Step 3: Increase the phase voltage source until OUT4 begins pulsing. This should occur immediately
but reaches the maximum width/interval period when the source is raised above approximately
74.48 V.
Step 4: Pulse width at the maximum period should be verified by measuring the elapsed time between
when the contact closes and when it opens. The measured length should be 5 s ±33.3 ms.
Step 5: Pulse interval should be verified by measuring the elapsed time between when a contact opens
and when it closes. The measured length should be 10 s ±50 ms.
Step 6: Decrease the phase voltage source until OUT5 begins pulsing. This should occur immediately
but reaches the maximum width/interval period when the source is raised above approximately
58.89 V.
Step 7: Repeat Steps 4 and 5.
Step 8: (Optional) Repeat Steps 2 through 7 for Settings Group 1, 2, and 3.
Frequency Raise/Lower Proportional Output Verification
Step 1: Use BESTCOMSPlus to monitor the status of OUT2 (Lower) and OUT3 (Raise).
Step 2: Connect a balanced, three-phase voltage source of 69.28 Vpn, 60 Hz to BE1-11g terminals C13
(A-phase), C14 (B-phase), C15 (C-phase), and C16 (neutral). Apply a single-phase, 60-hertz
voltage of 69.28 Vpn, ∠0°, to terminals C17 (Vx-phase) and C18 (Vx-neutral). OUT2 and OUT3
should be open.
Step 3: Slowly increase the frequency of the phase voltage source until OUT2 begins pulsing. This
should occur immediately but reaches the maximum width/interval period when the source is
raised above approximately 60.4 Hz.
Step 4: Pulse width should be verified by measuring the elapsed time between when the contact closes
and when it opens. The measured length should be 10 s ±50 ms.
Step 5: Pulse interval should be verified by measuring the elapsed time between when a contact opens
and when it closes. The measured length should be 5 s ±33.3 ms.
Step 6: Decrease the phase voltage source until OUT5 begins pulsing. This should occur immediately
but reaches the maximum width/interval period when the source is lowered below approximately
59.6 Hz.
Step 7: Repeat Steps 4 and 5.
Step 8: (Optional) Repeat Steps 2 through 5 for Settings Group1, 2, and 3.
Breaker Close Attempts/Sync Fail Activation Delay Verification
Step 1: Use BESTCOMSPlus to verify the settings in Table 236 and set the logic in Figure 316 above.
Step 2: Prepare to monitor the status of OUT1 (Close Breaker) and OUT8 (Sync Fail).
Step 3: Connect a balanced, three-phase voltage source of 69.28 Vpn, 60 Hz to BE1-11g terminals C13
(A-phase), C14 (B-phase), C15 (C-phase), and C16 (neutral). Apply a single-phase, 60-hertz
voltage of 69.28 Vpn, ∠0°, to terminals C17 (Vx-phase) and C18 (Vx-neutral).
Step 4: Connect a contact sensing input to terminals B3 (IN2+) and B4 (IN2-).
Step 5: Apply contact sensing voltage to IN2 to initiate a close attempt and cause OUT1 to close.
CAUTION: Applying voltage above the capabilities of the BE1-11g power supply can cause
irreversible damage to the BE1-11g. Consult the Specifications chapter for more information on
contact input voltage ranges.
Step 6: OUT1 should close two more times for a total of three close attempts. OUT8 should close
approximately 5 seconds after the third close attempt.
Step 7: (Optional.) Repeat Steps 2 through 6 for Settings Group 1, 2, and 3.
