Perform preliminary setup:
Manual Trip Test
•
Connect test setup as shown in Figure 5-2 (BE1-50/51B-214), Figure 5-4 (BE1-50/51B-215), or
Figure 5-6 (BE1-50/51B-223).
•
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.
•
Set CURVE to S
•
Set TIME PICKUP to 1.0.
•
Set INST PICKUP to 01.
WARNING!
Trip circuit voltage is present at the front panel test points. When shorting the
test points, use insulated jumpers to avoid contact with these voltages.
Step 1. Set voltage source to provide a target current of 1.0 ampere.
Step 2. Apply 0.9 ampere input current to terminals 5 and 6. (0.9 ampere provides input power but stays
below pickup.)
Step 3. Connect a jumper between TIME MANUAL TRIP test points. Check that TIME target operates.
Step 4. Connect a jumper between INST MANUAL TRIP test points. Check that INST target operates.
Step 5. Reset targets.
Perform preliminary setup:
Integrating Reset Test
•
Connect test setup as shown in Figure 5-1 (BE1-50/51B-214), Figure 5-3 (BE1-50/51B-215), or
Figure 5-5 (BE1-50/51B-223).
•
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 9.9.
•
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, Model BE1-50/51B-225 (One Ampere Sensing Input)
Perform preliminary setup:
Time Pickup Test
•
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.
