BE1-50/51B-Testing

Test Procedure, Models BE1-50/51B-X01, -X02, and -X03 (One Ampere Sensing Input)

Time Pickup Test

Perform preliminary setup:

Connect test setup as shown in Figure 5-1.

Insure that SW8 switches are set correctly: SW8-1 for operating frequency, SW8-2 to OFF (no
instantaneous delay), SW8-3 to OFF (no instantaneous delay (100 series relays) or ABB type curves
selected (200 series relays) ), and SW8-4 to OFF (selects instantaneous reset).

Set TIME DIAL to 0.0.

Set CURVE to S

Set TIME PICKUP to 0.1.

Set INST PICKUP to 18.0.

Step 1. Slowly increase current to terminals 8 and 9.  PICKUP LED should turn ON at a maximum input

current of 0.11 ampere.

Step 2. Decrease input current until PICKUP LED turns OFF.

Step 3. Set TIME PICKUP to 0.44

Step 4. Slowly increase current to terminals 8 and 9.  PICKUP LED should turn ON at an input current of

0.426 to 0.454 ampere.

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 SW8 switches are set correctly: SW8-1 for operating frequency, SW8-2 to OFF (no
instantaneous delay), SW8-3 to OFF (no instantaneous delay (100 series relays) or ABB type curves
selected (200 series relays) ), and SW8-4 to OFF (selects instantaneous reset).

Set TIME DIAL to 0.0.

Set CURVE to S

Set TIME PICKUP to 3.02.

Set INST PICKUP to 0.2.

Step 1. Slowly increase current to terminals 8 and 9.  INST contacts should close at an input current of

0.191 to 0.209 ampere.

Step 2. Decrease input current until INST output contacts open.

Step 3. Set INST PICKUP to 1.6.

Step 4. Slowly increase current to terminals 8 and 9.  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.
