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 when the relay powers up and
synchronizes to the 3-bit input.
Same set of operands as shown above for SELECTOR 1
