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 .
