Possible solutions:

• Measure the cutting tolerances of at least one complete sheet:
  Is the diameter within tolerance ?
  Is the height within tolerance ?
  Is the angularity within tolerance ?

• Are there any burrs on diameter / height cut ? If yes, sharpen and reset the knifes first. Adjust the clearance between the knifes acc. manual.
• Are the width of both trims correct (min. 2mm) ?
• Measure the overlap of all Big8 knifes with the respective gauge:
  Target is 0.13 – 0.15 mm
• Make sure that the corners of the stripes are not damaged (before entering into the Big8 unit)
• Check the side centering system before 2nd operation: Is it correctly set ?
• Remove the trim guides, check them for any damages, and re-install them again:
  The gap between guide and top knife shall be around 0.2 mm.
• Make sure all transport rings are in good condition and correct positioned.
• Check the drive system of the Big8 unit:
  Is there any damage on the drive system and is the timing belt well tensioned ?
• Check the upper rubber / lower steel roller system after the Big8 (no direct impact):
  Is there any damage ? Is the gap between both rollers correctly set ?

Possible Causes & Resolutions:

• Check the blank cutting tolerances and quality (download form for cutting tolerances): If the cutting measures are out tolerance, blanks will create downstacking and double sheet errors.
• Check the burrs on the blanks (Cutting burrs B max. 0.15 x sheet thickness s): If the burrs are too big, the blanks will create downstacking and double sheet errors.

• Check the general setting of the blank magazine acc. instruction manual. The separator notches should always be aligned with the suction cups.
• Check the separating air: If the separating air pressure is too high or tool low, the bottom blanks will not being separared correctly. Try with more or less separating air.
• Check the position of the separation air nozzles: The air shall always being directed towards the most fanned-out part of the sheet stack. The distance between the separation air nozzles and the sheet stack should be a maximum of 1mm.
• The top position of the suction cup should always be adjusted with the separation air turned on to prevent it from being set too high. Otherwise the separating air between the sheets is pressed out which will lead to double sheets.

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:

Problem:

Circuit breaker Q5 trips when the machine is switched on or during production.

Possible Causes or Resolutions:

• Measure voltages at all phases, even under load. It is possible that one phase did drop down, and this triggered the circuit breaker.
• Measure the current of each phase with a current clamp after Q5. If the measured value is below the value of the circuit breaker and Q5 still keeps tripping, the circuit breaker may be defective. Replace it.
• Maybe the parameter “Low bat voltage” (coming from Pacemaker) is set too low: That means that the contactor in the Pacemaker closes too early with a precharge voltage that is too low and therefore Q5 trips. To check this, please open a ticket to contact CanMan.

Problem:

Homing for the drawer pull-out system is not executed or stops and error message “Automatic Homing Failed” appears.

Possible Causes & Resolutions:

• Check the light barrier in front of the drawers. It must be ensured that the sensor above has a direct line of sight to the reflector below. If necessary, realign and check that all screws of the holder are tightened.

Problem:

All drives are starting correctly, but the vacuum and welding current are not active.

Possible Causes & Resolutions:

• Welding pressure has been set below the min. value of 2.0 bar => Check the welding pressure setting value on the precise air-regulator and reset if needed.
• Solenoid valve welding pressure Y10 does not work correctly  => Check the welding pressure valve Y10. Does the valve switch correctly and do the welding rollers close?
• Welding rollers are closing and welding pressure is set correct, but no welding pressure value is displayed on the HMI => Check whether the analogue sensor B77 is working correctly or not.

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:

• Welding process starts but welding current is not constant. Finally the welding wire breaks.

Possible Causes & Resolutions:

• Bad condition of the lower welding roller or upper roller head. In this case, the current only flows through the welding wire and no longer over the welding roller or upper roller head. The welding wire heats up and breaks. Exchange lower welding roller. If the problem still exists, replace the upper roller head.

Reason for error message:

• The Pacemaker™  capacitor bank voltage is to low.

Possible causes:

• Supply voltage mains drop down. Please check all phases even when the machine is running. Does a phase drop down?
• Check complete wiring, Are all clamps tightened?
• Check the 24Vdc supply terminals 17/18 on Pacemaker board. This 24Vdc are supplied by the welding machine and has to be always on. If the 24Vdc is missing, the precharging of capacitors works, but the main contactor will not switch on => Ubatt Error

• Check the 24Vdc output terminals 41/42. After precharging is complete, 24DC should be applied here to close the main contactor. Possibly the small print relay on the electronics board is defective.

