4. Mounting and Starting-up
4.1 Starting-up of a completely assembled clock with FU 192
Install the power supply as per Chapter 4.2.3.
At the foreseen clock place align the antenna and check the reception, see chapter 5.1 page 7.
4.2 Mounting of hands and Starting-up
4.2.1 Mounting of hands
The shafts of the hour and minute 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
foreseen between the hands.
The position 12 o’clock must be checked on each movement after the mounting (chapter
4.2.2).
4.2.2 Starting-up and check of the hand position
Pull out the IN plug (the 12 o’clock position must be separately checked in case of cascade
connected movements).
Install the power supply as per chapter 4.2.3 The clock runs to 12 o’clock position
Position of hands OK?
If the hand position is wrong, carefully loosen the hands, adjust and tighten.
Check the 12 o’clock position again (initialising by a short interruption of the power supply).
Insert the IN plug (data connection)
Check the reception, see chapter 5 page 7.
Attention:
After a correct adjustment the hands must not be turned manually any more!
If the clock in the meantime has been once synchronized, the movement will behave as per
4.3.1.
4.2.3 Mounting of Power Supply
To open the battery box lift the cover with a screwdriver,
which is placed in the foreseen space, and press lightly
downwards (Fig. 3). Possible power supplies for this series of
movements:
Var.1: 1 Lithium battery 3.6V 27Ah 250394
Var.2: External power supply 230 VAC 201670
Var.3: 2 Monocells LR20 1.5V 33mm x 60mm
Fig. 3
Attention:
Please pay attention to the polarity of the power supply!
As soon as the movement is under power, the hands will start
moving.
Advice:
The electric contact can be improved through a slight
tightening of the synthetic screw.
The lithium battery and the mains part shall be connected by
using the corresponding connection wires.

4.3 Function of the operating key (Fig. 5)
4.3.1 FU / BU 192 (t) in normal operation
The clock has been synchronized once at least !
Key touch < 5s Switch on radio signal reception
Key touch > 5s Positioning onto reference position 12 o’clock
When the hands have been set on 12 o’clock with a key touch > 5s,
they remain in this position during 10 minutes and will then start running
autonomously to the correct time.
With a brief key touch the hands will run to correct time immediately.
If the clock has to be disassembled or the hands adjusted anew, it is
recommended to remove the power supply, after that the hands have
stopped at 12 o’clock.
This will prevent, that the hands suddenly will start running after 10
minutes.
If the movement never has been synchronized, it will behave as per
chapter 5.4, page 8.

4.4 Remote control by means of external key (Fig. 6)
The functions with external key are identical
with those of the internal operation key
(chapter 4.3.1 und 5.4 page 6).
The external key will be connected on the
plug position OUT. For the connection of the
plug see chapter 11, page 18.
An external key including 5 m cable is
available (KEY 192).

5. Synchronization
5.1 Synchronization by Antenna AD 192 (DCF-77kHz)
Check radio signal reception Orientation of the antenna:
The antenna should be oriented towards the site of the emitter
(Mainflingen near Frankfurt a.M. / Germany).
Check the reception quality by the side-positioned LED
(Fig. 5, page 6).
The LED should flash regularly in second pulses.
Activate reception by a brief key touch (Fig. 5, page 6).
At bad reception push the antenna backwards from the fixing
device and turn it round its own axle (Fig. 7). This will change
the orientation of about 40°.
Should the reception quality, in spite of the turning round the
own axle, not has improved much, the antenna can be optimally
placed and oriented by means of an extension cable CAB 192.
A weatherproof (IP54) antenna (AD 192.5) for outdoor use is
available for especially difficult cases.
OUT IN
Fig. 7
The radio signal reception is on as long as two valid telegrams are picked up. At good reception
conditions the movement should move to actual time after about 2 - 3 minutes.
For further information concerning the radio signal reception, see chapter 9.2 page 16.
The movement can also be set manually to correct time (chapter 5.4 page 8).
5.2 Synchronization by Antenna AM 192 (West European Time)
The movement can also be controlled by an antenna from MSF-Rugby 60kHz.
The emitting station is in Rugby, England. The same rules of reception as for DCF-antenna are
valid (chapter 5.1).
Important:
Before installation the movement must be coded for MSF operation.
A solder bridge underneath the OUT plug (Fig. 8, page 8) must be added.
In the MSF operation mode the solder bridges M+1 and M-1 have no influence.
5.3 Synchronization with AD 192 (DCF) in the time zones MEZ+1 or MEZ-1
The movement with the DCF-77 antenna (FU 192) can also be used in the time zones WEZ (West
European Zone) or EEZ (East European Zone), if the radio signals can be received in these zones
and if the daylight saving time (DST) change-over is the same as for MEZ.
Before starting-up the movement should be coded for the corresponding operation mode by means
of a soldering bridge (M+1: MEZ+1, M-1: MEZ-1) (Fig. 8 page 8).
Important:
Only one soldering bridge must be added, otherwise the correct function cannot be guaranteed.

