Non-network clock operation
Choose the item
P4
in main MENU (chapter 5) and set the type of synchronization. The auto
detection mode (P4:A), when the type of synchronization signal is set automatically, is
applicable for DCF signal, Mobatime serial code, MOBALine, Active DCF. The permanently lit
colon during the time display signalizes the clock is synchronized by the synchronization
source.
10.1
Autonomous clock synchronized by DCF 77 receiver
•
Set value
A
in items
P3
,
P4
and
P7
in the main MENU (chapter 5).
•
Connect the DCF 77 receiver to the clock terminal board placed on the anchoring
plate (LINE IN terminals) using a twin-wire cable.
•
The maximum wire length depends on its diameter (app.100 - 300 m).
•
In case the connection is correct and the input signal is at high level, the LED on
the receiver is flashing periodically once a second, with 1 pulse left out at the 59th
second.
•
If the polarity is incorrect, the LED does not flash. In such a case, interchange the
two wires.
•
Install the receiver at a place with a high-
level radio signal. Don’t install the
receiver near sources of interfering signals, such as the personal computers, TV
sets or other types of power consumers (the digital clock itself generates
interfering signals too).
•
Face the radio receiver with the front cover (with screws) towards the Mainflingen
DCF transmitter (approximately to the west). If the DCF reception is good, the time
base on the connected clock will be synchronized automatically within a few
minutes. In case of poor reception (especially during the day), the first setting must
be made manually so that the LED flashes regularly.
10.2
Slave clock controlled by synchronizing impulses
On digital clock connected in time distribution system controlled by synchronizing
impulses choose the item
P4
in the main menu and set it according type impulse lines
(one minute, half minute, second pulses) and in item
P5
choose mode of processing
impulse line (polarized / unpolarized impulses, synchronization and time setting /
synchronization only). Set the value
A
in items
P3
and
P7
.
10.2.1 Synchronization and time setting
– P5 mode 1 and 3
Clocks are set according to the slave line time on the Master clock.
•
Stop the slave line on Master clock.
•
Set all slave clocks on the same time. Set the current date on the digital
clock. The clocks stand still and the colon flashes in 2 second interval.
•
Set the time of the slave line to the same time as on slave clocks.
•
Run the slave line on Master clock.
•
After receiving each impulse is displayed time increased by one minute (or
by 30 seconds or 1 second respectively)
•
After the expiration of run-out time the slave clocks are synchronized by the
time information generated by the master clock, the colon flashes
constantly.
