2.3 Configuration of the Multi-Source System
The system must be configured correctly in order to ensure the uniformity of the different
time information from the sync. sources and to make the special multi-source settings.
2.3.1 Automatic / Manual Source Changeover
The source changeover takes place automatically as standard (factory setting). If not
required, this automatic changeover can be prevented, using Bit 3 of the ‘Control Bytes’
function. This may be necessary if, for example, it is known to the user that the time
information supplied by the secondary source is erroneous and cannot therefore be used.

The clock system status is always set to "
C
" (quartz) after every source
changeover -
automatic or manual
– so that it then synchronises to the
new source.
