Perform preliminary setup:
INST Pickup 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 0.0.
•
Set CURVE to S
•
Set TIME PICKUP to 15.9.
•
Set INST PICKUP to 01.
Step 1. Slowly increase current to terminals 5 and 6. INST contacts should close at an input current of
0.955 to 1.045 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
7.815 to 8.185 amperes.
Step 5. Decrease input current until INST output contacts open.
Perform preliminary setup:
Time Dial 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 4.5.
•
Set CURVE to S
•
Set TIME PICKUP to 1.0.
•
Set INST PICKUP to 90.
Step 1. Prepare to apply 1.5 amperes input current to terminals 5 and 6 and record the elapsed time from
when current is applied until TIME output contacts close.
Step 2. Apply the current (step from 0 to 1.5 amperes) and record the elapsed time. Elapsed time should
be 0.345 to 0.424 seconds. (This tolerance is greater than ±2% because it is the accumulation of
both pickup and timing tolerances.)
Step 3. Remove input current.

Target 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 90.
Step 1. Set voltage source to provide a target current of 1.0 ampere.
Step 2. Apply 5 amperes input current to terminals 5 and 6. Check that the TIME target operates.
Step 3. Remove input current and reset target.
Step 4. Set TIME PICKUP to 15.9 and set INST PICKUP to 01.
Step 5. Set voltage source to provide a target current of 1.0 ampere.
Step 6. Apply 5 amperes input current to terminals 5 and 6. Check that the INST target operates.
Step 7. Remove input current and reset targets.
