Figure 8. The Setup>General>Sensor Configuration screen (6801 switch control shown).

This screen allows entering calibration data for S&C Scada-Mate® Switching Systems;

automated Omni-Rupter® Switches; and PME, PMH, or Vista Underground Distribution

Switchgear sensors. See Figure 8. The switch control uses this data to calibrate sensor

input to the voltage and current amplitude accuracy specied for S&C sensors.

Current (Magnitude/Phase) & Voltage (Magnitude/Phase) on

Poles 1, 2, and 3

S&C sensors are factory-calibrated. The sensor ratios are stamped on each sensor and

are provided in the information sheet shipped with the switch. The number of sensors

must be selected before entering calibration factors. Ratios must be entered on this

screen to obtain accurate voltage and current measurements. Each eld already has the

approximate default value to reduce the number of keystrokes needed to enter data. The

switch control ignores values for any pole not specied in the Voltage Sensors Present

setting on the Setup>General>Site-Related screen. Store the calibration data sheet in

the control-door pocket for future reference.

NOTICE

Ratios must be entered for phase B when phases A, B, and C are measured. The

phase B ratios are used to adjust all voltage scales for 15-, 25-, or 35-kV systems.

This screen may also include the following fields:

Switch Visual Disconnect Contacts (only applicable to SG6801, SG6801E33, and

SG6802DO software)

All Scada-Mate Switches equipped with R2 switch operators have visual-disconnect

contacts. Visual-disconnect contacts are optional with the R1 switch operator. When

the switch has visual-disconnect contacts, select the Present option for this setpoint.

When the visual-disconnect contacts are open, the ERROR DETECTED indicator on the

faceplate is on, and the Logs>Historic Log screen indicates a Not Ready condition and a

Disconnect Active condition. These conditions clear when the switch visual disconnect

is manually closed. Scada-Mate CX™ Switching Systems do not have visual-disconnect

contacts. When the switch does not have visual disconnect contacts, select the Not

Present option (default) for this setpoint.

Note: When used in an IntelliTeam SG Automatic Restoration System, select the Not

Present setpoint when the switch does not have visual disconnect contacts. This includes

all Scada-Mate CX switches and some Scada-Mate switches with the R1 switch operator.
