NOTICE
The UPS logic of the VPB 40.1 power supply unit is designed for a safe shut‐
down of all application programs and the operating system. The UPS logic is
not designed to maintain the operation during a longer voltage loss!
DANGER
If there are no batteries in the unit or if the batteries are defective or discharged,
the VPB 40.1 is RESET after a voltage breakdown > 20 ms!
Uncontrolled machine movements or a data loss can be caused.
If the duration of the voltage breakdown is below 800 ms, the power supply unit
switches automatically from battery mode to normal mode.
If the voltage breakdown is > 800 ms, the operation system initiates a system
shutdown after a selectable time (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 voltage breakdown lasts longer than 60 seconds, the UPS switches off
the power supply unit.
Setting the Delay Time in the UPS NT additional software, see
chapter "UPS NT Program " on page
The UPS NT program controls and monitors the integrated uninterruptible pow‐
er supply (UPS). Additionally, the program features the following functions:
●
Monitoring the system temperature in the device
●
Monitoring the function of the fans
●
Monitoring the internal operating voltages
●
Checking the charging status of the batteries, if required
●
Setting the COM interface for the keyboard controller
●
Setting the SIS interface mode
The communication between program and UPS occurs via the serial interface
COM4.
The program consists of two parts:
1. Control Panel Applet
2. Actual Windows NT service
In the event of votlage breakdown within a settable time (Delay Time: 60 sec‐
onds max.) the UPS program has the following tasks:
●
Sending a message to all active applications so that the user or special
application routines can close them.
●
Shutdown the operating system after the expiration of the Delay Time.

Possible damage of connected machines if the
VPB 40.1 is switched off after at least three
minutes by the UPS hardware in the event of
power failure and UPS operation.
Uncontrolled machine movements or data loss
due to defective batteries.
