Summary

General Operation and Safety

Preliminary Checks

Inspect alternator for damage upon receipt and ensure it is in order before use.

Storage

Store alternator in a clean, dry, indoor location if not in immediate use to prevent damage.

Mechanical Coupling

Refer to assembly instructions; ensure brush centering on slip rings for generators.

Electric Connection

Ensure connected equipment matches generator data and properly earth the unit.

Installation

Install in a well-ventilated area, ensuring clear air intake and discharge for proper cooling.

Maintenance

Keep alternator clean, check for abnormal vibrations/noises, and ensure ventilation is clear.

Assembly Instructions

B3;B9 FORM (single-bearing)

Instructions for single-bearing assembly using B3/B9 mounting form.

SAE FORM (single-bearing)

Instructions for single-bearing assembly using SAE mounting form.

Trouble Shooting

Lack of no-load voltage

Generator fails to start, possibly due to demagnetization or AVR fault.

Very low no-load voltage

Low no-load voltage may indicate low motor speed or AVR issues.

Very high no-load voltage

High no-load voltage can be due to incorrect AVR connections or settings.

Very low load voltage

Low load voltage suggests motor slowing, overload, or AVR faults.

Very high load voltage

High load voltage often indicates a faulty AVR.

Unbalanced voltages (3 ph)

Unbalanced voltages in 3-phase systems can stem from winding faults or loads.

Unstable voltage

Unstable voltage may result from incorrect P2 trimmer setting or AVR issues.

Fuse burns out

Blown fuse can be caused by incorrect AVR connections or overvoltage.

Machine overheating

Overheating may occur due to blocked air vents or overload.

Noisy generator

Noisy operation can be due to worn bearings or poor coupling.
