Important requirements:

t2 must be always higher than t1 (t2 > t1).
t2 and t1 must be set lower than 1 cycle time of the machine. For example, if the machine is running with 300 cans/min the cycle time is 200ms. Therefore, t2 and t1 must be set lower than 200ms.
To do an overlap check set “overlap check” to “ON”. The reduced current will be set automatically to 0A. In the same window you have an additional value. If you set this for example to 10ms you have more unwelded area at the beginning and end of can.
NOTE: If you use “overlap check” function is not necessary to switch “Ired” to “ON”.

Possible problems, if the overlap function does not work!

If you can’t see the value t2 and t1, maybe the pacemaker is running with “Old” mode and not with “CMX” mode. Change in the setup “CT” from “Old” to “CMX”.
No input signal on input 4 (terminal 7 and 8 on pacemaker board). If machine is running, LED behind input 4 (clamp 7 and 8) must flashing. This is the cycle signal to start the timer t2 and t1 for the overlap check.

Possible Cause (CM16 / S, X8):

Check air supply for the cylinder.
Eject cylinder must push the canbodies inthe center, the can must move verticallyaway from eject cylinder.
Second light barrier is always ON.Sensor dirty or bad adjustment.
LED on light barrier must be ON without can, OFF if a can is detected.
Control wiring of first and second light barrier according electrical diagram.
Make sure the faulty can is really ejected, means does not touch the edge of the bin and jumps back.
=> Use a fixed channel underneath the eject station, instead of a mobile bin!

Adjustment of the light barrier distance to eject cylinder might be wrong.

Wrong adjustment of the transport belt speed.

NOTE:
The ejected can should whether touch the can before nor the following.

Eject pulse cylinder has to fit to production speed:

Recommendation: 150-200msfor<100cpm 100-150msfor100-200cpm

80-100msfor200-400cpm

Place a canbody between the second light barrier and check the LED „LD3“ on the eject print (inside the Pacemaker).
Must be „ON“.

The autoreset needs to be “OFF”. Therefore the can memory will not be reset automatically.

Check, if your hardware parameters are set correctly, according to one of the three layouts.
=> See layouts below!

Possible Cause (Pacemaker):

Check air supply for the cylinder.
Second light barrier is always ON.
Sensor dirty or bad adjustment.
LED on light barrier must be ON without can, OFF if a can is detected.
Adjustment of the light barrier distance to eject cylinder might be wrong.
Wrong adjustment of the transport belt speed.
