OPERAND DESCRIPTION
Selector switch 1 is in Position Y (mutually exclusive operands)
First bit of the 3-bit word encoding position of selector 1
Second bit of the 3-bit word encoding position of selector 1
Third bit of the 3-bit word encoding position of selector 1
Position of selector 1 has been pre-selected with the stepping up control
input but not acknowledged
Position of selector 1 has been pre-selected with the 3-bit control input but
not acknowledged
Position of selector 1 has been pre-selected but not acknowledged
Position of selector switch 1 is undetermined or restored from memory when
the relay powers up and synchronizes to the three-bit input
Same set of operands as shown above for SELECTOR 1
Setting group 1 is active
Setting group 2 is active
Setting group 3 is active
Setting group 4 is active
Setting group 5 is active
Setting group 6 is active
Source 1 disturbance detector has operated
Source 2 disturbance detector has operated
Source 3 disturbance detector has operated
Source 4 disturbance detector has operated
Source 5 disturbance detector has operated
Source 6 disturbance detector has operated
Source 1 VT fuse failure detector has operated
Source 1 VT fuse failure detector has dropped out
Source 1 has lost voltage signals (V2 below 10% and V1 below 5%
of nominal)
Source 1 VT neutral wire open detected.When the VT is connected in Delta,
this function should not be enabled because there is no neutral wire for Delta
connected VT.

one position to another)
Disconnect switch 1 phase B is closed
Disconnect switch 1 phase B is open
