TIE: The red LED indicates the control is in tie mode and
will respond to voltage conditions on Source I and/or
Source II.
SECTIONALIZER: The red LED indicates the control is in
sectionalizing mode and will respond to voltage conditions
on Source I.
Note: When in Sectionalizing mode, the SOURCE II ENABLED
function key is not responding to voltage even though it
is illuminated.
LS DISABLED: The red LED indicates the LS accessory is
not active. When LS is disabled, the Form 6-LS control will
not respond to the LS loss of voltage parameters as set in
the ProView interface software Loop Scheme Settings
Dialog screen located in the Idea Workbench.
Note: In the event of loss of AC control power to the control
(without battery back-up power), the LS control will be
disabled when power is restored to the control:
• In the TIE Mode, once voltage is restored, the LS is
disabled until locally or remotely enabled. This is to
ensure that the TIE recloser will not close automati-
cally upon restoration of voltage from one source.
• In the SECTIONALIZING mode, once voltage is
restored, the LS is disabled until locally or remotely
enabled. The recloser remains in the same state prior
to the loss of voltage. The SECTIONALIZING unit will
not close automatically. This also prevents any auto-
matic closing when auto reset is enabled.
Note: LS must be enabled via the ProView interface software
Loop Scheme Settings Dialog screen located in the Idea
Workbench.
A PHASE VOLTAGE, B PHASE VOLTAGE, C PHASE
VOLTAGE: These red memory LEDs indicate the appropri-
ate phase(s) that initiated the Loop Scheme functionality.
These LEDs are controlled by the Voltage Controls settings
in the Loop Scheme Settings dialog box.
If LS is enabled, at the moment loss of voltage occurs, the
LEDs for the phases that lost voltage turn off and the LS
option begins timing.
Note: The TIE mode will not initiate any loss of voltage timing if
both sources are lost. If one source is available, while the
TIE mode is timing on loss of voltage, and the available
source also loses voltage, the TIE will reset the loss of
voltage time to its original value.
If voltage is restored before the voltage transfer time delay
elapses, the LEDs for the phases with restored voltage
illuminate and the LS timer resets.
If voltage is not restored before the Voltage Transfer time
delay relay elapses, the LEDs remain off even if voltage
returns to a particular phase. This identifies the phase that
caused the LS to operate.
Activating the LS RESET one-touch function key resets
the LS function and illuminates these LEDs (if voltage is
present).
FREQUENCY TRIP: Indicates the recloser tripped due to
an under or over frequency condition.
VOLTAGE TRIP: Indicates the recloser tripped due to an
under or over voltage condition.
X PHASE VOLTAGE, Y PHASE VOLTAGE, Z PHASE
VOLTAGE: These red memory LEDs indicate Source II (load)
voltage is present on X, Y, or Z phase(s). These LEDs are
controlled by the Voltage Controls settings in the Loop
Scheme Settings dialog box.
If LS is enabled, at the moment loss of voltage occurs, the
LEDs for the phases that have lost voltage turn off and the
LS option begins timing.
Note: The TIE mode will not initiate any loss of voltage timing if
both sources are lost. If one source is available, while the
TIE mode is timing on loss of voltage, and the available
source also loses voltage, the TIE will reset the loss of
voltage time to its original value.
If voltage is restored before the voltage transfer time delay
elapses, the LEDs for the phases with restored voltage
illuminate and the LS timer resets.
If voltage is not restored before the Voltage Transfer time
delay relay elapses, the LEDs remain off even if voltage
returns to a particular phase. This identifies the phase that
caused the LS to operate.
Activating the LS RESET one-touch function key resets the
LS function and illuminates these LEDs (if voltage is
present).
INDICATOR 7, INDICATOR 8: Customizable LEDs that are
used with functions programmed through the Idea
Workbench. The LED indicators do not have active default
values. The LEDs are illuminated when the status config-
ured via the Idea Workbench is present.
Operating Panel
RS-232 Configuration Data Port
The RS-232 connector (shown in Figure 4) on the front
operating panel allows direct connection to a personal
computer without any special cables or connectors. This
port is used only for configuring the control with ProView
application software. All settings, metering, events, and
oscillography data are available from this port. The port is
Data Communication Equipment (DCE) wired for direct
connection to a personal computer.
A 9-pin RS-232 cable (Catalog Number KME5-66) to
connect from the PC to the RS-232 data port is available
as an accessory.
