Step 2: Use BESTCOMSPlus to configure the BESTlogicPlus programmable logic shown in Figure 293.
•
Blocking is disabled.
•
OUT1 closes for 27P-1 Trip.
•
OUT2 closes for 27P-1 Pickup.
•
Fault recording is enabled.
Step 3: Use BESTCOMSPlus to open the Protection, Voltage, Undervoltage (27P-1) screen and send
the first row of test settings in Table 142 to the BE1-11g.
Step 4: Prepare to monitor the 27P-1 function operation. Operation can be verified by monitoring OUT2
(see Figure 293).
Step 5: Connect and apply a 240 Vac, three-phase voltage source to terminals C13 (A-phase), C14 (B-
phase), C15 (C-phase), and C16 (Neutral).
Step 6: Slowly decrease the A-phase voltage until OUT2 closes and record the pickup. Verify that there
is a 27P-1-A 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 reset accuracy at 120 Vac for a pickup setting of 115 V and 70 Vac for a
pickup setting of 65 V as listed in Table 142. Record the results.
Step 8: (Optional.) Repeat steps 1 through 7 for the B-phase and C-phase voltage inputs. Note: Be sure
to enable proper target for each phase being tested.
Step 9: (Optional.) Repeat steps 1 through 8 for settings group 1, 2, and 3.
Step 10: (Optional.) Repeat steps 1 through 9 for 27P-2, 27P-3, 27P-4, and 27P-5.
Timing Verification
Step 1: Use BESTCOMSPlus to open the Protection, Voltage, Undervoltage (27P-1) screen and send
the first row of test settings in Table 143 to the BE1-11g for settings group 0.
