3-5 Starting the Industrial PC and
Procedure after Power Interruption
Make sure that the power supply connected to the NSA-series Industrial PC
satisfies the following specifications for NSA-series Industrial PC startup and
power interruption.
3-5-1 Operation
Starting the Operating System
If the external 24 V DC input voltage is turned OFF, the NSA-series Industrial PC
operating system will start up when the rated input voltage is supplied to the NSA-
series Industrial PC. The input voltage must remain OFF for at least 10 s before it
is turned back ON. (OFF/ON interval: 10 s min.)
Shutting Down the Operating System
The NSA-series Industrial PC shuts down the operating system when it receives a
shutdown request from a software application, or when the user executes a
shutdown operation. When the shutdown is completed, the NSA-series Industrial
PC will turn OFF all DC outputs except the 5-Vs auxiliary power supply.
Power Interruptions
If the 24 V DC input voltage from the external power supply is interrupted, all
NSA-series Industrial PC power supplies, including the 5-Vs auxiliary power
supply, will turn OFF. If this occurs during any operation, including shutdown, that
operation may not be successfully completed. Be sure to turn OFF the external
24 V DC input voltage after the shut down is completed. The NSA-series Industrial
PC does not have UPS or other recovery functions for power outages or power
interruptions. These functions will have to be provided externally (on the system
side).
Note
Confirm the safety of the system before turning the power ON or OFF.
