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.
HOT LINE TAG ON/OFF Toggle Switch and LED
Indicator
Hot Line Tag is provided for live-line work applications. All
closing operations are disabled when the Hot Line Tag
feature is activated.
Hot Line Tag prevents all closing attempts from the control
and shifts protection to one trip-to-lockout on the composite
curve of the Hot Line Tag definite time and the TCC1 curve
(whichever is faster). Hot Line Tag takes precedence over
Cold Load Pickup, Non-Reclosing, and Fast Trips
Disabled.
Hot Line Tag is activated from either the operator panel
toggle switch, serial communications, or a discrete SCADA
function. All sources must be off to de-activate Hot Line
Tag.
To activate the function from the operator panel, flip toggle
switch up to the ON position. See Figure 7. The LED
indicator illuminates when the function is active.
The Hot Line Tag function may only be reset by the source
which initiates it. For example, if Hot Line Tag is activated at
the operator panel, the reset function is only possible at the
operator panel, and not via SCADA command.
CLOSE CIRCUIT DISABLE
Close Circuit Disable (Figure 7) is a removable fuse that,
when removed from the front operating panel, disables the
close circuit from the control to the recloser. Removing the
fuse from the control disables all electrical closing of the
recloser and provides a physical disconnect to the recloser
closing circuit. As a result, the control cannot perform a
close operation. This disconnect overrides all close
functions and makes a remote or manual close operation
impossible.
Note: When the Close Circuit Disable fuse is removed, the trip
circuit remains active and will trip per the programmed
time current curve for a faulted condition.
TRIP (Lockout) Pushbutton
The TRIP pushbutton (Figure 7) provides front-panel access
to trip (lockout) the recloser. When pressed, the TRIP
pushbutton opens the recloser and locks out the control.
Note: In the event of main microprocessor failure, the trip circuit
can operate independent of the main microprocessor.
CLOSE Pushbutton
When pressed, the CLOSE pushbutton (Figure 7) returns
the control to the initial or home sequence position, closing
the recloser. The control is ready for the start of a new trip/
close sequence.
Note: The Close Malfunction alarm must be reset before
Closing will be allowed.
Note: Pressing the CLOSE pushbutton from the Lockout
position initiates Cold Load Pickup (CLPU) protection, if
the feature is enabled.
The user does have the ability to block COLD LOAD
PICKUP through the LCD menu or by configuring one of
the Option one-touch function keys via the Idea
Workbench feature in ProView.
If the recloser is closed, pushing and holding the CLOSE
pushbutton does not activate the Cold Load Pickup
feature. See Cold Load Pickup in the Control Features
section of this manual.

WARNING: Hazardous voltage. Do not use Hot
Line Tag as a substitute for a visible disconnect.
Always establish a visible disconnect prior to performing
any work requiring a de-energized line. Failure to comply
may cause death, severe personal injury, or equipment
damage. T276.0
IMPORTANT: Hot Line Tag is intended solely for live-line
work applications, such as maintenance, repairs or
improvements to the distribution system, that occur
while the line remains energized.
IMPORTANT: Hot Line Tag activation does not cause
the recloser to trip open. It only prevents the recloser
from closing.
IMPORTANT: If the power save feature is enabled
(default), and more than ten minutes elapses since the
last panel operation, all the LEDs, except HOT LINE TAG
(if active), will turn off.
IMPORTANT: If the CLOSE button is pressed after the
Close Circuit Disable fuse is removed, do not reinstall the
fuse until after the ALARM LED illuminates (within approx-
imately five seconds) to indicate CLOSE MALFUNCTION.
Re-installing the Close Circuit Disable fuse prior to the
CLOSE MALFUNCTION ALARM indication will cause the
control to close the recloser.
