11.1 Time synchronisation menu
To congure the time synchronisation of the SIGMA, validate the option in the
technician menu with the key,
The following screen is displayed :
Select the time synchronisation mode from
the following options:
Radio FI/DCF,
Minute radio (mode used for countries
receiving the FI/DCF radio signal but for which the time is different from Paris/
Berlin [only minute is synchronised, date and hour must be set manually]),
EXTERNAL (mode used for synchronisation from a Sigma “Master”
which transmits a GPS signal simulation from an ASCII extension card),
NONE: if you choose to have no synchronisation, the radio pictogram is
not displayed.
GPS,
AFNOR (requires an option board),
Auto (the master clock will select the best time source automatically; in
that case, several time sources can be connected to the master clock;
it will change time source in case of failure of one of them; the priority is
given at rst to AFNOR then GPS, FI / DCF).
Remark : all the synchronisation options are proposed without checking
that an antenna is connected (by default, the conguration is FI/DCF
mode).
In case of synchronisation input failure, an alarm message is sent.
This alarm is triggered after 3 hours without synchronisation in Auto
mode, after 24 hours in the other synchronisation modes.
Select the synchronisation mode with the and keys and validate with
the key.
The following screen is displayed if “Prog”
mode has been validated in the customer
menu (see “Time and date”, page 22) :
This menu can be used to program non-
standard winter/summer time changeovers.
