At this point, the controller no longer requires any type of setting and
will be ready for perfect operation: it will alternately display "COS" and
the system power factor.

9) TESTING CONTROLLER PERFORMANCE
To immediately check whether the controller is working efficiently,
the user should keep in mind that:
– When the load is started, the controller should turn on the L LED
and switch the capacitor steps into service.
– If the load is reduced or removed, the controller should turn on the
M LED and disconnect capacitor steps accordingly.
– When the L and M LEDs are off, the controller should display a
cosϕ close to the one set (see chap.10.2 - Page 66).
– As the inductive cosϕ increases up to 1, the current circulating
upstream from the power factor correction decreases, whereas it
increases with the capacitive cosϕ.
10) SETUP PARAMETERS
N.B.:If the controller is installed on a DUCATI ENERGIA automatic
power factor correction system we advise the user not to change
any setup parameters with the exception of COS and IL.
To enter the setup menu press L + M. The display will show the
following parameters:
