1. General
Touch screen
The function of the Touch Screen is based on the active light matrix principle in the
infrared range. The optical elements of the light matrix are located behind the IR
transparent plastic frame in the front of the device. They are located in such a way that
their radiation extends slightly out of the front plate. Each emitter is assigned a receiver
that is located on the other side. A touch on the screen is detected by the simultaneous
inter-ruption of one or several channels in the X or Y axis.
Repeated touches and touches that cover an area greater than 20 mm x 20 mm are not
evaluated by the touch controller. Continuously interrupted channels caused by severecontamination and dirt or by the failure of an optical element are detected by the touch
controller and are no longer included in the evaluation.
Power up function test
The PCS smart runs through a function test of the Touch Screen with every start-up. All
the IR channels are evaluated and their signal levels compared with those of the initial
values. The initial values are determined before the device is delivered and stored in aretentive memory.
If one or several channel signals are below a minimum relative to the initial level, this will
be indicated on the screen with an error message and the DEF/DIRTY LED will be lit.
A reduced signal level of this kind is normally due to severe contamination of the IR
transparent plastic frame which consequently has to be cleaned. The Touch Screen
however remains fully functional.
Only an increase in the contamination of the screen will lead to the continuous
interruptions of one or several IR channels. IR channels that are continuously interrupted
will be detected by the touch controller and are no longer included in the evaluation. In
extreme cases this may mean that individual zones cannot be activated by touch.

1. General
ATTENTION
Do not touch the screen while the system is being started up and wait until your application
has started.
The Touch Screen carries out a function test during the start-up in which the signal levels
of the IR channels are measured.
Cleaning and maintenance
For operation ensure that the signal levels of the channels are not so severely reduced or
interrupted due to excessive contamination through dirt.
Clean the inside of the plastic frame of the device regularly with a damp soft cloth. Ensure
that the surface is not scratched or scoured, especially when removing hard deposits and
abrasive dusts.
Do not expose the front of the device to solvents which may corrode and loosen the plasticframe (frame material: polymethylmethacrylate, PMMA).
Screen saver
If no key on the Touch Panel is actuated for more than 1 hour, the background lighting will
be reduced to an intensity of 40 %. (This increases the life time of the Touch Panel).
In order to switch the background lighting to 100 % again just touch the screen of
the Touch Panel at any position whatever.
The switching over of the background lighting does not influence the functions of the
Touch Panel.

The input of this value determines the distance when the transport roller tablehas to start, before the theoretical cutting end is reached.S = 10 mmM =
Example: the preselected “Tail cut stop position“ is determined with 200 mm,
i.e. the cut will be stopped 200 mm before the slab is cut through.S = 200 mmM =
This is the safety addition to the theoretical cutting end, which is calculated bythe PLC.S = 10 mmM =

1. MACHINE TRAVEL DRIVE
1.5) DESCRIPTION OF CONTROL DEVICES
1.5.1) Proximity switch: MACHINE BACKWARD OFF (S 282)
This switch limits the return travel of the machine in all operation modes. When
it is actuated, it gives the signal “Machine home position”. Furthermore, it is
used for the synchronization of the encoder "Machine position".
1.5.2) Proximity switch: MACHINE BACKWARD SLOW (S 284)
The travel speed is switched over from "fast" to "slow" shortly before reaching
the rear end position by means of this proximity switch. This is effected in all
operation modes.
1.5.3) Proximity switch: MACHINE FORWARD OFF (S 286)
This switch limits the forward travel of the machine in all operation modes. If
the machine reaches this position while sitting on slab, the machine lifts up to
its upper end position in all modes.
Additionally, in semi-automatic and in automatic mode a cutting cycle will be
interrupted and the machine returns to home position.
1.5.4) Thermo switch: MACHINE DRIVE 1 (S 93)
This thermo switch supervises the temperature of machine drive 1 and will be
activated at approx. 150o C. At the same time an alarm on the Operator Panel
display will be generated. The drive itself will not be stopped.
1.5.5) Thermo switch: MACHINE DRIVE 2 (S 95)
This thermo switch supervises the temperature of machine drive 2 and will be
activated at approx. 150o C. At the same time an alarm on the Operator Panel
display will be generated. The drive itself will not be stopped.

