BE1-CDS220 Testing And Maintenance 13-55
Step 5. After pickup occurs, slowly ramp the current down until both OUT1, OUT2, and OUT3 open.
Verify that dropout occurred as specified (95%
±
2%).
Step 6. Repeat Steps 3, 4, and 5 for all values in Table 13-46. Optionally, reconnect the current source
to B-phase (B3, B4) and C-phase (B5, B6) inputs to test the response of all phases for each
succeeding test.
Step 7. (Optional) Repeat steps 3 through 6 for phases B and C of the relay unless each phase was
tested in step 4. If so, skip this step and proceed to Step 8.
Step 8. (Optional) Repeat steps 1 through 7 for the 151 and 251 elements. Use Table 13-48 or 13-49
as a reference for substituting the commands used in Step 1.
Table 13-48. Time Overcurrent 151 Element Test Logic
Replace These Commands With These Commands For 151 Element Tests
SL-51=1,0 SL-151=1,0
SL-VO1=51PT SL-VO1=151PT
SL-VO2=51NT SL-VO2=151NT

Step 9. (Optional) Repeat steps 1 through 8 for the 51, 151, and 251 elements in setting groups 1, 2,
and 3. Use the following information as a guide to program the 51/151/251 elements in higher
order setting groups.
In order to program the pickup of the elements in a higher order setting group, you would
replace the
0 in the S 0 -51P, S 0 -51N, and S 0 -51Q commands in Table 13-45 with a 1, 2, or 3
for setting groups 1, 2, or 3. Or, if your relay is supplied with the HMI option, you can program
each set of values by navigating to the appropriate setting group screen \PROT\SGn\51\51,
where n is equal to the setting group you desire. Refer to the CS/CO-GROUP command in
Section 4,
Protection and Control Functions for more information on changing the active setting
group.
To change from group 0 to group 1, execute the following commands.
CS-GROUP=1 select setting group 1
CO-GROUP=1 execute setting group 1
