Step 5: Slowly decrease the frequency of the applied voltage until OUT3 (281) closes. Pickup should
occur 0.01 hertz of the pickup setting. Slowly increase the frequency until OUT3
opens. Dropout should occur at 0.02 hertz above or below the pickup setting.
Step 6: Repeat Step 5 for the 181 (OUT2) and 81 (OUT1) functions.
Step 7: Repeat Step 4.
Step 8: Slowly increase the frequency of the applied voltage until OUT4 (381) closes. Pickup should
occur 0.01 hertz of the pickup setting. Slowly decrease the frequency until OUT4
opens. Dropout should occur at 0.02 hertz above or below the pickup setting.
Step 9: Repeat Step 5 for the 481 (OUT5) and 581 (OUT1) functions.
Step 10: Repeat Steps 5 through 9.
Step 11: (Optional.) Repeat Steps 1 through 11 for Setting Groups 1, 2, and 3.
Time Delay Verification
Step 1: Prepare the x81 functions for time delay testing by transmitting the commands in the first
column (2 second TD) of Table 13-75 to the relay. Commands entered in Tables 13-73 and
13-74 should be retained for this test.

Step 2:
Prepare to monitor the x81 timings. Timing accuracy is verified by measuring the elapsed time
between a frequency change and programmed output closing.
Step 3: Connect and apply a 120 Vac, 60-hertz voltage source to terminals B9 (A-phase) and B12
(Neutral).
Step 4: Step the frequency of the applied voltage down from 60 hertz to a value below the 281
underfrequency setting. Measure the time delay and verify the accuracy of the 281 time delay
setting. Timing accuracy is +5 percent or +3 cycles of the time delay setting.
Step 5: Repeat Step 4 for the 181 (OUT2) and 81 (OUT1) elements.
Step 6: Step the frequency of the applied voltage up from 60 hertz to a value above the 381
overfrequency setting. Measure the time delay and verify the accuracy of the 281 time delay
setting. Timing accuracy is +5 percent or +3 cycles of the time delay setting.
Step 7: Repeat Step 6 for the 481 (OUT5) and 581 (OUT1) elements.
Step 8: Transmit the commands in the second column (5 Second TD) of Table 13-75 to the relay.
Step 9: Repeat Steps 2 through 7 with a time delay setting of 5 seconds.
Step 10: Transmit the commands in the third column (10 Second TD) of Table 13-75 to the relay.
Step 11: Repeat Steps 2 through 7 with a time delay setting of 10 seconds.
Step 12: (Optional.) Repeat Steps 1 through 11 for Setting Groups 1, 2, and 3.
Breaker Failure (50BF/150BF/250BF/350BF)
Purpose:
To verify the operation of the breaker failure (BF) elements.
Reference Commands:
SL-x50BF, S<x>-x50BF
The CDS240 has two types of Breaker Failure Initiate, one being contact only, and the other being current
supervised relay trip initiate. The following tests are for
Contact Only Initiate
