LOAD ON MAINS 2

The load has been transferred to the bypass AC source (M2) and is no longer protected (only in on-line mode). The buzzer sounds continuously.

MAINS 2 OUTSIDE TOLERANCES TRANSFER DISABLED

CHECK MAINS 2

The bypass AC source (M2) frequency or voltage is outside tolerances and the inverter is unable to synchronize. Transfer of the load from the inverter to the bypass AC source (M2) or vice-versa will result in an interruption of the supply of power to the load. The buzzer sounds slowly and discontinuously.

BATTERY OVERTEMPERATURE, CHECK VENTILATION

The battery temperature is outside toler- ances. The buzzer sounds slowly and dis- continuously.

BATTERY ROOM VENTILATION FAULT, CHECK VENTILATION

A fault requiring servicing has occurred in the battery room ventilation system. The rectifier/charger shuts down after a 30- second time delay.

The user must take steps to re-establish correct operation of the ventilation system. This message also signals an abnormally high temperature in the filter inductor.

The buzzer sounds slowly and discontinu- ously.

MAINS 1 OUTSIDE TOLERANCES, CHECK MAINS 1

The normal AC source (M1) frequency or voltage is outside specified tolerances and the rectifier/charger has shut down. The inverter is on battery power.

MAINS 1 INPUT SWITCH Q1

IS OPEN

The normal AC input (M1) switch Q1 is open. It must be closed for rectifier/charg- er start-up. The buzzer sounds slowly and discontinuously.

INTERNAL UPS FAULT,

LOAD TRANSFER FAULT,

CALL MAINTENANCE

A fault has occurred in the static switch that transfers the load between the invert- er and the bypass AC source (M2). Servicing by the after-sales support department is required. The buzzer sounds continuously.

OVERLOAD

RATED CURRENT PER PHASE = XXX A

CHECK LOAD LEVEL

This display informs the user that load cur- rent is greater than rated current, and gives the value. The buzzer sounds con- tinuously.

UPS SHUTDOWN DUE TO AN

OVERLOAD,

CHECK LOAD LEVEL

This message follows the preceding when the overload persists. The UPS has shut down and the buzzer sounds continuously.

INVERTER NOT IN PHASE WITH MAINS 2.

TRANSFER DISABLED, CHECK MAINS 2

The phase difference between the inverter and the bypass AC source (M2) is outside tolerances. Transfer of the load between the inverter and the bypass AC source

(M2) will result in an interruption in the sup- ply of power to the load.

For parallel UPSs, this message should be interpreted as meaning the phase differ- ence between the inverter for which the message is displayed and the other invert- ers is outside tolerances.

UPS SHUTDOWN

BY AN EXTERNAL COMMAND

The inverter has received a command to shut down. The command is in the form of a signal from received the remote-indica- tions relay board which has been set for this function.

n the inverter is started again.

MAINS 2 INPUT SWITCH Q4S IS OPEN

The bypass AC source (M2) input switch Q4S is open, i.e. backup power for the load via the bypass AC source (M2) is not available.

INVERTER OUTPUT SWITCH Q5N IS OPEN

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

This design enables users to customize the power capacity according to their specific needs, accommodating future growth without requiring a complete system overhaul. The modular architecture consists of interchangeable power modules that can be easily added or replaced, ensuring minimal downtime and optimized performance.

The Galaxy PW uses cutting-edge double-conversion technology, which provides a high level of power quality and reliability. This technology ensures that any fluctuations in input power do not affect the output, delivering clean and stable electricity to connected equipment. This is particularly essential for sensitive electronics that require a consistent power supply to function correctly.

Another significant characteristic of the Galaxy PW is its energy efficiency. The UPS is designed to operate at high efficiency levels, often exceeding 96%. This not only helps in reducing the overall energy consumption but also lowers operational costs and reduces the carbon footprint of the facility. The Eco-Mode feature allows the UPS to deliver power with minimal energy loss during normal operating conditions.

The Galaxy PW is equipped with advanced communication and management features, including an intuitive graphical LCD display that provides real-time information on the system's status and performance metrics. Users can monitor input and output voltages, current load levels, and battery health at a glance. Additionally, the UPS supports various communication protocols and interfaces, facilitating integration with building management systems and remote monitoring tools.

Safety and reliability are also top priorities for the Galaxy PW. The system features robust battery management to extend the lifespan of the batteries while ensuring optimal performance. The UPS is designed with several protections, including overload, short-circuit, and thermal protection, to safeguard both the UPS and connected loads.

In summary, the MGE UPS Systems Galaxy PW integrates modularity, energy efficiency, advanced monitoring, and robust protection features to deliver unmatched reliability for critical power applications. Its innovative design and technologies make it an ideal choice for businesses seeking a reliable power protection solution.
