Emergency Power Off
In case of serious system halt due to any reason, the system could fail
to be powered off through normal means. Press and hold the Power ON/OFF
Switch for Emergency Power Off. Release the switch after the system powered
off. It will take about 10 seconds. If there appears to give a special coded beep
tone in the pattern “short, long, short, long, short” prior to the system power
off in this process, please remove the AC power and wait for few minutes to
allow the hardware registers to reset (If there is no such beep, AC removal is
not required). Then you may restart the system and take remedial action
against the precious failure.
UPS Function
When the UPS battery is installed, this function can be automatically
enabled if the machine is operating on the preloaded OS from the manufacturer.
When the external power is interrupted during system operation with the UPS
function enabled, the system will give periodical beep to indicate the status of
system working on battery power. The beep will go rather fast when the UPS
battery approaches a fully discharged condition to remind the operator that
power will soon finish. In few seconds, the whole system will soon be
automatically turned off. In case the AC power resumes during the usage of
the battery power, the battery operation will keep on for few seconds before
the AC supply is confirmed stable.
CUSTOMER DISPLAY
The optional customer display PD-2601 or PD-7321 mounted on a
pole at rear corner of PB system can be turned horizontally for best viewing
effect in application.
FAN CONTROL
In the preloaded OS for this PB system, there is an embedded function
that can keep on monitoring the interior temperature and the fan revolution rate
and regulating each required fan power to gain
maximum ventilation effect with lowest possible
noise. This function is disabled by default at
delivery. The user can decide to engage this
function by clicking “Start” --> “Programs” -->
“Posiflex Tools” --> “Posiflex Fan Control” to
pop up a window like the right picture. Click
“Enable” then “Apply” to engage this function
in background. This function will remain
operating even after system restart. To disable this function, you have to pop
up this window again and click “Disable” then “Apply” and restart the system.
If system hang due to CPU overheat occurs, please review the ventilation
