11) DISPLAY OF MEASUREMENTS
Normally the display shows the system cosϕ.
A minus sign indicates a capacitive power factor.
N.B.: In the event of a power cut, the controller will not be able to
calculate the cosϕ and will alternately display " C.O.S. " and "-.-.-.".
Press the DATA key to display the measurement readings: every time
you press, the next parameter will be displayed.
The parameters are displayed in the following sequence:
"COS" (system power factor)
"UFF" (effective measured line voltage)
"IL"
(line current measured at the primary winding of the CT)
"PA"
(equivalent active power absorbed by load, in kW)
"PL"
(equivalent reactive power absorbed by load, in kVAr)
"thd"
(crest factor normalized to 1: values less or greater than 1
if harmonic distortion is present)
°
"
C"
(temperature inside panelboard enclosure at the point
where the controller is installed; the value shown may be
considered reliable after about 1 hour of operation)
12) ADDITIONAL FUNCTIONS
12.1 MANUAL OPERATING MODE
Press the AUTO/MAN key for about two seconds until the
corresponding LED lights up: the controller is now ready to be
programmed in the manual mode.
