4.2.3 Menu 2: Measurements
In order to access this screen, press ENTER in position "2. Measurements" in the main menu.
The operator can then check the value of the following electrical measurements using the
< or > arrows:
V phase/neutral = Voltage (Y) of the power supply input.
„
V phase/phase = Line voltage of the power supply input.
„
Input current = Input current from the Power Line.
„
V phase/neutral = Voltage (Y) of the output.
„
Output current = UPS output current.
„
Frequency = Frequency of the input voltage, Reserve line and UPS output.
„
Battery V, I = Battery voltage and current (+/-).
„
Temperatures = Temperature of the PFC, inverter and external battery (optional).
„
NOTE!
If the operator does not take any action for 3 minutes, menu "1. UPS STATUS
and ALARMS" is displayed automatically.

Table 4.4: Possible alarms of the equipment
The PFC is off or not working
The load is directly fed by the reserve line
The inverter is out of operation due to an overload, and the load is fed by the reserve
line
After 3 unsuccessful attempts to automatically switch from the reserve to the inverter,
the UPS locks the static switch in the reserve line position
With the battery voltage at 640 Vdc (380 Vac equipment) or 396 Vdc (220 Vac
equipment), the UPS warns the user that the battery voltage is low
When the voltage reaches 600 Vdc (380 Vac equipment) or 378 Vdc (220 Vac
equipment), the discharge ends, and the UPS is automatically turned off. The load is
then supplied by the reserve line, when available
Message displayed whenever the periodic battery test fails for any reason
The manual Bypass switch was closed
The mains is not compatible with the UPS specifications, the voltage may be out of
the range allowed by the system, or simply not present
The reserve line is not compatible with the UPS specifications; the voltage may be out
of the range allowed by the system or simply not present
This alarm occurs when there is no data exchange between the UPSs in parallel for
any reason. That may occur due to a connection fault between the fiber optic cables
At least one of the output phases is not present
Displayed whenever the emergency pushbutton is pressed for any reason