1.5) DESCRIPTION OF CONTROL DEVICES
1.5.6) Incremental encoder: MACHINE POSITION (B 433)
Technical data:
Type: Hengstler RI 58 TD / 0250 ED.37KX
Supply voltage: 10 - 30 V
No. of steps: 250 steps/rev.
Channels: A+B channels, shifted by 90°
Circumference of measuring wheel: 500 mm
The evaluation of the encoder is effected by means of a counter module in the
PLC.
This counter is called "Machine Tracking".
The counter module counts the raising and the falling edges of the A + B
channels.
This means, the counter counts 1000 pulses per revolution of the measuring
wheel. Based on the circumference of 500 mm the following results: 1 pulse =
0,5 mm
The synchronization of the counter module will be made by a signal of the
proximity switch “MACHINE BACKWARD OFF“(Machine home position).
The counter module in the PLC calculates the actual machine position referred
to the home position. The shifted pulse channels enable increasing ordecreasing of the calculated position according to the direction of actual
machine movement.
The counter is also used for the determination of piece lengths when the
measuring roller is selected as length measuring system.
This is described in chapter "LENGTH MEASURING".
Furthermore, the counter is used for the following functions:
- to determine roller position
-
to determine the machine position for speed change from fast to slow inforward direction
- to move the shifting table

2. MACHINE LIFTING DRIVE
2.5) DESCRIPTION OF CONTROL DEVICES
2.5.1) Proximity switch: MACHINE LIFTING OFF (S 292)
This proximity switch limits the lifting drive moving direction “up” in all operation
modes.
2.5.2) Proximity switch: MACHINE PRELOWERING (S 294)
This switch is used for: 1. Prelowering procedure for any cut
2. Lowering procedure for tail cut.
1. Prelowering procedure
The signal of the switch activates a timer. The length of the timer is depending
on the strand thickness (in Level 1 mode the strand thickness is preselected by
the operator, in Level 2 mode the strand thickness from the higher level
computer is used).
The timer stops the drive when the skid is 5 - 10 mm above the slab.
2. Lowering procedure for tail cut
During tail cuts there is usually no strand underneath the skid.
Therefore the machine down movement must be stopped as described under
item 1. "Prelowering procedure".
In tail cut mode the skid is only travelled until the the prelowering position, i.e.
always over slab level.
General:
With the signal "Lowering" another fixed timer (independent on the format) is
started for approx. 3 seconds. That means the drive is started for approx. 3
seconds, the skid travels from prelowering position (approx. 5-10 mm above
the slab) into lowering position.After the timer run-down the machine sits on the slab.

3. TORCH DRIVES
3.4) DESCRIPTION OF ACCESSORIES
3.4.1) Incremental encoder: TORCH 1 POSITION (B 421)
Technical data:
Type: Hengstler RI 58 TD / 0250 ED.37KX
Supply voltage: 10 - 30 V
No. of steps: 250 steps/rev.
Channels: A + B channels, shifted by 90°
Circumference of measuring wheel: 235,62 mm (d0 = 75 mm)
The encoder is mounted on the shaft of the toothed wheel.
The evaluation of the encoder is effected by means of a counter module in the
PLC. This counter is called "Torch 1 Tracking".
The counter module counts the raising and the falling edges of the A + B
channels.
This means, the counter counts 1000 pulses per revolution of the measuring
wheel. Based on the circumference of 235,62 mm the following results:
1 pulse = 0,23562 mm
The synchronization of the counter module will be made by a signal of the
proximity switch “TORCH 1 BACKWARD OFF“ (Torch 1 home position).
The counter module in the PLC calculates the actual machine position referred
to the home position. The shifted pulse channels enable increasing or
decreasing of the calculated position according to the direction of actualmachine movement.
The counter is also used for several functions, like :
- positioning of the torch on the slab edge
- initial cutting distance
- remaining cut distance after torch meet
- etc.

