Operand description
Source 1 VT neutral wire open detected. When the VT is connected in Delta,
do not enable this function because there is no neutral wire for Delta
connected VT.

Disconnect switch 1 is closed
Disconnect switch 1 is open
Disconnect switch 1 has discrepancy
Disconnect switch 1 trouble alarm
Disconnect switch 1 phase A is closed
Disconnect switch 1 phase A is open
Disconnect switch 1 phase A bad status is detected (discrepancy between
the 89/a and 89/b contacts)
Disconnect switch 1 phase A intermediate status is detected (transition from
one position to another)
Disconnect switch 1 phase B is closed
Disconnect switch 1 phase B is open
Disconnect switch 1 phase B bad status is detected (discrepancy between
the 89/a and 89/b contacts)
Disconnect switch 1 phase B intermediate status is detected (transition from
one position to another)
Disconnect switch 1 phase C is closed
Disconnect switch 1 phase C is open
Disconnect switch 1 phase C bad status is detected (discrepancy between
the 89/a and 89/b contacts)
Disconnect switch 1 phase C intermediate status is detected (transition from
one position to another)
Disconnect switch 1 bad status is detected on any pole
Same set of operands as shown for SWITCH 1
