MEASURES VISUALISATION

The measures reading is visualised on the display 

E

, showing the three phase measures (L1, L2 y L3 respectively) of the 

indicated parameter by the 

C 

LED. For measuring the phase to phase voltage (V 

L-L

), the three measures are understood 

V 

L1-L2

, V 

L2-L3

, V 

L3-L1 respectively, as indicated on the front plate. 

The selection of the parameter to be visualised is made by pressing the key 

B

. It will be indicated by the 

C 

LED. 

By pressing the key 

A, 

the selected parameters will be visualised on display 

E

, as three phase values (average of the 

individual phases for voltages and currents) with the corresponding lighting of the LED, placed internally in the key. 
With 

LED 

Σ

L 

turned off and unbalanced three phase system mode (UNBALANC) are displayed in the following 

sequence: 
- 

LED VL-N 

ON:            On the display are showed the phase voltages 

- 

LED VL-L 

ON:            On the display are showed the phase to phase voltages 

- 

LED A 

ON:                  On the display are showed the phase current 

- 

LED Hz 

ON:              on  L3  display  is  showed  the  frequency  measured  on  L3  phase,  on  L1  display  will  appear  the 

message  PHASE  ROTATION  with a bright dash that rotate clockwise to indicate that the 
phase rotation is correct, or the message  ERR  if the phase rotation is wrong. 

- 

LED h 

ON:                  On  the  display  are  showed  the  phase  hour  counters  HR1,   HR2,   HR3.  The reading of the 

meters uses the 6 digits (maximum reading 99999.9) of the 

E 

display the measure comes 

visualised in such a way that, the display L1 will show the first 3 digits, the display L2 the second 
3 digits and the display L3 the identification of the corresponding hour meter (HR1,  HR2,  HR3). 
Each hour counter is activated when the measure of phase corresponding to the selected 
parameter  exceed  the  threshold  set  (see  SET    HR_).  The  measure  is  expressed  in  hour 
(integer) and tenths of hours (decimal). 

By pressing the 

A 

key the LED 

Σ

L is enabled and the system values are displayed. 

Please note that the unit value may be expressed in kilo, when the corresponding LED 

C 

are glowing (indicated in the 

front plate as 

k

). 

The visualised frequency is referred to the line L3.
