MarelliMotori MARK VX Manual Del Usuario página 12

1. INTRODUCTION
This User Manual provides general installation and use information regarding the Marelli Motori regulator whose
code is reported on the cover and inside the document, mounted on Marelli Motori generator types indicated in
Chap. 3.
Before starting the generator and performing any type of regulation operation, carefully and completely read all of
the instructions contained in this manual.
IMPORTANT NOTE: This User Manual not intended to cover all of the possible application or installation variations
nor to provide data or information to support every possible contingency. The connection diagrams provided with
the generator, its Use and Maintenance Manual and any additional information provided by qualified Marelli Motori
technical personnel supplements and completes this manual.
In particular, the diagrams reported in this document provide only an example of the connection and operation
mode for the device; these do not cover all possible application cases and are not a substitute for the connection
diagrams normally provided with the generator.
If further application information becomes necessary, please contact Marelli Motori Service.
2. SAFETY PRECAUTIONS
ATTENTION: DO NOT TOUCH THE CONTROL MODULE WHEN IT IS UNDER POWER.
When the control module is under power (or the machine is in rotation) the upper part of the
device (connection side) and all parts electrically connected to it contain lethal voltage. There
could be also components with high temperatures that are dangerous in the event of direct contact
during normal operation on the component module.
Any operation on the cabling and/or mechanical installation of the regulator must be performed
by qualified and informed personnel, with the generator halted and making sure that a
sufficient amount of time has passed for the regulator components to have cooled down to a
temperature that is not dangerous to personal safety.
Marelli Motori denies any responsibility for damage to the regulator, system or people, for loss of profit or money, or
for system shutdowns caused by the failure to observe the safety and/or installation/use instructions reported in this
User Manual.
3. APPLICATION
The voltage regulator type M00FA122A - MARK VX is suitable for Synchronous Generators of Marelli Motori make,
MXB series. The regulator is proper both for single and 3-phase generators.
NOTE: For information on compatibility with different sizes or series of synchronous generators other than those
indicated above, contact Marelli Motori Service.
4. TECHNICAL SPECIFICATIONS
The M00FA122A voltage regulator can be calibrated using potentiometers. The circuit board is resin-bonded in
order to maintain a high degree of operational reliability even in difficult environmental conditions (high levels of
humidity, dust, a salty atmosphere) and in the presence of vibrations.
