●
Buffer time
The time to be buffered by the UPS. The "Buffering allowed" parameter is used to specify
whether buffering should be performed.
●
Additional buffer time after PC shutdown
Time, to be buffered by the UPS1600 after the PC has been shut down.
●
Connection threshold
If the connection threshold value is undershot, the UPS starts buffering. If the value of the
connection threshold is reached or undershot again later, the UPS stops buffering.
●
Stop buffering voltage
The voltage at which battery discharge is terminated.
●
Wait time for stable input voltage
The time in which no alarm is issued to the system although the connection threshold
was undershot.
●
Downtime alarm
The time in which no alarm is issued to the system although it is buffered.
●
Buffering allowed
Select between buffers with the specified values or passive measurement of the power
supply by the UPS.
●
Enable reset after buffering
If the value is set to "Yes", after the line supply returns during buffering, the system issues
a reset – and switches the output off for a defined time. 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.

●
Faulty battery voltage
If the battery voltage undershoots this value, it is considered as being faulty by the
UPS1600 and not charged.
●
Battery capacity
If no UPS1100 battery modules are being used: Enter the total capacity of the installed
batteries.
●
Ignore data of coded battery
Set the value to "Yes" if no UPS1100 battery modules are being used.
