16. Assert logic input 5 (Breaker Connected) at the Incomer 1 relay - at the Incomer 1 relay output relays 5 and
7 should operate; at both Incomer relays the message Transfer Not Ready should be removed from the
display.
17. Momentarily assert logic input 3 (Remote Open) at the Incomer 1 relay - the Incomer 1 breaker should trip
and output relays 5 and 7 should reset; at both Incomer relays the message Transfer Not Ready should be
displayed.
18. Momentarily assert logic input 2 (Remote Close) at the Incomer 1 relay - the Incomer 1 breaker should
close and output relays 5 and 7 should operate; at both Incomer relays the message Transfer Not Ready
should be removed.
19. De-assert logic input 5 (Breaker Connected) at the Incomer 2 relay - at the Incomer 2 relay output relays 5
and 7 should reset; at both Incomer relays the message Transfer Not Ready should be displayed.
20. Assert logic input 5 (Breaker Connected) at the Incomer 2 relay - at the Incomer 2 relay output relays 5 and
7 should operate; at both Incomer relays the message Transfer Not Ready should be removed from the
display.
21. Momentarily assert logic input 3 (Remote Open) at the Incomer 2 relay - the Incomer 2 breaker should trip
and output relays 5 and 7 should reset; at both Incomer relays the message Transfer Not Ready should be
displayed.
22. Momentarily assert logic input 2 (Remote Close) at the Incomer 2 relay - the Incomer 2 breaker should
close and output relays 5 and 7 should operate; at both Incomer relays the message Transfer Not Ready
should be removed from the display.
23. Momentarily assert logic input 2 (Remote Close) at the Bus Tie relay - the Bus Tie breaker should close
and output relays 5 and 7 should operate; at both Incomer relays the Transfer Not Ready message should
be displayed.
24. Momentarily assert logic input 3 (Remote Open) at the Bus Tie relay - the Bus Tie breaker should trip and
output relays 5 and 7 should reset; at both Incomer relays the Transfer Not Ready message should be
removed from the display.
25. Assert logic input 11 (Block Transfer) at the Incomer 1 relay - output relays 5 and 7 should reset; at both
Incomer relays the Transfer Not Ready message should be displayed.
26. De-assert logic input 11 (Block Transfer) at the Incomer 1 relay - output relays 5 and 7 should operate; at
both Incomer relays the Transfer Not Ready message should be removed from the display.
27. Assert logic input 11 (Block Transfer) at the Incomer 2 relay - output relays 5 and 7 should reset; at both
Incomer relays the Transfer Not Ready message should be displayed.
28. De-assert logic input 11 (Block Transfer) at the Incomer 2 relay - output relays 5 and 7 should operate; at
both Incomer relays the Transfer Not Ready message should be removed from the display.
29. Check the Event Recorders in the Incomer 1 and 2 and Bus Tie relays for the correct messages and
sequences, then clear the recorders.
b) LOW VOLTAGE LOGIC
1. Slowly reduce test voltage Source 1 supplying Incomer relay 1. At the pickup voltage of the Line Undervolt-
age 3 feature output relay 4 should operate. At this time the Incomer 2 relay should display the Transfer
Not Ready message.
2. Slowly increase test voltage Source 1. At the reset voltage of the Line Undervoltage 3 feature output relay
4 should reset. At the Incomer 2 relay after the time delay of setpoint Transfer Delay Other Source the
message Transfer Not Ready should be removed from the display.
