2. Installation guidelines
2.1 Installation of DMU 140 clock movements
The dial must be adequately rugged. The installation drill hole must have
a diameter of 20 mm.
The movements must be mounted vertically.
Fig. 2 shows the position of the components.
The washer nut (2) M20 x 1 is to be tightened carefully with a special
spanner accessory and torque wrench using a torque of 4.5 Nm +/- 0.2
Nm.
Caution:
Do not turn the movements any further after the washer nut (2) has been
tightened in place.
2.2 Installation of hands and commissioning
2.2.1 Hand installation
The hour and minute hand axles are positioned at 12:00 ex works. They
must be inserted on the axles and pressed down to the stop (X). They must
then be tightened in place without twisting the axles. See Fig. 3.
The 12:00 position must be checked in each movements after installing the
hands (chapter 2.2.2)
2.2.2 Commissioning and checking hand position
Set DIP switch 1 to ON (12:00 position, Fig. 5)
Connect MOBALine or DC power. The clock will turn to the 12:00 position.
Are the hands exactly at the 12:00 position?
If not then carefully loosen, adjust and retighten them (do
not twist the axle).
Recheck the 12:00 position (by briefly interrupting the
power supply)
If it's correct, continue with chapter 2.4 Mode Settings

2.4.1 Power supply voltage
This is via MOBALine or 10-30 V DC. To ensure DCF/MSF reception is as trouble-free as
possible, functional earthing is essential.

2.4.4 RS-485 terminating resistor
The termination resistor must be activated in clock movements at the end of a RS-485 line.
Open the clock movements cover cautiously to do so. The jumper is on the pc-board with DIP
switches. Replug the X8 jumpers X8 to activate the terminating resistor.

2.4.5 DIP switches
2.4.6 Synchronization
Set the DIP switches 3,4,5 as the synchronization mode dictates.
Set time zone and RS-485 address using the DIP switches 6 -11.
This setting is not needed in some synchronization modes.
DCF reception is shown by a regularly blinking of the DCF LED.
Correct synchronization is shown by the Synchronization LED.
After a brief period (see chapter 5) the clock will start running to current line time.
Example of calculating time zone and address setting:
Time zone Address
DIP switch 11 Off Value 1 0
DIP switch 10 On Value 2 2 Value 1 1
DIP switch 9 On Value 4 4 Value 2 2

2.4.7 Cascading wiring option
The DCF time code can be connected to the next movement via DCF-out. Synchronization in cas-
caded movements must be set to GPS (DCF UTC).

3. Function description
Self-setting movement for hour and minute hands. For self-setting clocks indoors and outdoors (under
glass covers) with a face diameter of up to 140 cm with or without lighting.
MOBALine, DCF77, MFS60 time code or controlled by MB-485-protocol via RS-485 with automatic
time take over.
Synchronization from a master clock or with DCF, MSF or GPS receiver.
DC power supply to a GPS receiver.
Operating mode, synchronization, time zone and RS-485 address selectable by DIP switch.
Self-setting, 12:00 position monitored by sensors with correction facility.
Two motors with forwards and backwards capabilities for rapid adjustment.
Power-saving mode with MOBALine - only one motor in use, with priority given to the minute motor.
Lack of MOBALine or RS-485 time signal during 24 hours is shown by resetting the hands to 12:00
o'clock position.
Lack of DCF77 or MSF 60 time signal during 7 days (7 x 24 h) is shown by resetting the hands to
12:00 o'clock position.
Immediate adjustment to the correct time after power interruptions of up to 10 h based on internal
quartz clock (battery-less time keeping).
DIP switch 2 is used to select the minute hand function mode, continuous or in minute steps.
MOBALine ignores this switch. The running mode is selected via the line mode of the master clock,
with half-minute steps becoming minute steps.
Output of a synthetic DCF77 code, when movement is synchronized with DCF77 or MSF 60 (UTC).
Status LED for power supply, DCF impulses and synchronization.
