Problem:

Some Beckhoff i/o terminals are not active and status LEDs are off, control does not respond to commands.

Possible Causes & Resolutions:

  • The 24Vdc supply of the EK1100 coupler or the EL9410 intermediate supply terminal is missing or the voltage is too low > Check all connections, measure voltage, check fuses.
  • Bad contact between the terminals > Switch off the main power and remove the terminals. Clean the contact between the terminals.
  • Defective EL9410 intermediate supply terminal > Exchange terminal.
  • Defective EK1100 coupler > Exchange coupler.

 

 

 

Problem:

After main switch off and on again, HMI piece counter values and settings are lost or old recipes are loaded.

Possible Causes & Resolutions:

  • IPC has not shut down correctly.Check the IPC after you switched off the main switch: Normally it will continue to run for at least 30 seconds to shut down correctly. If LED’s of IPC goes off within a few second, the battery of the UPS – unit is dead and needs to be replaced.

 

Problem:

Suction cup malfunction.
Vacuum not working, constantly on or constantly blowing air instead of (sucking and then blowing) once only.

Possible Causes & Resolutions:

  • Most likely a relay is defective and needs to be replaced.
  • Vacuum suction injector is defective and needs to be replaced.

 

Components:

KA1.2-1.7 Relays

Y108 Vacuum blank feeder back
Y109 Vacuum blank feeder front
Y110 Vacuum 1.Table

Y111 Blow off blank feeder back
Y112 Blow off blank feeder front
Y113 Blow off 1.Table

Spare Part:

010482                        Vacuum suction injector        (Y109/Y112)

010486                        Vacuum suction injector (Y108/Y111, Y110/Y113)

Problem:

Drives start but the slitter does not start cutting in automatic mode. Pockets on sheet collector are full but stacks are not pushed out automatically and the button on the panel for pushing out manually does not work either.

Possible Causes & Resolutions:

  • Signal feeder active: Check the signal from feeder. When the feeder pick up the sheet stacks inside collector, the push out of new sheet stacks is blocked.

 

  • Reed switch B267 blank collector closed: If the blank collector is not closed, the function push out sheet stacks does not start. Check reed switch B267.

 

  • Light barrier B266 sheet stack in pick-up position: If this light barrier is damaged or not adjusted well, the function push out sheet stacks does not start.

 

  • Wrong setup for blank collector: If wrong type of blank collector is selected, push out of sheet stacks is disabled.

Problem:

The HMI cannot be started and the browser shows „NOT FOUND, The requested URL /en/default.htm was not found on this server“.

Possible Causes & Resolutions:

Not connected to Canman Wifi (only for wireless connected iPad’s): Check the wifi settings. Choose Canman wifi and try again.

IPC has not shut down correctly: In this case probably the HMI software can’t start up automatically by restarting the machine.

Check the IPC after you switched off the main switch: Normally it will continue to run for at least 30 seconds to shut down correctly. If LED’s of IPC goes off within a few second, the battery of the UPS – unit is dead and needs to be replaced.  Contact Canman for online support to restart HMI.

Problem:

First operation feeds the stripes too early into the upper magnetic belt of 2. table. Therefore the stripes do not stop on the upper magnetic belt and will be ejected through the slot in the frame of the 2. table.

Possible Causes & Resolutions:

Sensor B255: This sensor sends a signal to the control that the upper magnetic belt is ready for new stripes. The sensor might be defect or wrong adjusted.

Sensors B237 and B238: Sensor B237 does slow down the sheets and B238 stops the sheets for the centering. If the sheets do not stop, they may run through the first operation without being centered and with incorrect timing. The sensors might be defect or wrong adjusted.

 

Problem:

Everything looks fine but the drives do not start if the green button “Production On” is pressed.

Possible Causes & Resolutions:

The main power supply 72 VDC of the Linmot controller is missing:

Check the power supply G5 inside the control panel on the second table (see attached picture). Most probably the 15 Amp. fuse is melted. Replace the broken fuse with a new one.

Problem:

Error message „Magnet belt not down” displayed on HMI (magnet belt does only exist on the 2. table on a duplex slitter), and arrow buttons „Up” and „Down” for magnet belt are not visible anymore.

Possible Causes & Resolutions: 

Arrow buttons magnet belt up may be visible for a short time and pushed during start up of panel.
Delete of error message:

  1. Login with canman user => Contact CANMAN for password
  2. Go to Setup
  3. Change the function Single slitter to OFF (See attached picture)
  4. Go back to main screen. Now the up and down button for magnet belt will be visible.
  5. Push and hold the arrow button down for magnet belt until the error message “Magnet belt not down“ disappears.
  6. Go back to the canman settings and set the function “Single slitter” back to ON.

 

Problem:

  • Speed of the drives changes during production

 

Possible causes & resolutions:

  • Wrong position of the switch for the terminating resistor on the bus plug.
    Check all switches on the complete bus system. Follow the cable thoroughly from first DP bus device (PLC) to last DP bus device. The terminating resistor switch of first and last must be set to „ON”, all other to „OFF“.
  • Bus connector/plug defect
  • Check wiring of all profibus cables, especially the connection of the cable shield inside the plug.
  • Problem of terminating resistor supply by last device on bus. Try to change the profibus wiring to use on another device as last client.

