Step 3: Prepare to monitor 66 function operation. Operation can be verified by monitoring OUT1
(Starting), OUT2 (Stopped), OUT3 (Start Blocked), and OUT4 (Start Blocked Removed). See
Error! Reference source not found.. The test sequence is illustrated in Figure 72-2.

Step 4: Connect a three-phase current source to terminals D1 and D2 (IA), D3 and D4 (IB), and D5 and
D6 (IC).
Step 5: Apply 10 Aac three-phase current for approximately one minute (simulate motor starting). Note
that this is the first start. Verify that OUT1 (Starting) closes and OUT2 (Stopped) opens. Start
the timer when OUT1 (Starting) closes. The timer will be stopped when OUT4 (Start Blocked
Removed) closes in step 9. The expected timing is 360 seconds.
Step 6: Remove three-phase current for approximately one minute. Verify that OUT1 (Starting) opens
and OUT2 (Stopped) closes.
