Input voltage DC 24 V on the UPS of the power supply unit.
24V Out
Output voltage DC 24 V of the UPS to supply the connected PC.

Timing depending on the position of S1 rotary switch: Overview
Switch position 0 to 3 => for production mode
Switch position 0 => UPS time "t" = 5 seconds
Switch position 1 => UPS time "t" = 60 seconds
Switch position 2 => UPS time "t" = 120 seconds
Switch position 3 => UPS time "t" = 180 seconds
Observe that the timing behavior depends on the switch position "and" on the
"Shutdown Delay Time", which is set in the "UPS-NT Control" software. Via
this software times from 1 second to 45 seconds can be set.

Signal to the connected PC that the UPS is in the buffer mode and

24V Out
Output voltage DC 24 V of the UPS to supply the connected PC.

Timing
If the input voltage on the UPS drops "after" the time delay of 120 seconds
has expired, the output voltage is buffered via the battery and UPS operation
is signaled to the connected PC. After the UPS time "t" has expired, the VAU
01.1U switches off the output voltage.
