OPTIM HYB Series

1.- VERIFICATION UPON RECEPTION

1.1.- RECEPTION PROTOCOL

Check the following points when you receive the unit:

a) The unit meets the specications described in your order.

b) The unit has not suffered any damage during transport.

c) Perform an external visual inspection of the unit prior to switching it on.

d) Check that it has been delivered with the following:

- The unit manual.

- The CVM-MINI-RS485 quick installation guide.

If any problem is noticed upon reception, immediately contact the transport

company and/or CIRCUTOR's after-sales service.

1.2.- TRANSPORT AND HANDLING

The transport, loading and unloading and handling of the unit must be carried

out with proper precautions and using the proper manual and mechanical

tools so as not to damage it.

If the unit is not to be immediately installed, it must be stored at a location

with a rm and level oor, and the storage conditions listed in the technical

features section must be observed. In this case, it is recommended that the

unit be stored with its original protective packaging.

To move the unit a short distance, the unit's oor support proles facilitate handling with a pallet

jack or forklift. (Figure 1)

Figure 1: Transport with pallet jack.

The centre of gravity of some units may be found at a considerable height.

Therefore, when handling with a forklift, it is recommended that the unit be

securely fastened and that no abrupt manoeuvres made. The unit should not

be lifted more than 20 cm off the ground

OPTIM HYB Series

Instruction Manual

When unloading and moving the unit, use a forklift with forks long enough to support the entire

length of the base. Otherwise, the forks should be long enough to support at least ¾ of said

depth. The forks must be at and supported rmly by the base. Raise the cabinet by placing the

forks underneath the prole that supports the unit. (Figure 2).

There might be an offset in the centre of gravity from the centre of the cabinet,

as a result of the uneven distribution of loads inside the unit. The necessary

precautions must be taken to prevent the unit from tipping over during abrupt

operations.

Figure 2: Unloading with a forklift.

1.3.- STORAGE

The following storage recommendations must be followed for the hybrid capacitor banks:

 Avoid placing them on uneven surfaces.

  Do not store them in outdoor areas, humid areas or areas exposed to splashing

water.

 Avoid hot spots (maximum ambient temperature: 40 ºC)

 Avoid salty and corrosive environments.

  Avoid storing the units in areas where a lot of dust is generated or where the risk of

chemical or other types of contamination is present.

 Do not place any weight on top of the unit cabinets.

2.- PRODUCT DESCRIPTION

The purpose of this manual is to assist during the installation, start-up and maintenance of

OPTIM HYB series low voltage (LV) capacitor banks with static operation. Carefully read the

manual to achieve the best performance from those units.

2.1.- CAPACITOR BANK COMPONENTS

From the electrical standpoint, the unit is made up of the following blocks:

2.1.1. HYBRID REGULATOR

The hybrid capacitor banks are equipped with Computer HYB hybrid regulators (Figure 3).

Figure 3: Computer HYB Hybrid Regulator.

This regulator has two types of outputs (see the inputs and outputs identied in Figure 4.:

6 relay outputs with operating voltage of 250 V ~. and operating current of 4 A (AC1) for

the auxiliary control voltage of the electromechanical contactors that operate the three-phase

capacitors (three-phase steps of the OPTIM HYB capacitor bank).

 24 static outputs to provide a 12 Vdc activation signal to the + and - inputs of the CPC2

connection controller boards at zero voltage difference. These boards control the semiconduc-

tor modules (thyristor-diode) and operate the single-phase capacitors (single-phase steps of

the OPTIM HYB capacitor bank).

The Computer HYB also has the following notable features:

 The necessary information to calculate compensation demand by phase is provided by a

CVM-MINI-RS485-model power analyzer via RS-485 communications with the Modbus/RTU

protocol.

OPTIM HYB Series

Instruction Manual

The communication parameters installed in the unit are:

Speed: 9600 bps, parity: No, data bits: 8, stop bits : 1

The standard OPTIM HYB models come with the CVM-MINI-RS485 analyzer built into the door

panel and programmed with the above values.

Note: If the OPTIM HYB capacitor bank does not include the CVM-MINI-RS485 analyzer and

you intend to use the existing unit in the installation to be compensated, with an RS-485 output

that is not being used to communicate with any data display system, the RS-485 communica-

tions must be programmed as indicated above.

(For more information, see the CVM-MINI-RS485 instruction manual at www.circutor.com).

The connection terminals for the external RS-485 signal are indicated in Figure 4.

 Unit auxiliary power supply: 230 V ~ ± 10 % / 50-60 Hz.

 Setpoint value of target cos phi set at 1, individually for each phase.

 Regulation with a delay between connections/disconnections (response to compensation de-

mands) differentiated between the single-phase steps operated by semiconductors by default

of 1 s; and the three-phase steps by default of 20 s.

 Reactive power compensation algorithm consisting of prioritising the connection of sin-

gle-phase steps to compensate more quickly, and of substituting these connected single-phase

steps for a three-phase step when the compensation needs allow it.

Thus, the connected single-phase steps are replaced with a three-phase power step with an

equivalent phase if 20 s after the last single-phase stage is connected there is an available

three-phase step in the capacitor bank with the same three-phase value for the 3 connected

single-phase stages. In this situation, the single-phase steps would be disconnected and the

three-phase equivalent would be connected at the same time. In this way, the single-phase

stages are again enabled for fast connection if new three-phase or single-phase compensation

demands arise.

 LEDs on the front panel indicating the connected stages, CPU operation, communication

status with the CVM-MINI-RS485 and alarm signals. See Figure 5 for a detailed description of

the LEDs on the Computer HYB front panel.

Additional input for RS-485 communications, for programming and control of internal regula-

tor functions

Note: only for use by CIRCUTOR personnel or by those properly trained in its use.

Instruction Manual

OPTIM HYB Series

 The available combinations for standard models are selected through internal mini-dips.

The programming is done in-factory and should not be modied, except by

CIRCUTOR personnel or by those properly trained in its use.

Note: If you need to nd out the conguration of the mini-dips for each combination, please

contact CIRCUTOR technical assistance.

The available staging combinations as of the date of publication of this manual are exclusively

those indicated in Table 2:

Table 2:Available stage combinations.

OPTIM HYB3-540-440 (3 x 3 x 10) kvar / 230 V + (6 x 60) kvar / 400 V / 50 Hz

Digital input for external temperature relay signal (Figure 4) installed at the top of the heatsink

to dissipate the semiconductors. ( Normally in closed position )

In the event of an alarm, the connected steps would disconnect until the thermal relay returns

to its NC position and the condition triggering the alarm disappears.

The alarm situation is indicated by a combination of lit LEDs on the front panel of the Computer

HYB (See Figure 5).

 Lack of compensation alarm, installed in the Computer HYB.

The alarm goes off when the non-compensated three-phase power is greater than 30% of the

total three-phase power available in the capacitor bank, or in other words, is greater than 30%

of its nominal power of 400 V~.

The alarm situation is indicated by the cos φ LED being lit on the front panel of the Computer

HYB. (See Figure 5).

2.1.1.1. Computer HYB Regulator Connections.

Note : See the general connection diagram in “7.- OPTIM HYP TYPE DIAGRAM”

The regulator comes fully connected, expect in the case of units that do not have the CVM-MI-

NI-RS485 analyzer.

In this case, you must connect the CVM-MINI-RS485 communications output to the ASB COM2

terminal of the Computer HYB, using a shielded communication cable with at least 3 wires and

with a section of at least 0.25 mm2.