Problem:

PowerCURE display shows error message “E-Stop remote”

Possible Causes & Resolutions:

• One of the overcurrent motor protection relays Q27 for the fan exhaust has tripped.
  Check the fans for lacquer residue. Can the fan rotate freely? Not blocked by lacquer?
• Inverter for bridging conveyor is in error state. Check the belts. Free of lacquer? Check motor.
• Inverter of conveyor is in error state. Check the conveyor belts. Check motor.

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:

During production, the error message “over temperature upper current conductor” appears. This means that the cooling is no longer sufficient to keep the upper current conductor constantly below 40 degrees Celsius.

Possible Causes & Resolutions:

If the cooling unit is working properly (temperature and pressure is OK) and no flow switches are giving an error, then contamination is most likely the cause of the problem.

Clean the cooling circuit, especially the cold-water circuit in this case, including the cooling unit. Check the water level in the cooling unit and top up if necessary and replace lubricant (if PowerROLL – coolant or DISCON is used) and clean the cooling system as recommended every 6 months.

Problem:

Downstacker motor doesn’t move correctly to the reference position, stops or suddenly changes the direction of rotation. Display of servo controller U16 shows „IMax“ or „P03 trip“.

Possible Causes & Resolutions:

To check:

• Mechanical condition of downstacker motor: Turn it by hand and check that everything runs smoothly.
• Resolver mounting: Is firmly connected to the motor shaft?
• Resolver bearings: Remove the resolver from the motor shaft and check if it is turning smoothly.
• Resolver and motor connections: Motor and resolver are connected correctly and clamps/plugs tightened?
• Motor windings: Disconnect the motor from the inverter and check the windings with an ohm meter (U-V,U-W,V-W). All values are equal?
• Output servo controller: Measure the inverter output voltage when it should run (U-V,U-W,V-W). If 0V and display shows „IMax“ maybe servo controller defective.

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.

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:

Machine stops and message „Pacemaker: Profibus communication error“ is displayed.

Possible Causes & Resolutions:

• Cooling water valve: Wrong type of valve or plug without protective circuit (suppressor). The voltage peaks can cause interferences in the Pacemaker electronics. Always use the original plug and valve type.
• Profibus plug: On the plug of first and last client of profibus system the termination resistant must be set to ON. Otherwise interference may occur.
• Profibus cables: Check the position of the cables in the control unit. If they are close to contactors, high voltage peaks can create interferences.

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:

Graph remains grey and shows no curves at all.

Possible Causes & Resolutions:

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.

Possible reason:

• Check the blank cutting tolerances (can be supplied by Can Man): If the cutting tolerances are to big, the blanks will create all kind of downstacking errors.
• Check the burrs on the blank: If the burrs are to big, the blanks will create all kind of downstacking errors.
• Check the setting of the separating air: If the separating air is to low, the blanks can not being pulled down correctly. Try with more or less separating air.
• Clean the slider of the Linmot pusher according the manual.
• Magnets in the base plate might brake the blanks to much: Can Man does equip each base plate with 4 or max 6 magnets, depending on the the blank size. Remove eventually 2 magnets.
• Check the clearance of the first rollformer roller pair: The clearance between the lower and upper roller might be too small. Adjust the value according manual.
• Check the “Quick Change Level 40mm” setting acc. below pictures on the HMI: If the distance between the blank stack and the base plate measures 30 mm, set the function “Quick Change Level 40mm”  to OFF. If you measure 40mm, set it to ON.

• Check the vacuum-stop point: The process to stop the vacuum must be activated by the mechanism around 3 mm before the blank arrives at the base plate. Please check the manual how to set.
• Check if the supporting air-pressure to stop the vacuum is adjusted correctly: Check the value / setting according the manual.

Problem:

Canbody transport motor doesn’t move correctly to the reference position, or stops, or changes the direction of rotation, or the display of the servo controller U7 shows „IMax“ or „P03 trip“.

Possible Causes & Resolutions:

To check:

• Mechanical condition of canbody transport motor: Turn it by hand and check that everything runs smoothly.
• Resolver mounting: Is firmly connected to the motor shaft?
• Resolver bearings: Remove the resolver from the motor shaft and check if it is turning smoothly.
• Resolver and motor connections: Motor and resolver are connected correctly and clamps/plugs tightened?
• Motor windings: Disconnect the motor from the inverter and check the windings with an ohm meter (U-V,U-W,V-W). All values are equal?
• Output servo controller: Measure the inverter output voltage when it should run (U-V,U-W,V-W). If 0V and display shows „IMax“ maybe servo controller defective.

• Machines with lift table and non-stop: Check whether the white gear wheel on the encoder shaft of the downstacker motor is fixed on the shaft by the M3 grub screw. Make sure that the grub screw is aligned to the flat surface on the shaft.

Problem:

• Welding process starts but no welding current.

