2. Function description
Self-setting movement with hour and minute display. For autonomous self-setting clocks for indoor or
outdoor use with dial diameters up to 80 cm, with or without illumination.
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).
Serial time signal output for the connection of a further movement. Up to 3 further movements
can be connected in this way.
Possibility of connection of an MSF-60 radio receiver (Rugby) as well.
Serial input (RS 232 / 422) for time setting and synchronization with standard ASCII time tele-
gram (definition IF482).
3. Mounting guidelines
3.1 Mounting of movement series 190(t)
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).

To ensure the reception
quality, the designated pin
of the DCF plug has to be
connected with the earth
potential (functional earth,
i.e. clock housing).
3.2.2 Starting-up and check of the hand position
Set DIP switch 1to ON position (12:00 Position, Fig. 5)
Install the AC 230V power supply by using the white two wire cable from the movement.
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.

If the 12 o’clock position of the clock is OK, reset DIP Switch 1to OFF position (Fig. 5).
The movement can be synchronized with following time codes:
- DCF, MSF (see chapter 4.1)
- Serial time telegram (standard IF 482 telegram) by RS 232 or RS 422 with local time
(see chapter 4.2)

4.1 Synchronization with DCF or MSF time code
The DCF 77 - Radio time signal receiver (DCF / MSF 450 (4500) must be connected with plug DCF
on the movement (see fig 6).
To ensure the reception quality, the designated pin of DCF plug has to be connected with earth po-
tential (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 Europe
(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

Connection to
the mains
supply should
be realized
according to
the class II
protection.
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.
The movement starts after about 5 minutes and set itself automatically on the exact time.
4.2 Synchronization with serial time telegram (IF 482)
The movement can be synchronized with RS 432 or RS 485 over standard-RS 485 telegram. Time
will be interpreted and shown as local time. See chapter 5.1 for telegram definition.

6 RS-422 IN (RD -) View from contact side
4.3 Connection / cascading
To connect the radio signal to a double sided clock (two movements), there are two possibilities:
Possibility 1: The radio signal can be distributed on both movements with a DCF multipler
(Art.No. 35 821) (Fig. 11).
Possibility 2: The time signal is sent to the second movement over a "COM 192" cable (Art. No.
200045). Therefore the signal is connected from the OUT-plug of the master-movement
to the IN-plug of the slave movement (Fig.10). Disadvantage: If master-movement fails,
slave-movement will also stop.