7. TORCH TRACKING
7.6) CONTROL
7.6.1) GENERAL
The torch tracking system is used for the following :
- to optimize the cutting cycle time
- to guarantee a safe initial cutting and cutting out
- to send output signals, such as roller table start or cutting end, to other
PLCs at the right time
Torch tracking is necessary for all automatic cutting cycles.
Mainly a cutting cycle consists of the following steps :
1. Positioning of the torches at the strand edge
2. Switching on of the torch heating flame
3. Switching on of the torch cutting flame
4. Initial cutting of the strand with slow speed (initial cutting speed)
5. Acceleration via a ramp to the preselected cutting speed
6. Cutting with preselected cutting speed
7. Cutting out with reduced cutting speed
8. Transmission of the signal "Roller table start" to the PLC
9. End of cutting process, cutting flame off, heating flame off
10. Backward travel of torches and machine into home positions

7. TORCH TRACKING
7.6) CONTROL
7.6.2) PARAMETER
The following parameter are set in mm via the Operator Panel (screen Cutting
parameter ) installed in the control desk and are also indicated there.
- For initial cutting:
1. "INITIAL CUTTING DISTANCE"
To guarantee a safe initial cutting the torch is travelled approx. 40 - 60
mm (initial cutting distance) with reduced cutting speed (approx. 30 % of
the adjusted cutting speed).
- For cutting out :
2. Position "TORCH MEET"
This is the distance between the two torches, if they are as close together
as it is mechanically possible and if the proximity switch "Torch 1+2
Forward Off" is actuated. (Approx. 130 mm)
3. Position "CUTTING END"
This is a safety addition to the theoretical cutting end, which will be
calculated by the PLC. (Approx. 30 mm)
4. Position "ROLLER TABLE START"
The input of this value determines the position where the conveying roller
table has to start, before the cutting end is reached.
(Approx. 10 mm)
5. Position "CUTTING OUT"
This value determines the position before the theoretical cutting end is
reached, where the torch speed is switched over from the preselected
cutting speed into the reduced cutting out speed.(Approx. 30 mm)

6. Position "STOP during HEAD CROP CUT and TAIL CUT"
The cut will be interrupted if a head or a tail cut is preselected. The
corresponding torch remains in this position until the cutting line is above
the crop carriage (not for tail cut).
(Approx. 90 mm).In this moment the cut will be continued, so that the head piece can fall
down into the crop carriage.
Please refer to the FUNCTIONAL PROCESS , chapter HEAD CROP CUT
and chapter TAIL CUT.
Special features:
In the steps 3 - 6 the values to be entered are referred to the theoretical cutting
end, e.g.:
- The torch distance to the cutting end is the sum of the theoretical cutting
end + of the parameter "Cutting end".
- The torch distance to the position "Cutting out" is theoretical cutting end -
position "Cutting out".

7. TORCH TRACKING
7.6) CONTROL
7.6.3) CALCULATIONS IN THE CUTTING CYCLE
In each automatic or semi-automatic cycle the PLC calculates the positions of
the parameters described under item 7.6.2 and which have been entered via
the Operator Panel.
These position are calculated twice.
1. When the cutting flame is switched on after heating.
The PLC calculates the positions for both torches.
2. When there is a torch meet before reaching the a.m. positions
(normal cycle with two torches).
During preheating the torch position can be manually corrected.
When switching over from heating to cutting two other parameters are used in
order to calculate the cutting distance:
- Slab width
- Distance slab edge to the torches
In this case the calculation formula is as follows:
THEORETICAL CUTTING END =
DISTANCE SLAB EDGE TO TORCH 1 (2) + SLAB WIDTH

