Caution
Ensure that there is no condensation on or inside the Panel PC when
transporting it at low temperature or when it is exposed to
temperature fluctuations.
Before switching it on, the Panel PC must be brought to room
temperature slowly. In case of condensation, wait approximately 12
hours before switch the Panel PC on.
6.1 Power on
The power supply inside the Panel PC is ATX standard. The power on sequence
follows the ATX specifications.
•
The 5Vsb is a stand-by output that is active whenever the 115/230Vac power
input (or 24Vdc opt.) is present . 5Vsb provides a power source for circuits that
must remain operational when the main DC outputs are in disable state (e.g.
soft power control).
•
When the power button is pressed the main DC outputs are enabled and the
Panel PC starts the boot sequence.
If the “Restore AC Power Loss” in the BIOS Setup is set ON, the power on
sequence is executed automatically (without pressing the power button) whenever
the power input is switched on.
An Auto power-on jumper on the motherboard can bypass the BIOS Setup
(default). In this case isn’t necessary to set to ON “Restore on AC Power Loss”.
If the computer is switched on by power input then the boot starts about 5
seconds after power on.
Notice
Whenever the battery loses power, system settings (BIOS Setup)
stored in CMOS RAM are cleared. If the Auto power-on jumper isn’t
installed you must press the power button to switch the Panel PC on
(soft power).
Caution
Detach power plug before to open the Panel PC.
5Vsb could be active!
