iPad does not connect to the machine. Screen remains gray and shows no values.
Possible Causes & Resolutions:
Battery of IPC is empty when:
Reason for error message:
For a Pacemaker-repair we calculate / estimate a “cycle-time” of 2 weeks, including final testing and packing. If a faster service is required, extra charges occur. In case the number of incoming repair jobs is unusual high, it might take more than 2 weeks.
Note the adjustment of the clearance of the roller after the BIG8 monobloc cutting heads is ELEMENTARY to prevent bow cuts!
Check if the roller is not “tilted” (and thus one-sided “in the air”), refer also to manual of your slitter how to adjust the roller.

and how to access the PC in case of a trouble shooting.
What does this error message mean?
CCD = concurrent connected data variables.
The amount of active CCD is limited. Opening the HMI is using some of the available CCD.
Closing the HMI is releasing the CCD again.
When you repeatedly open and close the browser, the CCD can still be in use and getting into the limitation.
(There is a delay for releasing the CCD when closing the connection).
„If a client wants to subscribe to new data variables while no more CCDs are available, a message “CCD exceeded!” will appear and there will be no communication with these data variables.“
„If a client disconnects from the visu (e.g. browser gets closed), it will take some time until the browser session expires and the CCDs from this client become available once again (session timeout of the scada server: 2 min.).
How to solve a CCD exceeded?
Close alle open browser connection and wait for >2 min.
Now you should be able to open the HMI without error message.
How to prevent a CCD exceeded?
Don’t open the HMI in several browser simultaneously.
Don’t repeatedly open and close the HMI in short time.
Don’t repeatedly press reload the HMI in short time.
The decrement counter shows the number of cans between the welding station and first light barrier of the eject station. If the value is wrong, the ejection of cans is out of sync with the faulty products.
The decrement counter is not stable, which leads to continuously smaller values during full production.
Possible Causes & Resolutions:
Because of the 87 Hz technology. Read more about it here.
IMPORTANT: The inverter parameter setting must be exactly same like before (original setting). Otherwise motor will burn!
Reference for thickness of the welding seam is related to thickness of material (this value is variable, depending on the overlap of the welding seam, material as hardness and tin coating, welding pressure, welding current and welding frequency).
T = S x 1.75
T = thickness of the welding seam
S = thickness of tin plate
T = 0.15 x1.75 = 0.2625 mm
Necking tool tolerance
D = S+W+L+P+E (mm)
D = difference between inside/outside diameter of necking tool
S = thickness of tin plate
W = thickness of welding seam measured by micrometer (we should measure beginning, middle and end of the welding seam)
L = thickness of outside lacquer stripe 0,02 mm
P = thickness of inside powder stripe 0,07 mm
E = extra space (0.05 mm)
D = 0.15 + 0.26 + 0,02 + 0,07 + 0.05 = 0.55 mm
S = 0.15 mm / W = 0.26 mm / L = 0,02 mm / P = 0,07 mm / E = 0.05 mm
We recommend following maintenance procedures:
Safety data sheets see below:
NOTE: In case you have to replace the converter, make sure you load the default parameter setting. All the latest models, do have the parameter setting in the electrical scheme – if you do not have the parameter, contact Can Man by filling out a ticket in the support section on our website.
The upper pendulum roller might be not leveled properly. When regrooving the upper disc for example 0.50 mm in diameter, the height of the pendulum rollerhead must be reduced 0.25 mm. This can be done by the M10 screw on the back side.
See also in the manual X1 how to reset the upper pendulum rollerhead.
NOTE: The description manual is based on a CM X1 welder, but it works very similar for our other welders.
ATTENTION: Do not touch the red marked screws!
Your cooling system has to be checked and / or one or more circuits need to be cleaned.
If the temperature difference exceeds a certain value, mechanical mis-alignments may occur which can affect the welding geometry. Obviously it is not the same when a welder is cold (start of production) and hot (after up to1h of production).
NOTE: With Can Man TempGUARD™ system, this can not happen anymore.
If you still couldn’t resolve the problem, read more here.
The gap between the cans is not constant (see picture below).
See also following FAQ-article Why can’t I keep the distance from can to can constant?
Please note that those are minimum heights!
For more detailed dimensions, see products page > technical data > Layouts
NOTE: Make sure that the wire is not touching anywhere. Only a perfectly set and maintained canbody welder, can assure perfect welding! A weld monitor is a pure “measuring instrument”.
Check this specific wire crossing (red arrow). The wire might touch each other here!
Check the connection from the voltage pickup to the Qualimaker board.
The actual value of the weld power limiter increases with the heating of the machine.
Readjust the weld power limiter, to a higher value. Observe the “Max” value from a “cold “ start to a “warm up” machine during production. See also note below.
DO NOT ATTEMPT TO SWITCH “ON” THE CURRENT ANYMORE!
Further attempts to switch on the current, can destroy or damage the semiconductors (IGBT) in the Pacemaker!
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 (from 2009).
Check, if one or more plugs of the surge suppressors are red/defect. Replace the red plugs.

