GENERATOR PRODUCES HIGH VOLTAGE
CAUSE
Faulty metering
Incorrect connections
Regulator adjustments
Leading power factor
Incorrect regulator connection
Defective regulator
GENERATOR BUILDS VOLTAGE FROM STARTUP,THEN GOES TO LOW (RESIDUAL) VOLTAGE
CAUSE
Regulator protective circuit operating
GENERATOR IS OVERHEATING
CAUSE
Generator is overloaded
Clogged ventilating screens
High room temperature or altitude
Insufficient circulation of cooling air
Unbalanced load
GENERATOR PRODUCES MECHANICAL NOISE
CAUSE
Defective bearing
Loose or misaligned coupling
CHECK AND REMEDY
Check voltage with separate meter at generator terminals.
Verify generator connections. Refer to drawings supplied with the generator or connection diagrams in this manual.
Adjust regulator. Consult regulator manual.
Check the power factor of the load. If power factor is leading, change load configuration. Excessive leading power factor (capacitors) can cause
voltage to climb out of control.
Verify regulator voltage sensing is connected correctly. Consult regulator manual.
Replace regulator.
CHECK AND REMEDY
Check indicators on regulator. Correct problems and adjust regulator as is required. Refer to regulator manual.
CHECK AND REMEDY
Reduce load. Check with ammeter and compare with nameplate rating.
Clean air passages.
Improve ventilation or reduce load.
Generator location and enclosure design must provide adequate air flow and minimize recirculation of hot air.
The load on each leg should be as evenly balanced as possible and should not exceedrated current on any one leg.
CHECK AND REMEDY
Replace bearing.
Tighten, realign, or replace coupling.
