Problem:

The push fingers to feed the stripes into the 2. operation do not work  or do not always work properly and no error message appears.

Possible Causes & Resolutions:

• The stripes must slide flat on the table at all times so that they are correctly detected by the sensors B260 and B261 that trigger the Linmot pusher. See the pictures below where the sensors B260 and B261 are located on the newer and the older slitter type.

• Clean the senors B260 and B261. Metallic dust can lead to malfunctions.

• Check the height of trigger sensors B260 and B261. If they are set too low they can not detect the stripes properly.
• Check the spring load of push fingers. If the spring load is set to high, the stripes can be lifted up if they pass the fingers and this can create detection issues for the trigger sensors B260 and B261. Adjust the spring tension so that the push fingers return reliably to the upper position but with as little pressure as possible.
• Gap between stripes is too low. The push fingers need time to return to the initial position. If the gap between the stripes is too small, the push fingers may not yet be ready to feed the next stripe. Check the value of stripe width on HMI. Is it set correctly?
• Defective trigger sensor or sensor cable B260 and B261.
• Defective linmot controller U26. Check linmot controller for error message. Contact CanMan.

Problem:

The sheet is lifted by the front sucker bar but then dropped instead of being pushed into table 1. After 3 times slitter stop and error message “SEPARATION: Double sheet counter limit” appears.

Possible Causes & Resolutions:

• Check on the HMI whether the correct sheet thickness values has been set.
• Check whether the sheets are sticking to each other or not. If they do, separate the top ones physically from each other and try again to destack them.
• Check the position / correct function of all separation air nozzles left and right: The top sheets should be visually separated.
• Check the position / correct function of all separation magnets left and right: The top sheets should be visually separated.
• If available switch on the separating air between downstacker and 1. table as well, and reset their height if necessary.
• Check the physical setting height of the double sheet sensor: If the sensor is set too high, he will not be in contact with the sheet, resulting in incorrect measurements.
• Check the cable between double sheet sensor and control. There may be a cable break which influences the measurement result. Replace the cable if needed.

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:

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.

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)

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.
