5.- Connect the power supply of the OPTIM HYB capacitor bank, closing the general quadru-
pole switch inside the capacitor bank using its lever (ON position) and check that the CPU LED
and the RS485 COM 2 RX and TX LEDs light up immediately and flash at an approximate rate
of once per second.
This indicates the correct operation of the Computer HYB processor and correct communica-
tions between the Computer HYB and the CVM-MINI-RS485, respectively.
6.- Check that the CVM-MINI-RS485 (in the OPTIM HYB models that come equipped with it)
installed in the door of the capacitor bank lights up, and then program the primary value of the
current transformers that provide the measurement signal to the analyzer. Follow the steps
below for this programming:
A.- Access the MEASUREMENT Setup by pressing the SETUP key until the unit enters
into programming mode.
The screen shown in Figure 15 will appear on the display, which allows you to program
the voltage primary.
Note : This programming is not necessary for 3 x 400 V / 1 x 230 V networks.
