On this page, you can calibrate the slab height reading sensor.
Calibration:
Set a filter time in case the reading value oscillates continuously in short periods.

WITHOUT SLAB	WITH SLAB
Remove any material between the conveyor belt and the sensor. Measure the distance (in mm) between the sensor and the belt, then enter it in the “DISTANCE” field. Press the acquisition button	Insert a high slab, between the conveyor belt and the sensor. Measure the distance (in mm) between the sensor and the surface of the slab, then enter it in the “DISTANCE” field. Press the acquisition button

At the end of the calibration, check the visible slab height in the “SLABHEIGHT” field. If the visible measurement does not match the actual measurement, repeat the calibration.

Horizontal Correction:

Parameter	Measurement Unit	Range	Description
Horizontal correction descent:	mm	-9999.9 ÷ 9999.9	Advance or delay space from the start of the piece, with which to anticipate or delay the head descent. Positive values: advance descent. Negative values: delay descent
Horizontal correction ascent:	mm	-9999.9 ÷ 9999.9	Advance or delay space from the end of the piece, with which to anticipate or delay the head ascent. Positive values: delay ascent Negative values: advance ascent

Example of use:

The conveyor belt moves from left to right.
A = head descending at the beginning of the piece
B = head ascending at the end of the piece
In the descent phase (start of the piece), head A descends late and does not smooth the initial part of the piece. To fix the problem, you need to advance the descent.
In the ascent phase (end of the piece), head B rises late and risks damage to itself and the conveyor belt. To fix the problem, you need to advance the ascent.

Orthogonal Correction:

	Measurement Unit	Range	Description
Orthogonal correction ascent upper edge:	mm	-9999.9 ÷ Max correction	Advance or delay space from the upper edge of the piece, with which to anticipate or delay the head ascent. Positive values: delay ascent Negative values: advance ascent
Orthogonal correction descent upper edge:	mm	-9999.9 ÷ Max correction	Advance or delay space from the upper edge of the piece, with which to anticipate or delay the head descent. Positive values: advance descent Negative values: delay descent
Orthogonal correction ascent lower edge:	mm	-9999.9 ÷ Max correction	Advance or delay space from the lower edge of the piece, with which to anticipate or delay the head ascent. Positive values: delay ascent Negative values: advance ascent
Orthogonal correction descent lower edge:	mm	-9999.9 ÷ Max correction	Advance or delay space from the lower edge of the piece, with which to anticipate or delay the head descent. Positive values: advance descent Negative values: delay descent

Example of use:

C = direction of bridge movement
A = head ascending phase
B = head descending phase
Head B descends late relative to the lower edge of the piece, risking not smoothing the lower part of the slab. To solve this problem, you need to advance the descent.
Head A rises ahead of the upper edge of the piece, risking not smoothing the upper part of the slab. To solve this problem, you need to delay the ascent.

From the corrections page, you can access the “Slab Shift Compensation” page.
→

In this page, you can input an offset value for each individual head. The value you enter will virtually modify the position of the head, either increasing or decreasing the distance between the head and the sensor bar.

Example: If you set the value to 100mm for head #1, it's as if the distance between the sensor bar and head increases by +100mm. Conversely, if you enter the value of -100mm, it's as if the distance between the sensor bar and head decreases by -100mm.

There are two buttons on the page that allow you to reset and progress the input offset values.

Example: If the first head has an offset value of 10mm, and you want a progression of 20mm for the other heads, you enter the value 20 in the “progression of” field. Automatically, the offset fields are filled with the value of the previous head +20mm. So, in this case, head 2 would have an offset value of 30mm, and head 3 would have 50mm.

Attention: Only enter offset values if there is slippage of the slab.

On these 2 pages, it is possible to set, for each head and for the brush, the distance between the sensor bar and the head center.

→

The page is divided into:

	Area for displaying belt (line) position, bridge position and last piece length
	Area related to the CPU of control C1R44. In detail: Fw name : firmware present in the instrument and its checksum; Task time : average CPU cycle time with indications of Maximum and Minimum Scan Time; Area compare time : average time at which the stored zone of the sensor bar status is analyzed to decide whether a head should be idle or active; CPU time : total time since the CPU is in the RUN state (hh:mm).
	In the green field, you can set the head number. The bar below displays the memory content. The bottom bar displays the status of the slab detection sensors.
	Area related to the state of the communication network between CANBUS instruments. In detail: ERR FLAGS : error code represented as a series of bits; BUS LOAD : network traffic load as a percentage; MAX BUS LOAD : maximum percentage of traffic detected in the bus; MAX RX ERR : maximum number of receive errors; MAX TX ERR : maximum number of transmit errors.

