERSION NUMBER
2 PRODUCTION
3 TIME
A=INFO B=VERIFY C=PROGR D=PRODUCTION
Figure 2.2.1.2, Display after pressing function key <A>.
The '[A]' is displayed in the top left-hand corner of the screen, this is the 'menu path'.
The menu path states which choices were made to arrive at this menu. Here, an A is
displayed, in other words: only the function key <A> has to be pressed to get to this
menu. Also a black flashing block can be seen, this is the cursor. The function of this
cursor will be explained later.
Furthermore, this example gives four options to retrieve information. Each option is
preceded by a number:
-1 GRADER
-2 PRODUCTION
-3 TIME
-4 VERSION NUMBER
A menu option can be selected in two ways:
1) Choosing from the menu by pressing the preceding number. To see the time for
instance, which is preceded by the number 3, just press the <3> key, which will
cause the time menu to appear.
2) By using the cursor keys to move to the option of choice, for instance time.
Pressing <Enter> after the selection will lead to the chosen menu.
Remark: Pressing one of the function keys will (always) return you to one of the
main menus (A, B, C or D).

5TRS CHAPTER 2 OPERATING THE COMPUTER
In the example one will proceed to menu A3 (see figure 2.2.1.3):
[A3] DATE/TIME GRADER
DATE : 01-02-1992
TIME : 13:31
Figure 2.2.1.3, Display after pressing keys <A> and <3>.
The menu path is again displayed in the top left: [A3]. One have moved here by
pressing function key <A> and subsequently <3>. One can leave this menu by
pressing <ESC> (Escape), which brings you to the previous menu, in this case menu
A.
An example:
Suppose one is in menu C55. Pressing <ESC> leads to menu C5. Pressing <ESC>
again leads to menu C. In fact the same way back is taken, but in the opposite
direction.
Pressing <ESC> again displays the information screen with data about the sorter (see
figure 2.2.1.1). This applies for every main menu. So if one is in one of the main
menus (A, B, C or D), a return to the information screen is done on pressing <ESC>.
2.2.2 Different menus
The sorting computer is operated and controlled by menus. In appendix 1 the function
of the different menus is briefly explained and in appendix 2 a diagram of the different
menus is used to illustrate how a particular menu can be selected.
Broadly speaking, we can distinguish between three different types of menus:
-selection menus
-information menus
-setting menus
The selection menus have been discussed before, they are used to make a menu
selection.
The information menus only display data. For example the total number of roses,
bundles and operational hours.
The setting menus will be discussed below.

6TRS CHAPTER 2 OPERATING THE COMPUTER
2.2.3 Menu summary
The previous sections discussed the actions that have to be undertaken to work your
way through the menu structure (the collection of menu paths). It is shown that a
certain menu can be selected by entering a unique key sequence. This key sequence
is shown in the menu path which is displayed in the top left-hand corner of every
menu. A menu can also be selected by using the cursor keys.
The function keys are special keys that enables quick movement to one of the four
available main menus, any time and anywhere:
-A = Information (requests information about sorter or bunching stations)
-B = Verify (verifies working of the sorter parts and bunching stations)
-C = Program (setting length/thickness/rpb and program selection)
-D = Production (how much has already been sorted?, print if required)
It is possible to make further selections from these main menus.
A special menu is the information screen. It appears on the screen after the computer
is switched on, but it is also possible to view it when one is in a main menu (A, B, C
or D) and then presses the <ESC> key.

7TRS CHAPTER 2
In a setting menu a cursor is present which can be moved, using the cursor keys, to
the setting that the user wants to change. The cursor will only move to those positions
where something may be set.
For example menu D5. In figure 2.3.1.1 the setting positions are shaded. Only on
those positions the cursor can be placed.
[D5] BATCH EXCHANGE TYPE : abcdef
BATCH NR : 12345 TICKET No: AB1234
BRS ACTION : EMPTY CYCLE
Figure 2.3.1.1, In setting menus the cursor can only be located on the setting
positions.
Three types of data can be set:
1) numerical values (numbers)
alphanumeric values (also texts)
3) choice or selection (Yes/No or for example EMPTY CYCLE)
These are discussed separately below.
2.3.2 Numerical values (numbers)
In figure 2.3.1.1, BATCH NR. is a numerical value, a number may be entered. This is
possible with the keys in the numerical field.
The cursor is first moved using the cursor keys to the specified BATCH NR. The
cursor is now a flashing block, i.e. you are now in the point mode. The cursor is only
used to point to the data.
Simply by typing in the new value using the keys from the numerical section proceeds
automatically to the 'setting mode'. The cursor then becomes a flashing underscore.
When the number has been entered correctly, it has the desired value, the new setting
can be confirmed by pressing <enter>. The cursor now becomes a flashing block,

