12.6 Rotary Switch S1
12.6.1 General Information
The switch position is in the delivery status "3".
UPS times
The UPS time is the time period in which the connected device is provided with
output voltage of the UPS – after switching off the input voltage. Set different
UPS times by S1 rotary switch . Change UPS times in steps of 60 seconds by
switch positions 0 to 3 and 4 to 9.
Time delay
This time delay prevents that "UPS operation" is signalled to the connected PC
and initiated during the first 120 seconds after switching on if the input voltage
is switched off within these 120 seconds.

Tab. 12-2: Settable UPS times and time delays
Switch position 1 to 3, 8, 9 (for production mode)
For switch positions 1 to 3, 8, 9, the time delay (120 seconds), which is integra-
ted in the UPS, is activated. This time delay prevents that "UPS operation" is sig-
nalled to the connected PC and initiated during the first 120 seconds after
switching on if the input voltage is switched off within these 120 seconds. Nev-
ertheless, the output voltage of the UPS is buffered by the integrated battery
and thus remains available for the connected PC. After the first 120 seconds
time delay, "UPS operation" is signalled to the connected PC and is initiated if
the input voltage remains switched off. In case of a voltage failure, the set UPS
time is active (switch position 0 to 3,8, 9. Thus, it is ensured that a voltage fail-
