● Location: Details of the location identification where the SITOP UPS1600 is installed.
● Connection threshold: If the connection threshold value is fallen below, the
SITOP UPS1600 starts buffering. If the value of the connection threshold is reached or
undershot again later, the SITOP UPS1600 stops buffering.
● Buffer time: Length of time during which the system should be buffered by the
SITOP UPS1600.
● Maximum buffer time: The MAX setting means that buffering is realized for as long as
possible. The device only shuts down when the battery has discharged down to the
defined stop buffering voltage. The value entered for the "Buffer time" parameter is not
relevant in this case.
● Additional buffer time after PC shutdown: The time in which the system is buffered by the
SITOP UPS1600 once the PC has been shut down.
● Expected buffer current: Load current, which is expected at the device output during
buffer operation. 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,
to determine the expected buffer time, instead of the expected buffer current, the actually
measured buffer current is used.
● Reset time: Time, in which the output voltage of the SITOP UPS1600 is switched off,
although in the meantime the input voltage has returned. This function allows IPCs to
automatically restart.
● Enable reset time after buffering: If the value is set to "Yes", the SITOP UPS1600 shuts
down the output for the selected interrupt time if, in the meantime, the input voltage
returns after the buffer time has expired. Using this function, after the SITOP UPS1600
has been powered down, an IPC can be switched on again, for example.
