Machine:
The experiments were carried out on an industrial Throughput Parts Cleaning Machine (TPCM) at the ETA factory.
The machine is equipped with power measurements (1 Hz) on electrical component level. The Dataset contains 1 min averaged data of sensor and control values.


Experimental series:
To induce different concept drifts for validation, we performed a series of different production tasks on the machine. 
The target schedule for all production days started with heating up at 8:00 followed by operation from 8:30-11:30 and from 12:30-16:00. 
All tasks were conducted in continuous operation mode with typical process parameters, but no parts were conveyed through the system as process results were not subject of interest. 
During the experiments, we used the following tasks and process parameters:
- Reference: Target temperature for the aqueous detergent is 50 â—¦C for both tanks. Target temperature of the drying air is 70 â—¦C. Fan speed is 870 rpm for all fans.
- Increased fan speed: All parameters stay the same as in reference except of an adjusted fan speed of 3000 rpm.
- Increased drying temperature: All parameters stay the same as in reference except of an adjusted target temperature for the drying air of 60 â—¦C.
- Increased tank temperature: All parameters stay the same as in reference except of an adjusted target temperature for the tanks of 60 â—¦C.
- Infrared drying: All parameters stay the same as in reference except of infrared drying is used instead of the electrical air heater.
