Operation Start-Up; Shift To Booster Or Fader Mode (During Voltage Variations In The Ac-Input Power) - MGE UPS Systems Pulsar Evolution 1100 Tower Installation And User Manual

3. Operation
3.1 Start-up
Note: The battery is charged as soon as the UPS is connected to the AC-power source, even if button 10 is in the OFF
position.

Press the ON / OFF button 10 .
The buzzer beeps and all the LEDs come ON.
The buzzer beeps twice during the self-test, then button 10 remains ON,
10
indicating that the receptacles are supplied with power.
- AC power is present: Only button 10 is ON. The protected equipment
11
is supplied by the AC-power source.
- AC power is absent: Button 10 and LED 11 are ON. The protected
12
equipment is supplied by the UPS, operating on battery power.
All the connected equipment is supplied with power.
If button 10 or LED 11 are not ON or if LED 12 is ON, there is a
fault (see section 4.1).
The booster and fader functions maintain the output voltage supplied by
the UPS within close tolerances around the rated value even if significant
voltage variations occur in the AC-input power. This avoids calling on bat-
tery power.
The values defining the voltage range may be set using the UPS Driver
software.
During operation in booster or fader mode, LED 16 is ON, signalling a
significant voltage variation in the AC-input power.
