manually apply the Ground Trip Block mode.
Manually Applying a Hot Line Tag
Follow these steps to manually apply a hot line tag:
STEP 1.
Insert the hookstick into the ring on the HOT LINE TAG lever. See Figure 7.
STEP 2.
Pull down on the lever. If desired, tag or lock it in this position. See Figure 8 on
page 11.
STEP 3.
Observe the amber HOT LINE TAG indicator on the protection and control
module. See Figure 9 on page 13. When the
Hot Line Tag
mode is applied, the
indicator will flash amber for a ½ second every 2 seconds.
The
Hot Line Tag
mode can be set locally using the HOT LINE TAG lever or remotely
using a SCADA or IntelliLink software command. The
Hot Line Tag
mode is normally
removed using the same method by which it was applied; however, the HOT LINE TAG
lever can be used to remove electronically set tags as well. The
Hot Line Tag
mode will
only be cleared when all manually set and electronically set tags have been cleared. This
approach satisfies NESC 442.E requirements, which allow local removal of a remotely
set
Hot Line Tag
mode if local indication of the electronically set
Hot Line Tag
mode
is provided.
To locally apply the
Hot Line Tag
mode, pull down on the HOT LINE TAG lever.
It can be “tagged “ in this position using conventional procedures. See Figure 8 on
page 11. To remove the locally set
Hot Line Tag
mode, push up on the HOT LINE TAG
lever.
To remove a SCADA- or IntelliLink software-applied
Hot Line Tag
mode when a local
Hot Line Tag
mode has also been applied, push up on the HOT LINE TAG lever. Then,
pull down and push up on the HOT LINE TAG lever once, without delay. To remove a
SCADA- or IntelliLink software-applied tag when a local
Hot Line Tag
mode has not
been applied, pull down and push up on the HOT LINE TAG lever twice, without delay.
The HOT LINE TAG indicator is located on the protection and control module. See
Figure 9 on page 13. When the
Hot Line Tag
mode is set, the HOT LINE TAG indicator
flashes for a ½ second every 2 seconds. Any trip in the Hot Line Tag profile will be per-
formed as a
Three-Phase Trip
operation. When the
Hot Line Tag
mode is removed,
the HOT LINE TAG indicator is off.
