628.x Monitor: First can travelling time out of tolerance
Description
The first can body reaches the can-body sensor of the ejector more than one can-body length earlier or later than was measured in the setup. ("MaxAllowedDriftOnLarc2" parameter)
Remedy
- A monitor setup is required when production rate, can-body gap on conveyor belts, speed of conveyor belts or distance between welder and eject station is changed.
- Implement the new monitor setup (if necessary without energy, temperature, CalForce or powder monitor channel).
- With the OSS monitor: Perform new monitor setup. Disable dynamic OSS ejection, set parameter $LacquerMonitorOutsideEjectionDynamic=FALSE.
- The first can body in a series may not be removed manually.
- Check can-body detection (sensor or light barrier) in the eject station.
- When a monitor channel (energy, temperature, CalForce or power monitor channel) is active, an ejection unit must be selected in the options.
- Reset speed or transitions of conveyor belt.
- The following can be tried in old machines (FBB 400, FBB 5000, BWM, MWM, ABM) with can-body conveyor. In the setup, the can-body series should be large enough so the first can body reaches the ejection station. This setup procedure gives us the same conditions in the setup as in production. The setup can bodies do not have to be ejected.
