value of the flashing digit.

When the on-screen value is that desired, press the

min

key to go to the next digit to

modify the other values.

If you press the

min

key after changing the last digit, it will jump back to the first digit so

you can modify the previously programmed values again.

To validate the information and go to the next programming step, press

Note: The analyzer does not record programming changes until the programming is complete;

if it is reset before the programming is completed, the configuration will not be stored in the

memory.

Note: For more basic information see the quick installation guide for the CVM-MINI-RS485

which is included with the documentation you received with the unit, and for full information see

the complete unit manual on the web site: www.circutor.com.

7.- Once you have finished programming the CVM-MINI-RS485, check the readings on the

display: phase-phase voltage and phase-neutral voltage values for each phase, current of each

phase, active power of each phase, reactive power of each phase and power factor (

cos φ) of

each phase.

It is important to confirm that the values on the display are logical in terms of the features of the

network being compensated.

It is essential to ensure the correct correlation between the voltage and current measurement

signals (phase concordance) and that there are no negative active power values, which would

indicate that there is a current transformer with inverted polarity or an incorrect phase sequence

between voltages and currents.

For example: if the current signal for phase 1 does not corre-

spond with the voltage phase 1, and instead corresponds with another phase.

If these incorrect values are shown on the display, recheck the position of the current transform-

ers and check for any connection errors that may have occurred.

As a guideline, remember that in a standard installation with a normal load level, the

cos φ

measured by each phase should range between

0.5 and 0.95 inductive.

shows the correct connection of the current transformers with respect to the connec-

tion of the

OPTIM HYB capacitor bank to the network.
