Step 4: Prepare to monitor the 81-1 function operation. Operation can be verified by monitoring OUT2

(see Figure 293).

Step 5: Connect and apply a 120 Vac, 60-hertz voltage source to terminals C13 (A-phase) and C16

(neutral).

Step 6: Slowly decrease the frequency of the applied voltage until OUT2 closes and record the pickup.

Verify that there is an 81-1-Under target on the front-panel display. Slowly increase the

frequency until OUT2 opens and record the dropout.

Step 7: Repeat Step 6 for the 46 Hz and 48 Hz pickup settings listed in Table 177. 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.
