illegible.
- Only the settings described in these instructions are able to guarantee the correct operation of the controller.
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 controller conforms to the European RoHS directive 2002/95/EC regarding restrictions on the use of certain hazar-
dous substances in electrical and electronic equipment.
b
Never under any circumstances dispose of the controller with ordinary household refuse. Dispose of the controller
only at designated collection points or return it to the dealer or manufacturer.
