55 Automation PC 620 User's Manual V 1.90
2.4.1 How do you determine the maximum environmental temperature?
1) Selection of the CPU board (use with or without fan kit).
2) The "maximum environmental temperature" line shows the maximum environmental
temperature for the entire system when using this CPU board.
3) Incorporating additional drives (add-on, slide-in), main memory, additional insert cards, etc.
can change the temperature limits of an APC620 system.
If there is a "
✓
" (checkmark) next to the component, it can be used at the maximum
environmental temperature of the whole system without problems.
If there is a specific temperature, for example "35", next to the component, then the
environmental temperature of the whole system cannot exceed this temperature.
Special case: 5AC600.HDDI-00, 5AC600.HDDS-00 and RAID hard disks
For these hard disks, the limits will depend on whether the system is intended for 24-hour
1)
or
standard
1)
operation.
Example 1: A temperature limit of "30/35" means
30 °C for 24-hour operation and 35 °C for standard operation.
Example 2: A temperature limit of "-/25" means
not intended for 24-hour operation and 25 °C for standard operation.
2.4.2 Temperature monitoring
The APC620 has temperature sensors in various places (I/O, power supply, slide-in drive 1,
slide-in drive 2). The locations of the temperature sensors can be found in figure "Temperature
sensor locations" on page 459. The value listed in the table represents the defined maximum
temperature for this measurement point
2)
. When this temperature is exceeded, an alarm is
triggered. The temperatures
2)
can be read in BIOS (menu item "advanced" - baseboard/panel
features - baseboard monitor) or in Microsoft Windows XP/embedded, using the B&R Control
Center.
Additionally, the hard disks for APC620 systems available from B&R are equipped with
S.M.A.R.T, or Self Monitoring, Analysis, and Reporting Technology. This makes it possible to
read various parameters, for example the temperature using software (e.g. HDD thermometer -
freeware) in Microsoft Windows XP/embedded.
1) 24-hour operation = 732 POH (Power On Hours) per month, standard operation = 250 POH or 333 POH (Power On Hours) per month.
Information:
It is generally recommended to use a fan kit when using hard disks 5AC600.HDDI-
00, 5AC600.HDDS-00 and the RAID hard disks.
2) The measured temperature is a guideline for the immediate environmental temperature, but can be influenced by neighboring
components.
