Siemens SIPROTEC 4 7SJ61 - Breaker Control

Breaker Control
Control Device
In devices with integrated or detached operator panel, switchgear can be controlled via the operator panel of
the device. In addition, control can be executed via the operator interface using a personal computer and via
the serial interface with a link to the substation control equipment.
Applications
•
Switchgears with single and double busbars
Prerequisites
The number of switchgear devices to be controlled is limited by the
binary inputs present
binary outputs present
Description
Operation Using the Keypad with Text Display
Using the navigation keys ▲, ▼, ◀, ▶, the control menu can be accessed and the switching device to be oper-
ated can be selected. After having entered a password, a new window is displayed in which multiple control
actions (e.g. close, open, cancel) are available and can be selected using the ▼ and ▲ keys. Thereafter, a query
appears for security reasons. After the security check has been completed, the ENTER key must be pressed
again to carry out the command. If this release does not occur within one minute, the process is aborted.
Cancellation via the ESC key is possible at any time before the control command is issued.

Operation using DIGSI
Switchgear devices can be controlled via the operator control interface with a PC using the DIGSI operating
program. The procedure to do so is described in the SIPROTEC 4 System Description (Control of Switchgear).
Operation Using the System Interface
Control of switching devices can be performed via the serial system interface and a connection to the switch-
gear control and protection system. It is therefore required to ensure that the required peripherals physically
exist in the device and in the power system. Furthermore, certain settings for the serial interface in the device
need to be carried out (see SIPROTEC 4 System Description).
