Pact_out-ovl = Pout x 0,8
Where:
-
Pact_out-ovl is the Overload Output Active Power (W)
-
Pout is Rated Output Apparent Power (VA)
Screen 4.3
: This alarm appears when the unit input is in mains failure condition and the battery level is lower
than 11,5V/bat.
Screen 4.4
: This alarm appears when the inverter output voltage phase to neutral in any phase is outside
range of +/-6%.
Screen 4.5
: This alarm appears when there is an offset voltage higher than 5V, in any phase of the inverter
output voltage phase to neutral.
Screen 4.6
: When the maintenance bypass switch is ON the UPS inverter will not be available.
Screen 4.7
: The mains failure occurs when in any phase, the input voltage phase to neutral is outside the set
margins (+15%/–20% by default) or the input frequency is outside the set margins (± 0,5Hz by default).
Screen 4.8
: When the inverter or PFC temperature sensors measure temperatures over the programmed
values (70ºC by default).
Screen 4.9
: This message appears when the battery switch is OFF and the DC bus is charged to the battery
voltage level, to inform the user to switch ON the battery switch.
Screen 4.10
: This screen indicates that the bypass input voltage or the bypass input frequency are outside the
margins. These margins are programmable but the default bypass voltage range is +12%/–17% and the
bypass frequency range is ±0.5Hz.
Screen 4.11
: The UPS is on bypass for whatever reason. It must be restarted via the display keypad.
Screen 4.12
: This is an alarm for parallel systems. It appears when UPS devices in the parallel system are
blocked because the maintenance bypass switch of a unit is switched ON.
Screen 4.13
: This alarm indicates that the CAN BUS #1 fails. This communication channel is used for remote
control.
Screen 4.14
: This alarm indicates that the CAN BUS #2 fails. This channel is used for data communication
between UPS devices, in a parallel system.
Screen 4.15
: This alarm appears at the estimated end of life of the battery bank. The revision and
replacement of some batteries will be required by calling the S.T.S. (Service and Technical Support)
department.
Screen 4.16
: The temperature of the battery cabinet (in the case of a separate battery cabinet) or battery lace
(if batteries located inside the UPS) is higher than 40ºC.
Screen 4.17
: If battery test (automatic or manual) is completed unsuccessfully, this alarm will appear.
Screen 4.18
: Two possible reasons:
During the unit start up, a message appears indicating that the battery switch can be switched ON.
After a period of time without switching ON, this alarm appears.
When the unit is running under normal conditions and the battery switch is switched OFF.
Screen 4.19
: When mains is connected during the start up, a phase rotation error is detected and the start up
procedure is inhibited.
Screen 4.20
: When the bypass is connected during the start up, a bypass phase rotation error is detected and
the start up procedure is inhibited.
Screen 4.21
: This alarm appears when in any phase, the rectifier input voltage phase to neutral is outside the
set margins (+15%/–20% by default) or the rectifier input frequency is outside the set margins (± 0,5Hz by
default). Then the rectifier is shut down.
Screen 4.22
: This alarm appears when any IGBT in the rectifier side modifies the number of times
programmed by display (50 by default).
