are used to select the desired device in the Control
Display. The
I
key or the
O
key is then pressed to convey the intended control com-
mand.
Consequently, the switch icon in the control display flashes in setpoint direction. At the
lower display edge, the user is requested to confirm the switching operation via the
E
NTER
key. Thereafter a query for security reasons appears. After the security check is
completed, the
E
NTER
key must be pressed again to carry out the command. If this con-
firmation is not performed within one minute, the setpoint flashing changes again to
the corresponding actual status. Cancellation via the
E
SC
key is possible at any time
before the control command is issued.
During normal processing, the control display indicates the new actual status after the
control command was executed and the message
„command end“
at the lower
display edge. The indication
„FB reached“
is displayed briefly before the final indi-
cation in the case of switching commands with a feedback.
If the attempted command fails, because an interlocking condition is not met, then an
error message appears in the display. The message indicates why the control
command was not accepted (see also SIPROTEC 4 System Description). This
message must be acknowledged with
E
NTER
before any further control commands can
be 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 Inter-
face Control of switching devices can be performed via the serial system interface and a
connection to the switchgear control system. For this the required peripherals physi-
cally must exist both in the device and in the power system. Also, a few settings for
the serial interface in the device are required (see SIPROTEC 4 System Description).
