If the duration of the voltage breakdown is below 800 ms, the power
supply unit switches automatically from battery operation to the normal
operating mode.
If the voltage breakdown is greater than 800 ms, the operation system
initiates a system shutdown after a selectable delay time. This delay time
shall be used to close all active applications by the user or by special
routines.
If the supply voltage is available again within 60 seconds, the UPS
interrupts the operating voltage for further 8 seconds. After that, the
operating system is rebooted.
If the interruption of the supply voltage lasts longer than 60 seconds, the
UPS switches off the power supply unit.
Note: Set the delay time in the additional software "UPS
page 9-2).
Functionality
The program "UPS " serves to control and monitor the integrated
NT
uninterruptible power supply (UPS). In addition, the program has the task
to:
• monitor the system temperature in the device
• monitor the function of the fans
• monitor the internal operating voltages
• check the charging status of the batteries, if required
• Select PROFIBUS Address
• set the COM interface for the touch screen controller
• set the SIS interface mode
The communication between program and UPS occurs via the serial
interface.
The program consists of two parts, a Control Panel Applet and the
Windows NT service.
The task of the UPS program is in case of a voltage breakdown within a
determinable time (delay time: maximum 60 seconds) to
• send a message to all active applications, so that they can be closed
by the user or via special user routines and
• to shutdown the operating system after the expiration of the delay
time.
Once the voltage monitoring is activated, it is not possible to stop the
system shutdown.
Closing all active applications prevents data loss in the event of an
unexpected voltage interruption. After a maximum of 60 seconds the USP
switches off the PC power supply unit, if the supply voltage has not been
restored (see Switch Off Conditions on page 9-1).
In the normal mode the user has no access to the UPS
the user has special access rights and after re-starting the operating
system operation is possible and settings can be made.
Note: Modifications of the parameters set in the UPS
carried out after consulting Bosch Rexroth.
