General The following instructions are for eld and shop programming of the S&C Overcurrent
Control. This microprocessor-based control is designed for use on S&C Vista SD Under-
ground Distribution Switchgear to provide fault detection and operation of the resettable
vacuum fault interrupters. Each overcurrent control operates up to two three-pole fault
interrupters. The control is housed in an enclosure mounted to the operating mechanism
enclosure. For vault-mounted style Vista SD units, the overcurrent control enclosure is
fully submersible. The electronics module is removable for programming in the shop.
Programming A personal computer furnished by the user is to be used to input settings, review
settings, and interrogate the event recorder. The software for programming the overcur-
rent control is contained within the control. Two data ports are provided—one on
the enclosure for programming in the eld and another on the electronics module for
programming in the shop. Adapter cables are available from S&C (see Instruction Sheet
695-515A) to connect the computer to the control.
An external power source is required for programming and interrogating the control.
A source of dc power is available from the mouse or USB port on the personal computer.
The adapter cables contain connectors for data and power to use the power available
from the computer.
Description
S&C Instruction Sheet 695-515 5

Power and Sensing Current transformers are provided for each three-pole fault interrupter. These current
transformers provide primary current sensing ranging from 50 to 12,500 amperes. S&C
Vista SD Underground Distribution Switchgear rated above 12.5 kA short circuit will
respond to fault currents above 12.5 kA, but the event log will only record that a fault above
12.5 kA has occurred. The overcurrent control is capable of sensing and responding to
both phase overcurrents and ground overcurrents.
The power derived from the current transformers is used to operate the control and to
charge the trip capacitors that discharge into magnetic latching solenoids to trip the fault
interrupters during a fault. No external power is required for operation of the control in
the field.
Time-Current
Characteristics
The overcurrent control features time-current characteristic (TCC) curves consisting
of phase-overcurrent curves and ground-overcurrent curves. The families of curves are
included as follows:
• S&C standard speed curves (for use in place of conventional “E” rated power fuses
• S&C “K” speed curves (for use in place of conventional “K” rated power fuses)
• Tap fault interrupter curves
• Main fault interrupter curves
• ANSI U.S. and IEC curves per IEEE Standard C37.112-1996 U1, U2, U3, U4, U5, C1, C2,
C3, C4, and C5
The tap and main fault-interrupter TCC curves can be customized into hundreds
of different curves using a variety of instantaneous-pickup settings (discrete choices
from 0.2 kA through 6 kA) and definite-time delay settings (discrete choices from
32 ms through 128 ms). For even more specialized shapes, an instantaneous-pickup
setting can be combined with a definite-time delay setting. The minimum total
clearing time—from initiation of the fault to total clearing—is 40 milliseconds.▲
Settings
(See Appendix E for a
complete list of settings)
The overcurrent control has a phase-overcurrent pickup setting and an independent
ground-overcurrent pickup setting for each three-pole fault interrupter.
The input parameters for both the phase- and ground-overcurrent curves include
minimum pickup levels, instantaneous-pickup levels, and definite-time delays.
Phase-overcurrent pickup settings and ground-overcurrent pickup settings are made
independently. If desired, the ground-overcurrent curve and the instantaneous-
pickup and definite-time-delay attributes can be disabled. When E-speed or K-speed
curves are selected, the ground-overcurrent pickup setting is disabled as are the
instantaneous-pickup and definite-time-delay attributes. An example of how to select set-
tings for the overcurrent control is shown in Appendix D.
A choice of 50- or 60-hertz operation is also offered.
▲The definite-time delay setting will override the instantaneous setting when the definite-time delay setting is
activated before the instantaneous setting.
Description
6 S&C Instruction Sheet 695-515

Event Recording The overcurrent control features an internal event recorder that captures the last
12 fault operations for each fault interrupter. The event log indicates which poles
have experienced a fault, the magnitude of the fault, and whether a ground over-
current was involved. This information can be accessed via a personal computer
connected to the data port of the control.
Self Testing Whenever the overcurrent control is powered up—and then periodically
thereafter—it automatically goes through a self-test procedure to test vital sub-
systems and ensure proper operation. The control checks the trip capacitors,
power-supply voltage, RAM, EEPROM, integrity of the data, and voltage control. It
then ags whatever fails the self-test.
Description
S&C Instruction Sheet 695-515 7

Connecting a Personal Computer
NOTICE
S&C does not recommend removing the S&C Over-
current Control from its enclosure for workbench
programming. The Overcurrent Control is in a submers-
ible enclosure. Opening the enclosure may damage the
sealing gasket. Contact your local S&C Sales Office for
details.
A data port for communications is provided at the top of
the enclosure that houses the overcurrent control. This
data port, which is connected to the electronics module
inside the enclosure, cannot draw power from the control
and must be powered from an external source while in
use. When the data port is in use, the power-connection
points (Pins 1 and 4) power the control. The allowable
voltage range is 4 – 5 Vdc, and the power consumption is
1.8 W nominal, 2.2 W maximum.
Adapter cables are available from S&C (see Instruction
Sheet 695-515A)for connecting the control to auser- furnished
personal computer in the field. These cables provide for both
communications and power.
For Microsoft Windows® users, no special software is
required to communicate with the control. The user interface
is menu driven within the control. Use the HyperTerminal
program provided with Microsoft Windows or other
terminal emulator program to set or interrogate the control.
Microsoft Windows Vista™, Windows®7, and Windows®8
users will have to install a terminal emulator program. See
Appendix C for further instructions.
Setting the Communication Parameters
Set the communication parameters shown in Appendix B.
Refer to Appendix C for additional instructions regarding
terminal emulation programs.

