A: Metering-
The GES-242N-R incorporates 4 digital displays for the user to monitor
their Voltages and Currents.
1.
Input AC voltage:
Detects the input AC, allowing the user to monitor the 480 VAC
required
to
power
the
UPS.
2.
Battery Current:
This ammeter detects both charge and discharge current of the
batteries. The ammeter has a range of +/- 200 ADC.
3.
DC Output Voltage:
Detects the DC output voltage supplied to the Load.
4.
DC Output Current:
This ammeter detects the output current on the main bus bar.
The ammeter has a range of +/- 200 ADC.
B: Warning LED’s-
When an abnormal condition occurs, these LED’s will illuminate allowing the
user to identify the fault. This will also allow the service personnel the ability
to troubleshoot the system. These LED’s are described below:
•
INPUT –
No AC Voltage is detected on the input of the UPS.
•
CHARGER -
The LED will illuminate continuously when the charger fails
to deliver the necessary voltage to charge the batteries. The LED will
flash if the Battery Breaker is open.
•
FAULT -
tells the operator that one or both DC rectifiers have failed and
to immediately shut the UPS down
•
BAT LOW -
This alert is designed to inform the operator that the battery
voltage is below 22.0 VDC and serve as a reminder to shut the system
down if the UPS is no longer needed.
•
BAT LOW STOP –
This alert is designed to inform the operator that the
battery voltage is below 20.5 VDC and that the UPS system should be
shut down immediately to prevent damage to the batteries.
•
OUTPUT -
The output status indicator is designed to inform the operator
of the status of the output breaker. If the breaker is open the red LED will
illuminate. Once the breaker is closed, the LED will go out.
•
FLOAT –
The Batteries are fully charged.
