MOBALine
Movement
SEM 40 V2 / SAM 40 V2
Self-setting movement with hour, minute and second display.
Suitable for indoor and outdoor clocks with dial diameters up
to 400 mm.
Types:
SEM 40 V2 (with second) Art. Nr.: 129426
SAM 40 V2 (without second) Art. Nr.: 129425
-Fully controlled by a connected MOBALine master clock.
Automatic time adjustment and daylight saving time
changes. Signalization of missing MOBALine code recep-
tion after 24 hours by setting the hands to 12:00 position.
-The movement supports synchronization with DCF active
signals of modes 1, 3, 4 and 6 (see below). Summer and
winter time changeover takes place automatically. A failure
of the time signal is indicated after 7 days by setting the
hands to 12:00 o'clock.
-The DCF-impulse code is also supported.
Same function as DCF active.
-Two motors: minute / hour and second.
-Different running modes (stepwise or continuous) of the
minute and second hand selectable by means of DIP-
switches. When using MOBALine, the running mode can
also be set on the master clock.
-World time function supported by selection of a MOBALine
world time zone (1 out of 20 selectable by DIP switches).
This function is not available with DCF active signal.
-Fully powered by the connected time signal.
DCF active supported modes:
Unipolar:
Bipolar:

2 Configuration
The movements SEM 40 / SAM 40 V2 have 12 DIP switches on the housing back side. The following
configuration settings are possible:
Switch: Position OFF: Position ON:
1 ON
123456789101112 Movement runs on time (if syn-
chronized and no other
MOBALine command is active)
Movement runs to 12:00 position
2 ON
123456789101112 Second hand in stepwise mode Second hand in continuous
mode
3 ON
123456789101112 Minute hand in stepwise mode Minute hand in continuous mode
4 - 8 ON
123456789101112 Clock runs on the line time giv-
en out by the master clock:
4: 0
5: 0
6: 0
7: 0
8: 0
Selection of world time zone (bi-
nary value):
4: 1
5: 2
6: 4
7: 8
8: 16
9 ON
123456789101112 Standard Swiss Railway Mode (SBB).
Overwrites the settings done with
DIP switches 2 and 3.

Second and minute hand
modes are defined by DIP
switches (2/3/9)
Second and minute hand modes
are defined by MOBALine (with
DCF active, this switch is not
used)
11 - 12 - No function No function
Recommendation: Set configuration switches prior to applying power (MOBALine signal).

3 Installation
1. Set the DIP switch 1 to ON or set the slave clock line of the
MOBALine master clock to the STOP state
2. Connect the clock to the time signal (MOBALine or DCF active).
(The input is located at the 6 o’clock position)
3. Wait until the movement stops
4. Insert metal pins carefully without force into the two holes on the back
side (ill. 1). It should be possible to insert the pins about 6-7mm deep.
Maybe move the hands slightly.
5. Mount the parts to the shafts in the following order:
- rubber washer
- dial
- metal ring
- ring nut (torque 4.5 Nm +/- 0.2)
- hour hand
- minute hand
- second hand
During the assembly, the movement must rest on
a stable surface (ill. 2).
Otherwise the movement can be damaged!
6. Adjust the hands to 12 o’clock
7. Remove the pins
8. Set the DIP switch 1 to OFF or set the slave clock line of the MOBALine master clock to
the RUN state
4 Maintenance
If maintenance is necessary, repeat the steps 1-8 in chapter 2.
5 World time function
The movements SEM 40 / SAM 40 support the MOBALine world time function. On the master clock
(e.g. DTS, ETC, CTC or MTC) you can configure up to 20 different world time zones with different lo-
cal time offsets (e.g. New York, London, Brussels, Tokyo, etc.) which will be transmitted to the slave
clocks by means of MOBALine world time telegrams.
With the switches 4 to 8 one out of the 20 world time zones can be selected. Further details regarding
the configuration of the world time function can be found in the manuals of the corresponding master
clocks.
With the selection of an invalid time zone or one, which is not defined on the master clock, the normal
MOBALine line time will be displayed. The same happens with the standard settings (DIP switches 4
to 8 set to OFF position).
