3.4 SIMATIC STEP 7
● Buffer time
Time where the system is to be buffered by SITOP UPS1600. The "Buffering allowed"
parameter is used to specify whether buffering should be performed. If a value of 32767
is entered, then the SITOP UPS1600 interprets this as MAX, and only shuts down the
buffering when the stop buffering voltage is reached.
● Additional backup time after the PC has been shutdown
The time to be buffered by the SITOP UPS1600 once the PC has been shut down.
● Connection threshold
If the connection threshold value is fallen below, the SITOP UPS1600 starts buffering. If
the value of the connection threshold is subsequently exceeded again, then the
SITOP UPS1600 stops buffering.
● Stop buffering voltage
The voltage at which battery discharge is terminated.
● 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.
● 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 SITOP UPS1600.
● Activate reset after buffering
If the value is set to "yes", then, in the meantime, if the input voltage returns after the
buffer time has expired, the SITOP UPS1600 shuts down the output for the selected
interrupt time.
Battery parameters
Parameter
Faulty battery voltage
Battery capacity
Ignore data of coded battery
● Battery defective voltage
If the battery voltage undershoots this value, it is considered as being defective by the
SITOP UPS1600 and is 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 you define the parameters for the UPS1100 yourself.
