CIRCUTOR OPTIM HYB Series - Manual (Page 10)

 The available combinations for standard models are selected through internal mini-dips.
The programming is done in-factory and should not be modified, except by
CIRCUTOR personnel or by those properly trained in its use.
Note: If you need to find out the configuration 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.

 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 mm 2 .
