Step 4. Replace the BE2000E unit.
Poor Voltage Regulation
Step 1. Verify that the case of the BE2000E is properly grounded.
If the BE2000E is not properly grounded, connect a dedicated ground wire to the quarter-inch
fast-on connector labeled GND on the rear of the BE2000E case.
If the BE2000E is properly grounded, proceed to Step 2.
Step 2. Check for grounded field leads.
If the field leads are grounded, isolate them from ground.
If the field leads are not grounded, proceed to Step 3.
Step 3. Check for grounded PMG leads.
If the PMG leads are grounded, isolate them from ground.
If the PMG leads are not grounded, proceed to Step 4.
Step 4. Verify that the generator frequency is not dropping below the BE2000E underfrequency setpoint
when load is applied to the generator.
If the generator frequency is dropping below the underfrequency setpoint, reduce the setpoint if
possible. Also check the prime mover and generator for proper sizing in relation to the applied
load.
If poor regulation is not related to BE2000E underfrequency operation, proceed to Step 5.
Step 5. Verify that regulation is not being affected by normal droop operation.
If droop operation is not affecting regulation, proceed to Step 6.
Step 6. Replace the BE2000E unit.
Generator Output Unstable (Hunting)
Step 1. Verify that the governor for the prime mover is operating properly.
If the governor is not operating properly, troubleshoot using the manufacturer's suggested
procedures.
If the governor is operating properly, proceed to Step 2.
Step 2. Verify that the sensing and input power leads are connected securely.
If the sensing or input power leads are not connected securely, tighten the connections.
If the sensing or input power lead connections are secure, proceed to Step 3.
Step 3. Verify that the BE2000E Stability Range is set to the proper range.
If the Stability Range setting is incorrect, reset the Stability Range.
If the Stability Range setting is correct, proceed to Step 4.
Step 4. Verify that the Stability Level is properly set.
If the Stability Level is not properly set, reset the Stability Level.
OVEREXCITATION SHUTDOWN Indicator Is Annunciating
Step 1. Verify that the field overvoltage setpoint is adjusted properly.
If not properly adjusted, readjust the field overvoltage setpoint.
If properly adjusted, proceed to Step 2.
