5.4 SYSTEM SETUP
• SWITCH 1 OPEN: This setting selects an operand that creates a programmable signal to operate an output relay 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 an output relay 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 52/a status input to create a logic 1 when
the disconnect switch is closed. If the
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
track phases B and C, respectively.
SWITCH 1 ΦA/3P OPND: This setting selects an operand, usually a contact input, that should be a normally-closed
•
52/b status input to create a logic 1 when the disconnect switch is open. If a separate 52/b contact input is not avail-
able, then the inverted
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 52/a
and 52/b auxiliary contacts during disconnect switch operation. If transient disagreement still exists after this time has
expired, the
SWITCH 1 BAD STATUS
• 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 F35 is in "Programmed" mode and not in the local control mode.
