5.5
Use of the automatic synchronizing device as synchrocheck
If the device is to function as a synchrocheck, the following parameter settings have to
be adjusted in the corresponding parameter set:
1. Switch off command generation: tp on = OFF or 0
2. Switch off voltage matcher: dU/dt = 0,00 %/s
3. Switch off frequency matcher: df/dt = 0,00 %/s
If the device is used alternatively for automatic synchronization and as a synchrocheck,
the configuration described in section 5.4.1 can be used.
5.6 Communication
5.6.1 Service
interface
The service interface is intended to be used for commissioning and maintenance. During
operation, it may be permanently connected to an engineering workstation.
In connection with the service interface, it is intended to use SynView (see section
2.9.1). The optional password of SynView can be used to prevent writing data to the
SYNCHROTACT during operation.
5.6.2 Operating
interface
(option)
The operating interface is intended to be used for operational control. Changing the
parameter setting of SYNCHROTACT 5 is not possible via this interface. Refer to
section 2.9.2 for more information about transmitted signals.
Data has to be written to or read from certain addresses in SYNCHROTACT 5 (see
section 4.3). The project engineer (e.g. of the control system) is responsible for the
visualization on the screen.
If both, the conventional control (hardwired) and the operating interface are used
alternatively (e.g., local control and remote control), the blocking input (connector -X1b)
can be used to block the operating interface. The conventional control can be blocked
externally by interrupting the control voltage.
The figure below shows the application of the blocking input "BLK REM" as an example.
An active signal on "BLK REM" will block control via operating interface. Exceptions:
The STOP input is permanently active, i.e., blocking is disabled
The functional code of the configurable inputs can be set as negative value (minus
as sign). This disables blocking (refer to input IN3 of the above figure).
