Step 2. Check for generator overloading.
If the generator is operating with a larger than rated load, shed load.
If the generator is operating with a rated or less than rated load, proceed to Step 3.
Step 3. Replace the BE2000E.
If replacing the BE2000E does not correct the malfunction, proceed to Step 4.
Step 4. Refer to the generator manual. Generator is defective.
LOSS OF GENERATOR SENSING Indicator Is Annunciating
Step 1. Verify that the voltage sensing leads are properly connected.
If the sensing leads are not properly connected, correct the connections.
If the sensing lead connections are correct, proceed to Step 2.
Step 2. For single-phase sensing, verify that E2 and E3 are connected.
If E2 and E3 are not connected, connect them both to phase C sensing voltage.
If E2 and E3 are properly connected, proceed to Step 3.
Step 3. Verify that the sensing potential transformer (if used) has the correct turns ratio and is
functioning properly.
If the sensing potential transformer has the wrong turns ratio or is malfunctioning, replace it.
If the sensing potential transformer is correct and functioning properly, proceed to Step 4.
Step 4. Verify that the generator output voltage is present on all phases.
If the generator is missing a phase, refer to the generator manual. Generator is defective.
If generator output voltage is balanced on all phases, proceed to Step 5.
Step 5. Replace the BE2000E.
OVEREXCITATION LIMITING Indicator Is Annunciating
Step 1. Check for generator overloading.
If the generator is operating with a larger than rated load, shed load.
If the generator is operating with a rated or less than rated load, proceed to Step 2.
Step 2. Verify that the BE2000E output (field) current limit is not set too low.
If the output current limit setpoint is too low, adjust for the proper setting.
If the output current limit is set properly, proceed to Step 3.
Step 3. Verify that the generator exciter field is not shorted.
If the generator exciter field is shorted, replace the generator.
If the generator exciter field is not shorted, proceed to Step 4.
Step 4. Replace the BE2000E.
If replacing the BE2000E does not correct the malfunction, proceed to Step 5.
Step 5. Refer to the generator manual. Generator is defective.
UNDERFREQUENCY ACTIVE Indicator Is Annunciating
Step 1. Verify that the generator is operating at rated speed.
If the generator is not operating at rated speed, adjust the generator speed.
If the generator is operating at the rated speed, proceed to Step 2.