8OPERATING THE COMPUTER
If the number has not been entered correctly, it does not have the desired value, the
one must still be in the setting mode.
After pressing <ESC> while in the setting mode, the number retains its old value and
the setting mode is left.
<enter> had been pressed).
2.3.3 Alphanumeric values
Alphanumeric data in figure 2.3.1.1 are, for example, TICKET No. and TYPE.
This type of data is set in almost the identical way as that for setting numbers, the
user points to the piece of data to be changed with the cursor and selects the setting
mode (using <enter> or type something immediately). The numbers from the
numerical section are displayed immediately but cursor keys <↑↑>and <↓↓>must be
used for letters (in the setting mode). The numbers and the letters in the alphabet then
appear in succession. In other words, the cursor keys must be used for each letter
separately, namely the keys <←←>and <→→>to select the letter that is to be changed,
and <↑↑>, <↓↓>to change it.
The new text can be confirmed by pressing <enter> or rejected by pressing <ESC>
(old text returns). The user then proceeds automatically to the point mode.
2.3.4 Options
Some menus contain settings that have to be set in a particular 'mode' (on/off or other
option), for example the option to sort on thickness or not. It is then possible to make
a choice by pressing <enter> which will cause a new text to appear.
For example:
THICKNESS: NO (see menu [C51])
Another choice that may appear to the user is, for example, the question:
Are you sure : Yes / No
The cursor keys can be used to point to the desired option.
When pointing to the desired option, this is confirmed and immediately activated by
pressing <enter>.

9TRS CHAPTER 2 OPERATING THE COMPUTER
2.3.5 Summary of settings
From the preceding pages it can be seen that there are two different 'modes' in the
point mode(cursor is a flashing block) and the setting
mode
In the point mode a choice from various setting data can be made. The settings are
The setting mode can be reached in two ways: with the aid of the <enter> key
If a setting has been changed as desired, the change can be confirmed with the
of numbers, it is also possible to use the cursor keys for confirmation.
old value is retrieved by pressing
the <ESC> key (only if the setting mode is still active).
It is also possible to enter texts for alphanumeric data. This is achieved by using
<↑>- <↓↓>in the setting mode. Numbers and letters will then appear in
succession on the screen.

10TRS CHAPTER 3 INFORMATION MENUS
3 Information menu's
3.1 General
Pressing function key <A> results in an overview of the available information menus
of the TRS. It is not possible to change any settings in these menus. The menus
provide brief information on the following:
Menu [A] Information menus
1 - sorter (machine speed, %full, etc.)
2 - production (run/stop time)
3.2 Information screen
A special information screen is the screen that appears after the computer has been
switched on, or after pressing, for example, <A> <ESC>. This screen presents the
frequently to obtain a quick overview during the sorting process.

The DSP is a special computer for image processing. On the TRS, the DSP is used
among other things for length- and thickness measurement.
When the grader is not operating well due to the exceptional case of a DSP error, the
only advice is calling the dealer.

13TRS CHAPTER 4 SETTING THE PROGRAM
4 Button <C>: Setting the program
4.1 General
All settings, such as:
-the thickness YES/NO option
-length limits, outlets, number of roses per bundle
-thickness limits
are known as a sorting program.
Thirty of these programs are available. The number of the active sorting program, the
one currently used for sorting, is always displayed on the information screen.
The program number can be changed in menu [C1], PROGRAM SELECT. Valid
program numbers are 1 through 30. After a new program number has been set, the
'PROGRAM EXCHANGE' message appears on the display.
Menu [C1] can be used to assign a name to the program (see: alphanumeric data,
Chapter 2.3.3).
The active program can be copied to another program number in menu [C52]. This
can be used for the rapid creation of a new program which deviates only slightly from
the current sorting program.
The following sections contain an explanation for creating sorting programs.
It is recommended to take an unused program to gain familiarity with the operations
of the computer.
When a new program is made, it can be verified with menu [B1]. The menu's for
verification are described in detail in chapter 5.
Caution!: Due care should be taken when changing the program number while
the sorter is operating. The computer will immediately start to sort according to the
newly selected program.

14TRS CHAPTER 4 SETTING THE PROGRAM
4.2 Program configuration (MODE)
The first step in creating a sorting program is to establish the features to sort with.
For example: sort by length alone or by length & thickness.
This can be done in menu [C51] PROGRAM MODE. There are several options for
thickness, and when the quality option is also present, several options for maturity.
In this example we presume that all options are disabled, so, thickness and maturity
are set to 'NO'.
The next step, building a length program, will be discussed separate hereafter.
In menu [C1] it is also possible to set a maximum speed. For machines without
automatic motor control this is essentially a reminder. For some (large-bloomed) roses
better results are achieved by sorting at a lower speed (approx. 6000 f/h) than at the
normal speed (approx. 8600 f/h). In order not to forget the maximum speed at which
the roses may be sorted, it is possible to set a maximum here. If a different sorting
program is selected then the speed is automatically controlled, or a message appears
prompting the re-adjustment of the speed (only with manual speed control).
The remaining program settings are found in menu [C2] through menu [C4]. The
following sections contain more information on this.

