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.

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.

Problem:

iPad does not connect to the machine. Screen remains gray and shows no values.

Possible Causes & Resolutions:

  • Connection via Wi-Fi
    • In the settings, check whether the iPad has connected to the correct Can Man Wi-Fi
    • If no Can Man Wi-Fi is visible, check router/wireless access point.
      ➔ Restart router/wireless access point. If still no Can Man Wi-Fi is visible, the router/wireless access point has lost the settings or is broken. Contact Can Man via by opening a new ticket.
  • Connection via Cable
    • Check all plug connections of the network cable between IPC and iPad
    • Check iPad adapter power supply. The adapter must always be powered, otherwise the connection will not work.

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.

NOTE:
The Rexroth drive has absolute encoders, therefore a battery is necessary to back-up the encoder signals. If the battery is low you will receive an error message.
Exchange the battery, according to the Rexroth manual.

NOTE:
In case the position is lost you need to reset to the reference point, you will find instructions in the Rexroth manual.

 

ATTENTION:
Do not switch off the machine when you exchange the battery, otherwise the position gets lost.

NOTE:
The impact of this problem could mean PLC might switch to stop, and the centering column will lower itself.

 

Check the wiring of the holding magnet for a short circuit.

 

Exchange the relay of the magnet control. Refer to the electrical scheme and picture below.

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.
