System information (continued)

41B: battery equalization (0=not active/1=active)

The rectifier-charger has been manually switched to equalization mode, to equalize battery cell voltages. This action stops all inverters powered by the battery (if they were not already stopped).

41E: operation on engine- generator set (0=not activated / 1=activated)

Indicates that the rectifier-charger is supplied by an engine-generator set and not by the normal Mains 1 power supply.

Word address: 44

440:inverter stack overload (0=no/1=overload)

Indicates an overload condition due to a load power factor exceeding 0.9.

441:major inverter fault (0=no/ 1=fault)

Informs the user of an inverter fault requiring after-sales servicing.

445:inverter output current limiting (0=no/1=active) Informs the user that an overload exceeding 1.6 In has occurred at the output: the inverter stops operating.

446:inverter thermal overload (0=no/1=overload)

Informs the user that the output is overloaded by a factor between 1 and 1.6 In: the inverter stops operating.

44C: outside contact (0=not activated/1=activated)

Normally open switch. Initiates the actions that have been configured using the after-sales "Soft Tunor" computer software. Possible actions when activated:

no action;

inverter off;

forced inverter shutdown;

conditional inverter shutdown;

frequency change (when powering on the unit) with respect to the frequency configured by the after-sales "Soft Tunor" computer software (i.e. 50Hz to 60Hz or vice versa).

44D: emergency off switch (0=not activated/1=activated) Normally-closed switch connected to the units. When activated, the rectifier-charger circuits and the inverters stop operating. The "QF1" battery circuit breaker is also opened. If the "emergency off" also trips the protection devices to disconnect the units from Mains 1 and Mains 2, the load no longer receives power and the units are completely disconnected.

Word address: 46

464:forced inverter shutdown (0=not activated / 1=activated) Indicates to the user that a shutdown of the inverter will result in transfer of the load to Mains 2 with the risk of a 0.8 second interruption in the supply of power to the load.

465:frequency conversion (0=not activated / 1=activated) Indicates that the

MGETM GalaxyTM 6000 UPS is operating as a frequency converter between the input and the output (50 Hz / 60 Hz).

466:conditional inverter shutdown (0=not activated / 1=activated)

Indicates to the user that a shutdown of the inverter will take place only if the load transfer conditions to Mains 2 are correct to avoid an interruption in the supply of power to the load.

Word address: 48

480:inverter overload (0=no/ 1=overload)

Informs the user that the load is drawing more than the rated UPS output.

482:ventilation of the battery cabinets (0=no fault / 1=fault) Indicates to the user that ventilation in a battery cabinet is incorrect due to a fan fault or shutdown. This fault does not result in UPS shutdown. This information is available only on European versions of the

MGETM GalaxyTM 6000 UPS.

484:inverter connected to the load (0=not connected/ 1=connected)

The inverter is operating and powers the load.

485:inverter off disable (0=enabled/1=disabled) The inverter off command is disabled.

486:synch with Mains 2 (0=not synch/1=synch)

The inverter may operate without its frequency synchronized to that of Mains 2 (i.e. free-running operation); in this case, it operates at an accurate (within 0.05 Hz) fixed frequency. Alternatively, the inverter may be operated with its frequency synchronized to that of Mains 2.

487:transfer fault (0=no fault/ 1=fault)

Informs the user of a fault on the static switch, used to transfer the load between Mains 2 and inverter output. After-sales servicing is required.

48A: Mains 2 voltage outside tolerances (0=normal / 1=outside tolerances)

Indicates to the user that the Mains 2 backup power supply voltage is outside tolerances. A transfer of the load to the Mains 2 backup power supply will result in a 0.8 second interruption in the supply of power to the load or may not take place.

48D: emergency off switch (0=not activated/1=activated)

Normally-closed switch connected to the units. When activated, the rectifier-charger circuits and the inverters stop operating. The "QF1" battery circuit breaker is also opened.

If the "emergency off" also tripped the protection devices to disconnect the units from Mains 1 and Mains 2, the load no longer receives power and the units are completely disconnected.