7. TORCH TRACKING
7.6) CONTROL
7.6.3) CALCULATIONS IN THE CUTTING CYCLE (cont.)
By means of the theoretical cutting end the PLC can calculate all other important
positions in the cutting cycle.
EXAMPLE : - Distance slab edge to the torch heating position: 15 mm
- Slab width 2000 mm
- Cutting end 10 mm
- Torch meet 120 mm
Then the PLC calculates the position for the theoretical cutting end as follows:
EXAMPLE: - Edges detected
- Torch 1 position = 355 mm
- Torch 2 position = 355 mm
At the moment when the cutting flame is switched on the PLC calculates the theoretical
cutting end positions as follows:
For torch 1 :
Theoretical cut end pos = Actual pos. + Dist. torch 1 to slab edge + Slab width
2370 = 355 + 15 + 2000
For torch 2 :
Theoretical cut end pos = Actual pos. + Dist. torch 1 to slab edge + Slab width
2370 = 300 + 15 + 2000
With these calculations both torches are working like in "Only 1 torch" mode.
The advantage is: If one torch fails during cutting it can be deselected (on the
Preselection screen of the Operator Panel).
The deselected torch then travels back to home position and the other torch can fullfil thecut without any further operator action.

7.6.3) CALCULATIONS IN THE CUTTING CYCLE (cont.)
When the torches meet during cutting a new calculation for torch 1 will be made.
At torch meet torch 2 finishes the cut and travels back to home position.
For torch 1 the calculation of the theoretical cutting end will be made as follows:
EXAMPLE: - Torch Meet- Torch 1 position : 1310 mm
- Torch 2 position : not relevant for the calculation
Theoretical cut end pos = Actual position T1 + "Torch meet"
1430 = 1310 + 120
Based on this value the calculations for the residual cutting cycle will be made.
EXAMPLE: - Parameter Roller table start = 10 mm
- Parameter Cutting end = 10 mm
Roller table start = Theoretical cut end pos - Parameter Roller table start
1420 = 1430 - 10
Cutting end = Theoretical cut end pos + Parameter Cutting end
1440 = 1430 + 10

8.2) BY SLAB WIDTH SYSTEM
A = A1 + A2
TE1 = (A - W) / 2 Torch 1 edge position
TE2 = (A - W) / 2 Torch 2 edge position
The edge is calculated by the actual slab width as shown above.
The torch travels to this calculated edge position. After stopping at the edge, the heating
flame is ignited and the operator can now see whether the calculated edge is equal to the
actual edge. If a correction is necessary, it must be done by the touch keys "Torchforward - backward".
The correction value is stored with cutting start. For the next cut the torches travel to the
calculated slab edge under consideration of the correction value.

9. MEASURING ROLLER
9.6) MEDIA DIAGRAM FOR MEASURING ROLLER
9.7) CONTROL
The measuring roller is a part of the length measuring device. When the strand head
reaches the measuring roller, the PLC receives a signal from the caster tracking system
‘’Measuring roller up”. With this signal the solenoid valve will be switched on (solenoid
valve opened currentless). Thereby the cylinder pressure is neutralized and the
measuring roller by the counter-weight travels upwards to the strand.
The measuring roller will be pressed against the lower side of the strand. After this the
built-in encoder continuously generates impulses as long as the measuring roller is
pressed against the slab. The counter card counts the impulses and the PLC is able tocalculate the measured length.
After the strand end passes the measuring roller, it is pressed down to home position by
the cylinder.

10. LENGTH MEASURING
The measuring roller and the machine position encoder are used for measuring of piece
lengths.
The measured piece length is indicated on the Operator Panel and is determined as
follows:
-When the strand head is 300 mm behind the measuring wheel center line the roller ispressed against the strand by means of a signal from caster tracking system.
- The strand movement causes the turning of the measuring wheel.
- The machine position is detected by the machine position encoder.
- The impulses generated thereby are counted by the counter modules in the PLC. The
PLC program calculates the actual piece length from the impulses.
- This calculated piece length is compared with the preset value ”cut length“.
- When the strand reaches a length which is approx. 0,5 m less than the preset length,
the machine is prelowered. The length, where prelowering is initiated, is stored as
parameter in the Operator Panel and can be changed, if necessary.
- When the actual piece length and the preset length are equal, the machine is lowered
on the strand.
NOTE:
The measured piece length is used to trigger prelowering and lowering but only when the
machine is operated in AUTOMATIC mode.

