ABOUT THE CONTROLLER
The MFWC controller enables efficient use and operational control of the mixer system. For each of the single setting
procedures, the keys are assigned to specific functions and explained.
The controller menu contains key words for the measured values and settings, as well as help texts and graphs.
Main features of the MFWC controller:
- Backlit display showing text and graphic content
- Simple viewing of current measurement values
- Analysis and monitoring of the system by means of statistical graphs, etc.
- Extensive setting menus with explanations
- Menu lock: activated to prevent unintentional alteration of settings
- Function allowing restoration of previously selected values or factory settings
- Wide range of additional functions.
DISPOSAL
The unit conforms to the European RoHS directive 2011/65/EU for the restriction of the use of certain hazardous substanc-
es in electrical and electronic equipment.
b
The unit must not under any circumstances be disposed of with ordinary household refuse. Dispose of the unit only
