SL-N=27X,59/159X
Sets 27/59/159X as custom logic name
SL-47=0
Disables 47
SL-27X=2,0
Enables 27X (3E0), disables blocking
SL-59X=2,0
Enables 59X/159X(3E0), disables blocking
SL-159X=2,0
Enables 159X(3E0), disables blocking
SL-VO1=27XT+59XT/159XT
Enables OUT1 to close for 27X and 59X/159X
trip
SL-V02=159XT
Enables OUT2 to close for 159X trip
SG-TRIG=27XT+59XT+159XT,

Step 2 Using Table 13-56 as a guide, transmit the first row of setting commands (highest 27X PU, lowest
59XPU/159XPU) to the relay.

S0-27X=50,50ms
S0-59X/159X=60,50ms
Sets 27X PU at 50V, 59X/159X at 60V, TD
at min
S0-27X=20,50ms
S0-59X/159X=30,50ms
Sets 27X PU at 20V, 59X/159X at 30V, TD

S0-27X=5,50ms
S0-59X/159X=10,50ms
Sets 27X PU at 5 V, 59X/159X at 10V, TD
at min
Step 3 Prepare to monitor the 59X/159X function operation. Operation can be verified by monitoring
OUT1(OUT2 for 159X).
Step 4 Connect and apply a single-phase, 55 Vac voltage source to terminals C13 (polarity) and C16
(non-polarity). Refer to Figure 13-1 for terminal locations.
Step 5 Slowly decrease the voltage until OUT1 closes. Pickup should occur 2 percent or 1 volt
of the 27X pickup setting. Slowly increase the voltage until OUT1 opens. Dropoiut should occur
between 102 and 103 percent of the actual pickup value. Verify the 27NTarget on the HMI and
reset.
Step 6
Continue increasing the voltage until OUT1 closes. Pickup should occur 2 percent or 1 volt
of the pickup setting. Slowly reduce the voltage until OUT1 opens. Dropout should occur between
97 and 98 percent of the actual pickup value. Verify the 59N Target on the HMI>
Step 7 Verify the pickup and dropout accuracy of the middle and upper pickup settings in Table 13-53
Step 8 (Optional) Repeat Steps 2 through 7 for the B-phase and C-phase voltage inputs.
Step 9 (Optional) Repeat Steps 2 through 8 for setting groups 1, 2, and 3.
