1 INTRODUCTION AND SAFETY TIPS

CIRCUTOR S.A. thanks you for choosing one of the regulators from the Computer MAX 6f V12dc series. These units have been built with state-of-the-art technologies, including a powerful processor that can calculate the optimum algorithms and achieve the best correction of the cos φ.

The units comply with the EN 61010 Electrical Safety Standard, in accordance with the Low Voltage Directive requirements (LVD 73/23/EC), as well as the EMC Directive (2004/108/EC) and are, therefore, certified for use with the CE mark.

The purpose of this user manual is to describe the operating principles of the regulators of the Computer MAX 6f V12dc series and to define the installation, start-up, and operation procedures.

Safety

The installation and maintenance of the unit must be performed by qualified and authorised staff, in compliance with the national and international Standards. Handling or use of the unit different from that specified by the manufacturer may compromise user safety.

The main switch must be disconnected before any maintenance is performed on the cos φ regulation units. After a disconnection, wait at least 5 minutes to make sure that all capacitors have been suitably discharged.

The following safety precautions must be taken into account during installation, maintenance or start-up operations on units regulated by a computer Max 6f V12dc:

 Make sure that the units have the corresponding earthing connections before they are connected.

A faulty earthing connection could lead to a faulty operation and represent the risk of electrical discharge to the user or person handling the unit.

 The necessary precautions will be taken during maintenance operations to prevent the risk of

electrocution and electric shock. Make sure that the unit has been disconnected and wait until the capacitors have been fully discharged before handling or operating the unit. We recommend the use of safety goggles and gloves.

 Resonance can be produced when the power factor compensation units are connected with no

loads. In this case, the voltage harmonics can be amplified, causing damage to the power factor compensation units and other units connected to the network.

 Follow the start-up and stop procedures described in the manual to prevent damage to the unit

and/or adjacent units.

 Always use original spare parts or components when adjusting or replacing components and

follow the corresponding procedures described in the instruction manual.

1.1 Checks to be carried out when the regulator is received

On receiving the regulator, check that:



 The unit has not been damaged during transport.

 

 The type supplied is the same as that requested. (See label on the rear, Fig. 1.1)

 

 Check the features shown on the unit's label, to make sure that they are valid for the type of grid



where the unit will be connected. (Voltage and power supply frequency, measurement range, etc.)



 Follow the instructions described in section 3, in relation to the rest of the installation and setup.

 

 Please contact the technical-commercial service of CIRCUTOR, S.A. if you detect any anomalies.

1.2 Start-up Screen

A start-up screen will be displayed when the computer MAX 6f V12dc is powered, showing the unit's version. This information must be included when reporting any fault or defect

1.3 Definitions

The following definitions may be useful to understand some of the sections in this manual

1.3.1 4-Quadrant Regulator.

The regulator is capable of performing the measurement and regulation functions when the active power is transferred from the mains to the loads (common case in a consumer installation) or when the load is transferred to the mains (in the case of installations with generators that not only allow the consumption of energy, but can also export or sell energy).

1.3.2 FCP System (FAST Computerized Program).

This system controls the connection sequence of the different stages, tending to minimise the number of operations and matching the usage times of the different stages to achieve the determined final power demand. The operations are carried out in such a way that, in the case of stages with an identical power, the stage that has been disconnected the longest is connected when there is demand and the stage that has been connected the longest is disconnected in the case of a surplus.

1.3.3 Stages and Steps

A distinction must be established between stages and steps. In this manual, a STAGE is described as the capacitor banks in which the power factor compensation unit is divided and that may have different power ratings, usually in 1:1, 1:2, 1:2:4, etc. ratios.

A step is each one of the total power fractions that can be regulated by using stages with different weights.

1.3.4 Regulation Program.

The power ratings of the different groups or stages usually follow certain patterns called "programs”. The program indicates the power ratios between different stages. The most frequent programs are:

Maximum no.

Computer Max 6f V12dc

Program 1:1:1 All stages have the same power rating. For example, a 100 kvar unit with 5 steps would be composed of 5 identical 20 kvar stages and would be described as a (5 x 20) kvar unit.

Program 1:2:2:. Starting with the second stage, each stage has twice as much power as the first stage. For example, a 180 kvar unit with 5 stages would be composed of a first 20 kvar stage and 4 identical 40 kvar stages, and so it could be described as a (20 + 4 x 40) kvar unit.

Program 1:2:4 The second stage has twice as much power as the first stage and the remaining stages after the second stage have four times as much power as the first stage. For example, a 300 kvar unit with 5 stages would be composed of a first 20 kvar stage, a second 40 kvar stage and 3 identical 80 kvar stages, and so it could be described as a (20 + 40 + 3 x 80) kvar unit.

Other Programs. Other programs can be used, such as 1:2:4:8 or 1:1:2:2, etc. The numbers, as can be deduced from the preceding cases, give the power ratio between the first stage, which receives a value of 1, and the subsequent stages (2 means twice as much power, 4 means four times as much power, etc.).

The unit comes equipped with a program called P00 that simulates and displays the number of steps that would be connected on the screen, without actually connecting them. It is used to see the unit's behaviour in safe mode.
