• Expected buffer current
Load current, which is expected at the device output during buffer mode. Please adjust
the correct application load current required. For current settings between 0 A and rated
current, the display in the diagram "Remaining buffer time" is adapted. If a value of 0 A is
entered, then for this parameter, the average value of the actual load current measured at
the output over the last 10 min is assumed. The value of this parameter is used when
calculating the remaining buffer time. The entered value may not exceed the rated device
current.
Note
From the instant in time when the SITOP UPS1600 is switched over into the buffer mode,
the buffer current actually measured is used to determine the expected buffer time
instead of the expected buffer current.
• Battery test interval
Interval between performing battery tests.
• Activate reset after buffering
If this option is activated, the output voltage is interrupted after the selected buffer time
expires if, in the meantime, the input voltage returns. This option is useful, when, for
example, computer networks are protected by the UPS that can be activated by a reset
when the power supply is restored. For buffer time "MAX", the output voltage is not
interrupted.
• Reset time
Duration of the output voltage interruption.
• Reset to initial values
Reset all parameters of this area to default setting values.
Signaling
Parameter
Downtime alarm
Wait time for stable input voltage
Reset to initial values
• Downtime alarm
The time in which no alarm is issued to the system although it is buffered.
• Wait time for a stable input voltage
Time where the input voltage must continually lie above the connection threshold so that
buffering is exited and a transition is made into normal operation.
• Reset to initial values
Reset all parameters of this area to default setting values.
