2.9 Power Class
The "Power Class" considers the country-specific heating output versions of the machine, the connection configuration at the grid power terminal, and the cur-
rent protection on the supply grid side. The Power Class is therefore useful for optimizing utilization and ensuring machine functionality.
The Power Class determines the following:
Mutual lockout and enabling of components such as the grinder and heater.
Lockout and enabling of parallel product dispensing(ensures optimal utilization of steam pressure and thus of dispensing temperatures).
Heating and reheating thresholds based on heat output
Important note for technicians:
Therefore, the software-adjustable Power Class MUST always match the rating plate indication.
If this is not adhered to, then errors specific to the heating time, for example, or undesired deviations (temperature fluctuations ...) in the beverages can occur.
In the worst case, this can trip a customer’s on-site circuit protector.
The "Power Class" that applies to a machine is on the rating plate.
Important note for technicians:
After replacing the operating panel, replacing the plug-in board/SD card, or after Factory->Service/Customer (resetting to factory standards, the Power Class
MUST be read from the type plate and entered again.
