Warning
Description of initial operation
1. Before switching on the mains, check the correct assembly and electric connection.
Initial operation may be performed only by qualified expert personnel!
Note
Specific settings and functions of the MFC are described in this device description. Additionally to
this notice, the device documentation MFC and FCS are to be noted.
Set the address code
The same address code must be set at the assigned transmitting modules as well.
The device is delivered with the setting “000”.
Warning
Training with the MFA and the corresponding field device takes place automatically with the first regularly
received radio telegram.
Please observe possibly delayed data transmission due to the transmission interval of a radio path!
Note
Radio communication in the 868 MHz frequency band is not maintained permanently, but is subject
to a legally determined relationship between transmission period and transmission pause ("duty
cycle").
When the radio communication is interrupted, the connected drives are set in a security position.
The valves are then opened to 30%.
Note
The reception of a valid radio telegram resets this function.
The red error LED at the FCE turns off.
