BYPASS SWITCH Q3BP

IS CLOSED

Maintenance bypass switch Q3BP is closed. The system is in maintenance configuration and the load is supplied by the bypass AC source.

STATIC SWITCH (M2) OFF

DUE TO AN OVERLOAD

The load is no longer supplied by the bypass AC source (M2), due to an extend- ed overload. The buzzer sounds continu- ously.

BATTERY CHARGING

I BAT. = XXX A U BAT. = XXX V

The battery is currently being recharged.

BATTERY AT END OF SERVICE LIFE CALL MAINTENANCE

The battery is nearing the end of its esti- mated service life. This information is based on average service-life calculations since its initial installation. The buzzer sounds slowly and discontinuously.

EMERGENCY OFF

This message is displayed when the external emergency-off pushbutton is pressed. The result is:

■shutdown of the inverter;

■shutdown of the rectifier/charger;

■opening of the battery circuit breaker;

■blocking of the static bypass;

■opening of the backfeed protection con- tactor (M2),

■opening of the Q1 circuit breaker (M1),

■activation of a relay contact on the remote-indications relay board. Servicing by the after-sales support department is required.

The buzzer sounds discontinuously.

THE BATTERY C.B. QF1 IS OPEN, CHECK THE INSTALLATION

Battery circuit breaker QF1 is open. The load is no longer protected because bat- tery power is no longer available in the event of a normal AC source outage. The buzzer sounds continuously.

LOW BATTERY SHUTDOWN

The inverter has shut down at the end of battery power. The buzzer sounds continu- ously.

INTERNAL UPS FAULT,

INVERTER FAULT,

CALL MAINTENANCE

A fault has occurred in the inverter. Servicing by the after-sales support department is required. The buzzer sounds continuously.

INTERNAL UPS FAULT,

CHARGER FAULT,

CALL MAINTENANCE

A fault has occurred in the rectifier/charg- er. Servicing by the after-sales support department is required.

The buzzer sounds slowly and discontinu- ously.

FORCED TRANSFER TO INVERTER REQUESTED, POWER TO LOAD MAY BE INTERRUPTED, CONFIRM YOUR REQUEST WITH KEY ↵

The requested transfer to the inverter may provoke an interruption in the supply of power to the load if Mains 2 characteris- tics are not within the specified tolerances.

THE NUMBER OF UPS READY IS INSUFFICIENT,

LOAD TRANSFER IN STAND BY

This message may be displayed in non- redundant, parallel UPS systems, when the number of ready inverters in not suffi- cient to supply the load.

INVERTER NOT CONNECTED

This message may be displayed in parallel UPS systems, when the inverter is not connected to the load.

PARALLEL UPS,

FORCED TRANSFER INHIBITED

This message is displayed when forced connection is requested on a parallel UPS system for a power extension.

INTERNAL UPS FAULT,

SELF-TEST FAULT

Communication between the system and the display is faulty. The buzzer sounds slowly and discontinuously.

FORCED TRANSFER TO M2 REQUESTED,

POWER TO LOAD MAY BE INTER- RUPTED

CONFIRM YOUR REQUEST WITH KEY ↵

This message is displayed following pressing of the "forced-transfer" key 20, when the load is supplied via the inverter.

UPS SUPPLIED BY A GENERATOR SET

This message informs the user that the UPS has received the order to limit the current drawn by the rectifier/charger. It is displayed when the corresponding signal is transmitted by the remote indications board which must be configured for this function.

VENTILATION FAULT

This message is displayed when a fault occurs on a fan.
