9 Software
9.1 Application Software of the Monitoring Functions
9.1.1 Temperature Monitoring
The surrounding air temperature of the VPB 40.1 must not 45 °C. To
ensure operational reliability, the control cabinet PC features a temperature
monitoring that measures the internal housing temperature.
1. For temperatures > 50 °C in the housing a temperature warning is indica‐
ted:
●
via the red flashing LED on the front panel of the VDP or
● via a message window displayed by the operating system. This mes‐
sage is also to be evaluated by all application programs, especially
by I/O processes.
The temperature warning can be disabled by the program UPS NT for
Windows (see chapter "UPS NT Program " on page 60 ).
2. For temperatures greater than 65 °C the system is always shut down and
switched off via the UPS logic (see chapter 9.1.2 "Uninterruptible Power
Supply (UPS)" on page 59 ). This applies for all VPB 40.1 housing var‐
iants.
Uncontrolled machine movements!
DANGER
Always ensure that temperatures remain within the non-critical range. In the
case of application-sensitive procedures, ensure that machine movements are
terminated in a controlled manner before the temperature monitoring function
switches off the VPB 40.1.
9.1.2 Uninterruptible Power Supply (UPS)
General Information
Malfunction of the UPS due to software not in‐
stalled or wrongly installed.
NOTICE
The uninterruptible power supply is only ready for operation, if the correspond‐
ing software is installed. If necessary, the UPS NT software can be installed
with the BRCVInstall installation software on the VPB 40.1. The software can
be accessed via a desktop icon.
Operating Principle of the UPS
In the event of a voltage breakdown or if the temperature exceeds 65 °C the
UPS logic of the VPB 40.1 power supply unit allows a safe operating system
shutdown by means of an battery pack.
In the event of a voltage breakdown > 20 ms, battery operation is activated
(provided that the battery pack is ready for use).
