9252000995 Rev H BE1-50/51B-218/-228 Testing 5-5
 Set CURVE to V.
 Set TIME PICKUP to 1.0.
 Set INST PICKUP to 90.
Step 1. Set voltage source to provide a target current of 1.0 ampere.
Step 2. Read all of Step 3 before beginning Step 3.
Step 3. Apply 4.0 amperes input current to terminals 5 and 6. After the unit trips, remove the input current
for 29 ±0.25 seconds, then reapply the 4.0 amperes input current. Record the elapsed time from
the re-application of input current to the output retrip.
Result: Elapsed time should be 2.08 ±0.4 seconds.
Test Procedure, Models BE1-50/51B-228 (One Ampere Sensing Input)
Time Pickup Test
Perform preliminary setup:
 Connect test setup as shown in Figure 5-1.
 Insure that SW3 switches are set: SW3-1 for the operating frequency, SW3-2 to OFF, SW3-3 to
ON and SW3-4 to ON.
 Set TIME DIAL to 0.0.
 Set CURVE to S
 Set TIME PICKUP to 0.5.
 Set INST PICKUP to 18.0.
Step 1. Slowly increase current to terminals 5 and 6. PICKUP LED should turn RED at a maximum input
current of 0.110 ampere.
Step 2. Decrease input current until PICKUP LED turns GREEN then OFF.
Step 3. Set TIME PICKUP to 0.44.
Step 4. Slowly increase current to terminals 5 and 6. PICKUP LED should change from GREEN to RED
at an input current of 0.426 to 0.454 amperes.
Step 5. Decrease input current until PICKUP LED turns OFF.
INST Pickup Test
Perform preliminary setup:
 Connect test setup as shown in Figure 5-1.
 Insure that SW3 switches are set: SW3-1 for the operating frequency, SW3-2 to OFF, SW3-3 to
ON, and SW3-4 ON.
 Set TIME DIAL to 0.0.
 Set CURVE to S
 Set TIME PICKUP to 3.18.
 Set INST PICKUP to 0.2
Step 1. Slowly increase current to terminals 5 and 6. INST contacts should close at an input current of
0.191 to 0.209 amperes.
Step 2. Decrease input current until INST output contacts open.
Step 3. Set INST PICKUP to 08.
Step 4. Slowly increase current to terminals 5 and 6. INST contacts should close at an input current of
1.563 to 1.637 amperes.
Step 5. Decrease input current until INST output contacts open.
Time Dial Test
Perform preliminary setup:
 Connect test setup as shown in Figure 5-1.
 Insure that SW3 switches are set: SW3-1 for the operating frequency, SW3-2 to OFF, SW3-3 to
ON, and SW3-4 ON.
 Set TIME DIAL to 4.5.