Possible problems, if the overlap function does not work!
The Pacemaker™ static welding inverter has a RAM battery for data retention and clock-buffering at power interruption/disconnection. The battery has a limited life span (about 5 years) that decreases especially without power supply (controller off). To prevent loss of data, the battery must be replaced early enough.
The parts can be ordered in our webshop or with prepared form.
Using a handpanel:
When you start up your Pacemaker, the software version will be displayed during the boot process.
Alternatively the information will we displayed, when you press the key “down” several times until you get to “Info Version”: e.g. 5.27
Using a CM16 welder you will also find the info by pressing the key “down”, since the display is the same as the handpanel of a PM.
Using a X1 welder:
Tip on the *eye” icon and the Pacemaker software version is displayed on the bottom line.
Using X8 welder:
Tip on the “eye” icon and then on a second “eye” icon to get to software version info on the bottom line – check also your manual book 1 – chapter 4.6. how to find the info.

NOTE: The reason for the low current is due to an open circuit. The wire might be also hot in this case. If you have in general a high power percentage you might reduce the frequency.
Scroll down in the display menu until you reach the temperature display. Observe, if after crossing the switching threshold, the temperature doesn’t change, that the solenoid valve is blocked (when the 2nd thresholds are reached the message “over- or undertemperature” will be displayed).
NOTE: The error message “Ths too low (Ths = Temperature Heatsink)” might be an indication for a contaminated valve.
The Pacemaker has the following options to connect the output of the weld power limiter to other systems/controls (i.e. can rejection control):
Possible reason choke coil defective
If the voltage value drops below 350 V the error message “Phase voltage error” shows up.
Check the main supply: L1 / L2 / L3.
Check also the input directly inside the PM.
QM board defect?
A reason for a voltage error could also be a defect on the QM board, which receives it’s supply from the elec. board of the PM.
To verify a defect you can remove the supply cable. The voltage value should go up around 20V (e.g. 375V to 395V), which is normal. If the increase much bigger than 20V the QM board has a defect and need to be replaced.
As a matter of fact, this electrical balancing of the two values has been done by CANMAN prior to the delivery. If there is a discrepancy you can adjust it.
You have to lose the small electronic board of Qualimaker (if applicable). This board is supplied by the big electronic board of PM. If you remove this supply cable, the voltage value goes up around 20V (e.g. 365V to 385V), which is normal.
Now measure the input of terminals, for example 385V. Turn the small blue potentiometer (picture). Control the value on touch screen. Must be around 20V more than the measured value, if you have a QM board. If you have adjusted it, connect the supply of QM and now you have the correct value on touch screen.
Starting with the version of the V4 mainboard, the board has two potentiometers. You need to adjust the “UMains” potentiometer in this case.
FAQ – Trouble Shooting
– Check the cooling-water-inlet.
– Check the “Ths” and “Tamb” on the display.
– Check the small fans of the Pacemaker
The error “Ths too low” means temperature heat sink (copperplate) too low. If the copper plate is too cold. It can damage the
