1 SAFETY INFORMATION

To guarantee the safety of the operators, the correct installation and proper operation of the equipment, the following
precautions must be taken:

Installation and maintenance services should be performed only by qualified personnel, using appropriate equipment.;

The product instruction manual and specific product documentation must always be consulted before proceeding with its
installation, handling and parameter setting;

Adequate precautions should be taken to avoid drops, knocks, and/or risks to the operators and the equipment.
Always disconnect the main power supply and wait for the alternatorto come to a complete stop, before touching any
electrical component associated with the equipment including the control connectors. Do not touch the input and output
connectors since high voltages may be present even after the power has been switched off and keep them isolated from
the rest of the principal command circuit of the generator.

2 STORAGE AND TRANSPORT

If the alternatorneeds to be stored for a short period of time before its installation and/or start-up, the following measures
should be taken:

The regulator must remain in its original package or in a similar package which provides the same safety conditions
against mechanical damages, excessive temperature and humidity so as to avoid rusting of contacts and metallic parts,
damages to integrated circuits or any other damage arising from improper storage;

Properly packaged, the regulator must be kept in a dry and well-ventilated area away from direct sunlight, rain, wind and
other adverse weather conditions in order to ensure the preservation of its operational functions.

After the regulator is properly packed and secured in such a way as to absorb shock and vibrations during shipment, the
same will be ready for most means of transportation.
Failure to comply with the above mentioned recommendations could exempt the supplier of the equipment from any
responsibilities and liabilities from any resulting damages, as well as voiding the warranty on the equipment or damaged
part.

3 INTRODUCTION

The AVR-A-OPT-03 compact electronic Automatic Voltage Regulators are highly reliable and low cost products which
were developed using state of the art technology for voltage regulation of single-phase and three-phase brushless
synchronous generators.
The control and regulation circuit of this AVR uses semiconductors and integrated circuits tested within the highest quality
standards. It doesn't have mechanical components to start generating and the system is totally static and encapsulated
with epoxy resin, which makes it resistant to maritime environments, able to withstand vibrations of up to 50 mm/s. It has
internal voltage adjustment via trimpot and external voltage adjustment via potentiometer.
The control system is adjusted by one trimpot, which adjusts the stability, making possible a large adjustment range that
allows the operation with all kinds of generators and with several dynamic characteristics. It also has under-frequency
protection (U/F limiter). Its intervention point is adjustable via trimpot, and the nominal operation frequency can be
configured for 50 or 60 Hz.
