OPERAND DESCRIPTION
Restricted ground fault 1 has picked up
Restricted ground fault 1 has operated
Restricted ground fault 1 has dropped out
Same set of operands as shown for RESTD GND FT1
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
