Step 4: Prepare to monitor the 81-1 function operation. Operation can be verified by monitoring OUT2
(see Figure 292).
Step 5: Connect and apply a 120 Vac, 60-hertz voltage source to terminals C13 (A-phase) and C16
(neutral).
Step 6: Slowly increase the frequency of the applied voltage until OUT2 closes and record the pickup.
Verify that there is an 81-1-Over target on the front-panel display. Slowly decrease the
frequency until OUT2 opens and record the dropout.
Step 7: Repeat Step 6 for the 67 Hz and 69 Hz pickup settings listed in Table 175. Record the results.
Step 8: (Optional.) Repeat steps 1 through 7 for settings groups 1, 2, and 3.
Step 9: (Optional.) Repeat steps 1 through 8 for 81-2, 81-3, 81-4, 81-5, 81-6, 81-7, and 81-8.
