1.24 DESCRIPTION OF FUNCTIONS MENU PARAMETERS
P.41 - VT1 ratio
Specifies the ratio of any VT connected to terminals L1-L2. Refer to the list of wiring
diagrams.
P.42 - VT2 ratio
Specifies the ratio of any VT connected to terminals L1-L3. Used only with D and E type
connection. Refer to the list of wiring diagrams.
P.43 - Programmable input function
Defines the function of the input, terminals 18 and 19.
If set to OFF, the input is disabled.
−
If set to ntC, it is used as external temperature measurement via the specific probe
−
with ntC sensor. When set other than to ntC, temperature is detected via the sensor
inside the controller.
If set to 2.Co, closing a potential free contact connected to the terminals, a second
−
cosφ set-point placed in the parameter P.44 can be selected.
If set to noA or ncA, a potential free contact (normally open with NoA or normally
−
closed with ncA) can be connected for generation of the E.AL external alarm.
P.44 - Second cosφ set-point
Used to set the second cosφ set-point that can be selected using the programmable
input. See previous parameter.
P.45 - Minimum voltage threshold
Defines the tripping threshold for alarm A05 low voltage.
Note: For type D and E connections, this threshold is used in combination with the
phase-to-phase voltage applied to the capacitors.
P.46 - Maximum voltage threshold
Defines the tripping threshold for A06 alarm high voltage.
Note: For type D and E connections, this threshold is used in combination with the
phase-to-phase voltage applied to the capacitors.
P.47 - Measurement of harmonic events
Selects the measurement to be monitored for logging of harmonic events.
Possible selections: capacitor current overload, phase-to-phase voltage THD, current
THD.
P.48 - Harmonic event threshold
Defines the threshold to be applied to the measurement selected with the previous
parameter.
When the measurement exceeds this threshold, a harmonic event is generated, i.e. both
the waveforms (voltage-current) and the harmonic spectrum present at that moment are
saved.