5.4 Synchronization by means of internal or external key
Valid for FU-, BU- and QU 192, as well as for movements in cascade connection:
Operation device: Internal key (Fig. 5, page 6), or external key (Fig. 6, page 6)
Condition: Movement(s) have not yet been synchronized through a external source.
This condition is also performed after an interruption of the power supply.
If the movement was synchronized before (FU-, BU 192) and the power supply
not interrupted, the reaction will be as per 4.3.1.
Key touch < 2s Forward motion of 1 minute or stop of forward motion
Key touch > 2s Forward motion of 1 hour LED is blinking slowly
Key touch > 5s Forward motion of 11 hours LED is blinking quickly
Each key touch sets the time on the beginning of a minute. So the time can be set within an
accuracy of ±1sec.
In case of movements in cascade connection all movements react at the same time with the key
touch of one of the movements. The external key can thus be plugged in the last movement.
5.5 Synchronization of the BU 192 by means of serial telegrams over IF 494
Instead of using an antenna, time can be read-in from a serial telegram. By means of an interface
IF 494 a serial telegram can be transmitted to the movements BU 192 or QU 192. The interface
connection (IN plug) is identical with the antenna connection (Fig. 7).
IF 494, connection possibilities, see page 18.
The synchronization time is about 3 sec. with telegrams sent every second. See chapter 8.3, page
13. Definition of the serial telegrams, see chapter 7, page 11.
5.5.1 Synchronization by local time
The movements BU 192 and QU 192 can be
synchronized by local time (Chapter 7.1,
page 11).
The external device must always transmit the
local time in serial telegrams, as the
movements BU / QU do not automatically
switch onto daylight saving time.
That means, that in this operation mode the
movements will always show the time
transmitted in the telegram.

5.5.2 Synchronization by UTC time
The movement QU 192 can also be synchronized by UTC time (chapter 7.2, page 11).
In this operation mode the movement will autonomously calculate the local time as per predefined
season data for MEZ (Middle European Zone). Should the QU 192 be used in another time zone,
the offset to UTC-time and season data must be programmed by means of a special serial
telegram (chapter 7.4, page 12).

© MOBATIME 9 / 20 800163.10
5.6 Concept for sending and receiving serial telegrams
After the starting-up the BU 192 waits in "Run" mode until the serial telegram arrives. When the
movement has received two telegrams with the correct time, it runs to the actual time. At each
minute change a telegram will be sent and received. In the second 3 the movement switches again
to current saving mode.
The memorized time information deviates in the seconds range or falls out:
If suddenly no telegram occurs between seconds 0 and 3, the movement remains in "Run" mode.
After 4 minutes the information from the time source will be deleted, the movement switches onto
current saving mode and continues to run un-synchronized on its own time base (quartz precision
BU192 50ppm).
When the serial telegram re-appears, the movement will be "waked up", takes over the time from
the telegram and runs normally again. Should no telegram occur any more, the movement will
activate the radio reception once every hour. If in the meantime an antenna was connected, the
time will be taken over from DCF.
After 7 days without time reception, the clock runs to 12 o’clock and stops running.
Duration of the time take-over:
The telegram will be transmitted every second:max. 3 sec.
The telegram will be transmitted every minute (e.g. save movement in cascade): max. 3 min.

6. Cascade
Cascading means that a number of movements will be
connected in series.
Up to three slave movements BU192 can be connected to
one master movement (Fig. 9).
As master movement the following types can be used:
FU 192
QU 192
BU 192 with serial synchronization (over IF494)
The cascading is done by means of a cascade cable COM
192 (length 1m), enabling to synchronize 4 movements with
only one reference signal. After the starting-up the time
synchronization for all movements will follow in a few seconds
only. Should the time for the master movement change during
the normal operation, the time take-over for each connected
movement will take about 2 minutes, which means totally
about 8 minutes. This is also valid for the daylight saving time
change.

6.1 Starting-up of cascaded movements
As master movement should be used a FU 192 with radio signal reception, a BU 192 or a QU 192
with serial synchronization:
Connecting of the power supply movements run to the reference position (12 o’clock).
Wait until the master movement has taken over the time.
The master movement has taken over the time:
Starts to run on correct time.
Starts to transmit serial telegrams over the OUT plug (chapter 7.3 page 11)
Some seconds later the slave movements start running to the time of the master movement.
As master movement should be used QU 192 with manual time setting:
Separate the first slave movement (IN plug) from the OUT plug of the QU 192.
Connect the power supply movements run to the reference position (12 o’clock).
Set the QU 192 to correct time by means of the internal or external key (chapter 5.4 page 8)
Connect first slave movement with QU 192 OUT plug.
After 3 minutes at the latest the slave movements start running to the time of the master
movement.
Remark:
In the cascaded movements all the internal keys are connected in parallel.
On the OUT plug of the last movement an additional external key can be connected.
Each key touch influences all the movements.
6.2 Master movement Time setting with serial telegrams
A BU 192 or a QU 192 requires at least 2 serial telegrams with valid time. That means, when the
same telegram will be transmitted several times, the movement will never take over the time. As
the time always continues to run, also he seconds and minutes must be incremented in the
telegram.
The date must be a valid value. It can, however, remain constant. (e.g. 01.01.01).
Attention:
After the time setting the QU 192 accepts no new time for about 3 minutes !