→

By pressing the RESET button, the slabs are cleared from memory. So, the slabs inside the machine will NOT be polished.
The reset is mandatory after manual belt movement; otherwise, the machine won't start.

→

On the abrasive change page, you can find the code of the used abrasive and the working duration (how many meters it has traveled during processing before wearing out).
After replacing the worn abrasive, you should check the number of the head to which the abrasive was changed and then press the confirmation button. Pressing confirm resets the “meters worked” display.
After an abrasive change, enter the corresponding new code. The confirmation button appears only if you type the code.
In case of the “abrasive change button (I 22)”, the tool change page opens automatically.

To perform operations / view data on this page, it is necessary to have the parameter PG 12 = ON and the “Enable abrasive CTRL” option active.
The arrows allow you to change the abrasive number displayed.
The filter time is a parameter that filters the reading of the analog input. The value is valid for all analog inputs related to thickness control.

HEAD UP:

Raise the head
Measure and then set the value in the “DISTANCE” field that corresponds to the measurement between the beginning of the abrasive and the surface of the conveyor belt (measure in mm)
Enter the value read in the “READING” field in the “SETTING (bit)” field or press the button

HEAD DOWN:

Lower the head
Measure and then set the value in the “DISTANCE” field that corresponds to the measurement between the beginning of the abrasive and the surface of the conveyor belt (measure in mm)
Enter the value read in the “READING” field in the “SETTING (bit)” field or press the button

The partial descent advance of the heads allows for correct positioning of the head on the material, anticipating the position of the head before it descends.
The descent advance must be adjusted based on the pressure of each individual head. The higher the pressure, the lower the value of the relative head advance.
The suggested table is adjustable. Once the correct advance adjustment based on the head pressure is found, fill in the table so it will be helpful in the future.
The global advance allows you to enter a value that will then be applied to all heads.
The default value sets 100% for all heads.

The ascent advance of the heads allows for correct head rise to avoid excessive overhangs or lack of processing on the edges.
The ascent advance must be adjusted based on the pressure of each individual head. The higher the pressure, the lower the value of the relative head advance.
The suggested table is adjustable. Once the correct advance adjustment based on the head pressure is found, fill in the table so it will be helpful in the future.
The global advance allows you to enter a value that will then be applied to all heads.
The default value sets 100% for all heads.

On this page, you can see the status of all sensors.
Green LED = enabled sensor
Yellow LED = warning, the sensor is not reading
Red LED = alarm, the sensor is always reading

On this page, you can force the activation outputs of the head motors, provided you are in manual mode. To do this, simply press the button with the number of the head you want to activate, and a LED indicating its status will be displayed on it.
LED on = motor on;
LED off = motor off.

→
On this page, you can see the status of each head. LED on = head enabled; LED off = head disabled. Head enabling and disabling is done through the selector.

→
On this page, you can view the current speed of the conveyor belt, modify the automatic and manual speeds. In manual mode, you can also move the conveyor belt in JOG by pressing the relevant buttons to move it forward or backward. If the conveyor belt is manually moved, an automatic reset of the pieces is required to perform an automatic start.

→ By pressing this button, you can unlock the doors. The machine goes into emergency mode immediately.

Lubrication is performed if the command on the Options page : Enable Lubrication is active. This command allows you to perform lubrication cycles in time.
“LUB. TIME ON” (PG 17) activates the lubrication output for the set time.
“LUB. TIME OFF” (PG 18) deactivates the lubrication output for the set time.
If the feedback input of the lubrication circuit under pressure (I 14) is not detected during lubrication, a warning message will appear.
= Lubrication OFF
= Lubrication ON
= Lubrication ALARM

Ensure the sensors' readings are accurate. A sensor that consistently reads can cause unwanted head descents!
With parameter PS03 > 0, an alarm will appear if a sensor is constantly active. If a sensor is faulty, it must be replaced.
