SAFETY FOR LIFE

S280-79-10

NON RECLOSING

Non-reclosing mode disables any automatic reclosing operations. Non-reclosing does not alter the active TCC. The feature is activated by pressing the CHANGE/LAMP TEST key, then pressing the NON RECLOSING key. The red indicator illuminates.

SUPERVISORY BLOCKED

Supervisory Blocked disables supervisory SCADA and the interface software; remote SCADA remains active. Operational data and metering information are available while the control is in the SUPERVISORY BLOCKED position. The TRIP and CLOSE pushbuttons are active independently of the SUPERVISORY BLOCKED function.

Activation of the feature is restricted to the operator panel keypad by pressing the CHANGE/LAMP TEST key, then pressing the SUPERVISORY BLOCKED key.

COLD LOAD PICKUP BLOCKED

The Cold Load Pickup feature is blocked while the COLD LOAD PICKUP BLOCKED is active. When CLPU is not blocked, the control utilizes the Cold Load Pickup TCC, reclose interval, operations to lockout and minimum trip settings in lieu of the normal first operation protection settings.

Note: The Cold Load Pickup Blocked key is replaced by the SENSITIVE GROUND FAULT key on international controls.

BATTERY TEST

Depressing the BATTERY TEST key performs a control battery test. The red indicator illuminates and turns off automatically when the control has finished performing the test. Refer to the Battery Test Procedure section of these instructions for further details on testing the control battery.

FAST TRIPS DISABLED

Fast Trips Disabled commands the control to use the programmed Fast Trips Disabled time-current curve for all tripping operations.

ALTERNATE PROFILE Indicator/Key

The control has four separate protection profiles; a normal profile, and Alternate Profiles 1, 2, and 3. Each profile changes all protection parameters for the control. Except for the normal profile, each has an indication and selection key. During control operation, if the three alternate profile indicator lights are not illuminated, the normal profile is active.

To select an alternate profile, press the CHANGE/LAMP TEST key, then press the desired alternate profile. To return to the normal profile, simply turn off the active alternate profile. These functions can also be operated remotely via communications interfaces.

Note: Program all protection profiles. Program unused alternate profiles should be programmed with the same setting as one of the applicable profiles. Default settings on unused alternate profiles can cause unnecessary outages if they are below normal system requirements.

Note: The minimum trip values for each protection profile are shown on Screens 32 and 33 of the LCD display. Check these minimum trip values prior to changing an alternate profile to avoid misoperation of the control under load conditions.

Note: On Form 5 UDP controls, Alternate Profile 3 is replaced with SWITCH MODE.

HOT LINE TAG Switch

!

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

Hot Line Tag is provided for live-line work applications. All closing operations are disabled when the Hot Line Tag feature is activated. While active, the control utilizes an independent, user-selectable time-current curve for trip operations.

IMPORTANT: Hot Line Tag activation does not cause the recloser to trip open. It only prevents the recloser from closing.

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.

The Hot Line Tag feature (Figure 8) consists of a toggle switch and an LED indicator which illuminates when the function is active. When active, Hot Line Tag prevents all closing attempts and shifts protection to one trip to lockout on the programmed time-current curve. The Hot Line Tag function takes precedence over Cold Load Pickup, Non Reclosing, and Fast Trips Disabled.

Activation is accomplished by placing the operator panel toggle switch to the ON position, or via SCADA command. Hot Line Tag is activated from the operator panel, communication Port 2, communication Port 3, or a Discrete Interface Module (DIF). All sources must be off to de-activate Hot Line Tag.

The Hot Line Tag feature may only be reset by the source which initiates the function. For example, if Hot Line Tag is activated at the operator panel, resetting the function is only possible at the operator panel, and not via SCADA command. For SCADA, Hot Line Tag must be disabled via the same port number where Hot Line Tag was originally enabled.