12. CUTTING CYCLES
12.1) GENERAL
The following description describes the steps which are executed at each cut.
These steps also apply for special cuts (head crop cut and tail crop cut).
Therefore in the descriptions of special cuts only the differences to normal cut
are detailed.
It is assumed that full automatic operation of the machine is desired. Therefore
the machine should be controlled from the Control Desk. In this case the
machine PLC will receive the slab length setpoints and the kind of cut via
Ethernet interface or via the Operator Panel by using program 1 or program 2
and the machine will operate fully automatic.
- If Automatic is selected, the machine will execute the cut automatically
according to the preset slab length.
- If Semi-Automatic is selected, the machine must be prelowered and
lowered by the operator, because the slab length setpoints are not
evaluated in this operation mode.
- If Manual is selected, the whole cutting cycle must be executed manually
by using the touch keys on the Graphic Panel.
The machine is equipped with a pair of main torches.
Special cuts, such as head and tail cuts, are usually made as described with 2
torches (one pair), but it is also possible to make these cuts with 1 torch only.

12. CUTTING CYCLES
12.2) NORMAL CUT
12.2.1) With two torches (1 pair)
Machine prelowering:
- If the machine is operated in Automatic operation mode, prelowering is
initiated automatically. This is described in chapter LENGTH MEASURING .
If the machine is operated in semi-automatic operation mode, prelowering
is initiated by pressing the touch key “Prelowering” on the Operator Panel.
- With prelowering position the torches travel fast forward to the edge
position.
- On the edge the heating flames turn on.
Machine lowering:
- If the machine is operated in Automatic operation mode, lowering is
initiated automatically. This is described in the chapter LENGTH
MEASURING.
If the machine is operated in semi-automatic operation mode, lowering is
initiated by pressing the touch key “Lowering” on the Operator Panel.
- The cutting flames turn on.
- The torches start to move forward with initial cutting speed. This speed is
approx. 30 % of the normal cutting speed. The torches travel approx. 50mm with initial cutting speed. This is the initial cutting distance. Such a
procedure is necessary to cut the slab edge through.
- After passing the initial cutting distance the torches accelerate to normal
cutting speed.

12. CUTTING CYCLES
12.2) NORMAL CUT
12.2.1) With two torches (1 pair)
- Both torches cut with normal cutting speed until “torch meet“.
- After “torch meet“ the heating and the cutting flame of torch 2 are turned off
and torch 2 travels with fast speed back to home position or to edge
position. Torch 1 proceeds to cut with normal cutting speed.
- Torch 1 cuts with normal cutting speed for approx. 70 mm.
- Then the cutting speed is decreased to approx. 70 % of the normal cutting
speed. This is cut out speed. With this decreased speed torch 1 cuts
approx. 50 mm.
- Torch 1 returns to home position. At the same time the heating and the
cutting flame turn off.
- The machine lifts up and travels to home position. Depending on the preset
cut length for the next slab there are two possibilities:
1. The new preset cut length is shorter than the machine distance to home
position. The machine will stop to move when receiving the signal
“Prelowering” and a new cutting cycle will be started when receiving the
signal “Lowering”.
2. The new preset cut length is longer than the machine distance to home
position. The machine reaches home position and will wait there for the
signals “Prelowering” and “Lowering”.

12. CUTTING CYCLES
12.2) NORMAL CUT
12.2.2) With one torch
If one torch is out of order a cutting cycle can be executed with one torch only.
The cut with one torch must be selected by the operator. He must select torch
1 or torch 2. It must be considered that a cutting cycle executed with only one
torch takes a longer time than a cycle with both torches. Special cuts (head
crop cut and tail crop cut) can also be executed in this manner.
For that the machine must know the width of the slab. (Via Ethernet interface
or by operator input via the Operator Panel).
- Prelowering, lowering, edge detection and initial cutting are executed in the
same manner as cutting with two torches.
- When the torch comes approx. 50 mm close to the opposite edge of the slab
(this position is calculated by the torch encoder) cutting will be preceded with
cut out speed.
- The movement of the shifting table and roller start are controlled in the same
manner as cutting with two torches.

