Glass edge sensor adjustment on the Rapidline/Galactic
Baumer UNAM 12P8910-S140D: Hegla part# 31-0209-8157
***IT IS VERY IMPORTANT NOT TO REMOVE THE NOZZLE FROM THE SENSOR. THE NOZZLE IS CALIBRATED EXACTLY TO THE SENSOR***
The Baumer UNAM 12P8910-S140D Sensor is an ultrasonic proximity sensor.
- The sensor must be taught onto glass or sheet metal 1mm thick .
- The sensor must be taught to NO-Contact.
- Mount the sensor so that bottom of the nozzle is 30mm above the table top / felt.
How to teach the sensor (manual function without software):
- Remove the cable connection plug on the top of the sensor (sensor has no power) and wait 1 minute, then re-connect. The sensor can only be taught during the first 5 minutes after it is switched on!
- Start the teach in process by applying 24V to the white teach in wire for 2 seconds.
- The green LED on the sensor blinks slowly (2Hz)
- Place the 1 mm glass or sheet metal under the sensor
- Apply 24V to the teach in wire briefly (>200 ms) the sensor looks for the glass and teaches itself (LED flashing fast) this takes approx. 5 seconds. Then the LED stops flashing and is constantly green.
The sensor is now taught for all glass thicknesses that are the same or thicker than the glass that was used for the teach in process.
How to teach the sensor (with software in HMI):
- Remove the cable connection plug on the top of the sensor (sensor has no power) and wait 1 minute, then re-connect. The sensor can only be teached during the first 5 minutes after it is switched on!
- Activate the Service Menu
- F9 Setup
- F5 Setup (Pic.1)
- Start the teach in process by pressing F1 Teach sensor button for 2 seconds (Pic.2).
- The green LED on the sensor blinks slowly (2Hz)
- Place the 1 mm glass or sheet metal under the sensor
- Press the F1 Teach sensor button again briefly (>200 ms) the sensor looks for the glass and teaches itself (LED flashing fast) this takes approx. 5 seconds. Then the LED stops flashing and is constantly green.
- F11 to return to working screen
- Switch off Service screen
The sensor is now taught for all glass thicknesses that are the same or thicker than the glass that was used for the teach in process.

Adjusting the cutting head:
To get a correct cut the X- and Y-Offset from the sensor to the cutting head must be adjusted in the Software. The Offset value can be changed in the MK’s (Machine constants).
To do this you must:
- Activate the Service Menu
- Press F12 Diag. screen (Pic.3)
- F6 Machine Data
- F6 Edit Machine Data
Scroll down the left list until you reach “MK_TECHNOLOGIEDATEN2”.
In the right window you have the adjustable values and in the bottom window is a short description for every value. Value [0] is the X-Offset and value [1] is the Y-Offset.
Pic.3
Measure the distance from the glass sensor to the cutting wheel in X and Y direction. Enter the values in mm in the Value [0] for the X-Offset and value [1] for the Y-Offset.
Now cut a plan with just a trim on the front and bottom edge of the glass. Measure the exact size of the trim that was cut. Adjust the values in the “MK_TECHNOLOGIEDATEN2” to accommodate for any deviations. This has to be repeated until the trims have the correct dimensions.
Additional adjustments in the MK’s:
All other adjustments on the Rapidline can be made in the MK’s. The important values are in the “MK_TECHNOLIGIEDATEN1”, “MK_TECHNOLIGIEDATEN2”, “MK_TECHNOLIGIEDATEN3” and “MK_TECHNOLIGIEDATEN4”. Read the description in the bottom left box for each value that can be adjusted (Pic.4).
Pic.4
The most important values are:
MK_TECHNOLOGIEDATEN1:
Position 0, 1 and 2:
Position for manual cutting wheel change.
Position 3, 4 and 5:
Position for grinding wheel change.
Position 6,7 and Position 8,9:
Bridge position for transport in and transport out.
MK_TECHNOLOGIEDATEN2:
Position 0 and 1:
Offset between cutting wheel and glass edge sensor.
Position 6 and 7:
Offset between cutting wheel and toll measuring sensor.
MK_TECHNOLOGIEDATEN3:
Position 1 and 2:
X- and Y-Offset from the table zero point (edge of the felt) to the machine zero point (cutting wheel).
Position 2 and 3:
Position of the oil box.
Position 4 and 5:
Position for measuring the X zero point of the tool box.
Position 6 and 7:
Position for measuring the Y zero point of the tool box.
MK_TECHNOLOGIEDATEN4:
Position 0 to 7:
X- and Y-Offsets for each tool box (1 to 4) from the zero point of the tool changer.
