VI - PRINCIPLE OF TIME SETTING

6.1 AFNOR receiver model

1. On the initial powering up, the time is initialised at 00h00mn00ss on 01/01/2000.
After a powering up, a time setting, a reset or a new configuration, the clock search to be
synchronised. Since 3 consecutives correct messages have been received, it set up its time
base to the correct time. After, it is automatically done each hour.
Between 2 synchronisation, the time base bring forward according to the internal base.
If the clock is in mode COD
If the clock is in mode LOC
mode menu (Seasonal change and offset change).
Caution: if the current time of the master clock is modified after the synchronisation of the
slave clocks, the correction will be achieved the next hour.
2. If the synchronisation is not correct after 20 seconds, a new time code search is made the
following minute.
If the synchronisation is not correct after 24 hours, the clock pictogram will flash every 5
seconds, the display disappeared with only the 2 dots fixed.
If the AFNOR synchronisation is not correct after 1 hour, the clock pictogram flashes every
second and the clock keeps on working on its own time basis.
In AFNOR mode, if the synchronisation is not correct after 24 hours, the clock pictogram
flashes every 5 seconds and the display disappears with only the 2 dots fixed.
In AFNORI mode, if the synchronisation is not correct after 24 hours, the clock keeps on
working on its own time basis with the 2 dots fixed.
Nota : On an Irig-B network, year must be manually entered by the user.

6.2 DHF clock

On leaving the factory, the DHF clock is set in "Initialisation" mode. After inserting the batteries,
the clock displays INIT for 5 seconds then 00:00.
The synchronisation search is limited to 4 hours. Beyond, the clock stops searching and
displays only 2 fixed dots. A press on one of the keys will restart the synchronisation search
for 4 hours.
It memorises the address of the transmitter and switches to normal mode automatically when
time is received.
In case of interference or absence of signal:
In DHF mode, if the synchronisation is not correct after 24 hours, the clock pictogram flashes
every 5 seconds and the display disappears with only the 2 dots fixed.
In DHFI mode, if the synchronisation is not correct after 24 hours, the clock keeps on
working on its own time basis with the 2 dots fixed.
If needed (change of communication channel, new installation...), the clock can be switched
to "Initialisation" mode in the technician menu.
