5.4 SYSTEM SETUP 5 SETTINGS
5
• SWITCH 1 OPEN: This setting selects an operand that creates a programmable signal to operate a contact output to
open disconnect switch 1.
• SWITCH 1 BLK OPEN: This setting selects an operand that prevents opening of the disconnect switch. This setting
can be used for select-before-operate functionality or to block operation from a panel switch or from SCADA.
• SWITCH 1 CLOSE: This setting selects an operand that creates a programmable signal to operate a contact output to
close disconnect switch 1.
• SWITCH 1 BLK CLOSE: This setting selects an operand that prevents closing of the disconnect switch. This setting
can be used for select-before-operate functionality or to block operation from a panel switch or from SCADA.
• SWTCH 1 ΦA/3P CLSD: This setting selects an operand, usually a contact input connected to a disconnect switch
auxiliary position tracking mechanism. This input should be a normally-open 89/a status input to create a logic 1 when
the disconnect switch is closed. If the
SWITCH 1 MODE setting is selected as “3-Pole”, this setting selects a single input
as the operand used to track the disconnect switch open or closed position. If the mode is selected as “1-Pole”, the
input mentioned above is used to track phase A and the SWITCH 1 ΦB and SWITCH 1 ΦC settings select operands to
track phases B and C, respectively.
• SWTCH 1 ΦA/3P OPND: This setting selects an operand, usually a contact input, that should be a normally-closed 89/
b status input to create a logic 1 when the disconnect switch is open. If a separate 89/b contact input is not available,
then an inverted 89/a status signal can be used.
• SWITCH 1 ΦB CLOSED: If the mode is selected as three-pole, this setting has no function. If the mode is selected as
single-pole, this input is used to track the disconnect switch phase B closed position as above for phase A.
• SWITCH 1 ΦB OPENED: If the mode is selected as three-pole, this setting has no function. If the mode is selected as
single-pole, this input is used to track the disconnect switch phase B opened position as above for phase A.
• SWITCH 1 ΦC CLOSED: If the mode is selected as three-pole, this setting has no function. If the mode is selected as
single-pole, this input is used to track the disconnect switch phase C closed position as above for phase A.
• SWITCH 1 ΦC OPENED: If the mode is selected as three-pole, this setting has no function. If the mode is selected as
single-pole, this input is used to track the disconnect switch phase C opened position as above for phase A.
• SWITCH 1 Toperate: This setting specifies the required interval to overcome transient disagreement between the 89/a
and 89/b auxiliary contacts during disconnect switch operation. If transient disagreement still exists after this time has
expired, the
SWITCH 1 BAD STATUS FlexLogic operand is asserted from alarm or blocking purposes.
• SWITCH 1 ALARM DELAY: This setting specifies the delay interval during which a disagreement of status among the
three-pole position tracking operands will not declare a pole disagreement. This allows for non-simultaneous operation
of the poles.
IEC 61850 functionality is permitted when the C30 is in “Programmed” mode and not in the local control mode.
