5-6 BE1-50/51B Testing 9252000991 Rev R
Perform preliminary setup:
Time Dial Test
• Connect test setup as shown in Figure 5-1.
• 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.
Perform preliminary setup:
Integrating Reset Test (Applicable Only to 200 Series Relays)
• Connect test setup as shown in Figure 5-1.
• 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 ON (selects integrating reset).
• Set TIME DIAL to 4.5.
• Set CURVE to I.
• Set TIME PICKUP to 0.2.
• Set INST PICKUP to 18.0.
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 0.8 ampere input current to terminals 8 and 9. After the unit trips, remove the input current
for 20 ±0.25 seconds, then reapply the 0.8 ampere input current. Record the elapsed time from
the re-application of input current to the output retrip.
Result: Elapsed time should be 1.55 ±0.3 seconds.
Perform preliminary setup:
Target Test
• 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 voltage source to provide a target current of 1.0 ampere.
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.
