VAU 01.1
The UPS NT Control software and the settings of the UPS times and delay times
(rotary switch S1), which might have to be adjusted, are described in the docu-
mentation of the panel PCs or control cabinet PCs (see section "Further docu-
ments" in chapter 1 "About this Documentation" on page
ter 12.6 "Rotary Switch S1" on page
Recommended rotary switch positions (S1) for the different UPS variants:
VAU 01.1U (from technical index GC1)
●
Recommended rotary switch position 8 or 9 with simple mode connection
and fallback for the IPC series:
– VPxxx.3xxx-xxxNN-D1D-xN-NN-FW; from February 2014 1st generation
– VPxxx.3xxx-xxxNN-D2D-xN-NN-FW; from February 2014 1st generation
– VPxxx.3xxx-xxxNN-xxD-xN-NN-FW; 2nd generation
The connection "U" at IPC has to be wired (see
tion: Connection scheme with power supply unit, UPS and panel PC or con-
trol cabinet PC for normal mode with fallback and simple mode" on page
Thus, the fallback mode is enabled in the IPC.
Advantage: An extreme EMC interference, influencing the USB connection be-
tween UPS and IPC does not result in an immediate PC shut-down.
The UPS buffers until the IPC has shut down (integrated monitoring and
emergency switch off of the UPS if the IPC does not shut down in case of
error).
Important: The set time has to be greater than the time the PC requires for a
controlled shut down. A sufficient reserve has to be taken into consideration.
The checkbox "Enable Shutdown on COM fail" must not be activated in the
UPS software (UPS NT Control Software) running on the IPC.
Disadvantage: If the time span is too short, uncontrolled standstill of the sys-
tem can occur. Sporadically, the IPC cannot be started anymore due to loss
of data.

Recommended rotary switch position 1 to 3 with simple mode connection

tween UPS and IPC does not result in an immediate PC shut-down. The UPS
buffers the set time.
