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:

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:
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.

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.

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.
