Step 2:
Prepare to monitor the 27P-1 timings. Timing accuracy is verified by measuring the elapsed
time between a sensing voltage change and OUT1 closing.
Step 3:
Connect and apply a 120 Vac, three-phase voltage source to terminals C13 (A-phase), C14 (B-
phase), C15 (C-phase), and C16 (Neutral).
Step 4:
Step the A-phase voltage down to 110 volts. Measure the time delay and record the result.
Step 5:
Repeat step 4 for the 5,000 ms and 10,000 ms time delays of Table 143. Record the results.
Step 6:
(Optional.) Repeat steps 1 through 5 for the B-phase and C-phase voltage inputs. Note: Be sure
to enable proper target for each phase being tested.
Step 7:
(Optional.) Repeat steps 1 through 6 through 6 for settings group 1, 2, and 3.
Step 8:
(Optional.) Repeat steps 1 through 7 for 27P-2, 27P-3, 27P-4, and 27P-5.
