The communication parameters installed in the unit are:

Speed:

9600 bps,

parity:

No,

data bits:

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
