5-6 BE1-50/51B Testing 9252000991 Rev N
• Ensure that SW3 switches are set correctly: SW3-1 for operating frequency, SW3-2 to OFF (no
instantaneous delay), SW3-3 to OFF (no instantaneous delay (100 series relays) or ABB type
curves selected (200 series relays)), and SW3-4 to OFF (selects instantaneous reset).
• Set TIME DIAL to 4.5.
• Set CURVE to S
• Set TIME PICKUP to 0.2.
• Set INST PICKUP to 18.0.
Step 1. Prepare to apply 0.3 amperes input current to terminals 8 and 9 and record the elapsed time from
when current is applied until TIME output contacts close.
Step 2. Apply the current (step from 0 to 0.3 amperes) and record the elapsed time. Elapsed time should
be 1.754 to 2.084 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
Perform preliminary setup:
• Connect test setup as shown in Figure 5-2.
• Ensure that SW3 switches are set correctly: SW3-1 for operating frequency, SW3-2 to OFF (no
instantaneous delay), SW3-3 to OFF (no instantaneous delay (100 series relays) or ABB type
curves selected (200 series relays)), and SW3-4 to OFF (selects instantaneous reset).
• Set TIME DIAL to 4.5.
• Set CURVE to S
• Set TIME PICKUP to 0.2.
• Set INST PICKUP to 0.2.
Step 1. Set target current source to 1.0 ampere, ac.
Step 2. Apply 1 ampere input current to terminals 8 and 9. Check that both TIME and INST targets
operate.
Step 3. Remove input current and reset targets.
Manual Trip Test
Perform preliminary setup:
• Connect test setup as shown in Figure 5-2.
• Ensure that SW3 switches are set correctly: SW3-1 for operating frequency, SW3-2 to OFF (no
instantaneous delay), SW3-3 to OFF (no instantaneous delay (100 series relays) or ABB type
curves selected (200 series relays)), and SW3-4 to OFF (selects instantaneous reset).
• Set TIME DIAL to 4.5.
• Set CURVE to S
• Set TIME PICKUP to 0.2.
• Set INST PICKUP to 0.2.
Step 1. Set target current source to 1.0 ampere, ac.
Step 2. Apply 0.15 ampere input current to terminals 8 and 9.
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.
CAUTION
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.