12. CUTTING CYCLES
12.3) HEAD CROP CUT
12.3.1) With two torches (1 pair)
- The machine is in home position.
The hot strand head approaches the measuring roller.
- When the hot strand head is above the center line of the measuring roller,
the GeGa PLC receives the signal “Measuring roller up” from the strand
PLC. With this signal the measuring roller is pressed against the strand.
- After a short time the strand PLC sends a second signal "Start measuring".
With this signal the measuring roller starts measuring.
- 500 mm before reaching the preset crop length the torch cutting machine
will prelower. The brakes of both machine drives remain closed.
- Both torches are travelled to the strand edge. When reaching the strandedge the heating flames of both torches are switched on.
- When reaching the preset crop length the machine will lower and the
magnetic brakes of both travelling drives are opened, the machine is now
dragged by the strand (synchronous travel).
The cutting oxygen at both torches is switched on and both torch drives are
started with initial cutting speed.
- Cutting the strand with initial cutting speed.
- Cutting the strand with cutting speed.
- Reaching the proximity switch “Torch meet”. Torch drive 2 is stopped,
cutting oxygen and heating gas of torch 2 are switched off. Torch 2 travels
back to home position or to edge position. Torch 1 continues cutting with
cutting speed.

12. CUTTING CYCLES
12.3) HEAD CROP CUT
12.3.1) With two torches (1 pair)
- Torch 2 reaches the home position.
- Torch 1 reaches the stopping position for head crop cutting. The cut is
stopped, that means cutting oxygen is switched off and the torch drive is
stopped.
- The machine is still dragged by the strand.
- When the machines reaches the "head cut restart" position the cutting
interruption for torch 1 is deactivated, that means cutting oxygen at torch 1
is switched on again and the torch drive speed is increased to cut out
speed via a ramp.
- Torch 1 reaches the position cutting end. Torch drive 1 is stopped, heating
and cutting flame are switched off. The head crop is cut through.
- The machine is travelled into the upper end position. Torch 1 is travelled
into home position or to edge position. The machine is travelled backward
to home position with fast speed (24 m/min.). The following strand is
pushing the head piece in front of it.
- Before the machine reaches its home position it receives the signal
“Prelowering” from the length measuring. The machine drive is stopped.The torch cutting machine will prelower. The brakes of both machine drives
remain closed. The two torches are travelled to the strand edge. When
reaching the strand edge the heating flames of the two torches are
switched on (normal cut).

12. CUTTING CYCLES
12.4) TAIL CROP CUT
12.4.1) General
The tail crop cut is a partial cut only.
A complete cut is not possible, because the tail piece would fall down into the
sinter channel underneath the shifting table.
Cutting above the crop car is not possible because of the mechanical design.
The handling of the last slab with the tail piece at the end requires special
sequences of the torch cutting machine and of the roller table in this area.
The sequences are described in the chapter FUNCTIONAL PROCESS .
The cutting cycle itself is shown on the following pages.

the Strand PLC reports the “Simulation”.
The simulation mode automatically resets if the Strand PLC resets the simulation flag.
2. The measuring roller is lifted with the signal “Measuring roller up“ from the strand
tracking system.
3. With the signal “Measuring start“ the strand length is calculated according to the
casting speed which is transferred from the strand tracking system.
4. According to the cutting length setpoints (Level 2 or local) the machines are pre-
lowered and lowered. In computer mode the strand width, which is received in the
cutting setpoint, is used, otherwise a fixed value (which is stored on the TCM PLC) is
used.
5. With the signal “Lowering“ generated from the length measuring (preset cutting length
is reached) the machine is travelled according to the casting speed. In order to
guarantee a travelling of the torch cutting machine with casting speed, the casting
speed in simulation mode must be higher than 1,2 m/min.
6. The further procedure corresponds to the functional process on the following pages
and depends on the cutting kind selection (head crop cut, normal cut). All signals of the
simulated “air cuts“ are transferred to Level 1 according to the Interface description.
