Application And Setting Notes (External Synchronization) - Siemens 6MD85 Manual

Notes for Optional Input Interconnections
You have the option of connecting the input signals
omit these interconnections, observe the following instructions:
Input >Close cmd. released :
If you do not interconnect the input signal
command with synchronization requirement is confirmed directly (execution successful: OPR+), as soon as the
output signal Start syn. process is set. In this case, the (_:109) Max.durat. sync.process
setting has no meaning. If you use a control model with feedback monitoring, consider that the feedback
monitoring will start immediately when the
Feedback monitoring time setting must therefore be set higher than the maximum synchronization
time of the external synchronization device plus the circuit-breaker closing time. If

sync.process) has expired.
Input >Op. mode 'dir.cls.cmd' :
In case of a failure of the external synchronization device, you can also close the circuit breaker directly
without considering the synchronization conditions. To do this, activate the input signal
'dir.cls.cmd' or the parameter (_:110) Direct close command. The close command is then issued
directly by the bay controller.

Application and Setting Notes (External Synchronization)

6.4.14.2
Parameter: Mode
•
Default setting (_:1) Mode = on
With the Mode parameter, you switch the external synchronization function on or off. If you set the Mode
parameter to off, a circuit-breaker close command with synchronization requirement is rejected.
Parameter: Max.durat. sync.process
•
Default setting (_:109) Max.durat. sync.process = 30 s
The Max.durat. sync.process parameter defines the maximum synchronization time. The time starts
when the External synchronization function block sends a close command to the external synchronization
device. The command must be executed within this time. If the close command is not executed within this
time, the External synchronization function block sends a command to cancel closing to the external
synchronization device.
Parameter: Direct close command
•
Default setting (_:110) Direct close command = no
In case of a failure of the external synchronization device the Direct close command parameter is used to
close the circuit breaker directly without considering the synchronization conditions. If the parameter is acti-
vated a close command with synchronization requirement will not be transmitted to the external synchroniza-
tion device, but directly carried out by the bay controller.
