2. Function description
Self-setting movement with hour, minute and second display. For autonomous self-setting clocks for
indoor or outdoor use with dial diameters up to 80 cm, with or without illumination.
Connection compatible to SFA 130 / 140.
DCF-77 or MSF-60 radio control with automatic time take-over and daylight saving time
change-over by means of a connected radio time signal receiver.
Central-European time zones CET-1, CET and CET+1 selectable by DIP-switch.
Signalization of missing DCF/MSF time code reception after a period of one week by setting
the hands to 12 o'clock position.
Internal battery-less power reserve for at least 5 minutes operation (not for second hand).
Internal quartz clock for precise time display even without DCF/MSF radio reception.
Immediate resetting to the correct time after mains failure of up to 12 hours due to an internal
real-time-clock (battery-less powered).
Radio time signal output for the connection of a further movement. Up to 4 movements can be
connected to one radio receiver.
Different running modes of the second hand, selectable by means of a DIP-switch.
Possibility of connection of an MSF-60 radio receiver (Rugby) as well.
3. Mounting guidelines
3.1 Mounting of movement series BU 190(t) S
The dial must be sufficiently stable. The fixing hole must have a diame-
ter of 12.3 mm.
The movement must be fixed in vertical position.
Vide Fig. 3 for the position of mounting parts.
The disc nut (2*) M12 x 1 has to be tightened with a special wrench tool
(Art. No. 201998) and a torque wrench with a torque of 4.5 Nm +/- 0.2
Nm.
Attention:
The ring nut (5), the compensation ring (6) and the spring washer (7)
must not be removed.
After tightening of the disc nut (2*), the movement must not be
wrenched!
3.2 Mounting of hands and Starting-up
3.2.1 Mounting of hands
The shafts of the hour, minute and second hands are positioned ex-work on
the reference position (12 o’clock). The hands shall be carefully fixed and
tightened on the shafts. Enough space must be provided between the hands.
See Fig. 4.
The position 12 o’clock must be checked on each movement after the mount-
ing (Chap.3.2.2).

3.2.2 Starting-up and check of the hand position
Set DIP switch 1to ON position (12:00 Position, Fig. 5)
Connect the 48V power supply to the "AC/DC 48V" plug (Fig. 6).
The clock runs to 12 o’clock position.
Position of hands OK?
If the hand position is wrong, carefully loosen the hand, adjust and tighten.
Reset DIP Switch 1to OFF position
Check the 12 o’clock position again (initialising by an interruption of the power supply).
If hand position OK, continue with chapter 4 for further setting-up.

4.1 Synchronization with DCF or MSF time code
The Radio time signal receiver (DCF / MSF 450 (4500) must be connected to the terminals "DCF
in" and "48V GND" (see Fig. 6, 8, 9).
To ensure the reception quality, the designated pin of "AC / DC 48V" plug has to be connected with
earth potential (e.g. clock housing).
select time codes:
- For DCF set DIP-switch 4 to OFF position
- For MSF set DIP-switch 4 to ON position
Time: London local time (WET)
Select time zones:
Depending upon condition DCF can also be received in west Eu-
rope
(CET –1) (Greece, Portugal), or in east Europe (CET +1).
- for CET –1 set DIP-switch 6 to ON position
- for CET +1 set DIP-switch 5 to ON position

Control of the reception quality:
The orientation of the radio time signal receiver should be chosen in a way, the LED of the receiver
flashes regularly (at good reception quality the LED in the receiver flashes regularly in second
rhythm), see also the instruction manual of the receiver.
When reception condition is OK, the movement starts after about 3 minutes and set itself automati-
cally on the exact time.
