3.3 UPS program
3.3.1 Functions
The “UPS
plus
” or “UPS
NT
” uninterruptible power supply program controls
and monitors the integrated uninterruptible power supply (UPS). The
program also checks the function of the battery pack, and controls
temperature monitoring of the system.
In the case of the IPC300, the program also monitors fan functions and inter-
nal operating voltages.
Depending on the type of IPC and its operating system, one of the following
is installed:
D
UPS
plus
for IPC with Windows 95
D
UPS
NT
for IPC with Windows NT
D
UPS
NT
for IPC300 with Windows NT
The UPS program is always connected to the UPS via the COM4 serial port.
The occurrence of a voltage drop/interruption causes the UPS program to
respond as follows:
D
By sending, within a preselected interval (Delay Time = max. 50
seconds), a signal to all active applications, facilitating their safe
shutdown by the user / operator or via special application routines.
D
By following the expiration of the Delay Time by shutting down the operat-
ing system.
Once the UPS power monitoring function has been triggered, aborting
the system shutdown routine is no longer possible.
Closing all active applications prevents data loss in the event of a sudden
voltage interruption.
If the mains voltage has not been restored, the UPS switches off the IPC
power supply after a maximum 60 seconds (see disconnect conditions in
Section 3.2).
CAUTION
Loss of data through manual restart!
Note that the USP switches off the operator terminal in any case. For
thus reason, once the operating system has been shut down, the
“Restart” dialog button must not be selected.
In the case of voltage interruptions below 60 seconds, the operating
system is restarted automatically.
The operator cannot access the UPS
plus
or UPS
NT
program during standard
operation. Operation and settings are not possible without special access
rights (as User or Administrator), and not until the operating system has
been restarted.

Parameter values set in UPS
plus
or UPS
NT
may not be changed without
prior consultation with Bosch Rexroth AG.