Possible Causes & Resolutions:

• Condition of lower welding roll: Possibly the roll is worn out or mercury very old. Refill mercury or exchange lower welding roll.
• Condition of upper roller head: Possibly the roller head is worn out or mercury very old. Refill mercury or exchange upper roller head.
• Waterflow: The green button for welding current on/off must light up when the water flow is ok. If not maybe the water flow is to low. Check also the relay K21. If water flow is ok this relay has to be on.
• Welding pressure switch S31: If welding rolls are closed the switch S31 do enable the welding current. If the welding pressure is adjusted to low or also to high the control do not enable the current. Do adjust the welding pressure correctly according manual.
• All connections of current conductors on secondary side of welding transformer: All screws must be tightened. If there are signs of corrosion, disassemble parts and clean the contact surfaces.
• Connection between head piece and lower welding arm: Remove the head piece and check the contact surfaces.

• Fine-wire fuses F2, F3 and F4: This are located inside control. Check them with ohm meter and replace if necessary.
• Transformer T4 (18-0-18V): Measure the outputs of small transformer inside control. The easiest way to do this is to measure it at the terminals of the WEC card. c32/c30 => 18VAC, c32/c28 => 18VAC, c28/c30 => 36VAC
• WEC electronic card: Firmly inserted in the card holder?
• Thyristor: Maybe thyristor module is broken.

Problem:

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

Possible Causes & Resolution:

Excel Spreadsheet – CM Electrical Components List

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.

Please consider the following suppliers for various raw materials:

Raw Material Suppliers

Copper Wire Suppliers

Please follow the below instructions carefully:

1. Cooling unit for cold water (for both welding rollers):

• The cooling emulsion must be changed yearly, but more preferably every 6 months. 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 !

2. 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 !

3. 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.

4. 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 !

5. 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:

6. Other possible errors:

• If the copper wire gets burned, check if the upper and lower weld roll are touching each other without a blank between. Press the button on the main-aluminium plate to close the welding roller and test it.

11. Double check all connection before switching on the main power.
12. Compare the settings/parameter and change it if necessary. For instructions which parameters has to set and how to do please contact Can Man
13. Re-start the PowerCURE™

Problem:

• Welding process does not start or starts too early before the welding rollers are closed and burns a hole in the can.

Possible Cause:

• Wrong signal of welding pressure switch. The start of welding current and transport is activated by a digital pressure switch S31 installed on the air regulator for welding pressure. If the welding rolls close and the digital pressure switch reach the programmed value the welding does start.

Check:

• Is the setting of welding pressure correct?
• Does the welding pressure cylinder work fine? Does it open and close smoothly?
• Does the welding pressure switch work properly? The switch must switch on when the welding pressure is between 1.5 and 3.0 bar.

Question

How are the blank cutting tolerances?

Resolution

Please check the PDF Blank Calculations and Tolerances

Important things to know:

• One canbody cycle = 0 – 360 °
• “Mclk Sync Deg” stands for Machine clock synchronization (in °). You can shift the clock/cycle signal (0-360 °) in order to get a proper synchronization of the graph to the measured canbody.
  • A smaller value will shift the graph to the left,
  • a bigger value to the right.

1. Problem:

The graph is not showing any values / no picture at all.

Possible Causes & Resolutions:

• The first parameter “Mclk Sync Degree” has a “dead area”, where the tool sensor detected the gap between the two cans, rather than the cans. As a result, there might be no graph showing. No graph showing means the system is not detecting that a can was welded.
  ➔ If no graph is shown, try to enter values in large steps. You should now see a graph but might have to adjust the measured area. Please see second problem for the resolution.

2. Problem:

The graph of the G-Sensor does not show a steady graph but shows greater fluctuations (= can gap).

Possible Causes & Resolutions:

• The G-Sensor is not correctly installed and measures outside the canbody cycle.
  ➔ In order to remove the greater fluctuations out of the graph-frame, increase the “Mclk Sync Degree” value to shift the graph to the right, and decrease the value to shift the graph to the left.
  Example: Your graph looks like the left picture below. You will have to decrease your value by about 40° in order to receive a graph like on the right.E.g. you have a value of 180° and have to decrease by 40° = enter 140° OR you have a value of 20° and have to decrease by 40° = enter 340° (canbody cycle goes from 0-360°)

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.

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)

Reason for error message:

• The Pacemaker™ HF has detected a missing phase.

Possible causes:

• Supply voltage mains (all three phases) 400V
• Check the small fuses on the bottom of Pacemaker HF
• Check complete wiring, Are all clamps tightened?
• Measuring voltage at the input terminals on the main board (see attached picture)
• IC “OC14” or phase measurement is defective. Replace the IC, Type HCPL3700
