Parameter Set - ABB SYN 5201 Operating Instructions Manual

Operating Instructions
7.3 Operational control
When commissioned and ready for operation, the device is controlled via the digital
control inputs on the device.
7.3.1 Starting and stopping the synchronizing process
The Start command initiates the synchronizing process.
In the case of devices with several parameter sets or configured control inputs, the
corresponding pre-selections must be made before starting the synchronizing process.
No control actions are necessary during operation. Changes to the parameter settings
are not possible during normal operation.
After the circuit breaker has closed, its auxiliary contact (normally open) gives the
automatic Stop command. The synchronizing process can be terminated prematurely
using the Stop command.
7.3.2 Test mode (option)
If the necessary hardware (SYN 5014) is installed and appropriately configured, the
TEST mode can be used. If this is selected, the device goes into BLOCKED status. The
paralleling relay is blocked. The relay configured for this purpose will close in its place.
7.3.3 Switch-over hardwired control <-> operating interface
If selector switch is used to select hardwired control (e.g. local control) or operating
interface (e.g. remote control), it can also be used to activate one and block the other
control possibility. The selection can be done in any status of the synchronizing
equipment.
7.3.4 Operating interface
Control commands and state messages can be routed over the operating interface
instead of through the conventional wiring. It is not permitted to close the circuit breaker
from the operating interface. It is not recommended to send voltage matching
commands or frequency matching commands without consulting the manufacturer.
With the redundant dual channel device SYN 5302, the control commands must be
written in parallel to both operating interfaces. The interfaces themselves are not
redundant.
