Auto synchronization mode
In this mode, the closing signal is delivered if either the command
Synchronize CB
or the input CL_COMMAND is set to TRUE. The relay should be in the local mode if
synchronization is initiated with the Synchronize CB command.
If the setting
Auto Syn mode
is set as "Manual mode" or "Semi-automatic
synchronising mode", the additional command Manual CB release should be active
for the closing signal CLOSE_CB to be activated. If the setting
Auto Syn mode
is set
as "Automatic synchronising mode", no additional command is required to activate
the closing signal CLOSE_CB.
In this auto synchronization mode, once all the closing conditions are satisfied
within the set
Maximum Syn time
, the outputs SYNC_OK and CLOSE_CB become
TRUE and remain active as long as the closing conditions are fulfilled. If
Multiple
command
is set to "Off", then only CLOSE_CB outputs are delivered once for each
activated input signal as shown in
Figure 858
. If
Multiple command
is set to "On",
then CLOSE_CB outputs are delivered each time the conditions are satisfied as
shown in
Figure 859
.
