Problem:

  • HMI communication error (see picture)
  • Not able to run the welder

IMG-20201111-WA0070.jpeg

 

Possible Causes & Resolution:

  • Turn the machine off and back on and see if the error message comes up again.
  • Check for the LED “on” at the PLC.
  • The machine isn’t showing any reaction (for example wire manual)
  • Please check the MPI-bus connection between the touch panel and the PLC.
  • Also check if all the PLC modules are properly mounted to the c-rail.
  • The machine was switched off for a longer period.
  • The PLC has an internal battery. To be sure that it can be sufficient charged, leave the machine power on for >24 hours.
  • Change the battery of the Pacemaker, see FAQ PM send error / PM receive error or welding parameter don’t match after starting the machine.
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.

Please follow the below instructions carefully:

  1. Cooling unit for cold water (for both welding rollers):
  • The cooling emulsion must be changed yearly. Follow the X7 manual if you have to change the emulsion !
  • The filter cartridge of 50 µm needs to be replaced monthly ! Follow the X7 manual if you have to the filter cartridge !
  • Check the level of the cooling emulsion on the internal tank. If you have to refill the tank, follow the X7 manual to get the correct mixing ratio for the emulsion, and fill the tank. Note: If the water level is too low, the chiller should show an error message, and the X7 should stop and show an error on the iPad !

 

  1. Cooling water / emulsion distribution station on X7:
  • Run some (5 to 10) can bodies and control the water pressure on the manometer: 5.0 bar is the min. required water pressure !
  • Run some (5 to 10) can bodies and control the water flow on the flowmeter S26 (2. From right side): 5.0 liter per minute is the min. water flow.
  • Note: The water pressure switch S120 is set to > 4.0 bar. If there is the error message “Error S120” on the iPad , first check the water pressure on the manometer, and if it’s below 4.0 bar check the cooling unit again !

 

  1. Weld roll ø 42 / 49 / 54 / 62 / 90 mm and lower weld arm:
  • It’s possible that the cooling circuit from waterflow meter S26 to lower weld roll, and back to the outlet on the water distribution, is blocked:

Take off the lower weld roll, unplug the grey water tube ø 10 mm labeled with “àWR” directly at the flow switch S26, and blow into the tube with air pressure. Check the out-going air-pressure at the free hole in the lower weld arm (supply for lower weld roll). If the circuit is free, you feel an equal air pressure (like on the output of the air gun) on your finger tip. If you recently took off the lower weld arm, there might be a problem with one or both o-ring seals between arm and upper bus bar:

Please check them if needed !

  • Now unplug the grey tube ø 10 labeled with “WR à” on the water distribution and blow into the tube with air pressure. Check the out-going air-pressure at the free hole in the lower weld arm (exit of lower weld roll). If the circuit is free, you feel an equal air pressure on your finger tip
  • If you re-install the lower weld roll again, make sure that the arrow “running / turning direction” is showing into the right direction.

Before re-connecting both grey tubes ø 10 mm, blow into one tube again by air-pressure, and feel the equal air-pressure on the other tube by your finger tip. If it’s ok, correctly connect both tubes again.

 

  1. Copper wire / copper wire profiling unit:
  • Measure the copper wire profile after the profiling unit on various positions (within around 300 mm). Check the correct width in the X7 manual. The tolerance must be within 0.03 mm !
  • Please check if the wire guiding wheel in front of the lower weld roll is broken. If it’s broken, replace it by a new one. Make sure you choose the correct size 1.90 or 2.30 mm !
  • Please check if the copper wire tension is correct. Set the correct tension according X7 manual !

 

  1. Welding parameters:
  • Please check the weld pressure. Set the correct welding pressure according X7 manual. The range should be between 40 and 50 daN.
  • Please check the welding frequency. Set the correct value according the recommendation in the iPad !
  • Please check the welding overlap. The welded overlap should be nosepiece overlap + 0.1 mm !
  • Check if the IR-Sensor graph of the Qualimaker 2™ on the iPad are within the correct range and straight, which means that the crown and exit conveyor settings are correct:
