Support

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.

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:

• Replace IPC battery with Lithium Battery Type CR 2032
• Replace battery according to the Beckhoff Instruction (Access to Battery)

Possible cause:

• Check if the voltage pick – up “tongues” are worn.
• Check if there’s enough “contact pressure” of those tongues
• If they are bent; change them, do not attempt to bend them yourself, they might break!

Cause may be a short. Make sure that the bracket of the IR-sensor is complete isolated. No bolts etc. should touch the rocker arm or other parts.
