Step 3: Use BESTCOMSPlus to open the Protection, Voltage, Undervoltage (27X-1) screen and send
the first row of test settings in Table 145 to the BE1-11g.
Step 4: Prepare to monitor the 27X-1 function operation. Operation can be verified by monitoring OUT2
(see Figure 294).
Step 5: Connect and apply a 120 Vac, a single-phase voltage source to terminals C13 (A-phase) and
C16 (Neutral). Reset the target.
Step 6: Slowly decrease the voltage until OUT2 closes and record the pickup. Verify that there is a 27X-
1-3V0 target on the front-panel display. Slowly increase the A-phase voltage until OUT2 opens
and record the reset. Reset the target.
Step 7: Verify the pickup and dropout accuracy at a pickup setting of 65 V and 20 V as listed in Table
145. 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.
