Step 4: Prepare to monitor the 27X-1 function operation. Operation can be verified by monitoring OUT2
(see Figure 283).
Step 5: Connect and apply a 120 Vac, single-phase voltage source to the Vx input, terminals C17
(polarity) and C18 (non-polarity).
Step 6: Slowly decrease the voltage until OUT2 closes and record the pickup. Verify that there is a 27X-
1-AUX target on the front-panel display. Slowly increase the voltage until OUT2 opens and
record the reset. Reset the target.
Step 7: Verify the pickup and reset accuracy at 70 Vac for a pickup setting of 65 V and 25 Vac for a
pickup setting of 20 V as listed in Table 149. Record the results.
Step 8: (Optional.) Repeat steps 1 through 7 for the B-phase and C-phase voltage inputs.
Step 9: (Optional.) Repeat steps 1 through 8 for settings group 1, 2, and 3.
Step 10: (Optional.) Repeat steps 1 through 9 for 27X-2, 27X-3, and 27X-4.
