"Monitor" alphanumeric display

9.5 Measurement system  

The "Monitor" system displays a number of input and output measurements at different points in the system.
– Mains 1

– phase-to-phase voltages,

– currents of the three phases,
– frequency;

– Mains 2

– phase-to-neutral voltage,
– phase-to-phase voltages,

– frequency;

– battery
– voltage,

– charge or discharge current,

– remaining battery time (calculated for each UPS);
– inverter output

– phase-to-neutral voltage,

– phase-to-phase voltages,
– currents of the three phases,

– frequency,

– active and apparent power,
– ratio peak current / rated current rms;

– total load

– phase-to-neutral voltage,
– phase-to-phase voltages,

– currents of the three phases,

– frequency,
– active and apparent power;

– option

– battery temperature.

Note:
Frequency converters without batteries are not concerned by the battery measurements. The displayed battery voltage 

corresponds to the DC voltage at the RC output.
