Error 105.x Monitor: too few samples
Description
The number of measuring points between two machine cycle pulses has changed excessively while production is in progress. Deviation >6%
This monitoring is used to remind the operator to do a new calibration after the production speed or the frequency has changed.
But a more important reason is: That the fault is triggered if the machine cycle signal is faulty.
- If during one machine cycle two or more clock pulses appeared. In this case the monitor gets out of synchronization and start rejecting the wrong cans.
- If one machine cycle is missing.
Remedy
- After every change of the production parameters (welding frequency or production rate), calibrate the monitor again.
- If the contamination signal of the welding current source is faulty, check wiring and rectify the fault.
- If machine cycle signal coincides with the can-body leading end, adjust position of switching disk by a few degrees.
- In the event of fluctuations in the welding current frequency, measure the welding current frequency.
- If the machine cycle signal is faulty, test machine cycle sensor and current path.
