Control Device

2.10.2
Switchgear can be controlled via the device operator panel, PC interface and the serial interface as well as a
connection to the control system for switchgear with single and double busbars.
The number of switchgear devices to be controlled is limited by the number of binary inputs and outputs.
2.10.2.1

Functional Description

Operation via integrated control panel
Using the navigation keys ▲, ▼, ◀, ▶the control menu can be accessed and the switchgear to be operated
selected. After entering a password, a new window is displayed where multiple control options (ON, OFF,
ABORT) are available using the ▼ and ▲ Then a safety query appears. Only after repeated confirmation using
the ENTER key is the command action performed. If this enabling 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
or during breaker selection.
If the attempted command fails, because an interlocking condition is not met, an error message appears in the
display. The message indicates why the control command was not accepted (see also SIPROTEC 4 System
Description). This annunciation must be acknowledged with ENTER before further operation of the unit is
possible.
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. Please check MLFB order number to ensure that your individual relay has a
SCADA interface module that supports this. Furthermore, certain settings for the serial interface in the device
need to be carried out (see SIPROTEC 4 System Description).
