BE1-50/51B-217 Testing
5-5
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.
Manual Trip Test
Perform preliminary setup:
Connect test setup as shown in Figure 5-2.
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), and SW8-4 to OFF (selects
instantaneous reset).
Set TIME DIAL to 4.5.
Set CURVE to S
Set TIME PICKUP to 1.0.
Set INST PICKUP to 01.
Step 1. Set target current source to 1.0 ampere, ac.
Step 2. Apply 0.9 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.
Integrating Reset Test
Perform preliminary setup:
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), and SW8-4 to ON (selects
integrating reset).
Set TIME DIAL to 4.5.
Set CURVE to I.
Set TIME PICKUP to 1.0.
Set INST PICKUP to 90.
Step 1. Set target current source to 1.0 ampere, ac.
Step 2. Read all of Step 3 before beginning Step 3.
Step 3. Apply 4.0 amperes input current to terminals 8 and 9. After the unit trips, remove the input
current for 20 ±0.25 seconds, then reapply the 4.0 amperes input current. Record the elapsed
time from the reapplication of input current to the output retrip.
Result: Elapsed time should be 1.55 ±0.3 seconds.
