BE1-50/51B-214/-215/-223/-225 Testing
5-5
Test Procedure, Models BE1-50/51B-214/-215/-223 (Five Ampere Sensing Input)
Perform preliminary setup:
Time 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 to ON.
•
Set TIME DIAL to 0.0.
•
Set CURVE to S
•
Set TIME PICKUP to 0.5.
•
Set INST PICKUP to 90.
Step 1. Slowly increase current to terminals 5 and 6. PICKUP LED should turn RED at a maximum input
current of 0.550 ampere.
Step 2. Decrease input current until PICKUP LED turns GREEN then OFF.
Step 3. Set TIME PICKUP to 2.2.
Step 4. Slowly increase current to terminals 5 and 6. PICKUP LED should change from GREEN to RED
at an input current of 2.131 to 2.269 amperes.
Step 5. Decrease input current until PICKUP LED turns OFF.
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
NOTE
When testing TIME overcurrent functions, INST PICKUP settings of 00 will affect
the calibration of the TIME functions. TIME PICKUP settings of 00 also affect
INST functions.
