Important Notice
Our experience has shown that, if the information and recommendations contained in this Operating Instructions
are observed, the best possible reliability of our products is assured.
The data contained herein purports solely to describe the product and is not a warranty of performance or
characteristics. It is with the best interests of our customers in mind that we constantly strive to improve our
products and keep them abreast of advances in technology. This may, however, lead to discrepancies between a
product and its "Technical Description" or " Operating Instructions".
This document has been carefully prepared and reviewed, however should in spite of this the reader find an error,
he is requested to inform us at his earliest convenience.
It is scarcely possible for the operating instructions for technical equipment to cover every eventuality, which can
occur in practice. We would therefore request you to notify us or our agent in the case of all unusual behaviour that
does not appear to be covered by these operating instructions.
It is pointed out that all local regulations must be observed when connecting and commissioning this equipment in
addition to these operating instructions.
We cannot accept any responsibility for damage incurred as a result of mishandling the equipment regardless of
whether particular reference is made in these operating instructions or not.
We lay particular stress on the fact that only genuine spare parts should be used for replacements.
All rights with respect to this document, including applications for patent and registration of other industrial property
rights, are reserved. Unauthorized use, in particular reproduction or making available to third parties, is prohibited.

reference.
Required Qualification
Personnel involved in installation work and commissioning of the S2006 must be familiar, specially
instructed and informed about the residual danger areas according to the regulations currently in force.
Operating personnel is not permitted to work at the control system.
Specially instructed personnel must only carry out maintenance and repair work.
The maintenance personnel must be informed about the emergency shutdown measures and must be
capable of turning off the system in case of emergency.
The maintenance personnel must be familiar with the accident prevention measures at their workplace
and must be instructed in first aid and fire fighting.
It is the owner’s responsibility to ensure that each person involved in the installation and commissioning
of the S2006 has received the appropriate training or instructions and has thoroughly read and clearly
understood the safety instructions in this chapter.

6/67
1.2 Safety Instructions
The safety instructions always appear at the beginning of each chapter and/or precede any instruction in the
context where a potentially dangerous situation may appear. The safety instructions are divided into five categories
and emphasized by the use of the following layout and safety signs:
DANGER!
This symbol indicates an imminent danger resulting from mechanical forces or
high voltage. A non-observance leads to life-threatening physical injury or death.
WARNING!
This symbol indicates a dangerous situation. A non-observance may lead to bad
or life-threatening physical injury or death.
IMPORTANT!
This symbol indicates useful information. Not to be used to indicate dangerous
situations.
NOTICE!
This symbol emphasizes important information. A non-observance may cause
damage to the converter or to objects close to it.

2. PRODUCT DESCRIPTION
2.1 Preface
From a consolidated operating experience in the energy sector Beltrame has created a device of high performance:
the S2006 voltage regulator.
S2006 is an automatic voltage regulator of the latest design for synchronous generators and synchronous motors.
The unit contains the most advanced microprocessor technology together with IGBT semiconductor technology
(Insulated Gate Bipolar Transistor).
A practical and simple-to-operate panel on the unit is used for all control operations. In addition, user friendly
software facilitates commissioning and allows optimization of operation.
The mechanical construction is compact and robust. You can order the regulator in the rack configuration 19 ".

8/67
2.2 Area of application
This advanced-design automatic voltage regulator is used for the excitation of indirectly excited synchronous
machines. This unit is only suitable for this one area of application.
The regulator can also be switched over to function as a reactive power-, power factor- or field current regulator.
SM = Synchronous Machine
E = Exciter
PMG = Permanent-Magnet-Generator
Optional:
Synchronization unit
Diode monitoring
Change over to a back-up unit.
Generator or motor excitation with
PMG or external supply.
Replacement of voltage regulators for
generators or motors with direct-current
excitation machines.

2.3 Hardware
Structure:
The device is built into an aluminum casing with cooling flanges.
The connection terminals are integrated around of the circuit boards.
Power electronics:
The power part is fitted with an IGBT semiconductor.
The average value of the output voltage is always positive.
The output is current limited and short-circuit proof.
Control elements:
The operating keys and the display are located on the unit cover.
Installation:
The site of installation must be dry and free of dust.
Mounting:
The S2006 is designed for wall mounting.
For optimal cooling is to keep free a minimum distance of 100mm all around the unit.

3. OPERATOR INTERFACE
In this following charter are described the operations of management parameter, using programming keyboard.
3.1 Control keyboard and signaling
The modifications operated on the values of the parameters, also entering in action immediately, are not stored in
way automatic, but require a specific action of storage that is obtained by means of the command “C.000” [Save
parameters].
MScroll menu: Consent change menu’ parameter (d.xxx, R.xxx, I.xxx, P.xxx and C.xxx).
EEnter: used to begin setting parameter and/or confirm value;
UP: used to increase displaying parameter and/or numerical value;
DOWN: used to decrease displaying parameter and/or numerical value;
+ UP + DOWN = RESET
pushed both execute manual reset
K1 K1: the function is freely programmable by parameter
K2 K2: the function is freely programmable by parameter
Meaning of LED :
Run (green Led): - led on = The RUN command is enabled and activated
- led fast blinking = The controller is limiting
Ind (green Led): positive reactive power generated
Cap (green Led): negative reactive power generated

19/67
SW (red Led): - led on = Parallel Switch Closed
- led slow blinking = Operation outside the synchronization window
- led fast blinking = Operation within the synchronization window
Prg (yellow Led): - led on = when not ready to run
- led blinking = when a parameter modification is not saved
L1 (yellow Led): the function is freely programmable by parameter (default = calibrator at minimum)
L2 (yellow Led): the function is freely programmable by parameter (default = calibrator at maximum)
3.2 Navigating the menus
When the S2006 is power on, the display automatically shows parameter d.000 (Field current) in the Display menu.