 

The HMI of Can Man machines is optimized for an iPad, but as an alternative, a computer, laptop or another tablet with a browser can be used as well.
How to:
  1. Connect your device to the WLAN „CM_SMARTControl“. If you don’t have a Wi-Fi connection on your machine, connect a LAN cable to the router.
    Note: The Wi-Fi is password protected! Contact Can Man by opening a new ticket or ask your superior.
  2. Open the browser. Supported browser are Safari, Chrome or Firefox.
  3. Enter the correct IP address:
    Welder ➔ http://192.168.10.10
    Welding monitor ➔ http://192.168.10.11
    Slitter ➔ http://192.168.10.13
    Feeder ➔ http://192.168.10.15

Note: If you use a new iPad the icons for the machine type can be produced, when you tap on “Add to home screen“ button.

Problem:
Display shows „Could not activate iPad“

Possible causes & resolutions:

  • No internet connection > Check network connection of machine.
  • Firewall blocks connection to iPad > Try to connect the iPad to other Wifi without firewall, for example hot spot of mobile phone.
  • Try to make a reset by holding down the home and power button simultaneously for a few seconds until the Apple logo appears. Don’t worry, the iPad doesn’t have any data inside, it only displays the values from the browser. Can Man does not use an Apple ID to activate the iPad’s, so the iPad is resettable.
  • iPad might be defective > We will offer new one or you organize it locally.

For connecting an alternative display / PC, please have a look at the separate FAQ.

Battery of IPC is empty when:

  • System Date and Time (Error Log) not correctly displayed and getting lost when powering off the IPC.

 

To Do:

An overvoltage suppressor (or surge suppressor) is an appliance designed to protect electrical devices from voltage spikes. A surge suppressor attempts to regulate the voltage supplied to an electric device by either blocking or by shorting to ground voltages above a safe threshold.

These surge suppressors are built in to the latest Pacemaker models and machine controls (from 2009).

Check, if one or more modules of the surge suppressors are red/defect. Replace the red modules.

Attention!!!

Do not bridge the signalling contacts and run the machine with defective red modules because they no longer protect the system from voltage peaks!!!
If the modules are defective, check the main supply. Measure and check all voltages between the phases and all phases to earth before exchange the modules and restart the machine.

Preparing of LAN or WLAN access:

  1. Connect a new PC or laptop with the Wifi of the slitter (CM_POWER_CONTROL). If you don’t have the password, contact Can Man
  2. Open the network setting of that new device and set a fix IP address = 192.168.10.50 SubNet 255.255.255.0
  3. Transfer the “CanMan” folder (C:CanMan) with the programs from the original windows tablet to the new device

How to start panel/HMI software:

  1. Open the folder “CanMan”
  2. Open the folder “Runtime”
  3. Double click the file “WinGRS”
  4. Now the software starts and you can use it to control the slitter

Note: Panel Software is starting in Demo mode and does work for 60min only. After that it has to be restarted. To run the HMI without time limit you need a new license or if the original panel is not in use anymore the license can be transferred with the designated form:


Setting up of a new device in case of an unserviceable device:

  1. Ask Can Man for the HMI Software
  2. Unzip the received file to the desktop of the windows device
  3. Open the folder “CanMan”
  4. Open the folder “Runtime”
  5. Double click the file “WinGRS”
  6. Now the software starts and you can use it to control the slitter

! Attention ! The recipe from the unserviceable device is lost.

  1. Check the position of the switch!
  2. The internal battery is defect!

NOTE:
If you do not use the panel for a longer period (several weeks), the device should be turned off on the backside. Otherwise the internal battery will discharge and will get damaged!

 

NOTE:
The internal battery can be exchanged by opening the back cover of the unit. CM Article No. 009548

 

If you push the button on the right side, you are able to see the status of the integrated battery and optional available second battery.

 

The optional second battery is located at the back of the device.

 

Possible causes:

  • No supply of a slave on the bus system.
    • Check supply of all slaves.
      Emergency stop must be released.
  • Address of slave on Profibus is wrongly adjusted.
    • Check setting of all DIP switches on the Lenze bus module and on the Linmot controller.
      You can find the correct setting on the wiring diagram.
  • Wrong position of the switch for end resistant on the bus plug.
    • Check all switches on the complete bus system. Seriously follow the cable from PLC to the last slave. First plug and plug of last slave must be set to ON, all other plugs to OFF.

Possible causes:

  • Since the slider of the linear motor contains strong magnets, remove dust or small particles from slider with a disposable paper.
  • LED state shown by the yellow LED on the controller or check the hand panel
    • “Sensors / Actors 3/4”
  • Motor resistant according Linmot manual
  • Cable according Linmot manual

 

Possible cause:

  • wrong position of a reed sensor
    • check all reed sensors
    • use the help of the display – which shows the status of the sensors
    • consult the timing diagram of the PowerCUT – download here.

Possible cause:
– bus connector limit switch not set correctly – address and dip switches not set according

to the electrical scheme (bus subscriber) – wire defect
– bus connector defect
– bus modul or subscriber defect.

 

To narrow the error you have to check the status with all the subscribers.
To test, switch the limit switch into the bus connector => the bus runs now to the corresponding subscriber, e.g. “Lenze inverter” which the LED flashes yellow.

If you are able to narrow in the error, exchange the corresponding components.

 

NOTE:
Do not forget to set the parameter and the dip switches accordingly. The parameters are mentioned in the electrical scheme!

 

BF LED (red) not active

Lenze inverter:
LED upper-left must light up (green)
LED upper-right must be flashing (yellow)

LinMot:
Error LED not active or no error code profibus

 

 

Beckhoff Control:

For the Beckhoff Control, please refer to this PDF for instructions.

 

Please refer to “User Manual Motion Control Software” for the error codes of the MC Software. The PROFIBUS Interface has the following additional error codes:

Error code hexadecimal: Error description: C1h Fatal error: Drive not supported
C2h Config error: Invalid MACID
C3h DP Err: Connection lost
