SYSTEM SETUP
— This setting selects an operand that creates a programmable signal to operate a contact output to close

track phase A and the
SWTCH 1 ΦA/3P OPND

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 BAD STATUS
SWITCH 1 ALARM DELAY
pole 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 G60 is in "Programmed" mode and not in local control mode.
