INVERTER FAULT

CALL SUPPORT DEPT.!

A fault has occurred in the inverter module requiring servicing by the after- sales support department.

INVERTER SHUTDOWN

OVERLOAD > IMAX

!

An overload greater than 1.6 In has occurred on the load, resulting in inverter shutdown.

INVERTER SHUTDOWN

OVERLOAD > IN

A

An overload between In and 1.6 In has occurred on the load, resulting in inverter shutdown. The blinking "A" at the end of the message is a prompt to read the load current measurement.

AUXILIARY CONTROL

SIGNAL RECEIVED !

An auxiliary "Media Contacts 15" option signal has been received. The next display will indicate which of the four possible functions was set.

FORCED UPS SHUTDOWN

AUXILIARY CONTROL

The UPS has received a forced shutdown command. This corresponds to an auxiliary control signal received via a "Media Contacts 15" option set for this function.

PROTECT.UPS SHUTDOWN

AUXILIARY CONTROL

The UPS has received a shutdown command. This command will only be executed if load transfer conditions on Mains 2 are satisfied. This corresponds to an auxiliary signal received via a "Media Contacts 15" option set for this function.

FREQUENCY REVERSAL AUXILIARY CONTROL

The UPS has received a command to change its output frequency (50 or 60Hz).

This command is only executed if the inverter is off. The frequency will be changed the next time the inverter is started. The command corresponds to an auxiliary control signal received via a "Media Contacts 15" option set for this function

.

I LOAD > IN

CHECK LOAD

A

The power drawn by the load is greater than the rated value. The blinking "A" at the end of the message is a prompt to read the load current measurement.

TRANSFER FAULT

CALL SUPPORT DEPT.!

A fault has occurred in the static switch which ensures transfer of the load between the inverter and Mains 2. Servicing by the after-sales support department is required.

PHASE OUT OF LIMITS

!

For a single-unit UPS or Static Switch Cubicle, the phase shift between the inverter and Mains 2 is outside tolerances. Transfer of the load between the inverter and Mains 2 will result in an interruption in the supply of power to the load.

For a parallel UPS, the phase shift between this inverter and the other inverters is outside tolerances, and the corresponding UPSs has therefore been disconnected.

MAINS 2 SWITCH

Q4S OPEN

!

Mains 2 input switch Q4S is open, i.e. transfer of the load from the inverter is impossible.

OUTPUT SWITCH

Q5N OPEN

!

MAINT. BYPASS SWITCH

Q3BP CLOSED

!

Maintenance bypass switch Q3BP is closed. The system is in maintenance configuration and the load is supplied by Mains 2.

EMERGENCY OFF

OVERLOAD > IN

!

The load is no longer supplied by Mains 2 following an extended overload.

BATTERY

CHARGING!

The battery is currently being recharged.

INDEPENDENT

INVERTER FREQUENCY!

The inverter frequency is stable and accurate to 0.05Hz, but no longer synchronous with that of Mains 2.

NUMBER OF INVERTERS

READY INSUFFICIENT!

This message is valid only for parallel UPS systems. The number of UPSs ready for connection to the load is insufficient for the required power level. Another UPS must be started before all the lines together may supply the load. Until another line is started, the load will remain supplied by Mains 2.

BATTERY MAINTENANCE

CALL AFTER-SALES

Indicates that the battery has probably reached the end of its service life (based on the estimated average service life since its installation).

TRANSFER DISABLED

AUXILIARY CONTROL

Transfer of the load to Mains 2 is inhibited due to:

◗

certain transfer conditions not

satisfied;

◗

"transfer to Mains 2 with interruption

Inverter output switch Q5N is open, i.e. the load cannot be supplied by the inverter.

disabled" auxiliary contact of the

"Media Contacts 15" option closed.
