Description
JCB SK160 Generator Use and Maintenance Manual covering the Sincro SK160 generator unit. This 80-page factory publication provides safety, installation, operation, adjustment and maintenance information for qualified electrical and mechanical personnel.
The manual is particularly useful when installing the generator onto an engine, carrying out commissioning checks, setting the automatic voltage regulator or investigating electrical and mechanical faults. It also identifies the unit’s data plates, serial number and production-order references required for correct identification.
This is a multilingual publication containing Italian, English, German, French and Spanish sections. The documented edition is October 2005, Revision 01.
GENERATOR OPERATION AND REGULATION
The manual explains the generator’s operating principle and the function of its excitation and voltage-regulation arrangements. Subjects include:
- Main and exciter stator operation
- Exciter rotor and rotating diode bridge
- Main rotor excitation
- Automatic voltage regulator operation
- Voltage control and regulation
- Frequency-control function
- Low-speed protection
- Regulator response and stability
- Regulator fuse protection
MECHANICAL AND ELECTRICAL INSTALLATION
Installation guidance covers handling the generator, coupling it to the driving engine and completing the necessary mechanical and electrical connections.
- Safe lifting and handling
- Generator identification and data plates
- SAE-form engine mounting
- SAE-form dismantling
- Rotor and flywheel coupling
- Engine-to-generator alignment
- Anti-vibration mounting arrangements
- Terminal-box connections
- Line, neutral and earth terminals
- Generator-frame earthing
