"Monitor" alphanumeric display (cont.)

UPS IMPOSED

TRANSFER DISABLE !

Cannot transfer the load to Main 2 due to:

transfer conditions not satisfied;

UPS operating on an independent frequency;

UPS operating with current limitation;

internal fault;

auxiliary control inhibits switching to Mains 2.

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.
