Step 2: Use BESTCOMSPlus to configure the BESTlogicPlus Programmable Logic shown in

Figure 310.

• Blocking is disabled.

• OUT1 closes for 32-1 Trip.

• OUT2 closes for 32-1 Pickup.

• Fault recording is enabled.

Forward Tripping Direction (Overpower)

Step 1: Using Table 223 as a guide, send the 32-1 settings to the BE1-11g. Prior to each directional

test, reset the BE1-11g targets from the previous test.

Step 2: Connect and apply a 100 Vac, three-phase voltage source at nominal frequency to terminals

C13 (A-phase), C14 (B-phase), C15 (C-phase), and C16 (neutral). Connect a variable ac

current source to terminals D1 (A-phase polarity) and D2 (A-phase non-polarity).

Step 3: Set A-phase current in phase with the voltage and slowly increase the current from 0 amps until

OUT2 closes and record the pickup. Verify the 32-1-A-Over target on the front-panel display.

Decrease A-phase current until OUT2 opens and record the dropout. Pickup will occur within

±3% of the three-phase 32-1 pickup setting divided by 3 (500 watts = 5 amps, 100 volts, 0

degrees I lag E)/3. See the Power (32) Protection chapter for details on single phase and total

power operation.

Step 4: With the BE1-11g picked up (OUT2 closed), change the angle of the applied current to lag the

voltage by 180 degrees and verify that OUT2 opens. This verifies that the 32-1 function is

operating in the forward trip direction and not in the reverse direction.

Step 5: Repeat Steps 1 through 4 for the 1,000 W and 2,000 W pickup settings in Table 223. Record

the results.

Step 6: (Optional.) Repeat Steps 1 through 5 for B-phase and C-phase currents. (Consult the Power

(32) Protection chapter for operating details).

Step 7: (Optional.) Repeat Steps 1 through 6 using 32-2 in place of 32-1.
