Step 2: Prepare to monitor the 59X-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 150 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 up to 215 volts. Measure the time delay and record the result.
Step 5: Repeat step 4 for the 5,000 ms and 10,000 ms time delay settings of Table 135. Record the
results.
Step 6: (Optional.) Repeat steps 1 through 5 for settings group 1, 2, and 3.
Step 7: (Optional.) Repeat steps 1 through 6 for 59X-2, 59X-3, and 59X-4.
Pickup Verification (V1 Mode)
Step 1: Use BESTCOMSPlus to send the operational settings in Table 136 to the BE1-11t. Reset all
targets.
