20 S&C Instruction Sheet 766-540
Operation Using IntelliLink® Setup Software
Ground Trip
When blocked, this function prevents the IntelliRupter fault interrupter from tripping
because of a
Ground Overcurrent
element. It is commonly used when work is performed
on one phase, that would be seen as a larger-than-normal load imbalance. This function
does not activate a
Ground Overcurrent
element if one has not been set up in the active
profile.
Test on Backfeed
When enabled, this function allows the use of PulseClosing Technology or close
testing after an initial trip when there is voltage on both sides of the IntelliRupter fault
interrupter. Testing is usually blocked in applications involving distributed generation
to prevent closing on the other generator if it has not yet tripped offline. When the
Test
on Backfeed
feature is blocked, the IntelliRupter fault interrupter does not immediately
go to the
Lockout
state after tripping but instead waits for the voltage to go away on one
side before resuming the specified time periods in the test sequence. If voltage on both
sides stays on for an interval of 5 minutes, the IntelliRupter fault interrupter goes to the
Lockout
state. When configured to block testing, the
Test on Backfeed
function is only
enforced when all three poles are open; it is not enforced when in a
Pole Mismatch
state.
Hot Line Tag
The
Hot Line Tag
mode can be applied by clicking on the
On
button; the “IntelliLink”
indication will be displayed. When the
Hot Line Tag
mode is applied by SCADA, the
“SCADA” indication will be displayed. When the
Hot Line Tag
mode is applied using the
HOT LINE TAG lever, the “Lever” indication will be displayed. When the
External Trip
option is present and the
Hot Line Tag
mode is applied by the External Trip interface,
“External” will be displayed. The “External”
indication will not be displayed on the
Operation
screen unless the option is present. The
Hot Line Tag
mode is normally
removed using the same method by which it was applied. However, a second operation
of the HOT LINE TAG lever will clear an electronically set
Hot Line Tag
mode.
Ground Trip Block Lever
This field indicates the position of the GROUND TRIP BLOCK lever.
Ground Trip Block External
When the
External Trip
option is present, this field indicates the External Interface
Ground Trip Block
input is active when “On” is displayed.
Maintenance Mode External
When the
External Trip
option is present, this field indicates the External Interface
Maintenance Mode
input is active when “On” is displayed.
External Port Linked
(R2 control only)
When the
External Trip
option is present, this field indicates the
External Port
data
flow is active when “On” is displayed.
Circuit Testing
When enabled, this function allows for the use of PulseClosing Technology or close testing
after the initial trip. When blocked, the IntelliRupter fault interrupter goes immediately
to the
Lockout
state after tripping.
Sensitive Earth Trip
When enabled, this function allows the IntelliRupter fault interrupter to trip for a
Sensitive Earth Overcurrent
element. This function does not activate a
Sensitive
Earth Overcurrent
element if one has not been setup in the active profile.
Clear Latched Overcurrent Button
Clears the Latch Overcurrent indications if set when this button is activated.
