ated options except that the first paragraph of said warranty is replaced by the following:
(1) General: Seller warrants to immediate purchaser or end user for a period of 10
years from the date of shipment that the equipment delivered will be of the kind and
quality specified in the contract description and will be free of defects of workmanship
and material. Should any failure to conform to this warranty appear under proper and

Overview
The S&C Model 6802 Automatic Switch Control can be easily configured for a source-
transfer application that operates two S&C Scada-Mate®or Scada-Mate CX™ Switches.
Only one 6802 Switch Control is required for source-transfer when peer-to-peer
communication with other switch controls is not required. IntelliTeam®SG Automatic
Restoration System software can be used for the 6802 Source-Transfer Application.
IntelliTeam SG automatically handles multiple events, and can transfer multiple times—
back and forth to whichever source is available. Figure 1 shows the two FIC connectors
on the bottom of the enclosure.

transfer application.
Before installation or configuration of the S&C Model 6802 Automatic Switch
Control, review the Installation and Operating Instructions, and the Setting Phase and
Ground Overcurrent Levels Instruction Sheet 1045-530, available at the S&C Website
sandc.com Familiarize yourself with the features, procedures, warnings, settings,
operation, and troubleshooting. The control can be configured in the shop prior to
installation or after installation at the site.
You need to collect basic information about the circuit and location where the
equipment will be installed.
• Obtain the total clearing curves for the preferred- and alternate-source circuit
breakers or other upstream fault-clearing devices, along with other relay settings,
such as reclose times, number of trips, type of trips (instantaneous or delayed), and
reset times.
• Determine if there are any capacity constraints on either source that should prevent
transfer under certain loading conditions.
• Ensure that the voltage sensors on both switches face the substation side of the line.
• Obtain the sensor calibration sheets shipped with the switches. Record the switch
serial numbers.
• Verify that you have the correct software for this switch control application.

Overhead Source-Transfer Software
Use these instructions with software SG6802DOInstaller-3.5.5 or a later
revision.
Step 1
Install SG6802DOInstaller-3.5.5 software on the computer that will be used to program
the 6802 Controls. IntelliLink®Software will be automatically installed.
Step 2
Connect your computer to the switch control with a serial or USB cable. Always use
battery power or a grounded, 3-wire extension cord for your computer and the ac
powered switch control. Your serial or USB port may be damaged if the computer or
switch control is not grounded.
Step 3
Start IntelliLink with Start > Programs > S&C Electric > IntelliLink. IntelliLink will
automatically connect to the 6802 Control and open the Operation screen.
Step 4
On the Setup > General > Time screen, configure the parameters for Daylight
Savings Time Automatic Switchover, Time and Date. On the Setup > General
screen configure the Physical Location and Cabinet Heater settings. Ignore the
Cabinet Heater setting if the control is not powered from a 120-Vac source, because the
heater does not function with sensor power. Enter the serial number for each switch.
Step 5
On the Setup > General > Sensor Configuration screen enable Visual Disconnect
status for Scada-Mate installations. Scada-Mate CX Switches do not have a status
contact for their optional visual disconnect. Enter the sensor calibration data provided for
Switch 1 and Switch 2. Switch 1 is connected to the rear FIC near the mounting bracket,
Switch 2 is connected to the front FIC near the enclosure door.
Step 6
On the Setup > General > Site-Related screen enter the installation-dependent
parameters for voltage. The Loss-of-Voltage Threshold setting can be increased as
reliability and power quality dictate for a particular load. Please review the Setup
Instructions. Instantaneous reclose of an upstream breaker or recloser must be consid-
ered when determining the LOV setting. A voltage loss less than 15 cycles may not be
detected by a 6802 Control. To detect a 15-cycle voltage loss at the 6802 Control, do not
set the Loss-of-Voltage Threshold any lower than 60 volts.
For a phase-to-neutral connected transformer, the Phase Angle Offsets should be set
to zero degrees. For phase-to-neutral transformers, the Phase Angle Offsets should be
set to 30 or 330 degrees. Verify that the Real-Time Data is correct. The correct settings
will result in current in the normal direction and a reasonable power factor. See the
Setup Instructions for further details.
Step 7
On the Setup > General > Fault Detection screen select phase and ground fault
settings according to the time-current clearing curves of the upstream fault-clearing
device. Instruction Sheet 1042-572 Setting Phase and Ground Overcurrent Levels can
assist you in determining these settings. For most installations, the Phase Fault Detection
Current Level should be set at 90% of the minimum trip setting of the upstream recloser
or breaker, and the Fault Duration Time Threshold should be set according to the
fastest clearing time for high-magnitude faults. Ground Fault protection should be set
to coordinate with the time-current curve of the upstream fault-clearing device. The
usual setting is 100% of minimum to trip. Inrush settings should consider the connected
transformer and motor kVA on the load side of the switch, and follow ANSI/IEEE
guidelines.

Step 8
Return to the Operation screen and click CHANGE to Enable Automatic
Operation. On the Setup > General > Automatic Operations screen set Features Enabled
to Sectionalizing + Phase Loss for both switches, or determine the most appropriate
setting for your application, and enable the same feature set for both switches. Enter
settings for all the other parameters. Refer to S&C Instruction Sheet 1045-530 Setup, or
press F1 for detailed information on each parameter. Go to the Validate/Apply screen
and click Apply.
Step 9
Go to the Setup > Communications > DNP screen. If SCADA communication is used,
enter the required parameters. Also enter a non-zero RTU address for the 6802 that
matches the RTU address you enter in the next step. See Instruction Sheet 1045-530 for
more information about communication settings.
Step 10
Go to the Setup > Restoration > IntelliTEAM SG > Team 1 Setup screen. See
Figure 2. Enter a Team ID and set Team Logic to IT-II. Adjust the Return to Normal Timer
if you want to use that function.

Step 11
Configure Rec 1 for Sw 1 and Rec 2 for Sw 2. Switch 1 is connected to the rear
FIC next to the bracket mount, Switch 2 is connected to the front FIC near the
enclosure door. Enter the same RTU Address for both Rec 1 and Rec 2; use the same
RTU Address you entered in Step 10. Specify which switch is Normally Closed and
which is Normally Open. For the Normally Closed switch set the Normal Switch
Function to Src/Sub and the Return to Normal Mode to Close. For the Normally Open
switch set the Normal Switch Function to Tie/Sub and set the Return to Normal Mode
to Close. “Close” defines Return to Normal as a closed transition mode or make-before-
break. At Return to Normal the normally closed switch will close and then the normally
open switch will open—the feeders are temporarily tied together, but there is no outage.

Step 12
Adjust Maximum Capacity.
Step 13
Set the Team Setup to Stopped,if not already set to Stopped. Click OK.Then set it
back to Running and click OK.
Step 14
Wait for the control to go into the Ready mode by watching the LCD on the control.
Step 15
Save a snapshot of the control data. The Save Snapshot command is in the File menu on
the toolbar of the IntelliLink screen.
