025  Overlap check!

Important requirements:

1.  t2 must be always higher than t1 (t2 > t1).
2.  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.
3. 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.
