Device Description Multi radio connection MFA
Application
The Multi-Radio Connection MFA provides the indirect activation of wireless
control of conventional, mains-driven continuous small servo drives. Within the
signal chain the MFA works as a radio converter.
In radio networks it represents the interface between wireless signal paths and
line-dependent activation.
The voltage supply of the MFA is an integrated switching power supply unit
which permits the power supply on the secondary side for a maximum of two
continuous small servo drives of the types M25Y or M15Y-S2.

Multi radio connection MFA Device Description
Assembly
General installation notes
Devices communicating via radio can not always be assembled at arbitrary locations, as wireless data
transmission is more or less strongly influenced by the constructional and spatial conditions.
Prior to installation and assembly, therefore, the building structures must be analyzed and a series of
measurements must be carried out to determine the specific ranges inside the building. A corresponding Kieback
& Peter service and diagnosis tool is provided for this purpose.
To establish an operational and functionally secure communication path, the following aspects must be taken into
account prior to and during planning:
•Natural and constructional influences limit the transmission ranges that can be realized. Building materials and
screening elements (e.g., installation shafts, fire doors, switching cabinet doors, etc.) must already be taken
into account during the planning phase.
High humidity increases the natural signal attenuation.
Warning
Recommendation: Plan the radio paths horizontally, on one level with max. 30 m distance
between transmitting and receiving components.
Note
•Observe the minimum distances to potential sources of interference
- min. 0.5 m to high-frequency interference sources (e.g., microwaves, transformers, computers...)
- min. 3 m to transmitters of other function systems (e.g., wireless telephones, headphones...)
- min 0.1 m to metal and door frames
•Minimize effective wall thicknesses, i.e. make wall passage of radio signals as vertical as possible.

•Do not choose the installation site in the radio shadow of screening building parts/volumes Îno direct
reception possible.
•In the fringe range of reliability, slightly change the position of transmitter/receiver if required
(to reduce heterodyne radio waves).

Multi radio connection MFA Device Description
Installation
Warning supply voltage 230 V for MFA multi-radio connection!
Danger Electrical installation of the device connection may only be performed by qualified expert
personnel (e.g. electricians)!
In this context, the regulations of the VDE (Association of German Electrotechnical Engineers) as well as the local
regulations are to be observed.
The devices shall be connected according to the terminal connection diagram or the applicable appliance
connection scheme.
Connection
MFA
Use only small servo drives with DC power supply.
Note
Addressing
In the housing, the MFA has 3 rotary switches for
setting the system code and the device address.
By means of the 3-digit address code, radio paths
can be established with theoretically up to 999
participants.
Terminals small
servo drives
Service key
multi-colored LED
2x address rotary switch

Terminals 230 V AC
Note The address code at the FCE must match the setting of the corresponding transmitting module (e.g.
TC12) so that an unambiguous allocation between transmitter and receiver of the radio path is
determined.

Multi radio connection MFA Device Description
Initial operation
LED displays
LED Function
off MFA receives no radio telegrams
green short blinking passive operating mode; module receives radio telegrams of other
transmission paths
green long blinking
(LED approx 1 s
on)
active service mode; module receives radio telegrams of the
assigned transmitters (FCS)
red permanent light error mode:
−Failure of the radio communication
Output signal 30 % (security position servo drive)
The error blinking of the LED continues as long as the
state causing the error remains
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.