15TRS CHAPTER 4 SETTING THE PROGRAM
4.3 Setting the length
Menu [C2] can be used to set the length and outlets. Figure 4.3.1 shows the screen
that appears here.
[C2] LENGTH NAME OUTLET -D-
1 028-038 30 CM 6 0 0 0
2 038 - 048 40 CM 5 4 3 0
3 048-058 50 CM 2 0 0 0
Figure 4.3.1, Screen for setting the length limits and outlets.
The cursor can only appear in the middle line of settings. If the other data are also to
be set, then the cursor keys <↑↑>, <↓↓>must be used. Cursor keys <←←>, <→→>are used
to select the piece of data on the setting line.
The data in this screen have the following meaning:
LENGTH Limits for length class in centimeters: lower limit at which the roses are cut,
followed by the upper limit.
The upper limit will be automatic the lower limit of the next class.
NAME Name assigned to this length class.
OUTLET Outlet (bunching station) where the rose in this class must be sent.
The roses are hung by their heads in the forks, and only that beneath the fork is
measured. For this reason the bud height of the rose must be accounted for in the
length limits. The bud height is therefore subtracted from the length limit. In this
example (figure 4.3.1) the bud height is 2 cm.
Figure 4.3.2 shows the setting to be adjusted for the rose length.
Figure 4.3.2, The bud height of the
rose must be accounted for when
setting the length.

16TRS CHAPTER 4 SETTING THE PROGRAM
If the desire exists to take advantage of the auction house's tolerance conditions, the
length limits can then be set very slightly shorter. The roses that are really slightly too
short, but still fall within the auction house's tolerance, can still be classified in the
(longer) length class.
In practice this means that some roses are not even cut off and this may save a lot of
centimeters.
It is possible to assign a name to every length class. If this is not done, then the lower
limit (of the class) will automatically be adopted as the name.
4.4 Setting the number of sorts
When setting the last length limit in menu [C2], the text 'GRADES' appears at the right
hand side of the display. The setting below that represents the number of length
classes and can be changed if desired (max number of sorts/grades is 12). See figure
4.4.1.
[C2] LENGTH NAME OUTLET -D-
5 068-078 70 CM 2 0 0 0 GRADES
6 078-999 80 CM 1 0 0 0 6
Figure 4.4.1, The number of sorts can be set at the last line.
Remark: After changing the number of sorts, the cursor automatically returns to
the first line of the sorting program (first sort).
4.5 Setting the outlet
Outlets can be set behind each length class (figure 4.3.1). If more than one outlet has
been set (with a maximum of four), the computer will select them consecutively.
Therefore, in Figure 4.3.1, the sequence for the fours will be:
5 - 4 - 3 5 - 4 - 3 5 - 4 - 3 etc.
The highest outlet number that may be set depends on the number of bunching
stations that the machine has. This is usually six (6).
Remark: It is also possible to bunch two grades separate with only one
bunching station. For this option the last column is marked with a '-D-'. This option will
be discussed later on in the chapter about 'double grades', chapter 9.1.

17TRS CHAPTER 4 SETTING THE PROGRAM
4.6 Setting the thickness
4.6.1 General
When sorting by thickness it is possible to set a thickness limit for each length class.
If a rose falls within a certain length class, but no longer meets the thickness
associated with this, then the rose will be moved to a shorter class until the thickness
limit is also met.
Momentary there are two different methods available for thickness grading. Selecting
the thickness option is done in menu [C51] PROGRAM MODE by pressing <enter>.
The options are:
-NO Don't sort on thickness
-%AVG sort on thickness with 'average thickness dependent' limit
-MIN sort on thickness with 'absolute (fixed) minimum' limit
Depending on the choice made, menu [C3] displays an other setting screen.
4.6.2 Thickness sorting with percentage of average thickness (%AVG)
The menu for this option, menu [C3], is presented in Figure 4.6.2.1.
[C3] NAME ThAVG-%AVG = Thmin %THIN
4 60 CM 3.0 100 0.0 0.0
5 70 CM 4.0 20 3.2 5.0
6 80 CM 5.5 10 4.9 6.0
Figure 4.6.2.1, Setting screen for sorting by thickness with %AVG.
The data have the following meaning:
NAME The name assigned to these length class. If this was left blank, then the
lower limit (cm) of the length class automatically appears as the name.
ThAVG Average stem thickness that the computer has measured for this class.
%AVG The setting: Percentage that the stem may be thinner (compared with the
average thickness for this sort).
Thmin The calculated minimum thickness limit.
%THIN The percentage of roses that are too thin that is now obtained.
Here, there is no thickness value to be set, but a percentage by which the stem may
be thinner in respect of the average. So, when the setting is smaller -> the more roses
will be sorted out on thickness. How many is sorted out can be seen by the
percentage too thin roses.
