List of primary messages

LOAD PROTECTED

ON-LINE MODE

This is the normal display when there are no alarms or problems and the load is correctly supplied by the inverter, in on-line mode.

LOAD PROTECTED

PARALLEL ON-LINE MODE

This is the normal display when there are no alarms or problems and the load is correctly supplied by the inverter in a parallel UPS system, in on-line mode.

LOAD NOT PROTECTED

ON-LINE MODE

This display indicates that the load is not supplied by the inverter, or that there is no battery backup. The arrow indicates the presence of one or more problems specified in secondary messages.

The buzzer sounds continuously.

LOAD NOT PROTECTED

PARALLEL ON-LINE MODE

Situation identical to that in the previous screen, but for parallel UPS systems.

LOAD PROTECTED BATTERY DISCHARGING Remaining battery time (min) = XX % kW used = XXX

The load is supplied by the inverter, but the normal AC source is down or outside tolerances and power is supplied by the battery.

This message indicates the remaining battery time in minutes prior to inverter shutdown and the percent load. The battery time calculation takes into account:

◗the percentage of full rated load power currently being drawn;

◗the type of battery;

◗battery temperature;

◗battery age.

The buzzer sounds slowly and discontinuously.

LOAD PROTECTED, LOW-BATTERY SHUTDOWN WARNING,

Remaining battery time (min) = XX % kW used = XXX

This message replaces the preceding if the power outage persists and the warning level has been reached.

The user is warned that the battery is about to shut down.

The buzzer sounds rapidly and discontinuously.

LOAD PROTECTED

ECO MODE

This is the normal display when there are no problems: the load is supplied by the inverter or the bypass AC source, and battery backup is available.

LOAD NOT PROTECTED

ECO MODE

This display indicates that the load is supplied but has no battery backup. The arrow indicates the presence of one or more problems specified in secondary messages.

The buzzer sounds continuously.

LOAD FORCED TO INVERTER ECO MODE

The load has been transferred to the inverter following a specific request by the user.
