Step 2: Prepare to monitor the 27X-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, single-phase voltage source to terminals C17 (polarity) and C18
(non-polarity).
Step 4: Step the 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 delay settings of Table 150. 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 27X-2, 27X-3, and 27X-4.
