Version 1.0.0
If the set delay time expires before power is restored, the output voltage and
signal output are switched as shown in the flow chart below:
Figure 13: Flow chart – "Input voltage not restored before set delay time expires."
6.6.3.2 Shut Down PC
The signal output "Bat. Mode" is activated when the set delay time expires. This
signal must be routed to an IPC connected to the system, a control system or a
display and operator panel so that the device in question can be shut down in a
controlled manner. The signal output remains activated until the time set in the
field "Shut down PC" expires. Ample time should be allowed for by this time
setting.
6.6.3.3 PC Idle (Off) Time
The output voltage is de-activated when the time set in the field "Shut down PC"
expires. The time at which the output is re-activated depends on whether power
supply has been restored:
•
If voltage is restored before the time set in the field "Shut down PC"
expires, the output is re-activated when the idle time has also expired. This
ensures that the devices connected to the system cannot be restarted
immediately after shutdown, even when power has been restored in the
meantime.
•
If voltage has not been restored before the time set in the field "Shut down
PC" expires, the output is not re-activated until the voltage is restored.
