How It Works - Ducati Energia REGO 5 Manuel D'instruction

REGO also offers other useful functions, such as panelboard
temperature measurements for controlling an external cooling fan (in
the 7- or 12-step model), a series of protections and associated alarms
to safeguard the capacitor banks and guarantee efficient system
performance, the possibility of counting the number of switching
operations of a certain step to prevent possible downtimes due to
failures and thereby increase the system's reliability, and other functions
as well.
NOTE: The front panel of REGO features a series of keys for
accessing functions and programming; some functions are activated
by pressing a combination of 2 keys: in this manual, when mention
is made of a two-key combination (e.g. AUTO/MAN + L ), it means
that the user must press the first key and, without releasing it, then
press the second one. (In fact the combination AUTO/MAN + L
activates a different function from the combination L + AUTO/MAN.

4) HOW IT WORKS

The measured current from the mains C.T. is filtered and compared
with the required power factor and the insensitivity zone: if the conditions
set by the user thus require, the L (or M) LED will light up and all the
banks necessary in order to reach the set power factor will be switched
into service in as little time as possible (compatibly with the capacitor
discharge time T1).
The controller automatically adjusts to the direction of circulation of
the current drawn from the C.T.