Fault Interrupters 1
and 2
Each overcurrent control is capable of operating up to two fault interrupters. To
differentiate between the two fault interrupters, the programming software refers to
Fault Interrupter 1 and Fault Interrupter 2. If the control is operating two fault inter-
rupters, the fault interrupter to the left of the control (as you are facing the front of the
switchgear) is Fault Interrupter 1, and the fault interrupter to the right of the control is
Fault Interrupter 2. If there is only one fault interrupter, it is Fault Interrupter 2.

The overcurrent control stores a nonvolatile short event report each time it issues a trip
pulse. The short event report contains the following information:
The faulted pole(s) and whether ground was involved. The “target” (X) logic is as
follows:
1. Target any faulted poles that caused a trip.
2. Target any phase faulted pole with current greater than the phase time overcurrent
pickup setting.

Press <ENTER> for menu
NOTE: The “X” targets are used under fault conditions. In test mode, fault poles are ran-
domly selected.
3. Target the ground-faulted pole if ground current is greater than the ground pickup
setting or if ground current is greater than or equal to 50A and greater than 10% of the
maximum phase current.
4. If only one target is declared from the previous logic, target the faulted pole (of the
remaining three with the highest current).
The primary RMS magnitude of each pole and ground current. Current greater than
14,500 amperes will be reported as “>14500”.
The event report is reset when the fault-interrupter settings are changed and saved.

Self-Test Report
Viewing the Self-Test
Report
The Overcurrent control tests vital subsystems upon power up and periodically there-
after to ensure proper operation. To view the self-test report, select the View Relay
Self-Test option from the View menu for the selected fault interrupter.

Response to Self-Test
Failure
The following denes each of the self tests and the control’s response to a self-test
failure. The control displays the above screen example when none of the self-tests have
failed. Actual values may vary.
FID
The FID indicates the model, rmware version, and rmware date code.
Trip Caps
The status of the trip capacitors is reported for each fault-interrupter pole. If the trip
capacitors are not charged to at least 50 volts, a “low” condition is reported. The control
cannot issue a trip until the capacitors are fully charged. The capacitors charge from
either the CTs or port power. If the control indicates “low” when no trip condition exists,
the voltage supplied to the communication port is less than 4 volts or the control is defec-
tive and should be replaced.
Supply Voltage
The control periodically checks the voltage of each power supply and compares the
results with failure thresholds. The self-test report displays the measured values.
Protection is disabled and an “F” is placed next to the displayed value if it falls outside the
failure threshold. This self-test also detects gross A/D converter failures.

Self-Test Report
RAM
The RAM self-test veries proper operation of the read/write memory. This test periodi-
cally performs a nondestructive write/read to successive blocks of RAM to determine
whether a RAM failure has occurred. A failure occurs if the expected data are not read
back from the RAM. In this case, protection is disabled and “fail” is reported.
Flash
The Flash self-test veries the integrity of the data contained in system program Flash. If
Flash is corrupted, protection is disabled and “fail” is reported.
CR-RAM
Areas of RAM containing constant data that have been copied from EEPROM are periodi-
cally examined to verify their integrity. If this critical RAM has been corrupted, protection
is disabled and “fail” is reported.
EEPROM
The EEPROM self-test veries the integrity of data contained in EEPROM. EEPROM self-
test failures are handled differently because self-test failures and control settings are both
stored in EEPROM. Following an EEPROM self-test failure, factory-default settings are
restored and protection is enabled. The message “Relay enabled using default settings” is
displayed at the top of each menu. If the EEPROM failure persists (i.e., if default settings
cannot be stored in EEPROM), a self-test failure is also generated.
Voltage Control
This logic monitors the power shunt circuitry in the power supply. On power up, each
phase magnitude is averaged for 0.5 seconds. If the average is greater than or equal to 50
amperes and the associated trip capacitor is not charged, the CT power circuit is defec-
tive and a failure is declared.
Self-Test Failures
and Warnings
The following screen is an example of a self-test screen. The +5-volt power supply voltage
is agged with an “F”, and “Relay Disabled” appears above each menu.
The control records self-test failures in EEPROM and remains disabled until power
is removed and restored. When power is restored, the self-test is repeated. If no failure
occurs, the failure indication changes to “warn”—or “W” in the case of a power supply—
and protection is enabled.
