Inverter on button | MGE UPS Systems Galaxy PW manual

Galaxy PWTM 100 to 225 kVA

"Load" light 5

■light off: load not supplied;

■light shines green: load supplied via the inverter or the bypass AC source (via the

static bypass).

Buzzer 6

The buzzer sounds in the following situa- tions:

■ load supplied by the bypass AC source;

■ load on battery;

"V" key 13

This key is used to access voltage mea- surements:

■normal AC source phase-to-phase volt- ages;

■bypass AC source phase-to-phase and phase-to-neutral voltages;

■load phase-to-phase and phase-to-neu- tral voltages.

"Alarm reset" key 20

This key is used to reset stored alarms. The system accepts resetting only when alarms have been cleared.

"Buzzer reset" key 21

This key is used to stop the buzzer. However, new alarms set the buzzer off again.

■ operating problems.

It sounds slowly and discontinuously for a minor problem or when the inverter is on battery power.

When the alarm "LOW BATTERY SHUT- DOWN" is activated, the buzzer sounds more rapidly. Finally, if the inverter shuts down, the beep is loud and continuous. The buzzer may be reset by pressing a button. If the buzzer is reset, a higher level alarm will set it off again.

"Inverter ON" button 7

This button is used to start the inverter locally.

"Inverter OFF" button 8

"A" key 14

This key is used to access current mea- surements:

■normal AC source, bypass AC source and load currents;

■percent load;

■load crest factor.

"W.Hz" key 15

This key is used to access other measure- ments:

■normal AC source, bypass AC source and inverter frequencies;

■level of active and apparent power drawn by the load;

■load power factor;

■inverter load level (percent).

"Anomaly" indicator light 16

This indicator light indicates the presence of anomalies.

key 17

This key is used to access the primary messages.

"Battery" key 18

This key is used to access battery mea- surements:

■battery voltage (or the DC voltage on frequency converters without a battery);

■battery current (charge or discharge);

■battery temperature;

■available battery backup time;
