failures that last for a longer period of time, the alarm message can then be used to
initiate other specific measures, for example, safely running down a PC.
● Waiting time until short-time interruption
The parameter is used to define the minimum time that must elapse after the "Buffer
operation" alarm message, before the output voltage at output 1 is interrupted when the
power supply returns during buffer operation. For instance, this can be the time that a PC
requires to safely run down.
● Duration of short-time interruption
The parameter is used to define the time for which output 1 is interrupted during buffer
operation when the power returns (for example to restart a PC after it has been run
down).

● Switch on output
Here, you specify whether the output is switched on.
● Setpoint output voltage
Define the required output voltage.
Using the "MANUAL >> REMOTE" button you load the value set using the potentiometer
at the front of the device into the REMOTE configuration of the system. If the button is
grayed out, this means that there is a connection to a control system.
● Response threshold of the output current
Define the required response threshold value of the output current for the particular
output.
Using the "MANUAL >> REMOTE" button you load the value set using the potentiometer
at the front of the device into the REMOTE configuration of the system. If the button is
grayed out, this means that there is a connection to a control system.
● Prewarning threshold output current
Using prewarning thresholds for the output current of the individual outputs, you can
identify at an early stage slight (creeping) changes in the current demand of the
connected load. This prewarning function facilitates the highest possible availability of the
system (maintenance function).
Enter a value of "0 %" to deactivate the prewarning threshold.
