SYSTEM SETUP
SWITCH 1 BLK OPEN
setting can be used for blocking disconnect switch opening for instance when switchyard monitoring indicates current
exceeding the switch's interrupting rating can be flowing through the switch.
— This setting selects an operand that when activated, and unless blocked, initiates the disconnect switch
SWITCH 1 CLOSE
1 close command.
SWITCH 1 BLK CLOSE
setting can be used for blocking disconnect switch closing, for instance to prevent closing into a closed ground switch.
SWTCH 1 ΦA/3P CLSD
position tracking mechanism. This input is for a normally-open 89/a status input that creates a logic 1 when the
disconnect switch is closed. If the
the operand used to track the disconnect switch open or closed position. If the mode is selected as "1-Pole," the input
mentioned is used to track phase A and the
C, respectively.
SWTCH 1 ΦA/3P OPND
input that creates 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
pole, this input is used to track the disconnect switch phase B closed position as outlined for phase A.
SWITCH 1 ΦB OPENED
pole, this input is used to track the disconnect switch phase B opened position as outlined for phase A.
SWITCH 1 ΦC CLOSED
pole, this input is used to track the disconnect switch phase C closed position as outlined for phase A.

SWITCH 1 ΦC OPENED
pole, this input is used to track the disconnect switch phase C opened position as outlined for phase A.
SWITCH 1 TOPERATE
and 89/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
position tracking operands do not declare a pole disagreement. This allows for non-simultaneous operation of the poles.
IEC 61850 functionality is permitted when the D60 is in "Programmed" mode and not in local control mode.

— This setting selects an operand that prevents initiation of the disconnect switch 1 command. This
— This setting selects an operand that prevents initiation of disconnect switch 1 close commands. This
— This setting selects an operand, usually a contact input connected to a disconnect switch auxiliary
SWITCH 1 MODE
SWITCH 1 ΦB
— This setting selects an operand, usually a contact input, that is for a normally-closed 89/b status

— If the mode is selected as three-pole, this setting has no function. If the mode is selected as single-
— This setting specifies the required interval to overcome transient disagreement between the 89/a
FlexLogic operand is asserted for alarm or blocking purposes.
— This setting specifies the delay interval during which a disagreement of status among the pole
setting is selected as "3-Pole," this setting selects a single 89/a input as
and settings select operands to track phases B and
